Description

TOBACCO SHEET FOR NON-COMBUSTION HEATING FLAVOR INSPIRATION AND MANUFACTURING METHOD THEREOF, NON-COMBUSTION HEATING FLAVOR INSPIRATION, AND NON-COMBUSTION HEATING FLAVOR SUCTION SYSTEM

The present invention relates to a tobacco sheet for a non-combustion heating flavor inhaler, a manufacturing method thereof, a non-combustion heating flavor inhaler, and a non-combustion heating flavor inhalation system.

A combustion-type flavor inhaler (cigarette) obtains flavor by burning tobacco fillings including leaf tobacco and tobacco sheets. For example, Patent Literature 1 discloses a tobacco sheet used in a combustion type flavor inhaler. As an alternative to the combustion type flavor inhaler, a non-combustion heating type flavor inhaler has been proposed that obtains flavor by heating a flavor source such as a tobacco sheet instead of burning it. The heating temperature of the non-combustion heating type flavor inhaler is lower than the combustion temperature of the combustion type flavor inhaler, for example, about 400° C. or less. Thus, since the heating temperature of the non-combustion heating type flavor inhaler is low, an aerosol generating agent can be added to the flavor source in the non-combustion heating type flavor inhaler from the viewpoint of increasing the amount of smoke. The aerosol-generating agent 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 sufficient flavor.

A non-combustion heating flavor inhaler can comprise, for example, a tobacco-containing segment filled with tobacco sheets or the like, a cooling segment, and a filter segment. The axial length of the tobacco-containing segment of the non-combustion-heating flavor inhaler is generally shorter than the axial length of the tobacco-containing segment of the normal combustion-type flavor inhaler in relation to the heating heater. Therefore, in the non-combustion heating type flavor inhaler, a large amount of tobacco sheets are filled in the short tobacco-containing segments in order to secure the amount of aerosol generated during heating. In order to fill a large amount of tobacco sheets in a short section, non-combustion heating type flavor inhalers usually use tobacco sheets with low swelling, that is, high density tobacco sheets. In addition, the swelling property is a value indicating the volume of a tobacco sheet having a predetermined mass when notches are compressed under a constant pressure for a certain period of time.

Japanese Patent Publication No. 60-45914

However, considering the heating method, the heating capacity of the heater, and the generation of aerosol, the present inventors believe that if a tobacco sheet with low swelling (high density) is used, the total heat capacity of the tobacco-containing segment increases. It was found that the tobacco sheet filled in the tobacco-containing segment does not sufficiently contribute to the generation of aerosol depending on the heating method and the capacity of the heater. In order to solve this problem, it is conceivable to reduce the total heat capacity of the tobacco-containing segment.

In order to reduce the total heat capacity of the tobacco-containing segment, the present inventors (1) reduce the specific heat of the tobacco raw material contained in the tobacco sheet, and (2) use a highly bulky (low-density) tobacco sheet. I considered using it. However, as for (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, it is desired to develop a highly bulky (low density) tobacco sheet suitable for non-combustion heating type flavor inhalers.

An object of the present invention is to provide a highly bulky non-combustion heating flavor inhaler tobacco sheet, a non-combustion heating flavor inhaler including the tobacco sheet, and a non-combustion heating flavor inhalation system.

It is a value measured by The measurement is carried out by placing 15 g of cut tobacco sheets in a cylindrical container with an inner diameter of 60 mm and compressing the container with a load of 3 kg for 30 seconds to obtain the volume.

[Manufacturing method of tobacco sheet]
The tobacco sheet according to the present embodiment is produced by, for example, preparing a mixture containing a tobacco raw material, an aerosol-generating agent, a first molding agent, and a second molding agent, and 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 and imparting a corrugated shape. Note that the process of imparting a wave shape is also called a rippling process. For example, the tobacco sheet according to this embodiment can be produced by the following method.

