Description

Technical Field

[0001] This invention relates to flavored sheets including cooling blocks, filters, packaging paper, and aerosol-generating articles including the same. Background Technology

[0002] Currently, some cooling agents are used alone in shaving foam, toothpaste, mouthwash, and food, but cooling blocks containing flavored cooling agents have not yet replaced menthol in aerosol-generating products.

[0003] Compared to other flavoring agents, most current aerosol-generated products use menthol. Only those products possessing the key characteristics of menthol or exhibiting differentiation and diversity compared to existing menthol formulations can be competitive. Developing menthol alternatives and product application technologies is a pressing issue to address in order to achieve properties similar to menthol, maintain product competitiveness, and continue to provide convenience to consumers.

[0004] On the other hand, the sensory characteristics of menthol can be divided into primary and secondary characteristics. The primary characteristics include Cooling (cooling and mellow), Fresh (not drying and refreshing), and Minty (minty scent); the secondary characteristics include Herbal (herbal scent), Green (green grass scent), and Earthy (earthy scent), etc.

[0005] It is difficult to achieve the complex sensory properties of menthol by using certain specific cooling agents alone. Similar properties to menthol can only be reproduced by mixing the characteristics of different cooling agents, so it is necessary to develop relevant formulations. Summary of the Invention

[0022] The embodiments will now be described in detail with reference to the accompanying drawings. It should be understood that various modifications can be made to the embodiments, and the scope of this application is not limited to the embodiments described below. All modifications to the embodiments, their equivalents, and even their substitutes are within the scope of this invention.

[0023] The terminology used in the embodiments is for illustrative purposes only and is not intended to limit the scope. Unless otherwise specified in the content, singular expressions include plural meanings. In this specification, terms such as "comprising" or "having" are used to express the presence of the features, numbers, steps, actions, constituent elements, components, or combinations thereof described in the specification, and do not exclude the possibility of the presence or additional addition of one or more other features, numbers, steps, actions, constituent elements, components, or combinations thereof.

[0024] Unless otherwise defined, all terms used herein, including technical or scientific terms, shall have their ordinary meanings as understood by one of ordinary skill in the art. Terms commonly used, such as those defined in dictionaries, shall be understood as having their meanings in the relevant technical context and shall not be interpreted as idealized or overly formalized meanings unless explicitly defined in this specification.

[0025] Furthermore, in the description with reference to the accompanying drawings, the same reference numerals are used for the same constituent elements regardless of the drawing numbers, and repeated descriptions are omitted. In describing the embodiments, detailed descriptions of relevant well-known technologies are omitted when it is determined that such detailed descriptions would unnecessarily obscure the embodiments.

[0026] Furthermore, when describing the constituent elements of the embodiments, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish one constituent element from other constituent elements and are not used to limit the nature or order of the corresponding constituent elements.

[0027] When a constituent element has a common function with a constituent element of a certain embodiment, the same name is used in other embodiments for description. Unless otherwise stated, the description of one embodiment is applicable to other embodiments, and detailed descriptions of repeated content may be omitted.

[0028] Throughout this specification, "aerosol-generating article" can refer to any article capable of generating aerosols, including combustible aerosol-generating articles such as cigarettes and cigars, as well as non-combustible heated aerosol-generating articles. Aerosol-generating articles may include aerosol-generating substances or aerosol-forming matrices. Furthermore, aerosol-generating articles may include solid substances (tobacco media) based on tobacco raw materials such as leaf tobacco, shredded tobacco, and reconstituted tobacco. Aerosol-generating substances may include volatile compounds.

[0029] Furthermore, throughout the instructions, "upstream" or "upstream direction" refers to the direction away from the user's mouth when inhaling the aerosol-generating product, while "downstream" or "downstream direction" refers to the direction towards the user's mouth when inhaling the aerosol-generating product. For example, in Figure 1In the combustion-type aerosol generating article 100 shown, the tobacco medium section 120 is located upstream of or in the upstream direction of the filter section 110.

[0030] Furthermore, in this specification, the aerosol generating article 100 is exemplified by selecting one type of non-combustible (heated) cigarette, such as a combustible cigarette or an electronic cigarette, which is used with an aerosol generating device (not shown), but the present invention is not limited thereto and may include all of the above concepts.

[0031] Additionally, in this specification, "cooling block" can refer to a flavoring or cooling agent composition consisting of a specific combination of cooling agents developed herein to provide a cooling, refreshing sensation and minty aroma similar to those of menthol.

