Abstract

The present invention relates to a tobacco sheet for a non-combustion heating type flavor inhaler, which comprises a tobacco powder having a 90% cumulative particle diameter (D90) of 200 [ mu ] m or more in a volume-based particle size distribution measured by a dry laser diffraction method.

Description

Tobacco sheet for non-combustion heating type flavor aspirator, and non-combustion heating type flavor aspiration system

Technical Field

The present invention relates to a tobacco sheet for a non-combustion heating type flavor inhaler, and a non-combustion heating type flavor inhaler system.

Background

In a combustion type flavor aspirator (cigarette), a tobacco filler including tobacco leaves is combusted to obtain flavor. As an alternative to this combustion type flavor aspirator, a non-combustion heating type flavor aspirator has been proposed in which a flavor source such as a tobacco sheet (tabaco sheet) is heated instead of being burned to obtain a flavor. The heating temperature of the non-combustion heating type flavor aspirator is lower than the combustion temperature of the combustion type flavor aspirator, for example, about 400 ℃ or lower. In this way, the heating temperature of the non-combustion heating type flavor aspirator is low, and therefore, from the viewpoint of increasing the smoke amount, an aerosol generating agent may be added to the flavor source in the non-combustion heating type flavor aspirator. The aerosol generating agent is vaporized by heating to generate an aerosol. The aerosol is supplied to the user together with flavor components such as tobacco components, and thus the user can obtain a sufficient flavor.

The non-combustion heating type flavor aspirator may include, for example, a tobacco-containing segment filled with a tobacco sheet or the like, a cooling segment, and a filter segment. The length of the tobacco-containing segment of the non-combustion heated flavor aspirator is generally shorter in axial direction than the length of the tobacco-containing segment of the combustion flavor aspirator, in relation to the heater. Therefore, if the flavor inhaler is a non-combustion heating type, the aerosol-generating amount during heating can be ensured, and therefore, a large number of tobacco sheets or the like are filled in a short section containing tobacco segments. In order to fill a large number of tobacco sheets or the like in a short section, a tobacco sheet having low bulk, i.e., a high density is generally used as a non-combustion heating type flavor aspirator. The bulk is a value indicating the volume of a tobacco sheet filament of a predetermined mass when compressed at a predetermined pressure for a predetermined time. For example, patent documents 1 and 2 disclose tobacco sheets used for non-combustion heating type flavor aspirators.

Disclosure of Invention

Problems to be solved by the invention

However, the present inventors have found that when considering the heating system, the heating capacity of the heater, and the aerosol generation, if a tobacco sheet having low bulk (high density) is used, the total heat capacity of the tobacco-containing segment becomes high, and depending on the heating method and the capacity of the heater, the tobacco sheet filled in the tobacco-containing segment cannot sufficiently contribute to the aerosol generation. To address this problem, it is contemplated to reduce the overall thermal capacity of the tobacco-containing segment.

The inventors have studied to reduce the total heat capacity of tobacco-containing segments: (1) reducing the specific heat of the tobacco raw material contained in the tobacco sheet; (2) use is made of highly bulky (low-density) tobacco sheets. However, regarding (1), it is difficult to reduce the specific heat of the tobacco raw material itself, and thus it can be considered that it is effective to reduce the total heat capacity of the tobacco-containing segment by (2). Accordingly, it is desired to develop a highly bulky (low density) tobacco sheet that can be suitably used for a non-combustion heated flavor aspirator.

The present invention aims to provide a tobacco sheet for a non-combustion heating type flavor inhaler with high bulk, a non-combustion heating type flavor aspirator comprising the tobacco sheet, and a non-combustion heating type flavor aspiration system.

Non-combustion heating type flavor aspirator

The non-combustion heating type flavor aspirator of the present embodiment includes a tobacco-containing segment including the tobacco sheet of the present embodiment and the like. Since the non-combustion heating type flavor aspirator of the present embodiment includes the tobacco-containing segment filled with the tobacco sheet having high bulk and the like of the present embodiment, the total heat capacity of the tobacco-containing segment can be sufficiently reduced, and the tobacco sheet filled with the tobacco-containing segment can be further facilitated in aerosol generation.

Fig. 1 shows an example of the non-combustion heating type flavor aspirator according to the present embodiment. The non-combustion heating type flavor aspirator 1 shown in fig. 1 includes: a tobacco-containing segment 2 filled with a tobacco sheet or the like of the present embodiment, a cylindrical cooling segment 3 having perforations 8 on the circumference, a center hole segment 4, and a filter segment 5. The non-combustion heating type flavor aspirator of 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.

The length in the axial direction of the non-combustion heating type flavor aspirator according to the present embodiment is not particularly limited, but is preferably 40mm to 90mm, more preferably 50mm to 75mm, still more preferably 50mm to 60 mm. The circumferential length of the non-combustion heating type flavor aspirator is preferably 16mm to 25mm, more preferably 20mm to 24mm, still more preferably 21mm to 23 mm. For example, the length of the tobacco-containing segment is 20mm, the length of the cooling segment is 20mm, the length of the center hole segment is 8mm, and the length of the filter segment is 7 mm. The length of the filter segment may be selected in a range of 4mm to 10 mm. In addition, the ventilation resistance of the filter segment at this time was set to 15mmH in each segment ₂ O/seg above and 60mmH ₂ O/seg is selected in the following manner. The length of each segment may be appropriately changed according to manufacturing suitability, required quality, and the like. Further, even if only the filter segment is disposed downstream of the cooling segment without using the center hole segment, it can be made to function as a non-combustion heating type flavor aspirator.