A sheet cut into strips by a rotary roll blade is given a wavy shape and sawtooth shape as shown in FIG. In the case where the rolled product is not cut by a rotary roll blade, for example, by peeling off the rolled product on the rolling roller with a doctor knife, resistance is applied when peeled from the roll, and the wavy shape is also applied. and a sawtooth shape. In the case of producing a tobacco sheet by the above method, the surface of the pressure roller may be heated or cooled, and the number of revolutions of the pressure roller may be adjusted depending on the purpose. Furthermore, by adjusting the spacing between the rolling rollers, it is possible to obtain a tobacco sheet with a desired basis weight.

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

An example of the non-combustion heating type flavor inhaler according to this embodiment is shown in FIG. The non-combustion heating type flavor inhaler 4 shown in FIG. It comprises a segment 7 and a filter segment 8 . The non-combustion-heating flavor inhaler according to this embodiment may have segments other than the tobacco-containing segment, cooling segment, center hole segment, and filter segment.

The axial length of the non-combustion heating type flavor inhaler according to the present 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, 50 mm or more, It is more preferably 60 mm or less. The circumference of the non-combustion heating flavor inhaler 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, 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. In addition, the length of the filter segment can be selected within a range of 4 mm or more and 10 mm or less. Also, the ventilation resistance of the filter segments at that time is selected to be 15 mmH ₂ O/seg or more and 60 mmH ₂ O/seg or less per segment. These individual segment lengths can be changed as appropriate according to manufacturability, required quality, and the like. 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 be made to function as a non-combustion heating type flavor inhaler.

(segment containing tobacco)
In the tobacco-containing segment 5, the tobacco sheet according to the present embodiment is filled in wrapping paper (hereinafter also referred to as wrapper). The method of packing the tobacco sheet into the wrapping paper is not particularly limited. For example, the tobacco sheet may be wrapped in a wrapper, or the tobacco sheet may be packed in a cylindrical wrapper. When the shape of the tobacco sheet has a longitudinal direction such as a rectangular shape, the tobacco sheet may be packed so that the longitudinal direction is in an unspecified direction in the wrapper, and the tobacco-containing segment 5 may be packed in an axial direction or a longitudinal direction. They may be aligned and filled in a direction perpendicular to the axial direction.

(cooling segment)
As shown in FIG. 2, the cooling segment 6 may be configured by a cylindrical member 10. As shown in FIG. The tubular member 10 may be, for example, a paper tube formed by processing cardboard into a cylindrical shape.

The tubular member 10 and the mouthpiece lining paper 15, which will be described later, are provided with perforations 11 penetrating both. Due to the presence of the perforations 11 outside air is introduced into the cooling segment 6 during suction. As a result, the vaporized aerosol component generated by heating the tobacco-containing segment 5 comes into contact with the outside air, and its temperature decreases, liquefying to form an aerosol. The diameter (spanning length) of the perforations 11 is not particularly limited, but may be, for example, 0.5 mm or more and 1.5 mm or less. The number of perforations 11 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 11 may be provided on the circumference of the cooling segment 6 .

The amount of outside air introduced from the perforations 11 is preferably 85% by volume or less, more preferably 80% by volume or less, relative to the total volume of the gas inhaled by the user. When the ratio of the amount of outside air is 85% by volume or less, it is possible to sufficiently suppress reduction in flavor due to dilution by outside air. In other words, this is also called a ventilation ratio. From the viewpoint of cooling performance, the lower limit of the ventilation ratio range is preferably 55% by volume or more, more preferably 60% by volume or more.

The cooling segment may also be a segment comprising a crumpled, pleated, gathered or folded sheet of suitable construction material. The cross-sectional profile of such elements may exhibit randomly oriented channels. The cooling segment may also include a bundle of longitudinally extending tubes. Such cooling segments may be formed, for example, from pleated, gathered, or folded sheet material wrapped with wrapping paper.

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.

(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 wrapping 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 the function of increasing the strength of the mouthpiece segment 9 . The second filling layer 12 has an inner diameter of φ1.0 mm, for example, filled with cellulose acetate fibers at a high density and hardened by adding a plasticizer containing triacetin in an amount of 6% by mass or more and 20% by mass or less based on the mass of cellulose acetate. As described above, a rod having a diameter of 5.0 mm or less can be obtained. Since the second packed layer 12 has a high packing density of fibers, air and aerosol flow only through the hollow portion and hardly flow inside the second packed layer 12 during suction. Since the second filling layer 12 inside the center hole segment 7 is a fiber filling layer, the feeling of touch from the outside during use hardly causes the user to feel uncomfortable. Note that the center hole segment 7 may not have the second inner plug wrapper 13 and may retain its shape by thermoforming.