[0032] In addition, in this specification, "packaging paper" refers to paper or other materials used to wrap aerosol-generating products, including cigarette paper wrapping the tobacco medium, rolling paper wrapping the filter, and tipping paper wrapping both the tobacco medium and the filter.

[0033] According to an embodiment of the present invention, a flavoring tablet is provided, comprising a cellulose-based polymer and a cooling block, the cooling block comprising: cooling agent A, wherein cooling agent A is selected from one or more of the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; cooling agent B, wherein cooling agent B is selected from one or more of the group consisting of isoprene alcohol, 4-terpineol, menthone and menthyl acetate; and cooling agent C, wherein cooling agent C is selected from one or more of the group consisting of cis-3-hexenol, hexanol, 1,4-cineole and eucalyptol.

[0034] In addition, according to another embodiment of the present invention, a filter for an aerosol-generating product comprising a cooling block is provided, the cooling block comprising: cooling agent A, wherein cooling agent A is selected from one or more of the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; cooling agent B, wherein cooling agent B is selected from one or more of the group consisting of isoprene alcohol, 4-terpineol, menthone and menthyl acetate; and cooling agent C, wherein cooling agent C is selected from one or more of the group consisting of cis-3-hexenol, hexanol, 1,4-cineole and eucalyptol.

[0035] In addition, according to one embodiment of the present invention, a packaging paper for an aerosol-generating product comprising a cooling block is provided, the cooling block comprising: a cooling agent A, wherein the cooling agent A is selected from one or more of the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; a cooling agent B, wherein the cooling agent B is selected from one or more of the group consisting of isoprene alcohol, 4-terpineol, menthone and menthyl acetate; and a cooling agent C, wherein the cooling agent C is selected from one or more of the group consisting of cis-3-hexenol, hexanol, 1,4-cineole and eucalyptol.

[0036] The cooling agent A contained in the cooling block is a relatively low-volatility base-type cooling agent that can impart a rich and lasting aroma. Specific types of cooling agent A include WS-3 (N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide), WS-23 (N,2,3-trimethyl-2-isopropylbutanamide), and menthyl lactate, etc., and combinations thereof may also be included as needed.

[0037] WS-3 provides a long-lasting cooling sensation, while WS-5 offers a similar cooling sensation but may release unpleasant odors such as saltiness. Additionally, menthyl lactate can provide a certain level of cooling sensation and maintain its duration, while WS-23 can also provide a cooling sensation, but to a lesser degree than menthyl lactate. Compared to WS-23, menthyl lactate can provide a fresher or milder sensation.

[0038] In addition, when used with WS-3, the lactic acid menthol can neutralize the spiciness of WS-3. Taking all factors into consideration, in order to provide a cooling, lasting, refreshing and mild sensation, it is preferable to use WS-3 and lactic acid menthol in combination.

[0039] Furthermore, the content of the low-volatility after-effect cooling agent A contained in the cooling block according to an embodiment of the present invention can be from 10% to 60% by weight, preferably from 15% to 55% by weight, and more preferably from 20% to 50% by weight.

[0040] When the content of cooling agent A exceeds the upper limit, it will disrupt the overall aroma balance (the balance of cooling sensation, minty aroma, freshness, herbal aroma, etc.), resulting in an overly strong aroma that suppresses the aroma of the middle-note cooling agent B and the top-note cooling agent C, leading to a negative effect. When it is below the lower limit, due to the insufficient amount of cooling agent A, the cooling sensation will be reduced, disrupting the overall balance.

[0041] Furthermore, relative to the total weight of the cooling block, the content of WS-3 contained in the cooling agent A may be from 5% to 20% by weight, preferably from 10% to 15% by weight. Additionally, the content of menthyl lactate may be from 5% to 40% by weight, more preferably from 30% to 40% by weight.

[0042] When the contents of WS-3 and menthyl lactate are within the preferred ranges described above, the overall cooling sensation, duration of effect, freshness and gentleness are good, as mentioned above. The differences in effect based on different ranges will be explained in detail in the following examples and comparative examples.

[0043] The cooling agent B contained in the cooling block is a moderately volatile, mid-tone cooling agent that enhances the aroma characteristics. The specific types of cooling agent B can be isoprene alcohol, 4-terpineol, menthone, and menthyl acetate, etc., and combinations thereof may be included as needed.

