Description

Technical Field

[0001] The present invention relates to a tobacco sheet for a non-combustion heating type flavor attractor, a method for manufacturing the same, a non-combustion heating type flavor attractor, and a non-combustion heating type flavor attracting system.

Background Art

[0002] In a combustion type flavor attractor (cigarette), a tobacco filler including tobacco leaves or a tobacco sheet is burned to obtain a flavor. For example, Patent Document 1 discloses a tobacco sheet used for a combustion type flavor attractor. As an alternative to the combustion type flavor attractor, a non-combustion heating type flavor attractor that obtains a flavor by heating a flavor source such as a tobacco sheet instead of burning it has been proposed. The heating temperature of the non-combustion heating type flavor attractor is lower than the combustion temperature of the combustion type flavor attractor, for example, about 400 ° C or lower. Thus, since the heating temperature of the non-combustion heating type flavor attractor is low, an aerosol generator can be added to the flavor source in the non-combustion heating type flavor attractor from the viewpoint of increasing the amount of smoke. The aerosol generator is vaporized by heating to generate an aerosol. Since the aerosol is supplied to the user together with flavor components such as tobacco components, the user can obtain a sufficient flavor.

[0003] The non-combustion heating type flavor attractor can include, for example, a tobacco-containing segment filled with a tobacco sheet or the like, a cooling segment, and a filter segment. The axial length of the tobacco-containing segment of the non-combustion heating type flavor attractor is usually shorter than the axial length of the tobacco-containing segment of the combustion type flavor attractor in relation to the heating heater. Therefore, in the non-combustion heating type flavor attractor, in order to ensure the amount of aerosol generated during heating, a large amount of tobacco sheet is filled in the short tobacco-containing segment. In order to fill a large amount of tobacco sheet in a short section, a tobacco sheet having a low swelling property, that is, a high density, is usually used in the non-combustion heating type flavor attractor. Note that the swelling property is a value indicating the volume when the cut of a tobacco sheet of a predetermined mass is compressed at a constant pressure for a constant time.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when the inventors considered the heating method, the heating capacity of the heater, and the generation of aerosol, they found that when using a tobacco sheet with low bulkiness (high density), the total heat capacity of the tobacco-containing segment becomes high. Depending on the heating method and the capacity of the heater, the tobacco sheet filled in the tobacco-containing segment may not sufficiently contribute to aerosol generation. To solve this problem, it is conceivable to reduce the total heat capacity of the tobacco-containing segment.

[0006] In order to reduce the total heat capacity of the tobacco-containing segment, the inventors considered (1) reducing the specific heat of the tobacco raw material contained in the tobacco sheet and (2) using a tobacco sheet with high bulkiness (low density). However, regarding (1), it is difficult to reduce the specific heat of the tobacco raw material itself, so it was considered effective to reduce the total heat capacity of the tobacco-containing segment by (2). Therefore, the development of a tobacco sheet with high bulkiness (low density) that is preferably used in a non-combustion heating type flavor inhaler is desired.

[0007] An object of the present invention is to provide a tobacco sheet for a non-combustion heating type flavor inhaler with high bulkiness, a non-combustion heating type flavor inhaler including the tobacco sheet, and a non-combustion heating type flavor inhalation system.

[0011] [Tobacco Sheet for Non-Combustion Heating Type Flavor Attractor] The tobacco sheet for a non-combustion heating type flavor attractor according to the present embodiment (hereinafter also referred to as "tobacco sheet") contains a tobacco raw material, and the cross-section in the thickness direction of the tobacco sheet has a corrugated shape. Since the cross-sectional shape in the thickness direction of the tobacco sheet according to the present embodiment is corrugated, it is bulky and has high swelling properties. Therefore, by using the tobacco sheet according to the present embodiment, the total heat capacity of the tobacco-containing segment can be reduced, and the tobacco sheet filled in the tobacco-containing segment can sufficiently contribute to aerosol generation. Further, the tobacco sheet according to the present embodiment preferably further contains an aerosol generator and one or more kinds of molding agents, and by setting the blending ratio of these within a predetermined range, the swelling property of the tobacco sheet is further improved.

[0012] (Shape of the tobacco sheet) The tobacco sheet according to this embodiment has a corrugated shape in the cross-section in the thickness direction. That is, when the tobacco sheet according to this embodiment is cut in the thickness direction in a certain direction in the plane direction, the shape of the cross-section has a corrugated shape. The certain direction in the plane direction may be, for example, the longitudinal direction of the tobacco sheet or the short-side direction. Here, the "corrugated" is not particularly limited as long as it is a shape that undulates up and down. The peak of the wave may have a linear shape or a curved shape. Also, the waves may be regular or irregular.

[0013] An example of the cross-sectional shape in the thickness direction of the tobacco sheet according to this embodiment is shown in FIG. 1. The tobacco sheet 1 shown in FIG. 1 has waves 2 in the cross-section in the thickness direction. The width w1 of the wave 2 is not particularly limited, but is preferably within the range of 0.1 to 10.0 mm. Also, the height w2 of the wave 2 is not particularly limited, but is preferably within the range of 0.1 to 5.0 mm. The thickness w3 of the tobacco sheet 1 is preferably within the range of 100 to 1000 μm. As shown in FIG. 1, the wave 2 may have a sawtooth shape 3. By the wave 2 having the sawtooth shape 3, voids can be further formed by the tips of the sawtooth shapes contacting each other in the mixture of the tobacco sheets, and as a result, the bulking property can be further improved. The size of the tobacco sheet according to this embodiment in the plane direction is not particularly limited, but can be, for example, length: 5.0 to 40.0 mm, width: 0.5 to 2.0 mm.

[0014] (Tobacco raw material) As the tobacco raw material contained in the tobacco sheet according to the present embodiment, there is no particular limitation as long as it contains tobacco components, and examples thereof include tobacco powder and tobacco extract. Examples of the tobacco powder include leaf tobacco, midrib, and stalk. These may be used alone or in combination of two or more. By cutting these to a predetermined size, they can be used as tobacco powder. From the viewpoint of further improving the swelling property, it is preferable that the cumulative 90% particle diameter (D90) in the volume-based particle size distribution measured by the dry laser diffraction method is 200 μm or more as the size of the tobacco powder. When the tobacco raw material is tobacco powder, the proportion of the tobacco powder contained in 100% by mass of the tobacco sheet is preferably 45 to 95% by mass, more preferably 50 to 93% by mass, and even more preferably 60 to 85% by mass. Examples of the tobacco extract include a tobacco extract obtained by crushing leaf tobacco, mixing and stirring this with a solvent such as water to extract water-soluble components from the leaf tobacco, and drying and concentrating the obtained water extract under reduced pressure.

[0015] (Aerosol generator) From the viewpoint of increasing the amount of smoke during heating, the tobacco sheet according to the present embodiment preferably further contains an aerosol generator. Examples of the aerosol generator include glycerin, propylene glycol, 1,3-butanediol, and the like. These may be used alone or in combination of two or more.

[0016] When the tobacco sheet contains an aerosol generator, the proportion of the aerosol generator contained in 100% by mass of the tobacco sheet is preferably 4 to 50% by mass. When the proportion of the aerosol generator is 4% by mass or more, sufficient aerosol can be generated during heating from the viewpoint of the amount. Also, when the proportion of the aerosol generator is 50% by mass or less, sufficient aerosol can be generated during heating from the viewpoint of the heat capacity. The proportion of the aerosol generator is more preferably 6 to 40% by mass, even more preferably 8 to 30% by mass, and particularly preferably 10 to 20% by mass.

[0017] (Molding agent) From the viewpoint of shape retention, the tobacco sheet according to this embodiment preferably further contains a molding agent. In particular, from the viewpoint of sufficiently achieving both the aerosol generator retention performance and the corrugated shape maintenance performance of the tobacco sheet, the tobacco sheet according to this embodiment preferably further contains a first molding agent and a second molding agent. Here, the first molding agent and the second molding agent may have different types of molding agents, or may have the same type of molding agent but different forms. Examples of the first molding agent include polysaccharides, proteins, synthetic polymers, etc. Examples of polysaccharides include cellulose derivatives and naturally derived polysaccharides.