(tobacco-containing segment)

The tobacco-containing segment 2 is filled with a tobacco sheet or the like of the present embodiment in a roll paper (hereinafter also referred to as wrapping paper). The method of filling the roll paper (hereinafter also referred to as wrapping paper) with the tobacco sheet or the like is not particularly limited, and for example, the tobacco sheet or the like may be wrapped with the wrapping paper, or the cylindrical wrapping paper may be filled with the tobacco sheet or the like. When the shape of the tobacco sheet has a longitudinal direction like a rectangular shape, the tobacco sheet or the like may be filled so that the longitudinal direction thereof becomes an unspecified direction in the wrapping paper, or may be aligned in the axial direction of the tobacco-containing segment 2 or in a direction perpendicular to the axial direction.

(Cooling section)

As shown in fig. 1, the cooling section 3 is constituted by a tubular member 7. The tubular member 7 may be, for example, a paper tube obtained by processing thick paper into a cylindrical shape.

The tubular member 7 and a mouthpiece backing paper 12 described later are provided with perforations 8 penetrating both. By the presence of the perforations 8, external air is introduced into the cooling section 3 during suction. Thus, the aerosol-gasifying component produced by heating the tobacco-containing segment 2 is brought into contact with the outside air, and the temperature thereof is lowered to liquefy the aerosol-gasifying component, thereby forming an aerosol. The diameter (face-to-face length) of the through hole 8 is not particularly limited, and may be, for example, 0.5mm or more and 1.5mm or less. The number of the perforations 8 is not particularly limited, and may be 1 or 2 or more. For example, a plurality of perforations 8 may be provided on the circumference of the cooling section 3.

The amount of external air introduced from the through holes 8 is preferably 85% by volume or less, more preferably 80% by volume or less, relative to the volume of the whole air sucked by the user. By setting the ratio of the external air amount to 85% by volume or less, the reduction in flavor due to dilution with external air can be sufficiently suppressed. In the other words, the ventilation ratio is also referred to as "ventilation ratio". The lower limit of the range of the ventilation ratio is preferably 55% by volume or more, more preferably 60% by volume or more, from the viewpoint of cooling performance.

The cooling section may be a section containing a sheet of a suitably formed material which has been wrinkled, pleated, folded, or folded. The cross-sectional distribution of such elements sometimes shows randomly oriented channels. In addition, the cooling section may also comprise bundles of longitudinally extending tubes. Such a cooling section may be formed, for example, by wrapping pleated, gathered, or folded sheet material with roll paper.

The length of the cooling section in the axial direction may be, for example, 7mm or more and 28mm or less, and may be, for example, 18mm. The cooling section may have a substantially circular axial cross-sectional shape, and may have a diameter of, for example, 5mm or more and 10mm or less, for example, about 7mm.

(center hole section)

The center hole section is composed of a filler layer having one or more hollow portions, and an inner plug wrap (inner roll paper) covering the filler layer. For example, as shown in fig. 1, the central bore section 4 may be composed of a second filler layer 9 having a hollow portion, and a second inner plug wrap 10 covering the second filler layer 9. The central bore segment 4 has the function of increasing the strength of the mouth piece segment 6. The second filler layer 9 may be made into a rod having an inner diameter of 1.0mm or more and 5.0mm or less, which is filled with, for example, cellulose acetate fibers, added with a plasticizer containing triacetin and cured, wherein the amount of the plasticizer added is 6 mass% or more and 20 mass% or less with respect to the mass of cellulose acetate. Since the second filler layer 9 has a high packing density of fibers, air and aerosol flow only in the hollow portion during suction, and hardly flow in the second filler layer 9. Since the second filling layer 9 inside the center hole section 4 is a fiber filling layer, the feeling from the outside in use is less likely to cause a sense of incongruity to the user. The central hole section 4 may be formed by thermoforming without the second inner plug wrap 10.

(Filter tip segment)

The constitution of the filter segment 5 is not particularly limited, and may be constituted by a single or a plurality of filler layers. The outside of the filling layer may be wrapped by one or more rolls. The ventilation resistance of each of the filter segments 5 can be appropriately changed by the amount of filler, material, etc. filled in the filter segments 5. For example, in the case where the filler is cellulose acetate fiber, if the amount of cellulose acetate fiber filled in the filter segment 5 is increased, the ventilation resistance can be increased. In the case where the filler is cellulose acetate fiber, the cellulose acetate fiber may have a packing density of 0.13 to 0.18g/cm ³ . The air flow resistance was measured by an air flow resistance measuring instrument (trade name: manufactured by SODIMAX, SODIM).