[0044] Among the types of cooling agents B, menthone imparts a minty aroma, while menthyl acetate is responsible for harmonizing the base, middle, and top notes to prevent the individual characteristics of the base-note cooling agent A and the top-note cooling agent C (described later) from becoming too prominent. Furthermore, isoprene imparts an earthy aroma, and 4-terpineol enhances the roughness. However, isoprene is an expensive ingredient, and the roughness of 4-terpineol can have a negative impact on smokers. Therefore, considering that the purpose of this invention is to achieve properties most similar to menthol, a combination of menthone and menthyl acetate is preferred.

[0045] Furthermore, the content of moderately volatile mid-temperature cooling agent B contained in the cooling block according to an embodiment of the present invention can be from 5% to 50% by weight, preferably from 10% to 45% by weight, and more preferably from 15% to 40% by weight.

[0046] When the content of cooling agent B exceeds the upper limit mentioned above, it will affect the connection between the base-note cooling agent A and the top-note cooling agent C, affecting the overall aroma balance and limiting the unique aroma of the top-note cooling agent C; when it is less than the lower limit mentioned above, the insufficient content of cooling agent B will reduce the minty flavor and affect the overall balance.

[0047] Furthermore, relative to the total weight of the cooling block, the content of menthone contained in the cooling agent B may be from 10% to 30% by weight, preferably from 15% to 25% by weight. Additionally, the content of menthyl acetate may be from 5% to 20% by weight, more preferably from 2% to 8% by weight.

[0048] When the contents of menthone and menthyl acetate are within the above-mentioned preferred range, the aroma intensity and overall balance are good, which can be confirmed by comparing Examples 1 and 2 and Comparative Example 2 below. Furthermore, it also has a minty flavor similar to menthol, and the cooling characteristics as top, middle and base notes are integrated to form an overall balance.

[0049] The cooling agent C contained in the cooling block is a highly volatile top-note cooling agent with strong, unique and dispersible aroma. Specific types of cooling agent C include cis-3-hexenol, hexanol, 1,4-cineole, and eucalyptol, and combinations thereof may also be included as needed.

[0050] Among the types of cooling agent C, cis-3-hexenol can provide a grassy, ​​herbaceous aroma, while hexanol can impart both a grassy scent and an oily feel. Additionally, eucalyptol enhances the minty and cooling sensation, imparting a natural, herbaceous, and fresh aroma. 1,4-Cineole has herbaceous, grassy, ​​fresh, and light aroma characteristics, but its overall harmony is not as good as eucalyptol. Therefore, considering these aspects, eucalyptol is preferred as the cooling agent C.

[0051] Furthermore, the content of the highly volatile pre-cooling agent C contained in the cooling block according to an embodiment of the present invention can be greater than 0% by weight and less than 40% by weight, preferably 0.5% by weight to 10% by weight, or 0.5% by weight to 5% by weight.

[0052] If the content of cooling agent C exceeds the above-mentioned upper limit, it may be impossible to achieve the natural aroma characteristics, resulting in an artificial, overly strong aroma, and it may also disrupt the balance with the middle-note cooling agent B. On the other hand, if cooling agent C is not included, it may be impossible to convey the uniqueness of the spices, resulting in a lack of freshness and pleasure due to the reduced completeness of the aroma.

[0053] The above results can also be confirmed by the sensory evaluation comparison between Examples 1 and 2 described later and Comparative Example 3 which does not contain eucalyptol. It can be seen that the content of cooling agent C in the cooling block is very small. Nevertheless, it has a great influence on the cooling sensation of menthol, the enhancement of aroma intensity and refreshing aftertaste.

[0054] Furthermore, according to an embodiment of the present invention, the cooling block included in flavoring sheets, filters for aerosol-generating articles, or packaging paper may, in addition to the cooling agents A, B, and C described in detail above, also include a solvent for mixing the above-described reagents. In this case, the solvent used may include at least one selected from the group consisting of alcohol, propylene glycol, and glycerol, and is preferably alcohol.

[0055] At this point, the solvent content contained in the chilled food block may be less than about 50% by weight of the total weight of the chilled food block, preferably about 15% to 30% by weight.

[0056] In this way, the balance of cooling agents A, B, and C can be maintained by adjusting the amount of solvent contained in the cooling block, thereby maintaining its role as a substitute for menthol and only adjusting the aroma intensity.