[0018] Examples of cellulose derivatives include cellulose ethers such as methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxymethylethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, benzyl cellulose, trityl cellulose, cyanoethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, aminoethyl cellulose, etc.; organic acid esters such as cellulose acetate, cellulose formate, cellulose propionate, cellulose butyrate, cellulose benzoate, cellulose phthalate, cellulose tosylate, etc.; inorganic acid esters such as cellulose nitrate, cellulose sulfate, cellulose phosphate, cellulose xanthate, etc.

[0019] Examples of naturally derived polysaccharides include, for example, guar gum, tara gum, locust bean gum KaPlant-derived polysaccharides such as stevengum, tamarind seed gum, pectin, gum arabic, tragacanth gum, karaya gum, gatti gum, arabinogalactan, amashi seed gum, kasshagum, psyllium seed gum, sabaku yomogi seed gum, etc.; algal-derived polysaccharides such as carrageenan, agar, alginic acid, propylene glycol alginate, furcellaran, nori extract, etc.; microbial-derived polysaccharides such as xanthan gum, gellan gum, curdlan, pullulan, Agrobacterium succinoglycan, welan gum, macrohomoopsis gum, rhamsan gum, etc.; polysaccharides derived from crustaceans such as chitin, chitosan, glucosamine, etc.; starches such as starch, sodium starch glycolate, pregelatinized starch, dextrin, etc.

[0020] Examples of the protein include cereal proteins such as wheat gluten and rye gluten. Examples of the synthetic polymer include polyphosphoric acid, sodium polyacrylate, polyvinylpyrrolidone, etc. As the second molding agent, although different from the first molding agent, the same polysaccharides, proteins, synthetic polymers, etc. as the first molding agent can be used.

[0021] When the first molding agent is contained in the tobacco sheet, the proportion of the first molding agent contained in 100% by mass of the tobacco sheet is preferably 0.1 to 15% by mass. When the proportion of the first molding agent is 0.1% by mass or more, the mixture of raw materials can be easily molded into a sheet shape. Also, when the proportion of the first molding agent is 15% by mass or less, other raw materials required to ensure the functions required for the tobacco-containing segment of the non-combustion heating type flavor attractor can be sufficiently used. The proportion of the first molding agent is more preferably 0.1 to 12% by mass, further preferably 0.1 to 10% by mass, and particularly preferably 0.1 to 7% by mass.

[0022] When the tobacco sheet contains a second molding agent, the proportion of the second molding agent contained in 100% by mass of the tobacco sheet is preferably 0.1 to 15% by mass. When the proportion of the second molding agent is 0.1% by mass or more, the raw material mixture can be easily formed into a sheet shape. Further, when the proportion of the second molding agent is 15% by mass or less, other raw materials for ensuring the functions required for the tobacco-containing segment of the non-combustion heating type flavor inhaler can be sufficiently used. The proportion of the second molding agent is more preferably 0.1 to 12% by mass, further preferably 0.1 to 10% by mass, and particularly preferably 0.1 to 7% by mass.

[0023] Further, when the first molding agent and the second molding agent are the same in type of molding agent but different in form, for example, the first molding agent can be powder and the second molding agent can be a solution or slurry. For example, in the method for producing a tobacco sheet described later, the molding agent can be directly mixed as powder as the first molding agent, and the molding agent can be dispersed or swollen in a solvent such as water and mixed as the second molding agent. Even in such a method, the same effects as those obtained when two different types of molding agents are used can be obtained.

[0024] (Reinforcing agent) From the viewpoint of further improving physical properties, the tobacco sheet according to the present embodiment can further contain a reinforcing agent. Examples of the reinforcing agent include fibrous substances such as fibrous pulp and fibrous synthetic cellulose, and liquid substances having a surface coating function that form a film when dried, such as pectin suspension water. These may be used alone or in combination of two or more.

[0025] When the tobacco sheet contains a reinforcing agent, the proportion of the reinforcing agent contained in 100% by mass of the tobacco sheet is preferably 4 to 40% by mass. Within this range, other raw materials for ensuring the functions required for the tobacco-containing segment of the non-combustion heating type flavor inhaler can be sufficiently used. The proportion of the reinforcing agent is more preferably 4.5 to 35% by mass, and further preferably 5 to 30% by mass.

[0026] (Humectant) From the perspective of quality retention, the tobacco sheet according to the present embodiment can further contain a humectant. Examples of the humectant include sugar alcohols such as sorbitol, erythritol, xylitol, maltitol, lactitol, mannitol, and reduced maltose syrup. These may be used alone or in combination of two or more.

[0027] When the tobacco sheet contains a humectant, the proportion of the humectant contained in 100% by mass of the tobacco sheet is preferably 1 to 15% by mass. Within this range, other raw materials for ensuring the functions required for the tobacco-containing segment of the non-combustion heating type flavor attractor can be sufficiently used. The proportion of the humectant is more preferably 2 to 12% by mass, and even more preferably 3 to 10% by mass.

[0028] (Other components) In addition to the tobacco raw material, the aerosol generator, the molding agents (the first and second molding agents), the reinforcing agent, and the humectant, the tobacco sheet according to the present embodiment can contain, as necessary, flavoring agents such as fragrances and flavoring agents, colorants, wetting agents, preservatives, diluents such as inorganic substances, and the like.

[0029] (Swelling property) The bulkiness of the tobacco sheet according to this embodiment is preferably 190 cc / 100 g or more. When the bulkiness is 190 cc / 100 g or more, the total heat capacity of the tobacco-containing segment of the non-combustion heating type flavor inhaler can be sufficiently reduced, and the tobacco sheet filled in the tobacco-containing segment can contribute to aerosol generation. More preferably, the bulkiness is 210 cc / 100 g or more, and even more preferably 230 cc / 100 g or more. The upper limit of the range of the bulkiness is not particularly limited, but it can be, for example, 800 cc / 100 g or less. The bulkiness is a value measured with a DD-60A (trade name, manufactured by Borgward) after cutting the tobacco sheet into a size of 0.8 mm × 20 mm and storing it in a conditioning chamber at 22°C and 60% for 48 hours. The measurement is performed by placing 15 g of the cut tobacco sheet in a cylindrical container with an inner diameter of 60 mm and determining the volume when compressed with a 3 kg load for 30 seconds.

[0030] [Method for manufacturing tobacco sheet] The tobacco sheet according to this embodiment Manufacturing method can include, for example, a step of preparing a mixture containing a tobacco raw material, an aerosol generator, a first molding agent, and a second molding agent, a step of rolling the mixture to form a rolled product, and a step of pressing a rotary roll blade against the rolled product to cut it into strips while imparting a corrugated shape. The process of imparting a corrugated shape is also referred to as a rippling process. For example, the tobacco sheet according to this embodiment can be manufactured by the following method.

[0031] (1) A step of mixing water, a tobacco raw material, an aerosol generator, first and second molding agents, and a reinforcing agent to obtain a mixture. (2) A step of charging the mixture into a plurality of rolling rollers and rolling it to obtain a rolled product. (3) A step of pressing a rotary roll blade against the rolled product to cut it into strips while imparting a corrugated shape.

[0032] When the sheet cut into strips by the rotary roll blade is peeled off from the roll, a resistance force is applied, thereby imparting a corrugated shape and a serrated shape as shown in FIG. 1. When the rolled product is not cut by the rotary roll blade, for example, when the rolled product on the rolling roller is peeled off with a doctor knife, a resistance force is applied when it is peeled off from the roll, and similarly, a corrugated shape and a serrated shape can be imparted. Further, when manufacturing the tobacco sheet by the above method, the surface of the rolling roller may be heated or cooled according to the purpose, or the rotation speed of the rolling roller may be adjusted. Furthermore, by adjusting the interval between the rolling rollers, a tobacco sheet having a desired basis weight can be obtained.

[0033] [Non-combustion heating type flavor inhaler] The non-combustion heating type flavor inhaler according to the present embodiment includes a tobacco-containing segment including a tobacco sheet or the like according to the present embodiment. Since the non-combustion heating type flavor inhaler according to the present embodiment includes a tobacco-containing segment filled with a highly bulgy tobacco sheet or the like according to the present embodiment, the total heat capacity of the tobacco-containing segment can be sufficiently reduced, and the tobacco sheet filled in the tobacco-containing segment can contribute to aerosol generation.