The perimeter of the filter segment 5 is not particularly limited, but is preferably 16 to 25mm, more preferably 20 to 24mm, and even more preferably 21 to 23mm. The axial length of the filter segments 5 can be chosen to be 4-10 mm to provide ventilation resistanceReaching 15 to 60mmH ₂ O/seg mode selection. The axial length of the filter segments 5 is preferably 5 to 9mm, more preferably 6 to 8mm. The cross-sectional shape of the filter segment 5 is not particularly limited, and may be circular, elliptical, polygonal, or the like, for example. In addition, destructive capsules containing flavourant, flavourant beads, flavourant may be added directly to the filter segment 5.

As shown in fig. 1, the central bore section 4 and the filter section 5 may be connected by an outer plug wrap (outer plug wrap) 11. The outer plug wrap 11 may be, for example, cylindrical paper. In addition, the tobacco-containing segment 2, cooling segment 3, attached central bore segment 4, and filter segment 5 may be attached by a tipping paper 12. These connections can be made by applying a paste such as vinyl acetate paste to the inner surface of the tipping paper 12, placing the 3 segments, and winding them. The segments may be connected by a plurality of interleaving papers.

[ non-Combustion heating type fragrance suction System ]

The non-combustion heating type flavor pumping system according to the present embodiment includes: the non-combustion heating type flavor aspirator of the present embodiment and the heating device for heating the tobacco-containing segment of the non-combustion heating type flavor aspirator. The non-combustion heating type flavor-absorbing system of the present embodiment may have other configurations in addition to the non-combustion heating type flavor-absorbing device of the present embodiment and the heating device.

Fig. 2 shows an example of the non-combustion heating type fragrance pumping system according to the present embodiment. The non-combustion heating type fragrance sucking system shown in fig. 2 includes: the non-combustion heating type flavor aspirator 1 of the present embodiment, and the heating device 13 for heating the tobacco-containing segment of the non-combustion heating type flavor aspirator 1 from the outside.

Fig. 2 (a) shows a state before the non-combustion heating type flavor aspirator 1 is inserted into the heating device 13, and fig. 2 (b) shows a state in which the non-combustion heating type flavor aspirator 1 is inserted into the heating device 13 and heated. The heating device 13 shown in fig. 2 includes: a body 14, a heater 15, a metal tube 16, a battery unit 17, and a control unit 18. The main body 14 has a cylindrical recess 19, and the heater 15 and the metal tube 16 are disposed at positions corresponding to tobacco-containing segments of the non-combustion heating type flavor aspirator 1 to be inserted into the recess 19 on the inner side surface of the recess 19. The heater 15 may be a heater using electric resistance, and the electric power is supplied from the battery unit 17 in accordance with an instruction from the control unit 18 that performs temperature control, thereby performing heating of the heater 15. The heat emitted by the heater 15 is transferred to the tobacco-containing section of the non-combustion heated flavor aspirator 1 through the metal tube 16 having a high thermal conductivity.

In fig. 2 (b), a gap is schematically illustrated between the outer periphery of the non-combustion heating type flavor aspirator 1 and the inner periphery of the metal tube 16, but in practice, for the purpose of efficiently transferring heat, it is more preferable that there is no gap between the outer periphery of the non-combustion heating type flavor aspirator 1 and the inner periphery of the metal tube 16. The heating device 13 heats the tobacco-containing segment of the non-combustion heating type flavor aspirator 1 from the outside, but may be a device that heats the tobacco-containing segment from the inside.

The heating temperature by the heating device is not particularly limited, but is preferably 400 ℃ or lower, more preferably 150 ℃ or higher and 400 ℃ or lower, and further preferably 200 ℃ or higher and 350 ℃ or lower. The heating temperature means the temperature of the heater of the heating device.

Further, for the non-combustion heating type flavor aspirator, reduction of the odor blocking feeling (stimulus) or the uncomfortable feeling is also demanded. The smell blocking sensation refers to the irritation of the mouth and throat during inhalation. Hereinafter, a tobacco sheet for a non-combustion heating type flavor inhaler with reduced odor blocking or uncomfortable feeling will be described.

[ mode 1 ]

In this embodiment, the tobacco sheet for a non-combustion heating type flavor inhaler contains levan. If the tobacco sheet is supplied for smoking, levan undergoes thermal decomposition to continuously produce sweet aroma. The produced sweet flavor can continuously inhibit the odor blocking sensation from the initial stage to the later stage of smoking action.

The Levan is not particularly limited, and inulin-type Levan, branched Levan, fructooligosaccharide, or a combination of two or more thereof may be used. Among these, inulin-type levan is preferred from the viewpoint of cost reduction.

Without being bound by theory, it is postulated that the fructans of the present embodiment have the following characteristics when they produce a sweet aroma by the caramelization reaction.