[0057] Furthermore, for example, the preparation method of the cooling block includes: step S1, preparing cooling agent A, cooling agent B, and cooling agent C as raw materials, and step S2, mixing cooling agent A, cooling agent B, and cooling agent C with a solvent; in this case, cooling agent A may be selected from one or more of the group consisting of WS-3, WS-5, WS-23 and menthyl lactate, cooling agent B may be selected from one or more of the group consisting of isoprene alcohol, 4-terpineol, menthone, and menthyl acetate, and cooling agent C may be selected from one or more of the group consisting of cis-3-hexenol, hexanol, 1,4-cineole, and eucalyptol.

[0058] Furthermore, the solvent used in step S2 is essentially the same type as the solvents described above, and is preferably alcohol.

[0059] To prepare a flavored tablet according to an embodiment of the present invention, a slurry (or stock solution) containing distilled water, alcohol, cellulose-based polymer and the cooling block can be prepared. The slurry may also include a bulking agent and / or an emulsifier.

[0060] The distilled water can be a factor that determines the viscosity of the slurry, and alcohol can be used as a solvent, such as ethanol.

[0061] The cellulose-based polymers include at least one selected from the group consisting of methyl cellulose (MC), ethyl cellulose (EC), carboxymethyl cellulose (CMC), carboxyethyl cellulose (CEC), hydroxymethyl cellulose (HMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), and hydroxyethyl methyl cellulose (HEMC). These cellulose-based polymers are readily soluble in alcoholic solvents such as ethanol at room temperature.

[0062] The thickener is used to increase the total mass (i.e., dry mass) of the components other than water in the raw material slurry, thereby increasing the volume of the prepared flavored tablets. The thickener only increases the volume of the flavored tablets and does not substantially increase the viscosity of the raw material slurry, nor does it adversely affect the cooling function of the flavored tablets.

[0063] The preferred types of thickeners are starches or starch hydrolysates. Starch hydrolysates are substances obtained using preparation methods that include a starch hydrolysis step. For example, starch hydrolysates are substances obtained by directly hydrolyzing starch (i.e., dextrin), or substances obtained by hydrolyzing starch after heat treatment (i.e., indigestible dextrin). For example, the thickener can be dextrin, more specifically cyclodextrin.

[0064] The specific type of emulsifier may include lecithin.

[0065] Using a slurry containing the above-mentioned materials, it is spread thinly into sheets, and then dried to produce scented sheets of a certain thickness.

[0066] See Figure 3 As can be seen, the thickness of the flavored chips before the final drying process is d1, while after the final drying process, it becomes thinner, with a thickness of d2. This thickness difference is caused by the difference in moisture content before and after drying. The thickness of the dried flavored chips can range from approximately 5 μm to 300 μm.

[0067] In addition, the drying process can be carried out at a temperature of about 40°C to 70°C.

[0068] Furthermore, a filter for aerosol generation products according to an embodiment of the present invention may include a fiber bundle containing fiber bundles and an adhesive.

[0069] The aforementioned fibers may include at least one selected from the group consisting of cellulose acetate (CA), lyocell, polypropylene (PP), and polylactic acid (PLA); the aforementioned adhesives may include at least one selected from the group consisting of hydroxypropyl methylcellulose, hydroxypropyl cellulose, polyvinyl alcohol (PVA), ethylene vinyl acetate (EVA), and polyvinyl acetate (PVAc).

[0070] The aforementioned fibers are equivalent to the frame (support) forming the filter section, and the aforementioned adhesive is used to connect the multiple fiber bundles forming the frame and the filament bundles formed by the fiber bundles.

[0071] In addition, according to an embodiment of the present invention, the filter includes, in addition to the fiber bundle and the adhesive, a plasticizer for improving the hardness of the filter and an emulsifier for improving the layer separation phenomenon in the mixed solution during the filter preparation process.

[0072] The plasticizer used to increase hardness may be at least one of triethyl citrate (TEC) and triacetine (TA); the emulsifier may include at least one of fatty acid carboxyl compounds, sorbitol ester compounds, sorbate ester compounds, and ethoxy compounds.

[0073] On the other hand, the cooling block prepared by the above preparation method can be directly sprayed onto the packaging paper for aerosol generation products for flavoring treatment (e.g., Transfer Jet Nozzle System (TJNS)). In this case, the packaging paper is a sheet-like packaging paper made of pulp, etc. Specifically, it can be a porous sheet-like packaging paper with a thickness of about 5μm to 150μm, preferably 10μm to 100μm, and more preferably 10μm to 50μm, but it is not limited to this. Different thicknesses can be adopted according to the function of the packaging paper in the location.