[0034] An example of the non-combustion heating type flavor inhaler according to the present embodiment is shown in FIG. 2. The non-combustion heating type flavor inhaler 4 shown in FIG. 2 includes a tobacco-containing segment 5 filled with a tobacco sheet or the like according to the present embodiment, a cylindrical cooling segment 6 having perforations 11 on the circumference, a center hole segment 7, and a filter segment 8. The non-combustion heating type flavor inhaler according to the present embodiment may have other segments in addition to the tobacco-containing segment, the cooling segment, the center hole segment, and the filter segment.

[0035] The axial length of the non-combustion heating type flavor attractor according to this embodiment is not particularly limited, but is preferably 40 mm or more and 90 mm or less, more preferably 50 mm or more and 75 mm or less, and even more preferably 50 mm or more and 60 mm or less. Also, the circumferential length of the non-combustion heating type flavor attractor is preferably 16 mm or more and 25 mm or less, more preferably 20 mm or more and 24 mm or less, and even more preferably 21 mm or more and 23 mm or less. For example, a mode can be cited in which the length of the tobacco-containing segment is 20 mm, the length of the cooling segment is 20 mm, the length of the center hole segment is 8 mm, and the length of the filter segment is 7 mm. Note that the length of the filter segment can be selected within the range of 4 mm or more and 10 mm or less. Also, the ventilation resistance of the filter segment at that time is selected so as to be 15 mmHg2O / seg or more and 60 mmHg2O / seg or less per segment. These individual segment lengths can be appropriately changed according to manufacturing suitability, required quality, etc. Furthermore, even if only the filter segment is arranged on the downstream side of the cooling segment without using the center hole segment, it can function as a non-combustion heating type flavor attractor.

[0036] (Tobacco-containing segment) The tobacco-containing segment 5 has the tobacco sheet according to this embodiment filled in a wrapper (hereinafter also referred to as a wrapper). The method of filling the tobacco sheet into the wrapper is not particularly limited. For example, the tobacco sheet may be wrapped with a wrapper, or the tobacco sheet may be filled into a cylindrical wrapper. When the shape of the tobacco sheet has a longitudinal direction like a rectangular shape, the tobacco sheet may be filled so that the longitudinal direction is an unspecified direction in the wrapper, or may be filled so as to be aligned in the axial direction of the tobacco-containing segment 5 or a direction perpendicular to the axial direction.

[0037] (Cooling segment) As shown in FIG. 2, an example of the cooling segment 6 being composed of a cylindrical member 10 can be cited. The cylindrical member 10 may be, for example, a paper tube obtained by processing cardboard into a cylindrical shape.

[0038] The cylindrical member 10 and the mouthpiece lining paper 15 described later are provided with perforations 11 penetrating both of them. Due to the presence of the perforations 11, outside air is introduced into the cooling segment 6 during suction. As a result, the aerosol vaporization components generated by heating the tobacco-containing segment 5 come into contact with the outside air, and their temperature drops, causing liquefaction and the formation of an aerosol. The diameter (span length) of the perforations 11 is not particularly limited, and for example, it may be 0.5 mm or more and 1.5 mm or less. The number of the perforations 11 is not particularly limited, and it may be one or two or more. For example, a plurality of the perforations 11 may be provided on the circumference of the cooling segment 6.

[0039] The amount of outside air introduced from the perforations 11 is preferably 85% by volume or less, more preferably 80% by volume or less, based on the total volume of the gas sucked by the user. By the proportion of the outside air amount being 85% by volume or less, it is possible to sufficiently suppress the reduction of the flavor due to dilution by the outside air. Incidentally, this is also referred to as the ventilation ratio in another way. From the viewpoint of coolability, the lower limit of the range of the ventilation ratio is preferably 55% by volume or more, more preferably 60% by volume or more.

[0040] Further, the cooling segment may be a segment including a wrinkled, pleated, gathered, or folded sheet of a suitable constituent material. The cross-sectional profile of such an element may show randomly oriented channels. Also, the cooling segment may include a bundle of longitudinally extending tubes. Such a cooling segment can be formed, for example, by winding a pleated, gathered, or folded sheet material with a wrapping paper.

[0041] The axial length of the cooling segment can be, for example, 7 mm or more and 28 mm or less, and can be, for example, 18 mm. Also, the cooling segment can be substantially circular in its axial cross-sectional shape, and its diameter can be, for example, 5 mm or more and 10 mm or less, and can be, for example, about 7 mm.

[0042] (Center hole segment) The center hole segment is composed of a filling layer having one or more hollow portions and an inner plug wrapper (inner winding paper) covering the filling layer. For example, as shown in FIG. 2, the center hole segment 7 is composed of a second filling layer 12 having a hollow portion and a second inner plug wrapper 13 covering the second filling layer 12. The center hole segment 7 has a function of enhancing the strength of the mouthpiece segment 9. The second filling layer 12 can be a rod with an inner diameter of 1.0 mm or more and 5.0 mm or less, which is filled with high-density cellulose acetate fibers and has a plasticizer containing triacetin added in an amount of 6% by mass or more and 20% by mass or less based on the mass of the cellulose acetate and is cured. Since the second filling layer 12 has a high fiber filling density, when sucking, air and aerosol will only flow through the hollow portion, and hardly flow inside the second filling layer 12. Since the second filling layer 12 inside the center hole segment 7 is a fiber filling layer, the feel from the outside during use is less likely to cause discomfort to the user. Note that the center hole segment 7 may not have the second inner plug wrapper 13 and its shape may be maintained by thermoforming.

[0043] (Filter segment) The configuration of the filter segment 8 is not particularly limited, and it may be composed of one or more filling layers. The outside of the filling layer may be wound with one or more sheets of winding paper. The ventilation resistance per segment of the filter segment 8 can be appropriately changed according to the amount and material of the filler filled in the filter segment 8. For example, when the filler is cellulose acetate fiber, increasing the amount of cellulose acetate fiber filled in the filter segment 8 can increase the ventilation resistance. When the filler is cellulose acetate fiber, the filling density of the cellulose acetate fiber can be 0.13 - 0.18 g / cm 3 It can be. The ventilation resistance is the value measured by a ventilation resistance measuring instrument (trade name: SODIMAX, manufactured by SODIM).

[0044] The length around the filter segment 8 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The axial length of the filter segment 8 can be selected from 4 to 10 mm, and is selected so that its ventilation resistance is 15 to 60 mmH2O / seg. The axial length of the filter segment 8 is preferably 5 to 9 mm, and more preferably 6 to 8 mm. The cross-sectional shape of the filter segment 8 is not particularly limited, and can be, for example, circular, elliptical, polygonal, etc. Also, the filter segment 8 may contain a destructive capsule containing a fragrance, fragrance beads, or the fragrance may be directly added.

[0045] As shown in FIG. 2, the center hole segment 7 and the filter segment 8 can be connected by an outer plug wrapper (outer wrapping paper) 14. The outer plug wrapper 14 can be, for example, a cylindrical paper. Also, the tobacco-containing segment 5, the cooling segment 6, and the connected center hole segment 7 and filter segment 8 can be connected by a mouthpiece lining paper 15. These connections can be made, for example, by applying an adhesive such as a vinyl acetate-based adhesive to the inner surface of the mouthpiece lining paper 15 and wrapping the three segments. Note that these segments may be connected in multiple times using multiple lining papers.

[0046] [Non-combustion heating type flavor inhalation system] The non-combustion heating type flavor inhalation system according to the present embodiment includes the non-combustion heating type flavor inhaler according to the present embodiment and a heating device that heats the tobacco-containing segment of the non-combustion heating type flavor inhaler. The non-combustion heating type flavor inhalation system according to the present embodiment may have other configurations in addition to the non-combustion heating type flavor inhaler and the heating device according to the present embodiment.

[0047] An example of the non-combustion heating type flavor attracting system according to this embodiment is shown in FIG. 3. The non-combustion heating type flavor attracting system shown in FIG. 3 includes a non-combustion heating type flavor attractor 4 according to this embodiment and a heating device 16 that heats the tobacco-containing segment of the non-combustion heating type flavor attractor 4 from the outside.

