Description

Technical Field

[0001] The present invention relates to components and smoking articles flavored with flavoring ingredients. Background Art

[0002] A cooling sensation component (i.e., a type of flavoring ingredient) such as menthol is added to a component of a smoking article, such as tobacco filler, to provide a cooling sensation in a combustion-type smoking article, a heat-not-burn smoking article (i.e., a heat-not-burn smoking article), a smokeless smoking article, or an electronic cigarette. This forms a component flavored with a flavoring ingredient (i.e., a flavoring-flavored component). Summary of the Invention

[0003] Technical issues

[0004] Smoking articles may also have requirements for cooling intensity, shelf stability, and bitterness characteristics as follows.

[0005] Cooling intensity

[0006] The stronger the cooling intensity of the cooling component, the less cooling component is needed to achieve a predetermined cooling intensity, thereby increasing the freedom to blend components other than the cooling component into the flavoring. If the cooling intensity of the cooling component is even stronger, the level of flavoring with the flavoring can also be reduced. Since this is advantageous from a manufacturing perspective, a cooling component with a greater cooling intensity is desired.

[0007] <Storage Stability>

[0008] Smoking articles may be used after being stored for a long period of time. Therefore, the component members of the flavoring component aromatization treatment must retain the cooling sensation intensity after storage (ie, must have excellent storage resistance in terms of cooling sensation intensity).

[0009] However, cooling components, such as menthol, are generally highly volatile. Commercially available smoking articles are typically stored in a closed system covered with a film package, such as polypropylene. However, cooling components such as menthol evaporate within the package and are ultimately absorbed into a different area from where they were originally added. Consequently, there is a problem: when smoking after opening the film package, the product experiences a cooling intensity different from the cooling intensity at the site where the cooling component was originally added.

[0010] In addition, after opening the film package, the film package becomes an open storage system, and the added cooling component evaporates into the air. In this case, there is also a problem that the amount actually used as the cooling component during smoking is less than the amount originally added, resulting in a product with a weak cooling intensity.

[0011] <Bitter taste>

[0012] It is known that if the amount of cooling component is increased to achieve the desired cooling intensity, both the cooling sensation and the bitterness are imparted. Therefore, there is a need for a cooling component that increases the cooling intensity without increasing the bitterness.

[0013] In view of these circumstances, the problem to be solved by the present invention is to provide a flavoring component having a strong cooling intensity, excellent storage stability and little bitterness.

[0014] Solution to the problem

[0015] As a result of intensive research to solve the above problems, the inventors discovered that these problems can be solved by using a cooling agent showing a specific retention index (RI) as a cooling component, and have perfected the present invention.

[0061] In this specification, the unit “ppm” indicates “ppm by weight.” Furthermore, “XY” indicating a numerical range is used in the sense that the first and last numerical values ​​stated are included as the lower limit and the upper limit thereof, respectively.

[0062] The following describes the components of the flavor ingredient flavoring treatment and smoking articles of the present invention.

[0063] 1. Components of flavoring ingredients

[0064] The components of the flavoring ingredient perfuming process of the present invention are:

[0065] A component for flavoring treatment of a flavoring ingredient, comprising a component for a smoking article and

[0066] A flavoring ingredient comprising a cooling agent (A) having a retention index (RI) of 1300 or greater in a chromatogram obtained by analyzing the cooling agent by gas chromatography-mass spectrometry (GC / MS) using a column having a stationary phase of 95% dimethylpolysiloxane and 5% phenyl-methylpolysiloxane,

[0067] The components of the smoking article are flavored with the flavoring ingredient.

[0068] 1-1. Seasoning ingredients

[0069] The components of the smoking article are flavored with the flavoring ingredient. In this specification, "flavoring" refers to the addition of a specific ingredient. There are no specific limitations on flavoring components of the smoking article with the flavoring ingredient, and this can be achieved by applying, mixing, inserting, or a combination of two or more of these. The flavoring ingredient can be used to flavor components of the smoking article or their precursors (raw materials).

[0070] <Cooling Agent (A)>

[0071] In a chromatogram obtained by analyzing the cooling agent using a gas chromatography-mass spectrometer (GC / MS) using a column having a stationary phase of 95% dimethylpolysiloxane and 5% phenyl-methylpolysiloxane, the cooling agent (A) has a retention index (RI) of 1,300 or greater, preferably 2,000 or greater, more preferably 2,400-2,600, and most preferably 2,300-2,600. By having an RI within the above numerical range, storage stability is excellent and the compound can be efficiently volatilized and inhaled during smoking.

[0072] <Retention Index (RI)>

[0073] In this manual, " retention index (RI) " indicates, with the carbon number of straight-chain hydrocarbons (n-alkanes) as standard, by gas chromatographic analysis, relatively represents the index of the retention ratio of n-alkanes and the analyzed compound.When using the post with a predetermined stationary phase, even if the length of the post, the carrier gas flow rate etc. change, the RI of the same compound will also be the same value in theory.Specifically, RI is calculated by the following equation.

[0074] Formula 1

[0075] RI=100n+100(t x -tn ) / (t n+1 -t n )n: carbon number of the n-alkane that appears as a peak immediately preceding the analyte compound peak

[0076] t x : Analyte compound peak retention time

[0077] t n : Retention time of n-alkanes that appear as peaks immediately preceding the analyte compound peak

[0078] t n+1 : Retention time of n-alkanes appearing as peaks immediately following the analyte compound peak

[0079] The RI used in this specification is a range from n-hexane (C6, RI: 600) to n-pentatriacontane (C 35 , RI: 3500) is calculated based on a normal alkane mixture, but the normal alkane mixture used for calculating RI is not limited thereto.

[0080] In this specification, the columns used in gas chromatography have, for example, a non-polar or low-polarity stationary phase, and preferably a non-polar stationary phase. In gas chromatography using these columns, it is believed that the lower the RI value, the greater the possibility of volatilization of the compound, and conversely, the higher the RI value, the less likely the compound is to volatilize.

[0081] For example, a column having a stationary phase of 95% dimethylpolysiloxane and 5% phenyl-methylpolysiloxane can be used as the column having a low-polarity stationary phase.

[0082] For example, HP-5MS (manufactured by Agilent Technologies) can be used as a column having a stationary phase of 95% dimethylpolysiloxane and 5% phenyl-methylpolysiloxane, but is not limited thereto.

[0083] For example, a column having a stationary phase of 100% dimethylpolysiloxane can be used as a column having a non-polar stationary phase.

[0084] For example, DB-1 (manufactured by Agilent Technologies) can be used as the column having a stationary phase of 100% dimethylpolysiloxane, but is not limited thereto.

[0085] Regarding the equipment and conditions used for gas chromatography-mass spectrometry (GC / MS), there is no particular limitation, but the equipment and conditions mentioned in the following examples can be used.

[0115] The methyl menthol derivative of the present invention represented by the above formula (1) can be synthesized based on well-known conventional methods (such as the method disclosed in WO2018 / 131575).

[0116] The methyl menthol derivative represented by the general formula (1) of the present invention has a strong cooling intensity, provides a continuous cooling sensation to the back of the throat, and can therefore be used alone as a cooling agent or a sensation-imparting agent. It is also known that many cooling components impart a bitter taste along with the cooling sensation, but by using the methyl menthol derivative represented by the general formula (1) of the present invention, a cooling experience with minimal bitterness can be obtained during smoking.

[0138] Although not particularly limited thereto, the polysaccharide may comprise or consist of a single-component system of one component selected from the group consisting of dextrin, oligosaccharide, starch, carrageenan, locust bean gum, guar gum, agar, gellan gum, tamarind gum, xanthan gum, tara gum, konjac glucomannan, cassia seed gum or plantain seed gum; or a composite system in which two or more components selected from the above group are combined.

[0139] Although not particularly limited thereto, the sugar may comprise or consist of a single component system of one component selected from the group consisting of sucrose, trehalose, maltose, lactose, glucose, and fructose; or a complex system in which two or more components selected from the above group are combined.

[0140] Although not particularly limited thereto, the sugar alcohol may comprise or consist of a single-component system of one component selected from the group consisting of reduced maltose syrup, sorbitol, mannitol, xylitol, erythritol, and maltitol; or a complex system in which two or more components selected from the above group are combined.

[0141] <Cellulose derivatives>

[0142] Although not particularly limited thereto, the cellulose derivative is preferably a cellulose derivative that is soluble in an organic solvent. The cellulose derivative herein refers to a derivative obtained by introducing a substituent of an OH group into cellulose, and examples include ethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose (e.g., hydrophobic hydroxypropyl methyl cellulose), and hydroxypropyl methyl cellulose phthalate. They are generally widely used as binders, film formers, and gelling agents due to complex effects caused by characteristic functional groups of the cellulose derivative. The organic solvent in the expression "soluble in an organic solvent" herein is, for example, ethanol.

[0143] The cellulose derivative is preferably an amphiphilic cellulose derivative, and more preferably hydroxypropyl cellulose. The degree of substitution in the hydroxypropyl cellulose is, for example, 0.1 to 4.5, and preferably 2.0 to 4.5. In the present specification, the degree of substitution in the hydroxypropyl cellulose represents the number of hydroxypropyl groups in each glucose. The hydroxypropyl cellulose that can be used is, for example, commercially available under the trade name Celny from Nippon Soda Co., Ltd.