Levan is formed by combining a plurality of monosaccharides and has a molecular structure larger than that of monosaccharides and disaccharides. Therefore, it is considered that when the caramelization reaction of levan occurs, the following decomposition steps are performed: after decomposition into smaller molecular saccharides such as monosaccharides and disaccharides, these monosaccharides and disaccharides undergo caramelization reaction to produce sweet aroma. On the other hand, when the caramelization reaction occurs in the monosaccharides and disaccharides, the caramelization reaction occurs in these sugars, and it is considered that sweet aroma is directly generated. Therefore, it is considered that levan produces sweet aroma at a slower rate corresponding to a larger number of decomposition steps than monosaccharides and disaccharides, and sweet aroma is produced for a longer period of time. In this embodiment, it is considered that the characteristic relating to the caramelization reaction of levan can be used to continuously suppress the odor blocking sensation from the initial stage to the later stage of smoking action.

In several embodiments, the content of levan relative to the tobacco powder is not particularly limited, and may be set to 0.1 to 5 mass%, 0.3 to 3.5 mass%, or 0.5 to 3 mass%. From the viewpoint of suppressing the odor blocking feeling and the persistence of the odor blocking feeling, the case where the content of levan is large is preferable. On the other hand, if the levan content is too large, the flavor may be reduced, and therefore, the levan content is preferably 0.5 to 3 mass% from the viewpoint of both the suppression of the odor-resistant feeling and the persistence thereof and the odor.

In this embodiment, the raw material of the tobacco powder may further include tobacco leaf, cured tobacco leaf, processed tobacco leaf, tobacco filler, non-tobacco material, or a combination of two or more thereof.

Tobacco leaf, cured tobacco leaf and processed tobacco leaf

"tobacco leaf" refers to the collective term for the materials of the leaves of harvested tobacco prior to curing as described below. One embodiment of curing includes baking. In contrast, tobacco leaves after curing and before being processed into various forms (cut tobacco, tobacco pieces, tobacco particles, etc., described later) that are utilized as tobacco products are referred to as "cured tobacco leaves". In addition, tobacco leaves after cured tobacco leaves are processed into various forms that are utilized as tobacco products are called "processed tobacco leaves".

Examples of the form of the processed tobacco leaves used as the tobacco product include: the cured tobacco leaves are cut into cut tobacco of a given size. In addition, there may be mentioned: a composition comprising a fine powder obtained by pulverizing cured tobacco leaves so as to have a predetermined particle diameter (hereinafter, also referred to as "tobacco fine powder") is formed into a sheet-shaped "tobacco sheet", and "tobacco particles" obtained by forming into a particle shape. The "tobacco fine powder" is also one mode of processed tobacco leaves.

Examples of the non-tobacco material include: roots (including scales (bulbs), tubers (tubers), bulbs, etc.), stems, tubers, barks (including stem barks, bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), or seeds, or stems, branches, etc. of trees.

The method for producing the tobacco sheet containing levan is not limited. In several embodiments of the present application, it may be manufactured by preparing the above-described tobacco sheet and supplying levan from the outside.

[ mode 2 ]

In this embodiment, the tobacco sheet for a non-combustion heating type flavor inhaler contains a saturated fatty acid additive.

In this embodiment, the tobacco sheet may comprise a material derived from Oriental tobacco species. In this case, the content of the oriental tobacco seed-derived material is preferably 10 mass% or less relative to the tobacco powder. When the content of the oriental tobacco seed-derived material is within this range, a taste with further reduced discomfort can be provided. From this viewpoint, the upper limit of the content is preferably 8 mass% or less, more preferably 5 mass% or less. The lower limit thereof is preferably 0.1 mass% or more, more preferably 2 mass% or more, and still more preferably 3 mass% or more.

The saturated fatty acid additive is selected from saturated fatty acids having a molar mass of 200-350 g/mol, esters of the saturated fatty acids, and combinations thereof. The saturated fatty acids can reduce discomfort during smoking. The ester of a saturated fatty acid is obtained from an alcohol and a saturated fatty acid having a molar mass of 200 to 350g/mol, and therefore the molar mass of the ester varies depending on the molar mass of the alcohol. In one embodiment, the ester has a molar mass of 210 to 1300g/mol. The saturated fatty acid esters generally have a lower vapor pressure than fatty acids, and therefore, the effect of reducing discomfort during smoking is sustained throughout the smoking process. Hereinafter, the effect of reducing the uncomfortable feeling upon smoking will also be simply referred to as an uncomfortable feeling reducing effect.

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

The saturated fatty acid additive is contained in an amount of 0.01 to 3 mass% relative to the total mass of the dry matters of the tobacco powder (the dry matter amount is 100 mass%). If the content is less than the lower limit, the effect of reducing the uncomfortable feeling is insufficient, and if it exceeds the upper limit, the feeling of strangeness increases. From this viewpoint, the lower limit of the content is preferably 1 mass% or more, and the upper limit thereof is preferably 2 mass% or less. The dry mass means a mass other than the medium described later, and is preferably a mass of the residue when the composition is dried at 100 ℃ for 5 hours.

The number of carbon atoms in the fatty acid part of the saturated fatty acid is preferably 12 to 20, more preferably 15 to 19. If the number of carbon atoms is within this range, the effect of reducing the discomfort becomes more remarkable.