[0048] FIG. 3(a) shows the state before the non-combustion heating type flavor attractor 4 is inserted into the heating device 16, and FIG. 3(b) shows the state where the non-combustion heating type flavor attractor 4 is inserted into the heating device 16 and heated. The heating device 16 shown in FIG. 3 includes a body 17, a heater 18, a metal tube 19, a battery unit 20, and a control unit 21. The body 17 has a cylindrical recess 22, and the heater 18 and the metal tube 19 are arranged at a position corresponding to the tobacco-containing segment of the non-combustion heating type flavor attractor 4 that is inserted into the recess 22 on the inner side surface of the recess 22. The heater 18 can be a heater by electric resistance, and power is supplied from the battery unit 20 according to an instruction from the control unit 21 that performs temperature control, and the heater 18 is heated. The heat generated from the heater 18 is transmitted to the tobacco-containing segment of the non-combustion heating type flavor attractor 4 through the metal tube 19 having a high thermal conductivity.

[0049] In FIG. 3(b), since it is schematically illustrated, there is a gap between the outer periphery of the non-combustion heating type flavor attractor 4 and the inner periphery of the metal tube 19, but actually, it is desirable that there is no gap between the outer periphery of the non-combustion heating type flavor attractor 4 and the inner periphery of the metal tube 19 for the purpose of efficiently transmitting heat. Note that the heating device 16 heats the tobacco-containing segment of the non-combustion heating type flavor attractor 4 from the outside, but it may be one that heats from the inside.

[0050] The heating temperature by the heating device is not particularly limited, but it is preferably 400°C or lower, more preferably 150°C or higher and 400°C or lower, and even more preferably 200°C or higher and 350°C or lower. Note that the heating temperature indicates the temperature of the heater of the heating device.

[0051] Furthermore, for non-combustion heating type flavor inhalers, reduction of flavor inhibition feeling (irritation) or discomfort is required. The flavor inhibition feeling means irritation to the oral cavity or throat during inhalation. Hereinafter, a tobacco sheet for a non-combustion heating type flavor inhaler with reduced flavor inhibition feeling or discomfort will be described.

[0052] [First Aspect] In this aspect, the tobacco sheet for a non-combustion heating type flavor inhaler contains fructan. When the tobacco sheet is used for smoking, the fructan undergoes thermal decomposition to continuously generate a sweet aroma. The generated continuous sweet aroma can suppress the flavor inhibition feeling from the initial stage to the later stage of the smoking behavior.

[0053] The fructan is not particularly limited, but inulin-type fructan, levan-type fructan, branched fructan, fructooligosaccharide, or a combination of two or more of these can be used. Among these, from the perspective of cost reduction, inulin-type fructan is preferred.

[0054] Although not bound by theory, when the fructan in this aspect generates a sweet aroma through the Maillard reaction, it is presumed to have the following characteristics. Fructan is formed by the bonding of multiple monosaccharides and has a molecular structure larger than monosaccharides and disaccharides. Therefore, when fructan undergoes the Maillard reaction, it is considered to go through a multi-step decomposition process in which it decomposes into relatively small molecules of sugar such as monosaccharides and disaccharides, and then these monosaccharides and disaccharides undergo the Maillard reaction to generate a sweet aroma. On the other hand, when monosaccharides and disaccharides undergo the Maillard reaction, it is considered that these sugars directly undergo the Maillard reaction to generate a sweet aroma. Therefore, it is considered that fructan can generate a sweet aroma at a slower rate and for a longer time compared to monosaccharides and disaccharides due to the greater number of decomposition steps. In this aspect, due to the characteristics of the Maillard reaction of fructan as described above, it is considered that the flavor inhibition feeling can be suppressed continuously from the initial stage to the later stage of the smoking behavior.

[0055] In some embodiments, the content of fructan relative to 100% by mass of the tobacco sheet is not particularly limited, but can be 0.1 to 5% by mass, 0.3 to 3.5% by mass, or 0.5 to 3% by mass. Smoking Taste From the viewpoint of suppressing the sense of irritation and smoking Taste From the viewpoint of the persistence of suppressing the sense of irritation, a higher content of fructan is preferred. On the other hand, if the content of fructan is too high, the flavor may be reduced. Therefore, smoking Taste From the viewpoint of achieving both the suppression of the sense of irritation and its persistence and the flavor, the content of fructan is preferably 0.5 to 3% by mass.

[0056] In this aspect, the tobacco raw material can further include tobacco leaves, aged tobacco leaves, processed tobacco leaves, tobacco fillers, non-tobacco materials, or a combination of two or more of these.

[0057] <Tobacco leaves, aged tobacco leaves, and processed tobacco leaves> The "tobacco leaves" is a general term for the harvested tobacco leaves before undergoing the aging described below. Note that one aspect of aging includes curing. On the other hand, the tobacco leaves that have undergone aging and are before being processed into various forms (tobacco cuts, tobacco sheets, tobacco granules, etc. described below) used in tobacco products are referred to as "aged tobacco leaves". Further, the processed tobacco leaves obtained by processing the aged tobacco leaves into various forms used in tobacco products are referred to as "processed tobacco leaves".

[0058] Examples of the form of the processed tobacco leaves used in tobacco products include, for example, "tobacco cuts" obtained by cutting the aged tobacco leaves into a predetermined size. Also, a "tobacco sheet" obtained by forming a composition containing the aged tobacco leaves ground to a predetermined particle size (hereinafter also referred to as "tobacco fine powder") into a sheet shape, and a "tobacco granule" obtained by forming it into a granule shape can also be mentioned. Note that the "tobacco fine powder" is also a form of processed tobacco leaves.

[0059] Examples of the non-tobacco material include plant roots (including bulbous roots (bulbs), tuberous roots (tubers), corms, etc.), stems, tubers, barks (including stem barks, tree barks, etc.), leaves, flowers (including petals, pistils, stamens, etc.), or seeds, or tree trunks, branches, etc.

[0060] The method for manufacturing the tobacco sheet containing fructan is not limited. In some embodiments of the present application, it can be manufactured by preparing the above-mentioned tobacco sheet and supplying fructan from the outside. Specifically, it is preferable to supply fructan to the roll-formed product. The roll-formed product may be before or after being given a corrugated shape.

[0061] [Second Aspect] In this aspect, the tobacco sheet for a non-combustion heating type flavor inhaler contains a saturated fatty acid-based additive. In this aspect, the tobacco sheet may contain a material derived from an oriental variety. In that case, the content of the material derived from the oriental variety with respect to the tobacco raw material is preferably 10% by mass or less. When the content of the material derived from the oriental variety is within this range, a taste with a reduced unpleasant feeling can be provided. From this viewpoint, the upper limit of the content is preferably 8% by mass or less, more preferably 5% by mass or less. The lower limit is preferably 0.1% by mass or more, more preferably 2% by mass or more, and still more preferably 3% by mass or more.

[0062] The saturated fatty acid-based additive is selected from the group consisting of a saturated fatty acid having a molar mass of 200 to 350 g / mol, an ester of the saturated fatty acid, and a combination thereof. The saturated fatty acid reduces the unpleasant feeling during smoking. Since the ester of the saturated fatty acid is obtained from an alcohol and a saturated fatty acid having a molar mass of 200 to 350 g / mol, the molar mass of the ester varies depending on the molar mass of the alcohol. The molar mass of the ester is 210 to 1300 g / mol in one aspect. Since the ester of the saturated fatty acid generally has a lower vapor pressure than the fatty acid, the unpleasant feeling reduction effect during smoking is sustained throughout smoking. Hereinafter, the unpleasant feeling reduction effect during smoking is also simply referred to as the unpleasant feeling reduction effect.

[0063] From the viewpoint of achieving the above effects, the lower limit of the molar mass of the saturated fatty acid ester is preferably 240 g / mol or more, more preferably 270 g / mol or more. The upper limit is preferably 1140 g / mol or less, 1112 g / mol or less, 300 g / mol or less, or 290 g / mol or less.

[0064] The content of the saturated fatty acid-based additive is 0.01 to 3% by mass per 100% by mass of the total dry mass of the tobacco raw material. If the content is less than the lower limit, the effect of reducing discomfort is insufficient, and if it exceeds the upper limit, the unpleasant odor increases. From this viewpoint, the lower limit of the content is preferably 1% by mass or more, and the upper limit is preferably 2% by mass or less. The dry mass is the mass excluding the medium described later, and is preferably the mass of the residue when the composition is dried at 100°C for 5 hours.