(filter segment)
Although the configuration of the filter segment 8 is not particularly limited, it may be composed of a single or a plurality of packed layers. The outer side of the packing layer may be wrapped with one or more wrapping papers. The ventilation resistance per segment of the filter segment 8 can be appropriately changed depending on the amount of filler, the material, etc. with which the filter segment 8 is filled. For example, when the filler is cellulose acetate fiber, increasing the amount of cellulose acetate fiber with which the filter segment 8 is filled can increase the ventilation resistance. When the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber can be 0.13-0.18 g/cm ³ . The airflow resistance is a value measured by an airflow resistance measuring instrument (trade name: SODIMAX, manufactured by SODIM).

Although the length of the circumference of the filter segment 8 is not particularly limited, it is preferably 16 to 25 mm, more preferably 20 to 24 mm, 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 from 15 to 60 mmH ₂ O/seg. The axial length of the filter segment 8 is preferably 5-9 mm, more preferably 6-8 mm. The cross-sectional shape of the filter segment 8 is not particularly limited, but may be, for example, circular, elliptical, polygonal, or the like. In addition, the filter segment 8 may be directly added with destructible capsules containing perfume, perfume beads, and perfume.

As shown in FIG. 2 , the center hole segment 7 and the filter segment 8 can be connected with an outer plug wrapper (outer wrapping paper) 14 . The outer plug wrapper 14 can be, for example, a cylinder of paper. Further, the tobacco-containing segment 5 , cooling segment 6 , connected center hole segment 7 and filter segment 8 can be connected by mouthpiece lining paper 15 . These connections can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 15, inserting the three segments, and winding them. In addition, these segments may be divided into multiple times and connected with multiple lining papers.

The heater 18 can be a heater based on electric resistance, and electric 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 emitted from the heater 18 is transmitted to the tobacco-containing segment of the non-combustion heating flavor inhaler 4 through the metal pipe 19 with high thermal conductivity.

In FIG. 3(b), there is a gap between the outer circumference of the non-combustion-heating flavor inhaler 4 and the inner circumference of the metal tube 19 because it is schematically illustrated. For the purpose of transmission, it is desirable that there is no gap between the outer circumference of the non-combustion heating flavor inhaler 4 and the inner circumference of the metal tube 19 . The heating device 16 heats the tobacco-containing segment of the non-combustion-heating flavor inhaler 4 from the outside, but it may heat the tobacco-containing segment from the inside.

Although the heating temperature of the heating device is not particularly limited, 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. The heating temperature indicates the temperature of the heater of the heating device.

In addition, non-combustion heating type flavor inhalers are required to reduce the sense of flavor inhibition (irritation) or discomfort. The sense of inhibition of flavor and taste means irritation to the oral cavity and throat upon inhalation. Hereinafter, a tobacco sheet for a non-combustion heating type flavor inhaler with reduced sense of inhibition of flavor and taste or discomfort will be described.

[First aspect]
In this aspect, the tobacco sheet for a non-combustion heating type flavor inhaler contains fructans. When the tobacco sheet is smoked, the fructans are thermally decomposed to generate a persistent sweet aroma. The persistent sweet aroma that is generated can continue from the early stage to the late stage of smoking behavior and suppress the feeling of inhibition of flavor and taste.

The above fructans are not particularly limited, but inulin-type fructans, levan-type fructans, branched fructans, fructooligosaccharides, or a combination of two or more of these can be used. Among these, inulin-type fructans are preferable from the viewpoint of cost reduction.