The solubility of the saturated fatty acid in the saturated fatty acid additive in water is preferably 0.15mg/g or less, more preferably 0.12mg/g or less. The lower limit is not limited, but may be 0mg/g, but is preferably 0.05mg/g or more.

Preferable specific examples of the saturated fatty acid include: caprylic acid, capric acid, myristic acid, palmitic acid, stearic acid, and nonadecanoic acid. Among them, palmitic acid, stearic acid, or nonadecanoic acid is preferable from the viewpoint of easy acquisition and showing of the effect of reducing discomfort. The saturated fatty acids may also be mixtures, but are preferably not individual products of the mixture. In this embodiment, a single product (single compound) includes a case where the compound is a pure product or a case where the compound contains an impurity which is inevitably contained. Thus, in one embodiment, the saturated fatty acids consist of only palmitic acid. When the saturated fatty acid is used as a single product, the dispersibility of the saturated fatty acid in a molded article such as a sheet is improved when the tobacco composition of the present invention is produced into the molded article.

Preferable specific examples of the esters of saturated fatty acids (hereinafter, also simply referred to as "esters") include alkyl esters and sugar esters of saturated fatty acids. The alkyl moiety is preferably a linear, branched or cyclic alkyl group having 1 to 10 carbon atoms such as a methyl group. The sugar moiety is preferably derived from disaccharides such as sucrose. Preferable examples of the above-mentioned esters include sucrose palmitate and methyl palmitate. The saturated fatty acid moiety in the ester is preferably a saturated fatty acid derived from a single product for the reasons described above. The alcohol site in the ester is not necessarily a single product, but is preferably a single product for the reasons described above. The above esters also function as emulsifiers.

In one embodiment, the saturated fatty acid additive comprises the saturated fatty acid and the ester. In this case, there is an advantage that the effect of reducing discomfort can be further continued. The type of the saturated fatty acid additive may be appropriately selected according to the tobacco raw material and the like used. This embodiment also has the advantage of versatility.

Preferably, part or all of the saturated fatty acid additive is in the form of a powder. If the saturated fatty acid additive is a powder, the dispersibility of the saturated fatty acid additive in a molded body such as a tablet is improved when the molded body is produced as described later. The size is not limited, and for example, D50 is preferably 30 to 120. Mu.m, more preferably 50 to 100. Mu.m. In addition, from the viewpoint of the dispersibility, the saturated fatty acid-based additive preferably has a higher crystallinity than waxes or natural oils.

The tobacco sheet may also contain liquid sugar. Liquid sugar refers to sugar in liquid form. If the tobacco sheet contains liquid sugar, the sweetness is improved in addition to the reduction of the uncomfortable feeling upon smoking. From this viewpoint, the content of the liquid sugar is preferably 3 to 10% by mass, more preferably 5 to 8% by mass, relative to the dry matter in the tobacco composition.

The tobacco sheet may comprise natural botanical flavors. If the tobacco sheet contains natural plant flavor, the sweetness is improved in addition to the effect of reducing discomfort. From this viewpoint, the content of the natural plant flavor is preferably 0.5 to 3% by mass, more preferably 2 to 3% by mass, relative to the dry matter in the tobacco composition. As the natural plant flavor, natural plant flavors known in the tobacco field can be used, and in the present invention, licorice is preferable. Licorice is a sweetener derived from Spanish licorice, which is a genus of Glycyrrhiza in the family Leguminosae.

The amount of nicotine contained in the tobacco sheet in the present embodiment is not limited, and in one embodiment, the amount may be 2 mass% or more with respect to the dry matter of the tobacco sheet. In general, if the amount of nicotine increases, the uncomfortable feeling during smoking tends to increase, but in this embodiment, the uncomfortable feeling reducing effect is exerted as described above, and therefore, when the amount of nicotine is in the above range, the effect of this embodiment becomes more remarkable. The upper limit of the amount of nicotine is not limited, but is 3 mass% or less in reality.

In another embodiment, the amount of nicotine may be 1.5% by mass or less. If the amount of nicotine is within the above range, a mild flavor can be imparted. The lower limit of the amount of nicotine is not limited, but is practically 0.1 mass% or more. The nicotine contained in the tobacco sheet may be derived from the above-mentioned tobacco powder or other components.

The tobacco sheet according to the present embodiment may contain the aerosol generating agent described above. The amount of the aerosol generating agent is preferably 12 mass% or less, more preferably 11 mass% or less, relative to the dry mass of the tobacco sheet. The lower limit is not limited, but may be 0 mass% or more, and preferably 1 mass% or more. If the amount of the aerosol generating agent exceeds the upper limit value, there is a risk that the production of the sheet becomes difficult, and if it is less than the lower limit value, there is a risk that the smoke feeling is reduced.

If the tobacco sheet contains a binder, the strength of the sheet is increased. The binder is an adhesive for bonding fibers to each other and the like. As the binder, a binder known in the art may be used. Examples of the binder include thickening polysaccharides such as gums (gum), modified celluloses and modified starches. The amount of the binder may be appropriately adjusted depending on the application, and may be, for example, about 1 to 10 mass% relative to the dry mass of the tobacco sheet.