[0065] The number of carbon atoms in the fatty acid moiety of the saturated fatty acid and the ester is preferably 12 to 20, more preferably 15 to 19. When the number of carbon atoms is in this range, the effect of reducing discomfort becomes more prominent. The solubility of the saturated fatty acid in the saturated fatty acid-based additive in water is preferably 0.15 mg / g or less, more preferably 0.12 mg / g or less. The lower limit is not limited and may be 0 mg / g, but is preferably 0.05 mg / g or more.

[0066] Preferable specific examples of the saturated fatty acid include octanoic acid, decanoic acid, myristic acid, palmitic acid, stearic acid, and nonadecanoic acid. Among them, from the viewpoints of easy availability and the expression of the unpleasant feeling reduction effect, palmitic acid, stearic acid, or nonadecanoic acid is preferable. The saturated fatty acid may be a mixture, but it is preferably a single product rather than a mixture. In this embodiment, a single product (single compound) includes the case where the compound is a pure product and the case where the compound contains unavoidably contained impurities. Therefore, in one aspect, the saturated fatty acid consists only of palmitic acid. When the saturated fatty acid is a single product, when the tobacco composition of the present invention is made into a molded article such as a sheet, the dispersibility of the saturated fatty acid in the molded article is improved.

[0067] Preferable specific examples of the ester of the saturated fatty acid (hereinafter also simply referred to as "ester") include the alkyl esters and sugar esters of the aforementioned saturated fatty acids. The alkyl moiety is preferably derived from a linear, branched, or cyclic alkyl group having 1 to 10 carbon atoms such as a methyl group. Also, the sugar moiety is preferably derived from a disaccharide such as sucrose. Examples of the preferable ester include sucrose palmitate and methyl palmitate. The saturated fatty acid moiety in the ester is preferably derived from a single product saturated fatty acid for the aforementioned reasons. The alcohol moiety in the ester does not necessarily need to be a single product, but is preferably a single product for the aforementioned reasons. The ester also has a function as an emulsifier.

[0068] In one aspect, the saturated fatty acid-based additive includes the saturated fatty acid and the ester. In this case, there is an advantage that the unpleasant feeling reduction effect can be made more sustainable. Also, depending on the tobacco raw material used, etc., the type of the saturated fatty acid-based additive can be appropriately selected. Therefore, this aspect also has the advantage of being versatile.

[0069] Part or all of the saturated fatty acid-based additive is preferably in powder form. When the saturated fatty acid-based additive is in powder form, the dispersibility of the saturated fatty acid-based additive in a molded article such as a sheet is improved as described later. Its size is not limited, but for example, the D50 is preferably 30 to 120 μm, more preferably 50 to 100 μm. Further, from the viewpoint of the dispersibility, the saturated fatty acid-based additive preferably has a higher crystallinity than waxes and natural fats and oils.

[0070] The tobacco sheet may contain liquid sugar. Liquid sugar is liquid sugar. When the tobacco sheet contains liquid sugar, in addition to reducing the discomfort during smoking, the sweetness is improved. From this viewpoint, the content of liquid sugar is preferably 3 to 10% by mass, more preferably 5 to 8% by mass, per dry matter mass in the tobacco composition.

[0071] The tobacco sheet may contain a natural plant-based fragrance. When the tobacco sheet contains a natural plant-based fragrance, in addition to the discomfort-reducing effect, the sweetness is improved. From this viewpoint, the content of the natural plant-based fragrance is preferably 0.5 to 3% by mass, more preferably 2 to 3% by mass, per dry matter mass in the tobacco composition. As the natural plant-based fragrance, those known in the tobacco field can be used, but in the present invention, licorice is preferred. Licorice is a sweetener derived from Spanish licorice, which belongs to the genus Glycyrrhiza of the legume family.

[0072] The amount of nicotine contained in the tobacco sheet in this embodiment is not limited, but in one embodiment, it can be 2% by mass or more per dry matter mass of the tobacco sheet. Generally, as the amount of nicotine increases, the discomfort during smoking tends to increase. However, in this embodiment, since the discomfort-reducing effect is exhibited as described above, the effect of this embodiment becomes more prominent when the amount of nicotine is within the above range. The upper limit of the amount of nicotine is not limited, but in reality, it is 3% by mass or less.

[0073] In another aspect, the amount of nicotine can be 1.5% by mass or less. When the nicotine amount is within the above range, a milder smoking flavor can be imparted. The lower limit of the nicotine amount is not limited, but in reality, it is 0.1% by mass or more. The nicotine contained in the tobacco sheet may be derived from the tobacco raw material or from other components.

[0074] The tobacco sheet in this aspect can contain the above-described aerosol generator. The amount of the aerosol generator is preferably 12% by mass or less, more preferably 11% by mass or less, per dry matter mass of the tobacco sheet. Also, the lower limit value is not limited and may be 0% by mass, preferably 1% by mass or more. If the amount of the aerosol generator exceeds the upper limit value, there is a possibility that the production of the sheet becomes difficult, and if it is less than the lower limit value, there is a possibility that the amount of smoke sensation decreases.

[0075] When the tobacco sheet contains a binder, the strength of the sheet is improved. The binder is an adhesive for binding fibers and the like. As the binder, those known in the art can be used. Examples of the binder include gums, modified celluloses, and thickening polysaccharides such as modified starches. The amount of the binder is appropriately adjusted according to the application, but for example, it can be about 1 to 10% by mass per dry matter mass of the tobacco sheet.

[0076] The tobacco sheet in this aspect is produced by an arbitrary method. For example, when preparing the above mixture, a saturated fatty acid-based additive is mixed, and the additive is made into a compounded mixture, and a sheet can be produced by the above-described method using this. At that time, it is preferable to use a powdered saturated fatty acid-based additive and mix it so as to maintain its powder state. The tobacco sheet produced in this way has good dispersibility of the aerosol generator. Good dispersibility means that the saturated fatty acid-based additive is uniformly dispersed. The mixing step is preferably carried out at a temperature below the melting point of the saturated fatty acid-based additive. For example, this step can be carried out at 10 to 50°C.

[0077] A mixture containing a saturated fatty acid-based additive (also referred to as a "slurry") is preferably produced by a method comprising the following steps. A step of mixing the tobacco raw material or fibrous tobacco material, a saturated fatty acid-based additive that is partially or entirely in powder form, and a medium to form a slurry such that the powder maintains its powder state.

[0078] In this method, a slurry is prepared while the saturated fatty acid-based additive remains in a powder state. By doing so, the dispersibility of component (B) is improved when formed into a molded body. The size of the powder is as described above. That the saturated fatty acid-based additive maintains its powder state means that a part or all of it maintains its powder state.

[0079] Examples of the medium include water and hydrophilic organic solvents, but from the perspective of handling, the most preferred medium is water.

[0080] This method preferably comprises a step of first pulverizing a solid material into powder at room temperature and mixing them to obtain a powder mixture. On the other hand, a liquid mixture is obtained by mixing a liquid or paste-like material such as a medium at room temperature. Then, the powder mixture and the liquid mixture are mixed.

[0081] From the perspective of well-dispersing the powdered saturated fatty acid-based additive in the medium, the viscosity of the slurry at 25°C is preferably 100,000 to 200,000 (mPa·s). The viscosity is measured using a B-type viscometer (DV-I prime manufactured by Brookfield), spindle No. LV4, and a rotation speed of 1.0 rpm.

[0082] [Third Aspect] In this embodiment, the tobacco-containing segment (hereinafter also simply referred to as "tobacco segment") includes paper or paper containing an aerosol-generating agent. The outline of the tobacco segment in this embodiment is shown in FIG. 4A. The tobacco segment 20A includes a tobacco filler 21 and a wrapper 22 that wraps around it. The tobacco filler 21 includes the tobacco sheet T and the paper P. In this figure, the tobacco sheet T is in a strand shape obtained by cutting it, and the paper P is also in a strand shape. The strand may be obtained by cutting a sheet in which the tobacco sheet T and the paper P are laminated. In the drawings for explaining this embodiment, the illustration of the corrugated shape of the tobacco sheet T is omitted.