Although not bound by theory, it is presumed that the fructan of this embodiment has the following characteristics when it produces a sweet aroma through caramelization reaction.
Fructans are formed by binding multiple monosaccharides and have a larger molecular structure than monosaccharides and disaccharides. Therefore, when fructans undergo a caramelization reaction, they are decomposed into relatively small sugar molecules such as monosaccharides and disaccharides, and then these monosaccharides and disaccharides undergo a caramelization reaction to generate a sweet aroma. It is thought that it goes through a multi-stage decomposition process. On the other hand, when monosaccharides and disaccharides undergo a caramelization reaction, it is believed that these sugars undergo a caramelization reaction to directly generate a sweet aroma. Therefore, compared to monosaccharides and disaccharides, fructans are considered to be able to generate a sweet aroma at a slower rate due to the increased number of decomposition processes, and to generate a sweet aroma over a long period of time. In this embodiment, it is thought that the inhibition of flavor and taste can be suppressed continuously from the early stage to the late stage of smoking behavior due to such characteristics related to the caramelization reaction of fructans.

In some embodiments, the fructan content relative to 100% by mass of the tobacco sheet is not particularly limited, but is 0.1 to 5% by mass, 0.3 to 3.5% by mass, or 0.5 to 3% by mass. %. From the viewpoint of suppressing the feeling of inhibition of smoking and the persistence of suppression of the inhibition of smoking, the fructan content is preferably as high as possible. On the other hand, if the fructan content is too high, the flavor may be reduced. Therefore, from the viewpoint of suppressing the feeling of inhibition of smoking flavor and maintaining the flavor and flavor, the fructan content is 0.5 to 0.5. 3% by weight is preferred.

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.

<Tobacco leaves, aged tobacco leaves, and processed tobacco leaves>
“Tobacco leaves” is a general term for harvested tobacco leaves before undergoing ripening, which will be described later. One mode of aging includes curing. On the other hand, aged tobacco leaves before being processed into various forms used in tobacco products (such as cut tobacco, tobacco sheets, tobacco granules, etc.) are referred to as "aged tobacco leaves." ”. Furthermore, the aged tobacco leaves processed into various forms used in tobacco products are referred to as "processed tobacco leaves".

As a form of processed tobacco leaves used in tobacco products, for example, "cut tobacco" in which matured tobacco leaves are chopped into a predetermined size can be mentioned. Also, a "tobacco sheet" obtained by molding a composition containing matured tobacco leaves pulverized to a predetermined particle size (hereinafter also referred to as "tobacco fine powder") into a sheet shape, Mention may also be made of "tobacco granules" obtained by molding into granular form. The above-mentioned "tobacco powder" is also one form of processed tobacco leaves.

Non-tobacco materials include plant roots (including scales (bulbs), tuberous roots (potatoes), bulbs, etc.), stems, tubers, skins (including stem bark, bark, etc.), leaves, flowers (petals, pistils, etc.). , stamens, etc.), seeds, or tree trunks and branches.

The manufacturing method of tobacco sheets containing fructans is not limited. In some embodiments of the present application, it can be manufactured by preparing the tobacco sheets described above and supplying fructans from the outside. Specifically, it is preferable to supply fructans to the rolled product. The roll-formed article may be before or after being given the corrugated shape.

[Second aspect]
In this aspect, the tobacco sheet for a non-combustion heating type flavor inhaler contains a saturated fatty acid additive.
In this aspect, the tobacco sheet may contain materials derived from Orient species. In that case, the content of the material derived from the Orient species is preferably 10% by mass or less with respect to the tobacco raw material. When the content of the material derived from the Orient species is within this range, it is possible to provide a taste with less discomfort. From this point of view, 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.

The saturated fatty acid additive is selected from the group consisting of saturated fatty acids having a molar mass of 200-350 g/mol, esters of the saturated fatty acids, and combinations thereof. The saturated fatty acid reduces discomfort during smoking. Said esters of saturated fatty acids are obtained from alcohols and saturated fatty acids having a molar mass of 200 to 350 g/mol, so that the molar mass of the ester varies with the molar mass of the alcohol. The molar mass of the ester is in one embodiment from 210 to 1300 g/mol. Esters of saturated fatty acids generally have a lower vapor pressure than fatty acids, so that the effect of reducing discomfort during smoking is sustained throughout smoking. Hereinafter, the effect of reducing discomfort during smoking is also simply referred to as the effect of reducing discomfort.

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.