[0144] The following describes advantages of using hydroxypropyl cellulose as the cellulose derivative. Hydroxypropyl cellulose is a derivative of cellulose, and is a substance obtained by substituting an OH group in cellulose with a hydroxypropyl group. Hydroxypropyl cellulose is widely used as a binder, a film former, or a gelling agent. Cellulose is a hydrophobic substance because OH groups are hydrogen-bonded to each other, thereby intermolecular crystallization occurs. On the other hand, hydroxypropyl cellulose has a hydroxypropyl group, which means that it is less likely to form hydrogen bonds between molecules therein, and thus is a substance that is both hydrophilic and hydrophobic (i.e., an amphiphilic agent).

[0145] It has also been reported that, in a system containing glycerol, a network-structured complex is formed by interaction (i.e., hydrogen bonding) between the hydroxypropyl groups of the hydroxypropyl cellulose and the OH groups of the glycerol. It is thought that, even when a flavorant other than glycerol is used, the hydroxypropyl cellulose can form a network-structured complex by interaction such as hydrogen bonding and hydrophobic interaction with the flavorant. It is also thought that, since the hydroxypropyl cellulose is amphiphilic, it can incorporate both hydrophilic and hydrophobic flavorants into the network structure without using an emulsifier or the like. It is thought that, when the tobacco product is stored, the flavorant is stably retained by this network complex without evaporating, and, when the tobacco product is used (particularly when a heat- smoking article is used), the flavorant is stably released.

[0146] Further, hydroxypropyl cellulose is soluble in organic solvents, particularly ethanol. Therefore, when a liquid composition containing hydroxypropyl cellulose, a flavor, and a solvent is used in the form of an ethanol solution, the ethanol solution is more advantageous than an aqueous solution in terms of manufacturing processes such as conveyance and coating, because the viscosity of ethanol can be reduced to a greater extent than that of water. Also, when the ethanol solution is dried and forms a flavor composition (hydroxypropyl cellulose film, etc.), the evaporation speed of the solvent is faster than in the case of an aqueous solution, and thus has advantages such as shortening of the manufacturing time and reduction of energy costs during drying.

[0147] <Non-pulp fiber>

[0148] A non-pulp fiber is a fiber other than a pulp fiber. A pulp fiber is an aggregate of cellulose fibers extracted from a plant such as wood, and is generally used as a raw material for paper. Examples of a pulp fiber include waste paper pulp, chemical pulp, and mechanical pulp. In the present application, a non-pulp fiber is preferably plant-derived. Because a fiber of plant origin is biodegradable, there is little environmental impact.

[0149] A component such as a conventional tobacco sheet is based on a pulp fiber such as wood pulp, i.e., a bundle of plant fibers (as in, for example, the specification of U.S. Patent No. 5322076). Wood pulp generally consists of a bundle of a plurality of filaments having a diameter of 20 pm, and has a fiber diameter of about 100-200 pm and a fiber length of about 1,000-2,000 pm. When a tobacco sheet having a practical tensile strength is manufactured using wood pulp, the sheet has a thickness of 100-300 pm, and thus its thermal conductivity is reduced. However, because a non-pulp fiber is used in the present application, a thin sheet having excellent mechanical strength can be formed, and excellent thermal conductivity can be achieved. From this perspective, the average fiber diameter of the non-pulp fiber is preferably 25 pm or less, more preferably 20 pm or less, and still more preferably 15 pm or less. There is no limitation on the lower limit of the average fiber diameter, which can be 2 nm or more, 10 nm or more, 100 nm or more, 1 pm or more, or 5 pm or more.

[0150] The average fiber diameter of the non-pulp fiber can be determined by obtaining an image of the fiber, measuring the width (i.e., the minor axis) of a plurality of fibers, and averaging these values. When the shape of the fiber is columnar (and the cross section is rectangular), the major surface width (i.e., the longer one of the two) is considered to be the width of the fiber among the major surface width and the side surface width. The number of fibers measured is preferably 100 or more.

[0151] The non-pulp fibers are preferably monofilament cellulose. Monofilament cellulose is a fine fiber obtained by subjecting pulp fibers to processing such as fiber separation. Monofilament cellulose can be chemically modified, for example, by oxidation. The average fiber diameter of monofilament cellulose is as shown above. Although not limited thereto, the upper limit of the average fiber length of monofilament cellulose is preferably 2,000 μm or less, and more preferably 1,500 μm or less. The lower limit is preferably 100 μm or more, and more preferably 500 μm or more.

[0152] The non-pulp fiber is also preferably a dietary fiber. Dietary fiber is a dietary component that is not digested by human digestive enzymes, and in the present application, it is more preferably an insoluble dietary fiber that is insoluble in water. The dietary fiber can be porous, i.e., sponge-like. Porous fibers can increase the surface area of ​​the sheet used for smoking products and improve the thermal conductivity of the sheet. In terms of availability, etc., the above-mentioned fiber is preferably citrus fiber. Citrus fiber is a fiber with citrus albedo as the main raw material. The average fiber diameter of citrus fiber is as shown above. Moreover, the dietary fiber can be a short fiber or columnar particles with a low aspect ratio.

[0153] In one aspect, monofilament cellulose and dietary fiber are used in combination. Use both to improve the intensity and water dispersibility of tobacco sheet and the amount of smoke from tobacco sheet. Relative to 1 weight portion of dietary fiber, the upper weight limit of monofilament cellulose is preferably 1.5 weight portions or less, more preferably 1.2 weight portions or less and the lower limit is preferably 0.1 or greater and more preferably 0.3 or greater.

[0154] <Lipids>

[0155] Although not particularly limited thereto, the lipid may be a solid wax, a ceramide, a derivatized fat such as a fatty acid, a complex lipid such as a phospholipid, or a mixture of two or more thereof.

[0156] The flavoring component containing the above-mentioned carrier can be a component that carries flavoring agents. In the case of the present invention, although not particularly limited thereto, the content of the carrier can be 1 ppm or more, 1,000 ppm or more, or 10,000 ppm or more of the entire flavoring component (i.e., the component that carries flavoring agents) containing the carrier. Alternatively, the content of the carrier can be 500,000 ppm or less, 400,000 ppm or less, or 300,000 ppm or less of the entire component that carries flavoring agents. The numerical range of the content of the above-mentioned carrier can be combined as desired. Due to the carrier content within the above-mentioned numerical range, an effective component that carries flavoring agents with a good balance between the carrying and release of the flavoring component is obtained.

[0157] <Emulsifier>

[0158] The flavoring component may further contain an emulsifier.

[0159] There is no particular limitation on the type of emulsifier, and for example, sorbitan monolaurate, such as 20 (available from Uniqema of Wilmington, DE, USA); poly(ethylene oxide) sorbitan monolaurate, such as 20 (available from Liquima, Inc., Wilmington, DE, USA); a glycerol fatty acid ester, such as glyceryl monostearate, decaglycerol monolaurate, or decaglycerol pentastearate; a sugar ester, such as sucrose monostearate or sucrose monopalmitate; a propylene glycol fatty acid ester, such as propylene glycol monostearate; lecithin; or a combination of two or more thereof.

[0160] Although not particularly limited thereto, the emulsifier content may be 1 ppm or more, 100 ppm or more, or 1,000 ppm or more of the entire flavoring component including the emulsifier. Alternatively, the emulsifier content may be 500,000 ppm or less, 400,000 ppm or less, or 300,000 ppm or less of the entire flavoring component including the emulsifier. The above numerical ranges for the emulsifier content may be combined as desired. Having an emulsifier content within the above numerical ranges allows the water-soluble components and oil-soluble components of the flavoring component to be efficiently emulsified and dispersed.

[0161] Although not particularly limited thereto, the flavoring ingredient may be in a liquid, semi-solid or solid state. If the flavoring ingredient is solid, it may be in the form of a powder, a capsule (such as a seamless capsule form) or a sheet.

[0162] <Aerosol Source>

[0163] The means of perfuming the flavouring ingredients may further comprise an aerosol source.

[0164] Although not particularly limited thereto, the aerosol source may be a polyol such as glycerol or propylene glycol, or for example triethylamine citrate or glyceryl triacetate, or a mixture of two or more thereof. Of these, glycerol is preferred. Using glycerol can effectively increase the amount of visible smoke.

[0165] Although not particularly limited thereto, the content of the aerosol source relative to the entire flavoring component aromatization component may be 1 ppm or more, 10,000 ppm or more, 50,000 ppm or more, or 200,000 ppm or more. Alternatively, the content of the aerosol source relative to the entire flavoring component aromatization component may be 990,000 ppm or less, 500,000 ppm or less, or 200,000 ppm or less. The above numerical ranges for the content of the aerosol source may be combined as desired. Having an aerosol-generating substrate content within the above numerical ranges can effectively increase the amount of visible smoke.

[0166] <Adsorbent>

[0167] The above-mentioned flavoring component aromatization component may further contain an adsorbent.

[0168] Although not particularly limited thereto, the adsorbent may comprise, for example, activated carbon, zeolite, or silica, or a combination of two or more thereof, or may consist thereof. Of these, activated carbon is preferred. By using activated carbon, the effect of reducing flavor-inhibiting substances is achieved.

[0169] The adsorbent content relative to the entire flavoring ingredient aromatization component can be set as desired, and although not particularly limited thereto, may be 1 mg or more. Alternatively, the adsorbent content relative to the entire flavoring ingredient aromatization component may be 300 mg or less, or 100 mg or less. The above-mentioned numerical ranges for the adsorbent content may be combined as desired.

[0170] 1-2. Components of Smoking Articles

[0171] Although not particularly limited thereto, the components of the smoking article may be a tobacco filler, a filter, a tube, cigarette paper, tipping paper, a plugging member, a packaging material, a liquid, or a combination of two or more thereof. Among these, the tobacco filler is preferred. Due to the use of the tobacco filler, an effective cooling sensation is obtained by the efficient heating and evaporation of the cooling agent.