[0074] For example, when the packaging paper is used as cigarette paper to wrap the tobacco medium (tobacco portion), in order to prevent leakage of the contents of the portion wrapped by the cigarette paper and to maintain the shape of the aerosol-generating product (smoking product) and to achieve effective combustion, its thickness can be thinner than when it is used as packaging paper for the filter portion (filter roll).

[0075] In addition, according to an embodiment of the present invention, the packaging paper including the cooling block may include, in addition to pulp and the cooling block, at least one additive selected from filler (mineral filler) and combustion improver, and may also include a coating material using a low-flammability material such as a low-flammability metal material.

[0076] The filler can improve whiteness or opacity, control porosity, improve feel and printability, and also reduce paper odor. Examples of fillers with these functions include calcium carbonate (CaCO3), magnesium oxide (MgO), and magnesium carbonate (MgCO3).

[0077] In addition, the combustion aid has the function of promoting or inhibiting combustion, and may include, for example, ammonium phosphate, sodium citrate and potassium citrate.

[0078] When the above-mentioned fillers and combustion improvers are contained in the same way, the cigarette's flavor, combustibility, fire extinguishability, and processability can be ensured.

[0079] According to an embodiment of the present invention, a flavoring tablet including a cooling block, a filter, and a packaging paper can be used in an aerosol-generating article, wherein the aerosol-generating article can be a smoking article including a tobacco medium, a filter, and packaging paper.

[0080] Existing flavoring methods (e.g., TJNS) involve directly spraying flavoring liquid onto the tobacco medium, filter, packaging paper, etc. In this case, when a large amount of flavoring liquid is added, spots may appear on the sprayed objects such as packaging paper due to the increase in solvent. However, when using the method described in this invention, the aerosol-generated product is made into a sheet, which can avoid the above problems and also allows for the addition of a large amount of flavoring, thereby improving consumer smoking satisfaction.

[0081] like Figure 4 As shown, a flavoring sheet including a cooling block is located in the tobacco medium section of the aerosol-generating article, and the flavoring sheet is mixed with the tobacco medium (shredded tobacco). In this way, the flavoring sheet and the tobacco medium are included together in the tobacco medium section, avoiding the defect of the aroma gradually weakening towards the end of smoking as found in existing smoking products, and the cooling block can be continuously released throughout the smoking process.

[0082] In addition, the tobacco medium portion typically contains tobacco materials containing nicotine, such as tobacco leaves, and may also include excipients such as adhesives or other additives. For example, the tobacco medium contained in the tobacco medium portion of the present invention can be prepared in particulate form including tobacco substances and excipients.

[0083] In this invention, the tobacco substance is the material constituting the aerosol-forming substrate, and may be tobacco leaf fragments, tobacco stems, dust generated during tobacco processing, and / or side strips of tobacco leaves. The tobacco leaf may be selected from at least one of yellow tobacco leaves, burley tobacco leaves, oriental tobacco leaves, cigar tobacco leaves, and flue-cured tobacco leaves, but is not limited thereto.

[0084] Furthermore, when the fragrance chip is located in the filter section, the filter section of the aerosol generating product comprises at least two segments, such as a first filter section and a second filter section, regardless of the position of the fragrance chip. If one or more of the aforementioned at least two segments include a fragrance chip according to an embodiment of the present invention, it can be considered to be included within the scope of the present invention. Therefore, the fragrance chip can be located in various filter sections, for example, it can be located inside a paper tube filter.

[0085] Furthermore, if one of the above at least two paragraphs corresponds to a filter including a cooling block according to an embodiment of the present invention, then it can be considered to be included within the scope of the present invention regardless of where it is placed.

[0086] In other words, even if a filter including a cooling block and a filter not including a cooling block are used simultaneously, they are included within the scope of this invention.

[0087] Furthermore, any packaging paper used to wrap the tobacco medium and / or filter portion of a smoking article, as long as it includes at least one of the tobacco medium portion and filter portion wrapped in packaging paper of a cooling block according to an embodiment of the present invention, can be considered to be included within the scope of the present invention.

[0088] In other words, even if both wrapping paper including the cooling block and wrapping paper not including the cooling block are used simultaneously, they are included within the scope of this invention.