The content of the saturated fatty acid-based additive is 0.01 to 3% by mass based on the total dry matter mass of the tobacco raw material (assuming the dry matter content is 100% by mass). If the content is less than the lower limit, the effect of reducing discomfort is not sufficient, and if the content exceeds the upper limit, the offensive odor increases. From this point of view, 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 amount of dry substance is the mass excluding the medium described later, preferably the mass of the residue when the composition is dried at 100° C. for 5 hours.

The number of carbon atoms in the fatty acid portion of the saturated fatty acid and the ester is preferably 12-20, more preferably 15-19. When the number of carbon atoms is within this range, the effect of reducing discomfort becomes more pronounced.
The water solubility of the saturated fatty acid in the saturated fatty acid additive 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, preferably 0.05 mg/g or more.

Preferred specific examples of the saturated fatty acids include octanoic acid, decanoic acid, myristic acid, palmitic acid, stearic acid, and nonadecanoic acid. Among them, palmitic acid, stearic acid, or nonadecanic acid is preferable from the viewpoint of availability and expression of discomfort-reducing effect. Although the saturated fatty acid may be a mixture, it is preferably a single product rather than a mixture. In this embodiment, the single product (single compound) includes the case where the compound is a pure product, or the case where the compound contains impurities that are unavoidably contained. Thus, in one aspect the saturated fatty acids consist exclusively of palmitic acid. If the saturated fatty acid is a single product, the dispersibility of the saturated fatty acid in the molded article such as a sheet is improved when the tobacco composition of the present invention is formed into the molded article.

Preferable specific examples of the ester of saturated fatty acid (hereinafter also simply referred to as "ester") include the aforementioned alkyl ester and sugar ester of saturated fatty acid. 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 preferred said esters include sucrose palmitate and methyl palmitate. The saturated fatty acid moiety in the ester is preferably derived from a single saturated fatty acid for the reasons described above. Although the alcohol moiety in the ester does not have to be a single product, it is preferably a single product for the reason described above. The ester also functions as an emulsifier.

In one aspect, the saturated fatty acid additive contains the saturated fatty acid and the ester. In this case, there is an advantage that the effect of reducing discomfort can be maintained longer. Also, the type of saturated fatty acid additive can be appropriately selected depending on the tobacco raw material used. Therefore, this aspect also has the advantage of being versatile.

A part or all of the saturated fatty acid additive is preferably powder. When the saturated fatty acid-based additive is a powder, the dispersibility of the saturated fatty acid-based additive is improved in the molded article such as a sheet, as will be described later. Although its size is not limited, for example, D50 is preferably 30-120 μm, more preferably 50-100 μm. From the viewpoint of dispersibility, the saturated fatty acid additive preferably has a higher degree of crystallinity than wax or natural oils and fats.

The tobacco sheet may contain liquid sugar. Liquid sugar is liquid sugar. When the tobacco sheet contains liquid sugar, the feeling of sweetness is improved in addition to reducing discomfort during smoking. From this point of view, the liquid sugar content is preferably 3 to 10% by mass, more preferably 5 to 8% by mass, based on the amount of dry matter in the tobacco composition.

"Tobacco sheets may contain natural plant fragrances." When the tobacco sheet contains a natural vegetable flavor, in addition to the effect of reducing unpleasantness, the feeling of sweetness is improved. From this point of view, the content of the natural plant flavor is preferably 0.5 to 3% by mass, more preferably 2 to 3% by mass, based on the amount of dry matter in the tobacco composition. Natural botanical flavors that are known in the field of tobacco can be used, but licorice is preferred in the present invention. Licorice is a sweetener derived from Spanish licorice, which belongs to the genus Glycyrrhiza of the legume family.

The amount of nicotine contained in the tobacco sheet in this aspect is not limited, but in one aspect it can be 2% by mass or more based on the amount of dry matter in the tobacco sheet. In general, when the amount of nicotine increases, discomfort during smoking tends to increase. becomes more pronounced. Although the upper limit of the amount of nicotine is not limited, it is practically 3% by mass or less.