[0172] [Tobacco filler]

[0173] In the predetermined aspect, tobacco filler refers to a fillable object filled with processed tobacco leaves. A "fillable object" is an object filled with processed tobacco leaves and is part of a tobacco product. Examples of fillable objects include, but are not limited to, cigarette paper formed into a cylinder and a container having an air inlet and an air outlet.

[0174] Examples of aspects of the fillable object filled with the processed tobacco leaf include aspects in which the processed tobacco leaf is rolled in a web to be inside the web (hereinafter referred to as "tobacco rod"), and aspects in which a container for the processed tobacco leaf has an air inlet and an air outlet (hereinafter referred to as "tobacco cartridge").

[0175] In the present specification, "tobacco leaf" is a general term for tobacco leaf after harvesting before curing treatment. One aspect of curing includes curing.

[0176] Meanwhile, tobacco leaf that has been cured and has not yet been processed into various modes (such as cut tobacco, tobacco sheet, or tobacco granules) for use in a tobacco product is referred to as "cured tobacco leaf". Furthermore, cured tobacco leaf that has been processed into various forms for use in a tobacco product is referred to as "processed tobacco leaf".

[0177] The cured tobacco leaf is processed into various modes for use in a tobacco product to form processed tobacco leaf. Modes for use in a tobacco product can include, for example, "cut tobacco", which is cured tobacco leaf cut into a predetermined size. Other examples include "tobacco sheet" and "tobacco granules", which are obtained by shaping a composition containing cured tobacco leaf ground into a predetermined particle size (hereinafter referred to as "fine tobacco dust") into a specific shape. Note that the above-mentioned "fine tobacco dust" is also a mode of processed tobacco leaf.

[0178] The processed tobacco leaf is not limited to the above-mentioned "cut tobacco", "tobacco sheet", "tobacco granules", and "fine tobacco dust", and can include various processed modes of cured tobacco leaf.

[0179] Depending on whether the mode of the processed tobacco leaf is the above-mentioned cut tobacco, tobacco sheet, or tobacco granules, the aspect of the fillable object filled with the processed tobacco leaf differs.

[0180] Examples of tobacco filler include: tobacco filler including cut tobacco with which the fillable object is filled (hereinafter referred to as "first tobacco filler"), tobacco filler including tobacco sheet with which the fillable object is filled (hereinafter referred to as "second tobacco filler"), and tobacco filler including tobacco granules with which the fillable object is filled (hereinafter referred to as "third tobacco filler").

[0181] <Filter>

[0182] As long as the filter has the typical functions of a filter, there is no particular limitation on it, and for example, a tow comprising synthetic fibers (also referred to simply as "tow"), a tubular filter such as a center hole filter, or a material such as paper processed into a cylindrical shape can be used. Examples of typical functions of a filter include regulating the amount of air mixed when, for example, an aerosol is inhaled, diluting flavors, and reducing nicotine and tar, but the filter does not need to have all of these functions. In addition, in electrically heated tobacco products, which tend to produce less flavoring components than cigarette products and have a lower tobacco filler filling rate than cigarette products, an important function of the filter is to suppress the filtering function while preventing the tobacco filler from falling off.

[0183] Note that the filter may be produced by a manufacturing method well known in the relevant technical field, or may be a commercial product.

[0184] There is no particular limitation on the mode of the filter, and examples include a normal filter including a single filter segment and a multi-segment filter including a plurality of filter segments (such as a double filter and a triple filter).

[0185] There is no particular limitation on the shape of the filter, and a well-known shape may be employed; typically a cylindrical shape may be employed, and the following aspects may be employed.

[0186] Furthermore, the filter may be provided with a section (such as a cavity or a recess) whose circumferential cross-section is an empty space (ie, hollow).

[0187] The filter can be ventilated by well-known methods, such as by using a pre-perforated or breathable wrapper, or by laser perforating the wrapper and the tip overlap (if a filter overlap is present). The complete filter overlap for ventilation can also be inherently breathable, or can be provided with ventilation holes. In breathable products in which both the wrapper and the filter overlap are present, the ventilation section of the overlap is preferably aligned with the position of the ventilation section of the wrapper (e.g., plug wrap). Ventilation holes through the filter wrapper, through the filter overlap, or through both can be formed by laser drilling during the filter manufacturing process.

[0188] <Tube>

[0189] The tube (ie, the cooling section) may be an aspect comprising a cylindrical member. The cylindrical member may be, for example, a paper tube obtained by processing paperboard into a cylindrical shape.

[0190] The internal structure of the cooling section preferably has a large total surface area. Accordingly, in a preferred embodiment, the cooling section can be formed from a sheet of thin material that is rolled and then pleated, gathered, and folded to form the channels. The more folds or wrinkles there are within a given element volume, the greater the total surface area of ​​the cooling section.

[0191] The cylindrical member is provided with perforations.

[0192] Having perforations allows external air to be introduced into the cooling section during inhalation. The vaporized components of the aerosol produced by heating the tobacco-containing section thereby come into contact with the external air, drop in temperature, and thereby liquefy to form the aerosol.

[0193] Although not particularly limited thereto, the diameter of the perforations (or the length across the perforations) may be, for example, 0.5-1.5 mm.

[0194] There is no particular limitation on the number of perforations, and it can be one, two or more perforations. For example, a plurality of perforations can be provided on the circumference of the cooling section.

[0195] In some embodiments, when the aerosol passes through the cooling section and is inhaled by the user, the temperature of the generated aerosol can be reduced by 10° C. or more. In some embodiments, in another aspect, when the aerosol passes through the cooling section and is inhaled by the user, the temperature of the generated aerosol can be reduced by 15° C. or more, and in yet another aspect, can be reduced by 20° C. or more.

[0196] The cooling section may comprise a sheet material selected from the group consisting of metal foil, polymer sheet, and substantially non-porous paper or paperboard. In one embodiment, the cooling section may comprise a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil.

[0197] The cooling section may be formed from a biodegradable material, for example a biodegradable polymer such as non-perforated paper or polylactic acid or starch copolymers.

[0198] The airflow through the interior of the cooling section preferably does not deflect significantly between adjacent sections. In other words, the airflow through the interior of the cooling section preferably flows along the longitudinal section without significant radial deflection. In some embodiments, the cooling section is formed of a material with low porosity or little porosity, except for the longitudinally extending channels. The material used to define or form the longitudinally extending channels (e.g., a rolled or gathered sheet) has low porosity or little porosity.

[0199] As described above, the cooling section may comprise a sheet of a suitable composition material that is curled, pleated, gathered, or folded. The cross-sectional profile of such elements may exhibit randomly oriented channels. The cooling section may be formed by other means. For example, the cooling section may be formed by a bundle of longitudinally extending tubes. The cooling section may be formed by extrusion, molding, lamination, injection, or chopping.

[0200] The cooling section can be formed by wrapping a pleated, gathered or folded sheet material with cigarette paper, for example. In some embodiments, the cooling section is gathered into a rod shape and can include a wrapper (for example a filter paper sheet of crimped material defined by cigarette paper).

[0201] <Cigarette Paper>

[0202] There are no specific restrictions on the composition of cigarette paper, and typical aspects thereof may be employed, having, for example, pulp as the primary component. The pulp may be made from wood pulp, such as softwood pulp and / or deciduous wood pulp, or may be produced from a mixture of non-wood pulps typically used for cigarette paper for smoking products, such as flax pulp, sisal pulp, or esparto grass. A single type of such pulp may be used, or a combination of multiple types of pulp may be used in any desired proportions.

[0203] The cigarette paper may also comprise a single sheet or may comprise a plurality of sheets.

[0204] In one aspect, paper can be used to wrap tobacco material (eg, cut tobacco).

[0205] Pulp types that can be used include chemical pulp, ground pulp, chemical ground pulp and thermomechanical pulp, which are obtained, for example, by kraft cooking, acid / neutral / alkaline sulfite cooking or soda cooking.

[0206] Note that the cigarette paper may be manufactured by the manufacturing method described below, or may be a commercially available product.

[0207] There is no particular limitation on the manufacturing method of the cigarette paper, the method may be a known method, and the cigarette paper may be manufactured, for example, from pulp beaten in a papermaking machine to achieve uniformity by adjusting the texture.

[0208] There is no particular limitation on the type of paper machine, and for example, a Fourdrinier paper machine, a cylinder paper machine, or a combined cylinder-short wire paper machine can be used.

[0209] In addition, wet strength agents can be added to impart water resistance to cigarette paper as needed, and sizing agents can be added to adjust the printing quality on cigarette paper. Internal additives used in papermaking, such as aluminum sulfate and various anionic, cationic, nonionic, or amphoteric yield improvers, drainage improvers, and paper strengthening agents, as well as papermaking additives such as dyes, pH adjusters, defoamers, pitch control agents, and slime control agents, can also be added.

[0210] The cigarette paper produced as described above may also undergo calendering, in which calender rollers are used to compress the cigarette paper. There are no specific limitations on the methods and conditions for the calendering process, which can be performed, for example, using the methods and conditions described in WO 2008 / 072523. Since the cigarette paper is pulped during the calendering process, the degree of pulping of the cigarette paper may be increased, and air permeability may be reduced.

[0211] <Tipping Paper>

[0212] Tipping paper refers to the paper used to connect two or more of the tobacco rod, cooling section, and filter section. Cigarette paper, on the other hand, is the paper used to wrap the various components that make up the tobacco rod, cooling section, or filter section. For example, if the filter section includes a centerhole filter and an acetate filter, both the paper wrapped around the centerhole filter and the paper wrapped around the acetate filter are considered cigarette paper. The filter is typically placed on one side of the mouth, so the tipping paper used to wrap the filter is necessarily the part that comes into contact with the mouth.