The tobacco sheet according to this embodiment can be produced by any method. For example, in the preparation of the above mixture, a saturated fatty acid-based additive may be mixed to prepare a mixture containing the additive, and a tablet may be produced by the above method using the mixture. In this case, it is preferable to use a powdered saturated fatty acid additive and mix the components so as to maintain the powdered state. The aerosol generating agent in the tobacco sheet thus produced has good dispersibility. Good dispersibility means that the saturated fatty acid additive is uniformly dispersed. The mixing step is preferably performed at a temperature not higher than the melting point of the saturated fatty acid additive. For example, the step may be carried out at 10 to 50 ℃.

The mixture (also referred to as "slurry") containing the saturated fatty acid additive is preferably produced by a method including the following steps.

And mixing the tobacco material or fibrous tobacco material, a saturated fatty acid additive partially or completely in powder form, and a medium so as to maintain the powder in a powder state, thereby preparing a slurry.

In this method, a slurry is prepared with the saturated fatty acid-based additive maintained in a powder state. In this way, the dispersibility of the component (B) is improved when the molded article is produced. The dimensions of the powder are as described above. The saturated fatty acid-based additive remains in a powder state, meaning that some or all of it remains in a powder state.

As the medium, water and a hydrophilic organic solvent are exemplified, and the most preferable medium from the aspect of handling is water.

In the present method, solid materials are first powdered by pulverization or the like at room temperature, and they are mixed to obtain a powder mixture. On the other hand, materials such as a medium which is liquid or pasty at room temperature are mixed to obtain a liquid mixture. Further, it is preferable to include a step of mixing the powder mixture with the liquid mixture.

From the viewpoint of well dispersing the powdery saturated fatty acid-based additive in the medium, the viscosity of the slurry at 25 ℃ is preferably 100000 ～ 200000 (mpa·s). The viscosity can be measured using a type B viscometer (DV-I prime manufactured by Brookfield) and using spindle No. LV4 at 1.0 rpm.

[ mode 3 ]

In this embodiment, the tobacco-containing segment (hereinafter, also simply referred to as "tobacco segment") includes paper, or paper containing an aerosol generating agent. An outline of the tobacco segment in this embodiment is shown in fig. 3A. The tobacco segment 20A includes a tobacco filler 21 and a wrapping paper 22 wrapped around the tobacco filler. The tobacco filler 21 comprises the tobacco sheet T and paper P described above. In the drawing, the tobacco sheet T is cut into a strand shape, and the paper P is also cut into a strand shape. The strand may be a material obtained by cutting a sheet obtained by stacking tobacco sheets T and paper P.

Fig. 3B shows a manner in which the sheet-like tobacco filler 21 is swirlly filled in the wrapping paper 22. The sheet-shaped tobacco filler 21 may be a sheet obtained by stacking the tobacco sheet T and the paper P, or may be a sheet obtained by joining the side surfaces of the tobacco sheet T and the paper P to each other or to the vicinity of the side surfaces.

Fig. 3C shows a manner in which the sheet-like tobacco filler 21 is folded and filled in the wrapping paper 22. The sheet-shaped tobacco filler 21 may be a sheet obtained by stacking the tobacco sheet T and the paper P, or may be a sheet obtained by joining the side surfaces of the tobacco sheet T and the paper P to each other or to the vicinity of the side surfaces.

Fig. 3D shows a manner of filling the wrapping paper 22 with the thread-like tobacco filler 21. In this figure, a mode is shown in which the thread and the thread paper P obtained from the tobacco sheet T are prepared and filled, respectively. The thread is a material obtained by cutting a sheet formed by stacking tobacco sheets T and paper P.

Fig. 3E shows a manner in which the sheet-like tobacco filler 21 is compressed into a mass from the longitudinal and transverse directions and is filled in the wrapping paper 22. The sheet-shaped tobacco filler 21 may be a sheet obtained by stacking the tobacco sheet T and the paper P, or may be a sheet obtained by joining the side surfaces of the tobacco sheet T and the paper P to each other or to the vicinity of the side surfaces.

As the 3-1 rd aspect, the tobacco segment comprises a tobacco sheet and paper having a total content of lignin and hemicellulose of 0.1 to 10 mass% as a filler. The filler is used for tobacco segments. Lignin refers to a high molecular phenol compound contained in trees and the like. Hemicellulose refers to insoluble polysaccharides contained in the cell wall. If the total amount is within this range, the unpleasant smell (such as fibrous smell) during smoking can be reduced. That is, in this embodiment, the effect of diluting the original flavor can be exhibited without significantly impeding the original flavor. From this viewpoint, the upper limit of the total content of lignin and hemicellulose is preferably 9.0 mass% or less.

Next, the sample liquid was transferred to a 15ML centrifuge tube using ML-Q water, and centrifuged at 8000rpm for 15 minutes to remove the supernatant. The washing was repeated three times. After washing, 10ml of a 5% aqueous sulfuric acid solution was added, and hydrolysis was performed at 100℃for 2.5 hours. After the hydrolysis reaction, the sample was naturally cooled to room temperature. Next, the precipitate was filtered, and the filtrate was recovered into a 250ml pear-shaped flask. After the residue on the filter paper was sufficiently washed with ML-Q water, the volume was set to 250ML. The solution was used as a sample for hemicellulose measurement. The sample was transferred to a 20ml test tube by 500. Mu.l, and 500.