[0089] Furthermore, when flavoring sheets are added to the tobacco medium or filter, or when cooling blocks are added to the filter, the amount of cooling blocks added to the flavoring sheets or filter is 50g to 250g, preferably 100g to 105g, relative to 100kg of tobacco medium (tobacco). If the amount of cooling blocks exceeds or falls below this range, the intended cooling block effect of the present invention may be reduced.

[0090] In addition, such as Figure 1As shown in the (combustion-type aerosol generating article), the packaging paper according to an embodiment of the present invention may include packaging paper that wraps each component of the aerosol generating article, and may be divided into tobacco medium portion packaging paper 120a that wraps the tobacco medium portion, filter portion packaging paper (filter roll paper) 110a that wraps the filter, etc. Furthermore, as described above, when the filter portion consists of multiple segments, packaging paper may be included to wrap each segment. Additionally, to securely connect the tobacco medium portion and the filter portion, a splicing paper 130 may be included that wraps a portion of the tobacco medium portion and the filter portion. Furthermore, to maintain the overall shape of the aerosol generating article, an outer packaging paper located on the outermost side of the aerosol generating article may be included that wraps the entire tobacco medium portion and filter portion, etc.

[0091] Optionally, the tipping paper used to combine the tobacco medium and the filter may have at least one perforation formed circumferentially to allow external air to flow in or internal gas to flow out, thereby achieving an air dilution rate of the cigarette and controlling the amount of mainstream smoke components delivered.

[0092] Furthermore, according to an embodiment of the present invention, the cooling block may include, for example, Figure 2 In the non-combustible heated aerosol generating product shown, and its specific location is related to... Figure 1 The basic descriptions are similar, including the tobacco medium section, filter section, and packaging paper.

[0093] According to another aspect of the present invention, a method for preparing a filter for an aerosol-generating article comprising a cooling block is provided, comprising: step S1, preparing a cooling block; step S2, mixing at least one of an adhesive, a plasticizer, and an emulsifier with the cooling block to prepare a mixed solution; and step S3, spraying the mixed solution onto a filament bundle comprising a fiber bundle.

[0094] According to another aspect of the present invention, a method for preparing a filter for an aerosol-generating article comprising a cooling block is provided, comprising: step S1, preparing a cooling block; step S2, mixing at least one of an adhesive, a plasticizer, and an emulsifier with the cooling block to prepare a mixed solution; and step S3, spraying the mixed solution onto a filament bundle comprising a fiber bundle.

[0095] Step S1 in preparing the chilled snack block can be substantially the same as the chilled snack block preparation method described in detail above, and the chilled snack block prepared by this method is also the same as described above.

[0096] As described above, the prepared cooling block is mixed with at least one of an adhesive, a plasticizer, and an emulsifier, and then sprayed onto a filament bundle containing fiber bundles, thereby being contained in a filter; or, in addition to the cooling block, after preparing the filter through steps S2 and S3, the prepared cooling block is sprayed separately to be contained in the filter.

[0097] There are no particular restrictions on the spraying method, but it can be done by spraying directly onto the fiber bundle or filter itself (e.g., TJNS), or by brush spraying or electro-spraying.

[0103] To prepare a cooling block according to an embodiment of the present invention, the flavoring ingredients include powdered WS-3 and menthyl lactate, and liquid menthone, menthyl acetate, and eucalyptol. The prepared WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol ingredients are mixed with alcohol as a solvent and stirred for a specified time to ensure the flavoring ingredients are fully dissolved in the alcohol.

[0104] At this point, the added raw materials and the alcohol content are shown in Table 1 below.

[0105] Example 2

[0106] Except for adjusting the WS-3 content in the cooling agent to 25% by weight and the menthone content to 10% by weight, the cooling block was prepared in the same manner as in Example 1.

[0107] Comparative Example 1

[0108] Except that WS-23 was used instead of WS-3 dissolved in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of WS-23 added this time was 15% by weight of the total weight of the prepared cooling blocks.

[0109] Comparative Example 2

[0110] Except that 4-terpineol was used instead of menthone dissolved in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of 4-terpineol added this time was 20% by weight of the total weight of the prepared cooling blocks.

[0111] Comparative Example 3

[0112] Except that 1,4-cineole was used instead of eucalyptol dissolved in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of 1,4-cineole added this time was 2% by weight of the total weight of the prepared cooling blocks.

[0113] The types and contents of cooling agents in the cooling blocks prepared in Examples 1 to 2 and Comparative Examples 1 to 3 are summarized in Table 1 below.