[0213] There is no particular limitation regarding the composition of the tipping paper, and typical aspects thereof may be adopted, such as tipping paper composed similarly to the above-mentioned cigarette paper.

[0214] <Blocking parts>

[0215] The blocking piece is for example used to prevent the matrix forming the aerosol from being released from the tobacco rod during the transportation etc. of the heat-not-burn smoking article. In this case, the front blocking piece (that is, the cap member) is arranged at the distal end of the tobacco rod.

[0216] The closure member may comprise a sheet. The closure member may also comprise a wrapper filled with the sheet, or may be formed, for example, by bonding sheets together without a wrapper. The former is preferred in terms of ease of manufacture.

[0217] The axial length of the obturator is preferably 6-20 mm, more preferably 6-10 mm. The circumference (i.e. the perimeter) thereof can be 15-30 mm. An axial length in this range enables mass production of the obturator. If the axial length is less than the lower limit, the device can also malfunction in such a way that components evaporated from the flavour source filler are not captured and leak to the outside, causing the device to become dirty. If the axial length is too long, the ventilation resistance of the obturator itself increases, and thus the ventilation resistance of the entire heat-not-burn smoking article increases, making it difficult to inhale during use.

[0218] In addition to the upstream end of the tobacco rod, an obturator can also be arranged at the downstream end of the tobacco rod. When incorporated as a tobacco rod, the axial direction of the obturator is a direction parallel to the longitudinal direction (i.e. the axial direction) of the tobacco rod. Arranging an obturator additionally at the downstream end of the tobacco rod can prevent the flavour source filler from spilling towards the mouthpiece segment during transport. In the case of the internal heating type, it can also prevent the flavour source filler from spilling towards the mouthpiece segment when the heater is inserted into the rod.

[0219] <LIQUID>

[0220] Liquid means a liquid composition for use in an electronic cigarette. In an electronic cigarette, the liquid is vaporized to generate an aerosol. The liquid can contain propylene glycol (PG), glycerol (GL), nicotine, and a flavourant.

[0221] <WRAPPER>

[0222] Any well-known wrap material that can encapsulate the filler, is not water-soluble, and is permeable to liquid (water, saliva, etc.) and water-soluble components of the filler can be used without limitation, and for example, a nonwoven fabric wrap material can be used. The material used for the wrap material includes, for example, a nonwoven fabric based on cellulose, and a commercially available nonwoven fabric can be used. The wrap material product can be produced by shaping a sheet containing such a material into a bag shape, and filling and sealing the bag shape with the filler by means such as heat sealing.

[0223] Although there is no particular limitation thereto, the basis weight of the above-mentioned sheet is typically 12-54 gsm, and preferably 24-30 gsm. Although there is no particular limitation thereto, the thickness of the sheet is typically 100-300 pm, and preferably 175-215 pm.

[0224] The inner surface and / or the outer surface of the wrap material can be partially coated with a water-repellent material. A water-repellent fluororesin is suitable as the water-repellent material. A specific example of this type of water-repellent fluororesin is Asahi Guard® manufactured by Asahi Glass Co., Ltd. The water-repellent fluororesin can be applied to the inner surface and / or the outer surface of the wrap material by a method such as spraying, dipping, or coating. For example, water-repellent fluororesins are applied to packaging materials for foods and other products containing lipids, such as candies, dairy products, prepared foods, fast food, and pet food. Therefore, this type of water-repellent fluororesin is safe even when applied to packaging materials to be placed in the oral cavity. Water-repellent materials are not limited to fluororesins and may be materials with a water-repellent effect, such as paraffin resins, silicone resins, or epoxy resins.

[0225] (Mode of Components of Smoking Articles)

[0226] Although not particularly limited thereto, the mode of the constituent member of the smoking article may be a nonwoven fabric.

[0227] <Nicotine Source>

[0228] Although not particularly limited thereto, the component parts of the smoking article may contain or consist of a nicotine source.

[0229] Although not particularly limited thereto, the nicotine source may contain or consist of nicotine or a salt thereof, and the nicotine or salt thereof may be derived from a tobacco raw material, a non-tobacco raw material, or a mixture thereof. Of these, nicotine or a salt thereof derived from a tobacco raw material is preferred. By using nicotine or a salt thereof derived from a tobacco raw material, the unique flavor of tobacco is inhaled simultaneously with the nicotine, resulting in a more satisfying smoking experience.

[0230] There are no specific restrictions regarding the content of the nicotine source relative to the constituent components of the entire smoking article.

[0231] The above-mentioned tobacco leaves, aged tobacco leaves, processed tobacco leaves, or a combination of two or more of these can be used as the tobacco-derived raw material for the nicotine source.

[0232] Examples of non-tobacco-derived raw materials used as nicotine sources include coffee and tea. The plant parts used may also include roots (including scaly roots (i.e., scaly bulbs), tuberous roots (i.e., potatoes), and bulbs), stems, tubers, bark (including the bark of stems and trunks), leaves, flowers (including petals, pistils, and stamens), seeds, nuts, or trunks or branches.

[0233] <Method for producing a flavored product>

[0234] In some embodiments of the present invention, the flavoring composition is obtained by flavoring a tobacco filler with a flavoring composition containing the above-mentioned methyl menthol derivative or its salt, in which the raw material derived from tobacco is formed into the following aspects: such as thin sheet tobacco or cut tobacco, or a filter, kraft paper, tube, cigarette paper, sealing member, packaging material or liquid.

[0235] 2. Smoking products

[0236] The smoking article of the present invention comprises the constituent components of the flavoring treatment described above in 1.

[0237] One, two or more flavoring component flavoring components may be included in the smoking article, with no particular limitation as to their number.

[0238] In addition to the components flavored with flavoring ingredients, the smoking article may include or not include components that are not flavored with flavoring ingredients. The components that are not flavored with flavoring ingredients may be the above-mentioned tobacco filler, filter, tube, cigarette paper, tipping paper, closure, packaging material or liquid.

[0239] In the smoking articles of the present invention, the cooling agent (A) contained in the flavoring component can be retained at the location where it was originally added before and after storage. Therefore, the smoking articles of the present invention can exhibit excellent cooling intensity as originally intended before and after storage.

[0240] The smoking article may be a heat-based smoking article, a combustion-based smoking article, a smokeless smoking article, or an electronic cigarette.

[0241] Smoking products include flavored inhalation products that users inhale to enjoy the flavor, and smokeless tobacco (i.e., smokeless smoking products) that users directly insert into the nasal cavity or oral cavity to enjoy the flavor. Flavored inhalation products can be roughly divided into combustion-type smoking products (such as traditional cigarettes), electronic cigarettes, and heat-not-burn smoking products.

[0242] Smokeless smoking articles include, for example, articles that are inserted into the mouth, such as snus and nicotine pouches, as well as dry snuff and the like.

[0243] Well-known methods can be used to produce moist snuff. In this case, the flavoring component product is obtained by filling a packaging material using a raw material (such as a nonwoven fabric) using well-known methods. For example, moist snuff is obtained by filling the packaging material with a regulated amount of the flavoring component and sealing it by means such as heat sealing.

[0244] Although the packaging material may be used without any particular limitation, it is preferable to use a cellulose-based nonwoven fabric or the like.

[0245] Examples of combustible smoking articles include cigarettes, pipes, kiseru, cigars, and cigarillos.

[0246] Electronic cigarettes include, for example, open-system types, closed-system types, and cigarette-like types.

[0247] Heat-not-burn smoking products (i.e., heated smoking products) can be heated by a heating device separate from the product or by a heating device integrated with the product. In the former type of smoking products (i.e., separate type), the heat-not-burn smoking products and the heating device are collectively referred to as "heat-not-burn smoking systems." Figure 1 and Figure 2 Describe an example of a heat-not-light smoking system.

[0248] Figure 1 2 is a cross-sectional view of a heat-not-burn smoking article 20. Figure 1 As shown, the heat-not-ignite smoking article 20 (hereinafter referred to as "smoking article 20") has a cylindrical shape. The circumferential length of the smoking article 20 is preferably 16-27 mm, more preferably 20-26 mm, and even more preferably 21-25 mm. Although not particularly limited thereto, the total length (i.e., horizontal length) of the smoking article 20 is preferably 40-90 mm, more preferably 50-75 mm, and even more preferably 50-60 mm.

[0249] The smoking article 20 comprises a smoking segment 20A, a filter portion 20C constituting a mouthpiece, and a connecting portion 20B connecting these.

[0250] The smoking segment 20A is cylindrical, and its total length (i.e., axial length) is, for example, preferably 5-100 mm, more preferably 10-50 mm, and even more preferably 10-25 mm. Although not particularly limited thereto, the cross-sectional shape of the smoking segment 20A may be, for example, circular, elliptical, or polygonal.

[0251] The smoking segment 20A comprises a sheet of smoking composition or material derived therefrom 21 surrounded by a wrapper 22. Flavoring agents may be included in the sheet of smoking composition or material derived therefrom 21.

[0252] The filter portion 20C is cylindrical. The filter portion 20C has a rod-shaped first segment 25 composed of filling with cellulose acetate fibers and a rod-shaped second segment 26 similarly composed of filling with cellulose acetate fibers. The first segment 25 is located on the side of the smoking segment 20A. The first segment 25 may have a hollow portion. The second segment 26 is located on the mouthpiece side. The second segment 26 is solid. The first segment 25 includes a first filling layer 25a (of cellulose acetate fibers) and an inner sealing wrap 25b wrapped around the first filling layer 25a. The second segment 26 includes a second filling layer 26a (of cellulose acetate fibers) and an inner sealing wrap 26b wrapped around the second filling layer 26a. The first segment 25 and the second segment 26 are connected by an outer sealing wrap 27. For example, the outer sealing wrap 27 is bonded to the first segment 25 and the second segment 26 by a vinyl acetate emulsion adhesive.