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

The tobacco sheet in this aspect can contain the aforementioned aerosol-generating agent. The amount of aerosol-generating agent is preferably 12% by weight or less, more preferably 11% by weight or less, based on the dry matter weight of the tobacco sheet. Moreover, the lower limit is not limited, and may be 0% by mass, preferably 1% by mass or more. If the amount of the aerosol-generating agent exceeds the upper limit, the production of the sheet may become difficult, and if it is less than the lower limit, the smoke sensitivity may decrease.

When the tobacco sheet contains a binder, the strength of the sheet is improved. A binder is an adhesive for binding fibers together. As the binder, those known in the art can be used. Binders include thickening polysaccharides such as gums, modified celluloses, and modified starches. The amount of the binder is appropriately adjusted depending on the application, and can be, for example, about 1 to 10% by mass based on the amount of dry matter of the tobacco sheet.

The tobacco sheet in this aspect is manufactured by any method. For example, when preparing the mixture, a saturated fatty acid-based additive is mixed to obtain a mixture containing the additive, and the sheet can be produced by the method described above. At that time, it is preferable to use a powdery saturated fatty acid-based additive and mix so as to maintain the powdery state. The tobacco sheet produced in this way has good dispersibility of the aerosol generating agent. Good dispersibility means that the saturated fatty acid additive is uniformly dispersed. The mixing step is preferably carried out below the melting point of the saturated fatty acid additive. For example, this step can be carried out at 10-50°C.

A mixture (also referred to as “slurry”) containing a saturated fatty acid-based additive 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 partly or entirely powdered, and a medium so as to maintain the powdery state to form a slurry.

In this method, the slurry is prepared while the saturated fatty acid-based additive remains powdery. By doing so, the dispersibility of the component (B) is improved when the molding is formed. The size of the powder is as described above. The fact that the saturated fatty acid additive maintains a powdery state means that part or all of it maintains a powdery state.

The medium includes water and hydrophilic organic solvents, but the most preferable medium for handling is water.

In this method, first, a material that is solid at room temperature is pulverized into powder, and these are mixed to obtain a powder mixture. On the other hand, liquid or pasty materials such as medium are mixed at room temperature to obtain a liquid mixture. Then, it is preferable to include a step of mixing the powder mixture and the liquid mixture.

The viscosity of the slurry at 25°C is preferably 100,000 to 200,000 (mPa·s) from the viewpoint of good dispersion of the powdery saturated fatty acid additive in the medium. The viscosity was measured using a Brookfield viscometer (Brookfield DV-I prime). Measured at 1.0 rpm using LV4.

The pancreatin solution is the supernatant obtained by adding 8 g of pancreatin to 100 ml of 0.1 M phosphate buffer of pH 6.4, stirring for 1 hour, and centrifuging at 8000 rpm for 30 minutes. The sample liquid is then transferred to a 15 ml centrifuge tube using ML-Q water and centrifuged at 8000 rpm for 15 minutes to remove the supernatant. This wash is repeated three times. After washing, 10 ml of a 5% sulfuric acid aqueous solution is added, and hydrolysis is performed at 100° C. for 2.5 hours. After the hydrolysis reaction is completed, the sample is allowed to cool to room temperature. The precipitate is then filtered off and the filtrate collected in a 250 ml volumetric flask. After thoroughly washing the residue on the filter paper with ML-Q water, the volume is adjusted to 250 ml. This solution is used as a sample for hemicellulose measurement. Transfer 500 μl of the 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.

Specific examples of the present embodiment will be described below, but the present invention is not limited to these.

[Example 1]
Tobacco lamina (leaf tobacco) was dry pulverized with a Hosokawa Micron ACM machine to obtain tobacco powder. For the tobacco powder, the cumulative 90% particle diameter (D90) in the volume-based particle size distribution measured by the dry laser diffraction method is measured using a Mastersizer (trade name, manufactured by Spectris Co., Ltd., Malvern Panalytical Division). As a result, it was 200 μm.