[0114] [Table 1]

[0115]

[0116] (All values ​​in Table 1 above are in weight percent)

[0117] (2) Preparation Example 2: Preparation of flavored tablets containing cooling blocks

[0118] Before preparing the flavored tablets, the chilled block from Example 1 is prepared and mixed with distilled water, ethanol, methyl cellulose (MC), and cyclodextrin to prepare a flavored tablet slurry with appropriate viscosity.

[0119] The prepared flavored flake slurry is spread into thin sheets and then dried at 60°C to prepare the flavored flake containing cooling blocks of the present invention with a certain thickness.

[0120] (3) Experimental Example 1: Sensory evaluation of the prepared chilled snack blocks

[0121] A 16-person evaluation team from KT&G R&D evaluated the aerosol-generated tobacco products containing the flavored tablets with cooling blocks from Examples 1-2 and Comparative Examples 1-3, which were prepared as described above, after smoking them. The evaluations assessed the flavor intensity, menthol coolness, smoothness of swallowing, aroma intensity, overall balance, refreshing aftertaste, and overall satisfaction, with a maximum score of 9 points. The average evaluation results are shown in Table 2 below.

[0122] [Table 2]

[0123]

[0124]

[0125] Referring to Table 2, the evaluation results of Examples 1 and 2, which contain all of WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol, showed better results in terms of aroma intensity, menthol coolness, aroma intensity, overall balance, refreshing aftertaste, and overall satisfaction compared to Comparative Examples 1 to 3, which lack WS-3, menthone, and eucalyptol.

[0126] More specifically, Comparative Example 1, which lacked WS-3, performed poorly in all evaluation categories, particularly in aroma intensity and aftertaste freshness; while Comparative Example 2, which lacked menthone, performed poorly in aroma intensity and overall balance. Comparative Example 3, which lacked eucalyptol, scored lower than the examples in menthol coolness, aroma intensity, overall balance, and aftertaste freshness.

[0127] Therefore, it can be seen that smokers had a higher overall satisfaction with Examples 1 and 2 than with Comparative Examples 1 to 3.

[0128] On the other hand, when comparing Examples 1 and 2 with different contents of WS-3 and menthone, Example 2, which added excessive WS-3 or a small amount of menthone, was slightly inferior in terms of menthol coolness, smoothness of swallowing, aroma intensity, overall balance and refreshing aftertaste, and its overall satisfaction was lower than that of Example 1.

[0129] (4) Experiment Example 2: Sensory evaluation comparison with existing tobacco products

[0130] A comparison was made between the aerosol-generated product of the flavored tablets prepared in Example 2 and the existing ESSE CHANGE. 1mg

[0131] The flavored tablet containing cooling block prepared in Preparation Example 2 was applied to aerosol-generated products.

[0132] Subsequently, a 13-person evaluation team was formed within KT&G R&D. The team members were found to be using existing [products / methods]. ESSE CHANGE 1 mg (for the test sample, preparation) ESSE CHANGE After a product was prepared by mixing 1mg of menthol in two flavorings with an aerosol containing the cooling block from Example 1, the flavor intensity, menthol coolness, smoothness of swallowing, aroma intensity, overall balance, refreshing aftertaste, and satisfaction were evaluated, with a maximum score of 9 points. The average value of the evaluation results is shown in Table 3 below.

[0133] [Table 3]

[0135]

[0136] A comparison was made between the aerosol-generated product of the flavored tablets prepared in Example 2 and the conventional ESSE CHANGE. 1mg

[0137] A 16-person evaluation team was formed within KT&G R&D. The team members were found to be using regular... ESSE CHANGEAfter generating an aerosol product by mixing 1 mg (the test product, in which menthol and cooling block were not mixed in the two flavoring processes) with the flavored tablet containing cooling block from Preparation Example 2, the product was evaluated according to the same method described above. The average value of the evaluation results is shown in Table 4 below.

[0138] [Table 4]

[0139]

[0140] A comparison was made between the aerosol-generated product, including the chilled snack block from Preparation Example 2, and the existing Raison French product. Black

[0141] A 16-person evaluation team from KT&G R&D conducted evaluations after members inhaled existing Raison FrenchBlack aerosol products and flavored tablets containing cooling blocks, including those from Preparation Example 2, using the same method described above. The average evaluation results are shown in Table 5 below.

[0142] [Table 5]