[0253] For example, the length of the filter portion 20C can be 10-30 mm, for example, the length of the connecting portion 20B can be 10-30 mm, for example, the length of the first segment 25 can be 5-15 mm, and for example, the length of the second segment 26 can be 5-15 mm. These individual segment lengths are examples and can be modified as appropriate depending on, for example, the manufacturability, desired quality, and length of the smoking segment 20A.

[0254] For example, the first segment 25 (i.e., the center hole segment) includes a first filler layer 25a having one or more hollow portions and an inner blocking wrapper 25b covering the first filler layer 25a. The first segment 25 has a function of increasing the strength of the second segment 26. The first filler layer 25a of the first segment 25 is densely filled with, for example, cellulose acetate fibers. The cellulose acetate fibers are solidified by adding, for example, 6-20% by mass of a plasticizer containing triacetin to the mass of the cellulose acetate. The hollow portions of the first segment 25 can have, for example, an inner diameter of 0.5-2 mm.

[0255] The first filler layer 25a of the first segment 25 can be composed of, for example, a relatively high fiber packing density, or can have a fiber packing density similar to that of the second filler layer 26a of the second segment 26 described below. Thus, during inhalation, air or aerosol will only flow through the hollow portions, and there will be almost no air or aerosol flow through the first filler layer 25a. If, for example, it is desired to reduce the aerosol components to a small extent by filtration in the second segment 26, the second segment 26 can be shortened, for example, so that the first segment 25 can be lengthened by an equivalent amount.

[0256] Substitution of the shortened second segment 26 with the first segment 25 effectively increases aerosol delivery. Thus, the texture of the first filler layer 25a of the first segment 25 as a fiber packing layer is such that it does not cause user discomfort when touched from the outside during use.

[0257] The second segment 26 is composed of a second filler layer 26a and an inner blocking wrapper 26b covering the second filler layer 26a. The second segment 26 (filter segment) is filled with cellulose acetate fibers at a typical density and has typical aerosol filtration performance.

[0258] The filtration performance of the first segment 25 in filtering the aerosol (i.e., mainstream smoke) released from the smoking segment 20A can be different from that of the second segment 26. The first segment 25 and / or the second segment 26 can contain a flavoring agent. The structure of the filter portion 20C is arbitrary and can be a structure having a plurality of segments as described above, or can be composed of a single segment. The filter portion 20C can be composed of one segment. In this case, the filter portion 20C can be composed of a first segment or a second segment.

[0259] ​The connecting portion 20B is cylindrical. For example, the connecting portion 20B includes a paper tube 23 formed into a cylindrical shape using cardboard. The connecting portion 20B can be filled with a cooling member for cooling the aerosol. Examples of cooling members include polymer (e.g., polylactic acid) sheets that can be folded for filling. A support member can be additionally provided between the smoking section 20A and the connecting portion 20B to prevent the smoking section 20A from shifting. The support member can be made of a known material, such as a center hole filter in the first section 25.

[0260] The smoking segment 20A, the connecting portion 20B, and the filter portion 20C are integrally joined by a wrapper 28 cylindrically wrapped around their outer sides. On one side (inner side) of the wrapper 28, the entire surface or nearly the entire surface is coated with a vinyl acetate emulsion adhesive, except for the vicinity of the ventilation holes 24. After the smoking segment 20A, the connecting portion 20B, and the filter portion 20C are integrated by the wrapper 28, a plurality of ventilation holes 24 are formed on the exterior by a laser process.

[0261] The ventilation holes 24 include two or more through holes that pass through the connecting portion 20B in the thickness direction. These two or more through holes are formed so as to be arranged radially when viewed from an extension of the central axis of the smoking article 20. In the current embodiment, the ventilation holes 24 are provided in the connecting portion 20B, but may be provided in the filter portion 20C. In addition, in the current embodiment, these two or more through holes among the ventilation holes 24 are arranged in a single row at constant intervals and in a single ring, but may also be arranged in two rows at constant intervals in two rings, or one or two rows of ventilation holes 24 may be provided discontinuously or irregularly. When the user places the mouthpiece in their mouth and inhales, external air is entrained in the mainstream smoke through the ventilation holes 24. However, it is not necessary to provide the ventilation holes 24.

[0262] Figure 2 An example of a heat-not-light smoking system is shown. The heat-not-light smoking system in the figures comprises a heat-not-light smoking article 20 and a heating device 10 that externally heats a smoking segment 20A.

[0263] The heating device 10 includes a body 11, a heater 12, a metal tube 13, a battery cell 14, and a control unit 15. The body 11 has a cylindrical recess 16, and the heater 12 and metal tube 13 are positioned to accommodate the smoking segment 20A to be inserted therein. The heater 12 can be a heater using an electric resistor, and the battery cell 14 supplies power according to commands from the control unit 15, which controls the temperature so that the heater 12 provides heating. The heat emitted by the heater 12 is transferred to the smoking segment 20A containing the aerosol through the metal tube 13, which has high thermal conductivity. The accompanying drawings illustrate an aspect in which the heating device 10 heats the smoking segment 20A from the outside, but the smoking segment can also be heated from the inside. Although not particularly limited to this, the heating temperature provided by the heating device 10 is preferably 400°C or less, more preferably 150°C to 400°C, and even more preferably 200°C to 350°C. The heating temperature refers to the heater temperature of the heating device 10.

[0264] Reference below Figure 3-5 Another example of a heat-not-light smoking article is described.

[0265] Figure 3 is a perspective view showing an example of the exterior of a heat-not-light smoking article. Figure 4 is an exploded view illustrating an example of a heat-not-burn smoking article. The heat-not-burn smoking article 30 (hereinafter referred to as smoking article 30) is, for example, an electronic cigarette or atomizer that generates and delivers an aerosol to the user in response to inhalation. Note that a single, continuous inhalation by the user will be referred to as a "puff." The smoking article 30 also adds components, such as flavoring, to the generated aerosol and releases the flavoring into the user's mouth.

[0266] like Figure 3 and 4 As shown, smoking article 30 comprises body 30A, aerosol source holder 30B and additive component holder 30C. Main body 30A supplies electricity and controls the operation of whole device. Aerosol source holder 30B holds the aerosol source for atomization to produce aerosol. Additive component holder 30C holds tobacco filler 38. Tobacco filler 38 can comprise the component member (that is, the component member of flavoring component flavoring process) of carrying flavoring of the present invention, such as the cut tobacco of carrying flavoring, the thin sheet tobacco of carrying flavoring, the tobacco particles of carrying flavoring, the particle matrix of carrying flavoring or the metal foil of carrying flavoring. User holds mouthpiece in mouth and inhales the aerosol that has added flavoring etc. at the end on additive component holder 30C side.

[0267] For example, the user assembles the body 30A, the aerosol source holder 30B, and the additive component holder 30C to form the smoking article 30. The body 30A, the aerosol source holder 30B, and the additive component holder 30C are, for example, cylindrical or truncated cone-shaped with a diameter of a predetermined size, and the body 30A, the aerosol source holder 30B, and the additive component holder 30C can be joined together in that order. The body 30A and the aerosol source holder 30B are connected by, for example, a male thread segment and a female thread segment that are engaged at their respective ends. The aerosol source holder 30B and the additive component holder 30C are connected, for example, by assembling the additive component holder 30C, which has a tapered side, into a cylindrical portion provided at one end of the aerosol source holder 30B. The aerosol source holder 30B and the additive component holder 30C can also be disposable replacement parts.

[0268] Figure 5 3 is a schematic diagram showing an example of the interior of the smoking article 30. The body 30A includes a power supply 31, a control unit 32 and an inhalation sensor 33. The control unit 32 is electrically connected to the power supply 31 and the inhalation sensor 33, respectively. The power supply 31 is, for example, a secondary battery, and supplies power to the circuits included in the smoking article 30. The control unit 32 is a processor such as a microcontroller (i.e., a microcontroller unit (MCU)), and controls the operation of the circuits included in the smoking article 30. The inhalation sensor 33 is, for example, an atmospheric pressure sensor or a flow rate sensor. When a user inhales from the mouthpiece of the smoking article 30, the inhalation sensor 33 outputs a value corresponding to the negative pressure or gas flow rate generated inside the smoking article 30. That is, the control unit 32 can detect inhalation based on the output value of the inhalation sensor 33.

[0269] The aerosol source holder 30B of the smoking article 30 includes a storage member 34, a supply unit 35, a load 36, and a residual quantity sensor 37. The storage member 34 is a container for storing a liquid aerosol source to be atomized by heating. It should be noted that the aerosol source is a polyol material such as glycerin or propylene glycol. It should be noted that the aerosol source can also be a mixed solution containing nicotine liquid, water, flavorings, etc. This aerosol source is pre-stored in the storage member 34. It should be noted that the aerosol source can also be a solid, not requiring the storage member 34.

[0270] The supply unit 35 includes a wick formed of, for example, twisted fiber material such as glass fiber. The supply unit 35 is connected to the storage 34. The supply unit 35 is connected to the load 36, or at least a portion of the supply unit 35 is disposed in the vicinity of the load 36. The aerosol source penetrates the wick by capillary action and moves to a portion in which the aerosol source can be atomized by heating by the load 36. In other words, the supply unit 35 extracts the aerosol source from the storage 34 and transports it to the load 36 or in the vicinity thereof. Instead of the glass fiber used for the wick, a porous ceramic can be used.