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

The swelling property of the obtained tobacco sheet was measured. Specifically, after leaving the tobacco sheet in a conditioned room at 22° C. and 60% for 48 hours, the swelling property was measured with DD-60A (trade name, manufactured by Borgwald). The measurement was carried out by placing 15 g of tobacco sheet in a cylindrical container with an inner diameter of 60 mm and compressing the container with a load of 3 kg for 30 seconds to obtain the volume. Table 1 shows the results. In addition, in Table 1, the swelling property is shown as an increase rate (%) of the swelling property with respect to the reference value of the swelling property value of Comparative Example 1 described later.

[Comparative Example 1]
A roll-formed product was produced in the same manner as in Example 1. After that, it was cut into strips with a plurality of ring-shaped rotary blades. Further, the tobacco sheet was cut to a length of 20 mm to obtain a tobacco sheet having a length of 20 mm and a width of 0.8 mm. The swelling property of the obtained tobacco sheet was measured in the same manner as in Example 1. Table 1 shows the results.

As can be seen from Table 1, the tobacco sheet of Example 1, which is the tobacco sheet according to the present embodiment, has improved swelling properties compared to the tobacco sheet of Comparative Example 1, which is not provided with a corrugated shape.

[Reference Example 1a]
1. Preparation of Smoking Composition Sheet A tobacco sheet (smoking composition sheet) manufactured by a known papermaking method was prepared. A wrapper was filled with the tobacco sheet to form a smoking segment, and a non-combustion heating type flavor inhalation article shown in FIG. 2 was prepared.

2. Preparation of fructan- or fructose-containing composition sheet for smoking Mixed solution of propylene glycol and water (propylene glycol: water = 1:9 (mass ratio)): 90 g of inulin-type fructan Name Fuji FF): 10 g was added and mixed to obtain an inulin-type fructan solution. And the above 1. A smoking composition sheet (containing an inulin-type fructan) after addition is prepared by adding a solution of inulin-type fructan using a syringe so as to spread over the entire tobacco sheet. Each sheet having an inulin-type fructan content of 0.5, 1.0, 2.0, 3.0, or 3.5% by mass was obtained.

In addition, 10 g of fructose (manufactured by Happo Shokusan Co., Ltd., product name: fructose) is added to 90 g of a mixture of propylene glycol and water (propylene glycol: water = 1:9 (mass ratio)). A solution of fructose was obtained by mixing. And the above 1. Prepare a similar tobacco sheet, and add a solution of fructose using a syringe so that it spreads throughout the tobacco sheet, so that the fructose for the entire smoking composition sheet (containing fructose) after addition Each sheet with a content of 0.5, 1.0, 2.0, 3.0, or 3.5% by weight was obtained.

A wrapper was filled with the fructan-containing smoking composition sheet or fructose-containing composition sheet obtained as described above to form a smoking segment, and the non-combustion heating type flavor inhalation article shown in FIG. 2 was prepared.

The above inulin-type fructan is one type of fructan, and smoking composition sheets containing inulin-type fructans correspond to examples of the present application. On the other hand, the fructose is one type of monosaccharide, and the smoking composition sheet containing fructose corresponds to the comparative example of the present application.

3. Evaluation of Flavor and Flavor Inhibition Feeling Each of the non-combustion heating flavor inhalation articles prepared as described in 1 or 2 above was installed in the non-combustion external heating smoking system shown in FIG.
Each flavor inhalation article prepared in this way was evaluated for flavor and flavor inhibition by 10 well-trained panelists. In the present Examples and Comparative Examples, the term "flavor" means a combined flavor of tobacco-derived flavor and inulin-type fructan or fructose-derived sweet flavor.
The evaluation of the flavor and flavor inhibition feeling of each smoking test roll was performed by each panelist's evaluation according to the 5-level criteria in Table 1a below, and the average value of the 10 panelists was calculated. In the criteria in Table 1a below, 3 is equivalent to a sheet that does not contain inulin-type fructans or fructose. Scores were calculated by rounding to the second decimal place when the average value had a value of two decimal places. Evaluation results are shown in Tables 2a and 3a and FIG.

As described above, smoking composition sheets containing inulin-type fructans correspond to examples of the present application, while smoking composition sheets containing fructose correspond to comparative examples of the present application.