[0083] FIG. 4B shows a mode in which the sheet-shaped tobacco filler 21 is filled into the wrapper 22 in a spiral shape. The sheet-shaped tobacco filler 21 may be a sheet in which the tobacco sheet T and the paper P are laminated, or a sheet obtained by joining the side surfaces or the vicinity of the side surfaces of the tobacco sheet T and the paper P.

[0084] FIG. 4C shows a mode in which the sheet-shaped tobacco filler 21 is folded and filled into the wrapper 22. The sheet-shaped tobacco filler 21 may be a sheet in which the tobacco sheet T and the paper P are laminated, or a sheet obtained by joining the side surfaces or the vicinity of the side surfaces of the tobacco sheet T and the paper P.

[0085] FIG. 4D shows a mode in which the engraved tobacco filler 21 is filled into the wrapper 22. In this figure, a mode of preparing and filling the engraving obtained from the tobacco sheet T and the engraved paper P respectively is shown. The engraving may be obtained by cutting a sheet in which the tobacco sheet T and the paper P are laminated.

[0086] FIG. 4E shows a mode in which the sheet-shaped tobacco filler 21 is compressed and rounded from the vertical and horizontal directions and filled into the wrapper 22. The sheet-shaped tobacco filler 21 may be a sheet in which the tobacco sheet T and the paper P are laminated, or a sheet obtained by joining the side surfaces or the vicinity of the side surfaces of the tobacco sheet T and the paper P.

[0087] (1) Paper (1-1) Aspect 3-1 As the tobacco segment in the 3-1 aspect, as a filler, it includes a tobacco sheet and paper with a total content of lignin and hemicellulose of 0.1 to 10% by mass. The said filler is a filler for the tobacco segment. Lignin is a high molecular phenolic compound contained in wood etc. Hemicellulose is an insoluble polysaccharide contained in the cell wall. When the total amount is within this range, the abnormal odor (such as fiber odor) during smoking can be reduced. That is, in this aspect, the effect that the flavor can be diluted without significantly inhibiting the original flavor is achieved. From this viewpoint, the upper limit of the total content of lignin and hemicellulose is preferably 9.0% by mass or less.

[0088] Lignin and hemicellulose are measured by known methods, but in the present invention, it is preferably measured by the following method. [Quantification of hemicellulose] 1) The paper is subjected to solvent extraction using water as a solvent, and the residue is separated. The residue is cryogenically pulverized using liquid nitrogen etc. to obtain sample A. 2) Sample A is reacted with an enzyme, and the reaction product is recovered. 3) The reaction product is hydrolyzed, the absorbance of the hydrolyzate is measured at a wavelength of 490 nm, and hemicellulose is quantified.

[0089] Step 1) can use, for example, Thermo Scientific TM Dionex TM ASE TM A high-speed solvent extraction system (model number: ASE-350).

[0090] Step 2) can be specifically implemented as follows. Put 50 mg of sample A into a screw bottle, add 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution, and shake at 40 °C and 125 rpm for 16 hours. The pancreatin solution is the supernatant obtained by adding 8 g of pancreatin to 100 ml of 0.1 M phosphate buffer at pH 6.4, stirring for 1 hour, and then centrifuging at 8000 rpm for 30 minutes. Then, transfer the sample liquid to a 15 ml centrifuge tube using ML-Q water, centrifuge at 8000 rpm for 15 minutes, and remove the supernatant. Repeat this washing three times. After washing, add 10 ml of 5% sulfuric acid aqueous solution and perform hydrolysis at 100 °C for 2.5 hours. After the hydrolysis reaction is completed, let the sample cool to room temperature. Then, filter off the precipitate and collect the filtrate in a 250 ml volumetric flask. Thoroughly wash the residue on the filter paper with ML-Q water and then make up to 250 ml. This solution is used as a sample for hemicellulose measurement. Transfer 500 μl of this sample to a 20 ml test tube, add 500 μl of 5% phenol aqueous solution and 2.5 ml of concentrated sulfuric acid, and stir vigorously for 10 seconds. Leave the sample standing at room temperature for 20 minutes or more, measure the absorbance at a wavelength of 490 nm using a spectrophotometer, and quantify the hemicellulose.

[0091] [Quantification of lignin] i) Prepare the above sample A. ii) Reflux sample A in an acidic aqueous solution, and filter the sample after the reflux treatment. iii) After drying the filtered sample, weigh it to obtain the lignin content.

[0092] Steps ii) and iii) can be specifically implemented as follows. Put 100 mg of sample A into a screw bottle, add 4 ml of 72% sulfuric acid, completely immerse the sample in the sulfuric acid, and shake at 30 °C and 200 rpm for 4 hours. Then, add 157.2 ml of ultrapure water (ML-Q water) so that the diluted sulfuric acid concentration becomes 4%, transfer it to an eggplant flask, and perform heating reflux in an oil bath at 110 °C for 2 hours. After cooling to room temperature, filter, dry with a rotary dry heat machine, and weigh.

[0093] The density of the paper used in this embodiment is preferably 0.05 - 0.8 (g / cm 3) and more preferably 0.1 to 0.6 (g / cm 3 ). The density is measured by a known method, but it is preferably determined by the following formula. Density (g / cm 3 ) = weight (g) / area (cm 2 ) / thickness (cm)

[0094] The content of the paper used in this embodiment is preferably 5 to 70% by mass, more preferably 10 to 50% by mass, and still more preferably 15 to 40% by mass based on the dry matter mass of the tobacco sheet. When the content of the paper is within this range, the smoking flavor can be diluted to an appropriate level without inhibiting the original smoking flavor. The dry matter mass is, in one aspect, the mass of the residue when the tobacco sheet is dried at 100 °C for 5 hours.

[0095] The paper used in this embodiment is not limited as long as the total content of lignin and hemicellulose is within the above range. For example, tobacco paper such as wrapper or printing paper such as high-quality printing paper and medium-quality printing paper can be used. However, from the viewpoint of suppressing the generation of abnormal odor, it is preferably uncoated paper or lightly coated paper. Further, the paper used in this embodiment may or may not contain an aerosol generator described later. The amount may be within the range described in the third - second embodiment or may be outside this range.

[0096] (1 - 2) Third - second embodiment The tobacco segment, as a third - second aspect, includes, as a filler, a tobacco sheet and a paper containing an aerosol - generating agent. An aerosol - generating agent is a material that vaporizes upon heating and is cooled to generate an aerosol or generates an aerosol by atomization. In this aspect, since paper containing an aerosol - generating agent is used, there is an effect that the smoking flavor can be diluted without reducing the amount of smoke. As the aerosol - generating agent, those described above can be used. The amount thereof is preferably 3 - 20% by mass, more preferably 5 - 15% by mass, per dry mass of the paper. If the amount of the aerosol - generating agent exceeds the upper limit, seepage or the like may occur in the tobacco segment, and if it is less than the lower limit, the amount of smoke sensation may decrease. The aerosol - generating agent can be added to the paper by impregnation, spraying, or the like.

[0097] The content of the paper added with the aerosol - generating agent is preferably 5 - 75% by mass, more preferably 10 - 50% by mass, and even more preferably 15 - 40% by mass, based on the dry mass of the tobacco sheet.

[0098] The paper used in this aspect is not limited and may be the paper described in the third - first aspect. The density of the paper before adding the aerosol - generating agent used in this aspect may be within the range described in the third - first aspect or may be outside this range. Also, the amounts of lignin and hemicellulose contained in the paper used in this aspect are not limited and may be within the range described in the third - first aspect or may be outside this range.

[0099] (1 - 3) Shape, etc. In any aspect, the shape of the paper is not limited and may be a shape that is easy to mix with the tobacco sheet. In one aspect, the paper is a sheet, flake, or strand. Also, in a preferred aspect, the shapes of the paper and the tobacco sheet are the same, and in the most preferred aspect, the flakes of the paper and the tobacco sheet are used.

[0100] Also, flavors such as menthol, which are commonly used in this field, may be added to the paper.

Examples

[0101] Hereinafter, specific examples of the present embodiment will be described, but the present invention is not limited thereto.