The paper used in the present embodiment may contain or may not contain an aerosol generating agent described later. The amount may be in the range described in the 3-2 th aspect or may be other than the above.

(1-2) mode 3-2

As the 3 rd to 2 nd modes, the tobacco segment contains a tobacco sheet and a paper containing an aerosol generating agent as a filler. The aerosol generating agent is a material that generates an aerosol by heating and vaporizing and cooling, or generates an aerosol by atomizing. In this embodiment, since the paper containing the aerosol generating agent is used, the effect of diluting the flavor and taste without reducing the smoke amount can be exhibited. As the aerosol generating agent, the aerosol generating agents described above can be used. The amount of the aerosol generating agent is preferably 3 to 20% by mass, more preferably 5 to 15% by mass, based on the dry matter of the paper. If the amount of the aerosol generating agent exceeds the upper limit, dirt or the like may be generated in the tobacco segment, and if the amount is less than the lower limit, there is a risk that the smoke feeling is reduced.

In a preferred embodiment, the paper has the same shape as the tobacco sheet, and in a most preferred embodiment, the filaments of the paper and the filaments of the tobacco sheet are used.

In addition, a perfume or the like generally used in the art, such as menthol, may be added to the paper.

Examples

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

Example 1

Tobacco leaves (tobacco leaves) were dry-pulverized by a Hosokawa Micron ACM machine to obtain tobacco powder. The cumulative particle size of 50% (D50) and the cumulative particle size of 90% (D90) in the particle size distribution based on the volume by dry laser diffraction method were measured using a Mastersizer (trade name, manufactured by Spectis Co., ltd. Malvern Panalytical, inc.), and the results were 57 μm and 216 μm, respectively.

Using the above tobacco powder, a tobacco sheet was produced by a rolling method. Specifically, 87 parts by mass of the tobacco powder, 12 parts by mass of glycerin as an aerosol generating agent, and 1 part by mass of carboxymethyl cellulose as a molding agent were mixed and kneaded by an extrusion molding machine. The kneaded material was formed into a sheet shape by using two pairs of metal rolls, and dried in a heated air circulation oven at 80 ℃. The tobacco sheet was shredded by a shredder to dimensions of 0.8mm by 9.5 mm.

The bulk of the cut tobacco pieces was measured. Specifically, the cut tobacco sheet was stored in a 60% tempering room at 22℃for 48 hours, and then the bulk was measured by DD-60A (trade name, manufactured by Borgward Co., ltd.). The measurement was performed by adding 15g of the cut tobacco pieces to a cylindrical container having an inner diameter of 60mm, and obtaining the volume when compressed for 30 seconds under a load of 3 kg. The results are shown in Table 1. In table 1, the bulk is shown by the rate (%) of increase in bulk with respect to a reference value, based on the value of bulk of comparative example 1 described later.

Example 2

Tobacco sheets were produced and evaluated in the same manner as in example 1, except that tobacco powders having 50% cumulative particle diameters (D50) and 90% cumulative particle diameters (D90) of 121 μm and 389 μm, respectively, in a volume-based particle diameter distribution by a dry laser diffraction method were used as the tobacco powders. The results are shown in Table 1.

Example 3

Tobacco sheets were produced and evaluated in the same manner as in example 1, except that tobacco powders having a 50% cumulative particle diameter (D50) and a 90% cumulative particle diameter (D90) of 225 μm and 623 μm, respectively, in a volume-based particle diameter distribution by a dry laser diffraction method were used as the tobacco powders. The results are shown in Table 1.

Comparative example 1

Tobacco sheets were produced and evaluated in the same manner as in example 1, except that tobacco powders having 50% cumulative particle diameters (D50) and 90% cumulative particle diameters (D90) of 32 μm and 84 μm, respectively, in a volume-based particle diameter distribution by a dry laser diffraction method were used as the tobacco powders. The results are shown in Table 1.

TABLE 1

D3, 2 average diameter of surface area (load)

D [4,3] volume (load) average diameter

According to table 1, the tobacco sheets of examples 1 to 3, which are the tobacco sheets of the present embodiment, were improved in bulk as compared with the tobacco sheet of comparative example 1 in which the D90 of the tobacco powder was less than 200 μm as measured by the dry laser diffraction method. In examples 1 to 3, tobacco sheets were produced by a rolling method, but when tobacco sheets were produced by a casting method in the same manner, the bulk was also improved.

Reference example 1a

1. Preparation of smoking composition tablet

Tobacco sheets (smoking composition sheets) produced by a known paper-making method were prepared. The tobacco sheet was packed in a wrapping paper to prepare a smoking segment, and a non-combustion heating type flavor aspirator shown in fig. 1 was prepared.