From the results in Table 2a and Fig. 5, it was found that as the content of the inulin-type fructan increases, the numerical value of the sensation of flavor and taste inhibition decreases, and the sensation of flavor and taste inhibition can be suppressed. In particular, when the content of the inulin-type fructan is 3.0% by mass or more, the numerical value of the feeling of flavor and taste inhibition becomes 1, indicating that the feeling of flavor and taste inhibition can be suppressed extremely strongly. As described above, it was found that a higher content of inulin-type fructans is preferable from the viewpoint of suppressing the sense of inhibition of flavor and taste. On the other hand, it was found that as the content of inulin-type fructan increased, the flavor tended to decrease. When the flavor is emphasized, the value of the flavor is preferably 1.5 or more. Therefore, from the viewpoint of achieving both the flavor and the effect of suppressing the feeling of inhibition of the flavor, the content of the inulin-type fructan is 0.5 to 3% by mass. was found to be desirable.

On the other hand, from the results in Table 3a and Fig. 5, it was found that the addition of fructose also had the effect of suppressing the feeling of inhibition of flavor and taste to a certain extent. However, compared with the inulin-type fructans shown in Table 2a and FIG. 5, fructose was found to have a low and insufficient effect of suppressing the sense of flavor and taste inhibition.

Regarding fructose, a panelist commented that the feeling of inhibition of flavor and taste increases in the latter half of smoking (the effect of suppressing the feeling of inhibition of flavor and taste does not last long). A comparative experiment was carried out on the persistence of inhibitory effects on flavor and taste inhibition sensations of type fructans and fructose.

[Reference Example 2a]
1. Evaluation of Sustainability of Suppressing Effect of Inhibiting Flavor and Taste Inhibition A non-combustion-heating flavor inhalation article prepared in the same manner as in “2. Installed in a combustion externally heated smoking system.
For each flavor inhalation article thus prepared, 10 well-trained panelists evaluated the persistence of the effect of suppressing the sense of inhibition of flavor-smelling taste. For the evaluation of the persistence of the inhibitory effect on the flavor and taste inhibition of each smoking test volume, each panelist was asked to evaluate the effect of suppressing the flavor and taste inhibition until the second half of smoking and the absence of residual after smoking. Table 4a below. , and the average value of 10 panelists was calculated. Scores were calculated by rounding to the second decimal place when the average value had a value of two decimal places.
In the criteria of Table 4a below, when evaluating the persistence of the inhibitory effect on flavor and taste inhibition due to the difference in the content of the inulin-type fructan, 3 equivalent sheets were compared with a sheet containing 2.0% by mass of fructose. and In addition, when evaluating the persistence of the inhibitory effect on flavor and taste inhibition due to the difference in fructose content, 3 is equivalent to a sheet containing 2.0% by mass of inulin-type fructan.
Evaluation results are shown in Tables 5a and 6a and FIG.

From the results of Table 5a and FIG. 6, the inulin-type fructan suppresses the sensation of flavor and taste inhibition at any content of 0.5 to 3.5% by mass, compared to the 2.0% by mass fructose for comparison. It was found to be excellent in the durability of the effect.
In addition, from the results of Table 6a and FIG. 6, fructose, at any content of 0.5 to 3.5% by mass, compared to the 2.0% by mass inulin-type fructan for comparison, inhibited flavor and taste. It was found that the persistence of the anti-sensitivity effect was inferior.
Inulin-type fructans undergo a process of thermal decomposition before they develop a sweet flavor through a caramelization reaction, so it is thought that they slowly generate a sweet flavor over a long period of time. On the other hand, fructose is thought to generate a sweet flavor in a short period of time through a caramelization reaction. Since the sweet flavor suppresses the sense of inhibition of flavor-smelling taste, it is considered that the difference in duration of the effect of suppressing the sense of inhibition of flavor-drinking taste is caused by the difference in the generation time of the sweet flavor.
From the above results, it was confirmed that the inulin-type fructan is superior to fructose in the persistence of the inhibitory effect on flavor and taste inhibition.

From the above, it was found that the tobacco material of this example continuously suppresses the sense of flavor and taste inhibition from the early stage to the latter stage of smoking behavior (excellent persistence of the effect of suppressing the sense of flavor and taste inhibition).