[0271] The load 36 is, for example, a coil-shaped heater and generates heat when a current flows. In addition, the load 36 has a positive temperature coefficient (PTC) characteristic and the electric resistance is almost directly proportional to the heating temperature thereof. Note that the load 36 does not necessarily have the positive temperature coefficient characteristic and the electric resistance can be correlated to the heating temperature. As an example, the load 36 can have a negative temperature coefficient (NTC) characteristic. Note that the load 36 can be wound on the outside of the wick, or conversely can be configured so that the wick covers the circumference of the load 36. The power supply to the load 36 is controlled by the control unit 32. When the supply unit 35 supplies the aerosol source from the storage 34 to the load 36, the aerosol source is evaporated by the heat of the load 36 and thus an aerosol is generated. When the inhalation activity of the user is detected based on the output value of the inhalation sensor 33, the control unit 32 supplies power to the load 36 to generate an aerosol. In addition, when the remaining amount of the aerosol source stored in the storage 34 is sufficient, a sufficient amount of the aerosol source is also supplied to the load 36, and since the heat generated at the load 36 is transferred to the aerosol source, that is, since the heat generated at the load 36 is used for the temperature rise and vaporization of the aerosol source, the temperature of the load 36 almost never exceeds a planned, predetermined temperature. On the other hand, when the aerosol source stored in the storage 34 is depleted, the amount of the aerosol source supplied to the load 36 per hour decreases. Therefore, since the heat generated at the load 36 is not delivered to the aerosol source, that is, since the heat generated at the load 36 is not used for the temperature rise and vaporization of the aerosol source, the load 36 overheats, and the electric resistance of the load 36 accordingly increases.

[0272] The residual amount sensor 37 outputs sensing data for estimating the residual amount of the aerosol source stored in the storage 34 based on the temperature of the load 36. For example, the residual amount sensor 37 includes a current measuring resistor (i.e., a shunt resistor) connected in series to the load 36, and a measuring device connected in parallel to the resistor and measuring the voltage level of the resistor. Note that the electric resistance of the resistor is a planned, predetermined value that hardly changes with temperature. Therefore, the level of the current flowing to the resistor is determined based on the known electric resistance and the measured voltage.

[0273] The additive component holder 30C of the smoking article 30 holds the tobacco filler 38 inside it. As mentioned above, the tobacco filler 38 can include the component of the flavoring agent of the present invention (that is, the component of the flavoring component flavoring process), such as the cut tobacco of the flavoring agent, the thin tobacco of the flavoring agent, the tobacco particles of the flavoring agent, the particle matrix of the flavoring agent or the metal foil of the flavoring agent. In addition to the "component of the flavoring agent of the present invention", the tobacco filler 38 can also include ordinary tobacco filler. Ordinary tobacco filler can include cut tobacco and / or thin tobacco (that is, thin tobacco cuttings) cut into a predetermined width. The additive component holder 30C has ventilation holes on the mouthpiece side and in the portion coupled to the aerosol source holder 30B, so that when the user inhales from the mouthpiece, negative pressure is generated in the additive component holder 30C, the aerosol generated in the aerosol source holder 30B is inhaled, and components such as nicotine and flavoring agents are added to the aerosol in the additive component holder 30C and released into the user's oral cavity.

[0274] Examples

[0275] The present invention is experimentally described by the following examples, and it is not intended that the scope of the present invention be construed as being limited to the examples.

[0276] <Retention Index (RI) Measurement by GC / MS>

[0277] Menthol (L-menthol, manufactured by Takasago International Co., Ltd.) and cooling agent (the above 370, 5. 10. 20. WS-5, and WS-23) were diluted by adding ethanol to obtain diluted solutions of menthol and each cooling agent diluted to 1000 ppm in ethanol.

Figure 6 The results in 370 is the most difficult to evaporate among the menthol and cooling agents measured at this time.

[0314] <Sensory Evaluation>

[0315] (Preparation of Heat-Not-Ignite Smoking Articles (Example 1, Comparative Examples 1 and 2))

[0316] Tobacco rods made of tobacco leaves (glycerol content relative to tobacco filler: 7.5 wt %) were prepared based on a well-known papermaking method.

[0317] In addition, 20 g of a methyl menthol derivative (N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide, 370, manufactured by Takasago International Co., Ltd.), 80 g of menthol (manufactured by Takasago International Co., Ltd.) as a cooling flavor component, or 20 g of 2-isopropyl-N,2,3-trimethylbutanamide ( WS-23, manufactured by Symrise Inc.) were each added to 80 g of ethanol and mixed therewith to obtain a methyl menthol derivative solution, a menthol solution, and a solution of a cooling agent other than the methyl menthol derivative, respectively.

[0318] The above-mentioned methyl menthol derivative solution, menthol solution or solution of a cooling agent other than the methyl menthol derivative was then added using a syringe so as to spread throughout the entire tobacco filler in the prepared tobacco rod, thereby obtaining the tobacco rod containing a cooling component of Example 1, wherein the content of the methyl menthol derivative was 2,000 ppm relative to the tobacco filler flavored with flavoring ingredients (i.e., the sum of the tobacco filler and the flavoring ingredients); the tobacco rod containing a cooling component of Comparative Example 1, wherein the content of menthol was 5,000 ppm relative to the tobacco filler flavored with flavoring ingredients; and the tobacco rod containing a cooling component of Comparative Example 2, wherein the content of the cooling agent other than the methyl menthol derivative was 2,000 ppm relative to the tobacco filler flavored with flavoring ingredients.

[0319] (Preparation of Heat-Not-Ignite Smoking Article (Example 2))

[0320] By mixing 0.5 g of methyl menthol derivative (the above A flavoring component containing a carrier (hydroxypropyl cellulose) was obtained by injecting 10.8 mg of the flavoring component thus obtained into 260 mg of tobacco filler (containing tobacco leaves), wherein the content of the methyl menthol derivative was 2,000 ppm relative to the tobacco filler flavored with the flavoring component (i.e., the sum of the tobacco filler and the flavoring component). The component contents of the thus obtained heat-type smoking article containing the cooling component of Example 2 were: 96.0% by mass of tobacco leaves, 0.2% by mass of the methyl menthol derivative, 0.6% by mass of hydroxypropyl cellulose, and 3.2% by mass of propylene glycol.

[0321] (Preparation of Combustion-Type Smoking Articles (Example 3, Comparative Examples 3 and 4))

[0322] Combustion smoking articles made from tobacco leaves are prepared.

[0323] A solution of a methyl menthol derivative, a solution of menthol, and a solution of a cooling agent other than a methyl menthol derivative were obtained by similar procedures, respectively, and using menthol or other cooling agents similar to the cooling agents in the preparation of the above-mentioned heat-not-light smoking articles (Example 1, and Comparative Examples 1 and 2).

[0324] The above-mentioned methyl menthol derivative solution, menthol solution or solution of a cooling agent other than the methyl menthol derivative is then added using a syringe so that it spreads throughout the entire tobacco filler in the prepared combustion-type smoking article, thereby obtaining the combustion-type smoking article containing a cooling component of Example 3, wherein the content of the methyl menthol derivative is 2,000 ppm relative to the tobacco filler flavored with flavoring ingredients (i.e., the sum of the tobacco filler and the flavoring ingredients); the combustion-type smoking article containing a cooling component of Comparative Example 3, wherein the content of menthol is 5,000 ppm relative to the tobacco filler flavored with flavoring ingredients; and the combustion-type smoking article containing a cooling component of Example 4, wherein the content of a cooling agent other than the methyl menthol derivative is 2,000 ppm relative to the tobacco filler flavored with flavoring ingredients.

[0325] The inventors conducted preliminary studies and found that because menthol has a weaker cooling intensity than the aforementioned methyl menthol derivatives and cooling agents other than methyl menthol derivatives, it is difficult to compare their cooling intensity at similar content. While the content of the methyl menthol derivatives or cooling agents other than methyl menthol derivatives as cooling ingredients in Examples 1-3 and Comparative Examples 2 and 4 was 2000 ppm, the content of menthol as a cooling ingredient in Comparative Examples 1 and 3 was set to 5,000 ppm. This was done to adjust the cooling intensity as much as possible to facilitate comparison and to evaluate the cooling intensity in this sensory evaluation.

[0326] (Preparation of smoking articles before storage)

[0327] The heat-not-light smoking articles of Examples 1 and 2 and Comparative Examples 1 and 2 produced as described above (within 5 days after manufacture, at 25° C.; hereinafter referred to as “heat-not-light smoking articles before storage”) were placed in a Figure 2 In the non-combustion smoking system with external heating shown in FIG. Combustion smoking articles of Example 3 and Comparative Examples 3 and 4, which had been produced as described above, were also prepared (within 5 days of manufacture, at 25° C.; hereinafter referred to as “heat-not-light smoking articles before storage”). Each smoking article thus prepared was used to conduct the following sensory evaluation.

[0328] (1) Cooling intensity

[0329] Five trained panelists evaluated the cooling sensation associated with each of the heat-not-light smoking articles before storage in Examples 1 and 2 and Comparative Examples 1 and 2, and each of the combustion smoking articles before storage in Example 3 and Comparative Examples 3 and 4. In this specification, "cooling sensation" means a refreshing sensation (or a feeling of freshness) and / or a cooling sensation (or a feeling of coolness).