[0102] [Example 1] Tobacco lamina (leaf tobacco) was dry-ground using a Hosokawa Micron ACM machine to obtain tobacco powder. Regarding the tobacco powder, the cumulative 90% particle diameter (D90) in the volume-based particle size distribution measured by the dry laser diffraction method was measured using a Mastersizer (trade name, manufactured by Malvern Panalytical, Spectris Co., Ltd.) and found to be 200 μm.

[0103] Using the tobacco powder as a tobacco raw material, a tobacco sheet was produced. Specifically, 70 parts by mass of the tobacco raw material, 12 parts by mass of glycerin as an aerosol generator, 4 parts by mass of powdered carboxymethyl cellulose as a first molding agent, 1 part by mass of carboxymethyl cellulose swollen with water as a second molding agent, 5 parts by mass of fibrous pulp as a reinforcing agent, and 8 parts by mass of cocoa powder as a flavor were mixed and kneaded using an extrusion molding machine. The kneaded product was formed into a sheet shape using two pairs of metal rolls to obtain a rolled product. A rotary roll blade for noodle making was pressed against the rolled product to impart a corrugated shape while cutting it into strips. Further, it was cut to a length of 20 mm and dried to obtain a tobacco sheet having a length of 20 mm and a width of 0.8 mm. The cross-section in the thickness direction of the tobacco sheet had a cross-sectional shape as shown in FIG. 1.

[0104] The swelling property of the obtained tobacco sheet was measured. Specifically, after the tobacco sheet was left in a conditioning chamber at 22°C and 60% for 48 hours, the swelling property was measured using a DD-60A (trade name, manufactured by Borgward). The measurement was performed by placing 15 g of the tobacco sheet in a cylindrical container with an inner diameter of 60 mm and determining the volume when compressed with a 3 kg load for 30 seconds. The results are shown in Table 1. In Table 1, the swelling property is shown as the increase rate (%) of the swelling property with respect to the swelling property value of Comparative Example 1 described later.

[0105] [Comparative Example 1] A rolled product was produced in the same manner as in Example 1. Thereafter, it was cut into strips with a plurality of ring-shaped rotary blades. Further, by cutting so that the length became 20 mm, a tobacco sheet having a length of 20 mm and a width of 0.8 mm and without a corrugated shape was obtained. About the obtained tobacco sheet, the swelling property was measured in the same manner as in Example 1. The results are shown in Table 1.

[0106]

Table 1

[0107] From Table 1, in the tobacco sheet of Example 1 which is the tobacco sheet according to the present embodiment, the swelling property was improved as compared with the tobacco sheet of Comparative Example 1 in which the corrugated shape was not imparted.

[0108] [Reference Example 1a] 1. Preparation of Smoking Composition Sheet A tobacco sheet (smoking composition sheet) manufactured by a known papermaking method was prepared. The tobacco sheet was filled into a wrapper to form a smoking segment, and a non-combustible heat-type flavor suction shown in FIG. 2 was prepared. Device was prepared.

[0109] 2. Preparation of Fructan or Fructose-Containing Smoking Composition Sheet To 90 g of a mixed solution of propylene glycol and water (propylene glycol: water = 1:9 (mass ratio)), 10 g of inulin-type fructan (manufactured by Fuji Nihon Seito Co., Ltd., product name Fuji FF) was added and mixed to obtain a solution of inulin-type fructan. Then, the same tobacco sheet as in 1. above was prepared, and the solution of inulin-type fructan was added using a syringe so as to cover the entire tobacco sheet, whereby the content of inulin-type fructan in the entire smoking composition sheet after addition (containing inulin-type fructan) was 0.5, 1.0, 2.0, 3.0, or 3.5 mass% to obtain each sheet.

[0110] Further, 10 g of fructose (manufactured by Hopps Food Industry Co., Ltd., product name: fructose) was added to and mixed with 90 g of a mixed solution of propylene glycol and water (propylene glycol: water = 1:9 (mass ratio)) to obtain a fructose solution. Then, the same tobacco sheet as in 1. above was prepared, and the fructose solution was added using a syringe so as to cover the entire tobacco sheet, whereby sheets having a fructose content of 0.5, 1.0, 2.0, 3.0, or 3.5% by mass with respect to the entire smoking composition sheet (containing fructose) after addition were obtained.

[0111] The fructan-containing smoking composition sheet or fructose-containing smoking composition sheet obtained as described above was filled into a wrapper to form a smoking segment, and a non-combustion heating type flavor inhalation shown in FIG. 2 Device was prepared.

[0112] The above inulin-type fructan is a kind of fructan, and the smoking composition sheet containing inulin-type fructan corresponds to an example of the present application. On the other hand, the above fructose is a kind of monosaccharide, and the smoking composition sheet containing fructose corresponds to a comparative example of the present application.

[0113] 3. Evaluation of flavor and flavor inhibition feeling Each non-combustion heating type flavor inhalation prepared as in 1 or 2 above Device was installed in the non-combustion external heating type smoking system shown in FIG. 3. Regarding each flavor inhalation prepared in this way Device the flavor and the flavor inhibition feeling were evaluated by 10 well-trained panelists. In this example and the comparative example, "flavor" means the combined flavor of the tobacco-derived flavor and the sweet flavor derived from inulin-type fructan or fructose. The evaluation of the flavor and the feeling of flavor inhibition of each smoking test sheet was carried out by each panelist evaluating according to the five - level criteria in Table 1a below and calculating the average value of 10 panelists. In the criteria of Table 1a below, a value equivalent to that compared with a sheet containing no inulin - type fructan or fructose is regarded as 3. When the average value has a value in the second decimal place, the score was calculated by rounding off the second decimal place. The evaluation results are shown in Tables 2a and 3a and Figure 5.

Table 3a

[0117] As described above, the smoking composition sheet containing inulin - type fructan corresponds to the example of the present application, while the smoking composition sheet containing fructose corresponds to the comparative example of the present application.

[0118] From the results of Table 2a and Figure 5, it was found that as the content of inulin - type fructan increased, the numerical value of the feeling of flavor inhibition decreased, indicating that the feeling of flavor inhibition could be suppressed. In particular, when the content of inulin - type fructan was 3.0% by mass or more, the numerical value of the feeling of flavor inhibition became 1, indicating that the feeling of flavor inhibition could be extremely strongly suppressed. Thus, it was found that in terms of suppressing the feeling of flavor inhibition, a larger content of inulin - type fructan was preferable. On the other hand, it was found that as the content of inulin - type fructan increased, the flavor tended to decrease. When emphasizing the flavor, since a flavor numerical value of 1.5 or more was desirable, it was found that from the viewpoint of achieving both the flavor and the suppression effect of the feeling of flavor inhibition, the content of inulin - type fructan was preferably 0.5 - 3% by mass.

[0119] On the one hand, from the results of Table 3a and Figure 5, it was found that the addition of fructose also has an effect of suppressing a certain sense of flavor inhibition. However, compared with the inulin-type fructan shown in Table 2a and Figure 5, it was found that fructose has a low and insufficient effect of suppressing the sense of flavor inhibition.

[0120] In addition, regarding fructose, there was a comment from the panelists that the sense of flavor inhibition increases in the latter half of smoking (the effect of suppressing the sense of flavor inhibition does not last long). Therefore, as shown in the following Reference Example 2 a A comparative experiment was conducted on the persistence of the effect of suppressing the sense of flavor inhibition with respect to inulin-type fructan and fructose.

[0121] [Reference Example 2a] 1. Evaluation of the persistence of the effect of suppressing the sense of flavor inhibition The non-combustion heating type flavor attractant prepared in the same manner as in "2. Preparation of a smoking composition sheet containing fructan or fructose" of the above Reference Example 1a Device was installed in the non-combustion external heating type smoking system shown in Figure 3 . Regarding each flavor attractant prepared in this way Device , the persistence of the effect of suppressing the sense of flavor inhibition was evaluated by 10 well-trained panelists. The evaluation of the persistence of the effect of suppressing the sense of flavor inhibition for each smoking test roll was carried out by each panelist evaluating the effect of suppressing the sense of flavor inhibition until the latter half of smoking and the absence of the remaining sense of flavor inhibition after smoking according to the 5-level criteria in Table 4a below, and calculating the average value of the 10 panelists. When the average value has a value in the second decimal place, the score was calculated by rounding off the second decimal place. In the criteria in Table 4a below, when evaluating the persistence of the effect of suppressing the sense of flavor inhibition due to the difference in the content of inulin-type fructan, a value equivalent to that compared with the sheet containing 2.0% by mass of fructose is set as 3. Also, when evaluating the persistence of the effect of suppressing the sense of flavor inhibition due to the difference in the content of fructose, a value equivalent to that compared with the sheet containing 2.0% by mass of inulin-type fructan is set as 3. The evaluation results are shown in Tables 5a and 6a and Figure 6.