[0330] The panelists evaluated the cool sensation of the smoking test paper according to the six-level scale in Table 1 below. In the scale shown in Table 1 below, a score of 3 is equal to the score of the smoking article containing menthol (Comparative Example 1 for heat-not-ignite smoking articles and Comparative Example 3 for combustion-type smoking articles). The evaluators all recognized in advance that when evaluating Examples 1 and 2 and Comparative Example 2, Comparative Example 1 would score 3 in Table 1, and when evaluating Example 3 and Comparative Example 4, Comparative Example 3 would score 3 in Table 1. The evaluation results were obtained by calculating the average value of the five panelists, and when the average value was two decimal places, the calculated scores were rounded to the nearest tenth. The evaluation results are shown in Table 2.

[0331] Table 1

[0332]

[0333] Table 2

[0334]

[0335] As shown above, the menthol content (Comparative Examples 1 and 3) was 5,000 ppm, while the methyl menthol derivative content (Examples 1-3) and the cooling agent content other than the methyl menthol derivative (Comparative Examples 2 and 4) were adjusted to 2,000 ppm to facilitate comparison of cooling intensity in this evaluation.

[0336] From the results in Table 2, among the tobacco rods of the heat-not-ignite smoking articles (Example 1 and Comparative Examples 1 and 2), the cooling intensity of the smoking article containing the methyl menthol derivative (Example 1) is similar to the cooling intensity of the smoking article containing menthol (Comparative Example 1). Among the combustion-type smoking articles (Example 3 and Comparative Examples 3 and 4), the cooling intensity of the smoking article containing the methyl menthol derivative (Example 3) is greater than the cooling intensity of the smoking article containing menthol (Comparative Example 3).

[0337] Therefore, when the menthol content is reduced to 2000 ppm, the cooling sensation intensity seems to be insufficient, similar to the methyl menthol derivative. Therefore, it is found that the smoking article containing the methyl menthol derivative has a greater cooling sensation intensity than the smoking article containing menthol.

[0338] It was also found that the smoking article containing the methyl menthol derivative (Example 1 or Example 3) had a cooling sensation intensity that was equal to or greater than the cooling sensation intensity of the smoking article containing a cooling agent other than the methyl menthol derivative (Comparative Example 2 or 4), regardless of whether it was a combustion smoking article or a heat-not-ignite smoking article.

[0339] The smoking article containing methyl menthol derivatives with the added carrier hydroxypropyl cellulose (Example 2) also has a cooling intensity that is roughly equal to the cooling intensity of the smoking article containing methyl menthol derivatives without the addition of hydroxypropyl cellulose (Example 1). This confirms that the characteristics of the smoking article containing methyl menthol derivatives confirmed from the above sensory evaluation results are expressed regardless of the presence or absence of additional hydroxypropyl cellulose. The carrier has the characteristics of stabilizing and covering the flavorings and / or cooling components dispersed in the flavoring ingredients. Therefore, in addition to suppressing the evaporation and dissipation of flavorings and / or cooling components and improving storage resistance, it can be expected that adding the above carrier has the effect of protecting flavorings and / or cooling components from physical damage.

[0340] (2) Bitter taste

[0341] Five trained panelists evaluated the bitterness of the heat-not-ignite smoking articles of Examples 1 and 2 and Comparative Examples 1 and 2, and the combustion smoking articles of Example 3 and Comparative Examples 3 and 4, prepared as described above, before storage. It is known that increasing the amount of the cooling component to achieve the desired cooling intensity imparts both a cooling sensation and a bitter taste. Therefore, the bitterness of the cooling component is preferably weak.

[0342] The panelists evaluated the cool sensation associated with each smoking test roll according to the four-level scale in Table 3 below. In the scale used in Table 3 below, a score of 2 is equivalent to the score of the smoking article containing menthol (for heat-not-ignite smoking articles, it is Comparative Example 1 and for combustion-type smoking articles, it is Comparative Example 3). The evaluators all recognized in advance that, in the smoking article, when evaluating Examples 1 and 2 and Comparative Example 2, Comparative Example 1 would score 2 in Table 3, and when evaluating Example 3 and Comparative Example 4, Comparative Example 3 would score 2 in Table 3. The evaluation results were obtained by calculating the average value of the five panelists, and when the average value had the second decimal place, the second decimal place was rounded to the nearest tenth. The evaluation results are shown in Table 4.

[0343] Table 3

[0344]

[0345] Table 4

[0346]

[0347] In view of the results in Table 4, it was found that the smoking article containing the methyl menthol derivative (Example 1 or Example 3) and the smoking article containing a cooling agent other than the methyl menthol derivative (Comparative Example 2 or 4) had a weaker bitter taste than the smoking article containing menthol (Comparative Example 1 or Comparative Example 3), regardless of whether it was a combustion smoking article or a heat-not-light smoking article, and therefore were preferred.

[0348] The same results as in Example 1 (without the addition of hydroxypropyl cellulose) were also achieved using a smoking article containing a methyl menthol derivative to which the carrier hydroxypropyl cellulose had been added (Example 2). This confirms that the preferred characteristic of the methyl menthol derivative, which is a mild bitter taste, as demonstrated by the sensory evaluation results above, was achieved regardless of the presence or absence of additional hydroxypropyl cellulose. As shown above, in addition to suppressing the evaporation and dissipation of the flavoring and / or cooling component and improving storage stability, it is expected that the carrier described above has the effect of protecting the flavoring and / or cooling component from physical damage.

[0349] (3) Cooling sensation (regional effect)

[0350] Five trained panelists evaluated the cooling site effects of the heat-not-ignite smoking articles of Examples 1 and 2 and Comparative Examples 1 and 2, and the combustion smoking articles of Example 3 and Comparative Examples 3 and 4, prepared as described above, before storage. The five panelists selected multiple sites on the upper jaw, tongue, cheek, and throat as the oral sites where a cooling sensation was felt when evaluating each Example and Comparative Example, and the effects on the sites (site effects) were evaluated. The aggregated results are shown in Table 5. For example, a score of "5" in Table 5 means that all five panelists experienced a cooling sensation at a specific site.

[0351] Table 5

[0352]

[0353] As shown in Table 5, fewer evaluators reported feeling a cooling sensation on the tongue when using smoking articles containing a methyl menthol derivative (Example 1 or Example 3) or smoking articles containing a cooling agent other than a methyl menthol derivative (Comparative Example 2 or Comparative Example 4) than when using smoking articles containing menthol (Comparative Example 1 or Comparative Example 3), regardless of whether they were combustion smoking articles or heat-not-ignite smoking articles.

[0354] The above evaluation results on the bitter taste imparted to the tongue suggest that this may be related to the difference in the site where the cooling sensation is felt. In other words, when the tongue is less likely to feel the cooling sensation, the bitter taste is considered to be reduced.

[0355] In addition to the aforementioned multiple-choice evaluation of the site effect, participants were also asked to select only one site in the mouth where they felt the most cooling sensation, from the roof of the mouth, tongue, cheek, and throat. The total results are shown in Table 6.

[0356] Table 6

[0357]

[0358] As shown in Table 6, compared to smoking articles containing menthol (Comparative Example 1 or Comparative Example 3) or smoking articles containing a cooling agent other than a methyl menthol derivative (Comparative Example 2 or Comparative Example 4), more evaluators experienced the greatest cooling sensation in the throat when using the smoking article containing a methyl menthol derivative (Example 1 or Example 3), regardless of whether it was a combustion smoking article or a heat-not-ignite smoking article. Using a cooling agent has a distinct characteristic, namely, a cooling sensation in the throat that allows smokers to experience an unprecedented cooling sensation.

[0359] Similar to Example 1, in which no hydroxypropyl cellulose was added, more evaluators reported experiencing the greatest cooling sensation in the throat when using the smoking article containing the methyl menthol derivative (Example 2) with the carrier hydroxypropyl cellulose added. This confirms that the cooling sensation characteristic of the methyl menthol derivative, as demonstrated by the sensory evaluation results, was achieved regardless of the presence or absence of the additional hydroxypropyl cellulose. As shown above, in addition to suppressing the evaporation and dissipation of the flavoring and / or cooling component and improving shelf stability, the carrier is expected to protect the flavoring and / or cooling component from physical damage.

[0360] (4) Storage stability

[0361] The heat-not-burn smoking articles of Examples 1 and 2 and Comparative Examples 1 and 2 prepared as described above were exposed to air and stored at 30°C for 5 days. Each heat-not-burn smoking article after storage was then mounted on a Figure 2 The non-combustion smoking system with external heating is shown.

[0362] Pre-storage combustion smoking articles of Example 3 and Comparative Examples 3 and 4 were also prepared as described above and stored exposed to air at 30°C for 5 days.

[0363] Ordinary products are stored in, for example, a polypropylene film under almost sealed conditions to suppress evaporation of menthol, etc. On the other hand, the above-mentioned storage at 30° C. exposed to air can be regarded as a relatively severe storage condition.

[0364] Based on the procedure and evaluation criteria described above in "(1) Cooling Sensation Intensity," the cooling sensation imparted by the smoking articles thus prepared was evaluated after storage. The evaluation results are shown in Table 7. The "After Storage" column in Table 7 shows the evaluation results of the smoking articles after storage. At the same time, the "Before Storage" column in Table 7 shows the evaluation results of the smoking articles before storage from Table 2.

[0365] Table 7

[0366] Before storage After storage Heat-not-burn smoking products Example 1 3.0 4.0 Example 2 2.8 3.4 Comparative Example 1 3.0 1.6 Comparative Example 2 2.6 1.8 Combustion smoking products Example 3 3.6 3.8 Comparative Example 3 3.0 1.6 Comparative Example 4 2.8 2.0

[0367] As shown in Table 7, compared to the cooling intensity before storage, the smoking articles containing menthol (Comparative Examples 1 and 3) and the smoking articles containing a cooling agent other than a methyl menthol derivative (Comparative Examples 2 and 4) had a reduced cooling intensity after storage, regardless of whether they were combustion-type smoking articles or heat-not-ignite smoking articles. At the same time, the cooling intensity of the smoking articles containing a methyl menthol derivative (Example 1 and Comparative Example 3) after storage was equal to or greater than the cooling intensity before storage.

[0368] Similar to Example 1 in which no hydroxypropyl cellulose was added, the cooling intensity of the smoking article containing the methyl menthol derivative (Example 2) to which the carrier hydroxypropyl cellulose had been added after storage was equal to or greater than the cooling intensity before storage. This confirms that, regardless of the presence or absence of additional hydroxypropyl cellulose, the characteristic of the cooling intensity of the smoking article containing the methyl menthol derivative after storage, as confirmed by the above sensory evaluation results, was equal to or greater than the cooling intensity before storage. As indicated above, in addition to suppressing the evaporation and dissipation of flavorings and / or cooling components and improving storage resistance, it can be expected that the above carrier has the effect of protecting flavorings and / or cooling components from physical damage.

[0369] Without being overly theoretical, it can be speculated that the reason why smoking articles containing methyl menthol derivatives have a cooling sensation intensity after storage that is at least equal to the cooling sensation intensity before storage is hypothesized to be as follows. It is speculated that the moisture contained in the tobacco and volatile components derived from the tobacco evaporate and decrease during storage, while the methyl menthol derivative remains unevaporated. Therefore, it can be inferred that the cooling sensation of the methyl menthol derivative is generally more easily perceived.

[0371] (1) Measuring menthol and other cooling agents in tobacco fillers in an open system

[0372] By adding ethanol to dissolve menthol and other cooling agents (the above 370 and The solutions were prepared using a microsyringe (MS-50, Ito microsyringe, manufactured by Ito Seisakusho) to prepare the solutions. Each of the solutions thus obtained was added to the tobacco filler portion of a combustion-type smoking article using a microsyringe (MS-50, Ito microsyringe, manufactured by Ito Seisakusho) such that the content of menthol or other cooling agents was 5,000 ppm relative to the weight of the tobacco, and the samples were immediately considered as "cigarette samples before storage" after the addition. Each of the solutions thus obtained was also added to the tobacco filler portion of a heat-not-burn smoking article (a tobacco rod comprising a tobacco filler portion and a filter portion) using the microsyringe to such that the content of menthol or other cooling agents was 5,000 ppm relative to the weight of the tobacco therein, and the samples were immediately considered as "tobacco rod samples before storage" after the addition. The cigarettes and tobacco rods injected with menthol or other cooling agents were then placed on a tray (DT-1 disposable tray, manufactured by As One), stored in an incubator (SCI-13 compact incubator, manufactured by Shibata) set at 30°C for 5 days, and were respectively considered as "cigarette samples after storage" and "tobacco rod samples after storage".

[0373] In addition, 1.0 g of quinoline was accurately weighed as an internal standard and diluted to 1 L with methanol to be used as an extraction solvent.

[0374] The pre-storage cigarette samples, pre-storage tobacco rod samples, post-storage cigarette samples, and post-storage tobacco rod samples obtained as described above were then subjected to the following treatments.

[0375] The tobacco filler portion of each sample was removed and placed in a screw-threaded tube, and 10 mL of the extraction solvent prepared as described above was added. The screw-threaded tube was then shaken at 200 rpm for 20 minutes, and after standing overnight, again at 200 rpm for 20 minutes to obtain a tobacco filler portion extract sample. The extract samples obtained from the pre-storage cigarette sample, pre-storage tobacco rod sample, post-storage cigarette sample, and post-storage tobacco rod sample were referred to as the "pre-storage cigarette extract sample," the "pre-storage tobacco rod extract sample," the "post-storage cigarette extract sample," and the "post-storage tobacco rod extract sample," respectively.

[0376] The extract samples thus obtained were collected using syringes (25 mL, SS-02SZ, manufactured by Terumo Corporation), respectively, and filtered through filters (0.45 μm, Prem Syringe Filter, RC, manufactured by Agilent Technologies), and the liquids obtained after filtration were respectively regarded as extract samples for cigarette analysis before storage, extract samples for tobacco rod analysis before storage, extract samples for cigarette analysis after storage, and extract samples for tobacco rod analysis after storage.

[0377] Select the target ions and qualifier ions shown below for the corresponding cooling agents. Also select the target ion and qualifier ion for quinoline, which is used as an internal standard.

[0400] The ratio of the internal standard to menthol or other cooling agent (ie, internal standard ratio) was calculated by the following equation using the area of ​​menthol or other cooling agent and the area of ​​the internal standard from the chromatogram obtained for each analyzed extract sample.

[0401] Internal standard ratio = menthol or other cooling agent area / internal standard area

[0402] Using the internal standard ratio thus obtained, the residual rate of menthol and each cooling agent added to the cigarette or tobacco rod was calculated to three significant figures based on the following equation. The results for cigarettes (i.e., combustion-type smoking articles) are shown in Table 8, and the results for tobacco rods (i.e., heat-not-ignite smoking articles) are shown in Table 9.

[0403] Residual rate = (internal standard ratio of menthol or other cooling agents in the extract sample analyzed after storage) / (internal standard ratio of menthol or other cooling agents in the extract sample analyzed before storage) x 100

[0406] Table 9

[0407]

[0408] In view of the results in Tables 8 and 9, it was found that menthol or cooling agents other than methyl menthol derivatives contained in tobacco ( WS-23) after storage than before storage, whether it is in a combustion-type smoking product or a heat-not-ignite smoking product. At the same time, it was found that the methyl menthol derivatives contained in tobacco (i.e., 370) remained almost unchanged before and after storage.

[0409] This indicates that smoking articles containing methyl menthol derivatives have better shelf stability than smoking articles containing menthol or smoking articles containing cooling agents other than methyl menthol derivatives, whether in combustion smoking articles or heat-not-light smoking articles.

[0410] (2) Measurement of menthol and other cooling agents in tobacco fillers and filters in closed systems

The solution thus obtained was added to the tobacco filler portion of an unheated smoking article (a tobacco rod comprising a tobacco filler portion and a filter portion) using the above-mentioned microsyringe so that the methyl menthol derivative content was 2,500 ppm, 5,000 ppm, or 10,000 ppm relative to the weight of the tobacco therein, and the sample immediately after the addition was considered a "tobacco rod sample before storage." Each tobacco rod injected with the methyl menthol derivative was placed in a Lami-Zip bag (AL-5, manufactured by Seisannipponsha) and placed in an incubator set at 30°C (SCI-13 compact incubator, manufactured by Shibata Co., Ltd.) for 5 days to provide a "tobacco rod sample after storage."

[0412] The pre-storage and post-storage tobacco rod samples obtained in the above-described manner were subjected to the following treatments.

[0413] The tobacco filler portion and filter portion were removed from each sample and placed in separate screw-threaded tubes, and 10 mL of methanol was added. The screw-threaded tubes were then shaken at 200 rpm for 20 minutes. After standing overnight, they were shaken again at 200 rpm for 20 minutes to obtain extract samples from the tobacco filler portion and the filter portion, respectively. The extract samples obtained from the pre-storage tobacco rod sample and the post-storage tobacco rod sample were respectively referred to as the "pre-storage tobacco rod extract sample" and the "post-storage tobacco rod extract sample."

[0414] The extract samples thus obtained were collected using syringes (25 mL, SS-02SZ, manufactured by Terumo Corporation), respectively, and filtered through filters (0.45 μm, Prem Syringe Filter, RC, manufactured by Agilent Technologies), and the liquids obtained after filtration were respectively regarded as extract samples for analysis (“extract sample for tobacco rod analysis before storage” and “extract sample for tobacco rod analysis after storage”, respectively).

[0415] The extract sample for analysis obtained as described above was then subjected to GC / MS analysis under the following conditions.

Figure 7-9In FIG, the upper part is the total ion chromatogram of the extract from the tobacco filler portion, and the lower part is the total ion chromatogram of the extract from the filter portion. The peaks of the methyl menthol derivatives are Figure 7 The retention time (RT) is 53.05, and Figure 8 and 9 Medium close RT: 53.07.

[0437] exist Figure 7-9 In the present invention, a peak derived from the methyl menthol derivative was detected in the extract from the tobacco filler portion, but no peak derived from the methyl menthol derivative was detected in the extract from the filter portion. Therefore, it was found that the methyl menthol derivative did not migrate from the tobacco filler portion to the filter portion immediately after addition (and before storage).

The peaks of the methyl menthol derivatives are Figure 10 Close RT: 53.00, in Figure 11 Close to RT: 53.03, and in Figure 12 Medium close RT: 53.06.

[0439] exist Figure 10-12 In the experiment, a peak derived from the methyl menthol derivative was detected in the extract from the tobacco filler portion, but no peak derived from the methyl menthol derivative was detected in the extract from the filter portion. Thus, it was found that, similar to before storage, the methyl menthol derivative did not migrate from the tobacco filler portion to the filter portion after storage.

[0440] This indicates that the methyl menthol derivative remains at the site to which it was originally added, and smoking articles containing the methyl menthol derivative can be expected to have the same cooling sensation intensity after storage as before storage.

[0441] Thus, it was found that the flavoring component of the present invention, which contains a cooling agent (A) and has a retention index (RI) of 1300 or higher, has a cooling intensity superior to that of menthol. It was also found that the flavoring component has a less bitter taste than menthol.

[0442] It was also found that the above flavoring ingredient aromatized component members have a storage stability superior to that of flavoring ingredient aromatized component members containing menthol or a cooling agent other than the above cooling agent (A).