[0122] [Table 4a]

[0123] [Table 5a]

[0124] [Table 6a]

[0125] From the results of Table 5a and Figure 6, it was found that inulin-type fructan is superior to 2.0% by mass of fructose as the comparison target in terms of the persistence of the inhibitory effect on the flavor and taste inhibition feeling at any content of 0.5 to 3.5% by mass. Also, from the results of Table 6a and Figure 6, it was found that fructose is inferior to 2.0% by mass of inulin-type fructan as the comparison target in terms of the persistence of the inhibitory effect on the flavor and taste inhibition feeling at any content of 0.5 to 3.5% by mass. Since inulin-type fructan undergoes a thermal decomposition process before generating a sweet flavor by the caramelization reaction, it is considered to generate a sweet flavor slowly over a long time. On the other hand, fructose is considered to generate a sweet flavor in a short time by the caramelization reaction. Since the flavor and taste inhibition feeling is suppressed by the sweet flavor, it is considered that the difference in the generation time of such a sweet flavor causes the difference in the persistence of the inhibitory effect on the flavor and taste inhibition feeling. From the above results, it was confirmed that inulin-type fructan is superior to fructose in terms of the persistence of the inhibitory effect on the flavor and taste inhibition feeling.

[0126] From the above, it was found that the tobacco material in this example has a suppressed flavor and taste inhibition feeling continuously from the initial stage to the late stage of the smoking behavior (excellent in the persistence of the inhibitory effect on the flavor and taste inhibition feeling).

[0127] [Reference Example 1b] As component (A), a tobacco sheet for papermaking was prepared. The sheet contained 15% by mass of vegetable glycerin as a tobacco material and an aerosol generator. As component (B), the saturated fatty acids shown in Table 1b were prepared and sprayed onto the sheet. The addition amount of component (B) per dry matter mass of the tobacco composition (the total of the tobacco sheet for papermaking and component (B)) was as shown in Table 1b. For example, in Example A1, the addition amount of octanoic acid per dry matter mass of the tobacco composition was 1.0% by mass.

[0128] [Table 1b]

[0129] After drying the sheet, a plurality of slits were provided and then wound up to obtain a tobacco rod. At this time, the longitudinal direction of the slits was made parallel to the longitudinal direction of the tobacco segments. Using the tobacco rod, a non-combustion heating type tobacco flavor inhaler having the structure shown in FIG. 2 Device was manufactured. The length of each segment was as follows. Tobacco segment: 12 mm Center hole part: 8 mm Paper tube: 20 mm Acetate filter: 40 mm Using a hollow cylindrical heater with an outer diameter of 3.2 mm and an inner diameter of 1.3 mm, the non-combustion heating type tobacco flavor inhaler Device was heated under the following conditions to conduct a smoking test. Voltage: Set to an applied voltage of 3.0 V Temperature profile: Constant at 320 °C Preheating time (before the start of smoking): After inserting the heater into the winding part, it was heated for 30 seconds By 10 well-trained panelists, using the Visual Analog Scale (category scale) method, a non-combustion heating type tobacco flavor inhaler Device (lower Reference reference Comparison example reference) was used as a comparison target for the test. The results are shown in Table 1b. A lower score difference means less discomfort.

[0130] [Reference Comparative Example 1b] A non-combustion heating type tobacco flavor attractant was produced in the same manner as in Reference Example 1b, except that component (B) was not used. Device

[0131] [Reference Example 2b] The following materials were prepared. Component (A): Tobacco lamina (other than Oriental species), tobacco lamina (Oriental species) Component (B): Palmitic acid, sucrose palmitate Others: Licorice, liquid sugar, softwood pulp, glycerin, binder (guar gum)

[0132] A non-combustion heating type tobacco flavor attractant was produced and evaluated according to the following procedure. Device 1) The tobacco lamina was pulverized with a lab mill to obtain tobacco fine powder with a raw material particle size D90 = 100 μm. 2) Granular palmitic acid and sucrose palmitate were pulverized with a lab mill to obtain a powder. 3) The softwood pulp was disintegrated with a lab mill. 4) These powdered materials were put into a Ken mixer and stirred and mixed. 5) Liquid or paste-like materials such as water, glycerin, licorice, liquid sugar, and binder were put into a disperser (manufactured by Primix) in the mixer and mixed for 30 minutes. 6) The pulp was added to this mixture and dispersed with a disperser (manufactured by Primix) for 30 minutes. 7) The powder mixture obtained in 4) was added to the dispersion obtained in 6) and mixed with a disperser (manufactured by Primix) for 30 minutes. 8) The mixture obtained in 7) was cast on an iron plate. 9) The iron plate on which the cast film was formed was placed in a ventilation dryer set at 80 °C and dried for 30 minutes, and then peeled off from the iron plate to obtain a sheet-like tobacco composition. The thickness of the sheet was 150 μm and the basis weight was 150 g / m 2 10) The sheet-like tobacco composition was shredded to obtain a shredded tobacco composition of 1 mm × 10 mm.​​​ 11) A specified amount of shredded tobacco composition was rolled up with a wrapping paper into a size of φ7×20 mm to produce a single roll. 12) The single roll was used as a tobacco rod, and a non-combustion heated tobacco flavor inhalation Device was obtained. 13) The non-combustion heated tobacco flavor inhalation Device was inserted into a heating device (PloomS manufactured by Japan Tobacco Inc.), heated, and subjected to a smoking evaluation. A sensory evaluation was conducted by ten well-trained panelists. The evaluation results are shown in Table 2b.

Device was manufactured and evaluated.

[0134] [Table 2b]

[0135] From the above, it is clear that the tobacco preparation of this example reduces the discomfort during smoking.

[0136] [Reference Comparative Example 1c] A tobacco sheet manufactured by a known papermaking method was prepared. The tobacco sheet was used as a tobacco segment filled in a wrapper, and a non-combustion heated flavor inhalation shown in FIG. 2 Device was prepared. For the Fragrance attractor , a smoking test was conducted by ten well-trained panelists (average age 40 years).

[0144] [Quantification of hemicellulose] 1) The paper was subjected to solvent extraction (solvent: water) using a Thermo Scientific TM Dionex TM ASE TM high-speed solvent extraction system (model number: ASE-350) to separate the residue. The residue was cryogenically pulverized using liquid nitrogen or the like to obtain Sample A. 2) 50 mg of Sample A was placed in a screw bottle, 8.5 ml of ultrapure water (ML-Q water) and 0.5 ml of pancreatin solution were added, and the mixture was shaken at 40 °C and 125 rpm for 16 hours. Then, the sample liquid was transferred to a 15 ml centrifuge tube using ML-Q water and centrifuged at 8000 rpm for 15 minutes to remove the supernatant. This washing was repeated three times. After washing, 10 ml of 5% sulfuric acid aqueous solution was added, and hydrolysis was carried out at 100 °C for 2.5 hours. After the hydrolysis reaction was completed, the sample was allowed to cool to room temperature. Then, the precipitate was filtered off, and the filtrate was collected in a 250 ml volumetric flask. The residue on the filter paper was thoroughly washed with ML-Q water and then made up to 250 ml. This solution was used as a sample for hemicellulose measurement. 3) 500 μl of the sample was transferred to a 20 ml test tube, 500 μl of 5% phenol aqueous solution and 2.5 ml of concentrated sulfuric acid were added, and the mixture was vigorously stirred for 10 seconds. The sample was allowed to stand at room temperature for 20 minutes or more, and the absorbance was measured at a wavelength of 490 nm using a spectrophotometer to quantify hemicellulose.