2. Preparation of a tablet of smoking composition containing levan or fructose

To a mixture of propylene glycol and water (propylene glycol: water=1:9 (mass ratio)) was added 90g of inulin (FujiFF, product name of Fuji Nihon Seito corporation) 10g of inulin and mixed, whereby a solution of inulin was obtained. Then, a tobacco sheet similar to the tobacco sheet 1 described above was prepared, and a solution of inulin-type levan was added to the whole tobacco sheet using a syringe, whereby respective sheets having a content of inulin-type levan of 0.5, 1.0, 2.0, 3.0, or 3.5 mass% relative to the whole smoking composition sheet (containing inulin-type levan) after the addition were obtained.

Further, 90g of a mixed solution of propylene glycol and water (propylene glycol: water=1:9 (mass ratio)) was added to 10g of fructose (product name: fructose manufactured by eight-treasure co., ltd.) and mixed to obtain a fructose solution. Then, a solution of fructose was added to the tobacco sheet as in the above 1 using a syringe so as to cover the entire tobacco sheet, whereby respective sheets having a fructose content of 0.5, 1.0, 2.0, 3.0, or 3.5 mass% relative to the entire added (fructose-containing) smoking composition sheet were obtained.

The fructan-containing smoking composition sheet or fructose-containing smoking composition sheet obtained as described above was filled into a wrapping paper to prepare a smoking segment, and a non-combustion heated flavor aspirator shown in fig. 1 was prepared.

The inulin-type levan is one of levan, and a smoking composition tablet containing inulin-type levan corresponds to an embodiment of the present application. On the other hand, the fructose is one of monosaccharides, and a tablet of the fructose-containing smoking composition corresponds to a comparative example of the present application.

3. Evaluation of smell and smell blocking feeling

Each of the non-combustion heating type flavor aspirators prepared as described in 1 or 2 above was installed in a non-combustion external heating type smoking system shown in fig. 3.

For each of the thus prepared flavor aspirators, the flavor and the odor blocking feeling were evaluated by an evaluation group of 10 persons who had been sufficiently trained. In the present examples and comparative examples, "flavor" means flavor obtained by combining flavor derived from tobacco and sweet flavor derived from inulin-type fructan or fructose.

The flavor and the flavor blocking feeling of each smoking test roll were evaluated by each evaluation group based on the 5-level standard in table 1a, and the average value of the 10-person evaluation group was calculated. In the reference of table 1 below, the case equivalent to that of a tablet containing no inulin-type levan or fructose was set to 3. In the case where the average value has a value of the 2 nd bit after the decimal point, the score is calculated by rounding the 2 nd bit after the decimal point. The evaluation results are shown in tables 2a and 3a and fig. 4.

TABLE 1a

	Greatly reduce	Reduction of	Unchanged	Increase in	Greatly increase
						Fragrance of Chinese medicine	1	2	3	4	5
Smell absorption and blocking sense	1	2	3	4	5

As described above, the inulin-containing levan-containing smoking composition sheet corresponds to the example of the present application, while the fructose-containing smoking composition sheet corresponds to the comparative example of the present application.

From the results shown in table 2a and fig. 4, it was found that the value of the odor blocking sensation was decreased as the content of inulin-type levan was increased, and the odor blocking sensation was suppressed. In particular, it is found that when the content of inulin-type levan is 3.0 mass% or more, the value of the odor blocking sensation becomes 1, and the odor blocking sensation can be extremely strongly suppressed. Thus, it is found that inulin-type levan is more preferable in terms of suppressing the odor-inhibiting effect. On the other hand, it is found that the flavor tends to be lowered as the content of inulin-type levan increases. It is found that, when the flavor is emphasized, the value of the flavor is preferably 1.5 or more, and therefore, the content of inulin-type levan is preferably 0.5 to 3% by mass from the viewpoint of the effect of suppressing both flavor and flavor-absorbing resistance.

On the other hand, as is clear from the results of table 3a and fig. 4, the addition of fructose also has a certain effect of suppressing the odor inhibition. However, it was found that fructose was less effective in suppressing the odor-blocking sensation than inulin-like fructan shown in Table 2a and FIG. 4, and was insufficient.

Further, regarding fructose, the evaluation group showed a comment that the flavor-blocking sensation was half-increased after smoking (the effect of suppressing the flavor-blocking sensation did not last for a long time), and therefore, as shown in reference example 2a below, a comparative experiment was performed on the persistence of the flavor-blocking sensation suppressing effect with respect to inulin-type fructosan and fructose.

Reference example 2a

1. Evaluation of persistence of inhibition effect of odor-absorbing inhibition effect

The non-combustion heating type flavor aspirator prepared in the same manner as in "2. Preparation of a fructan or fructose-containing smoking composition sheet" of reference example 1a was installed in the non-combustion external heating type smoking system shown in fig. 3.

For each of the thus prepared flavor aspirators, the flavor-absorbing sensation-suppressing effect persistence was evaluated by an evaluation group of 10 persons who had been sufficiently trained. The evaluation of the duration of the flavor-blocking effect of each smoking test roll was performed as follows: for the effect of suppressing the odor blocking sensation until the second half of smoking and no post-residual odor blocking sensation after smoking, each evaluation group was evaluated based on the 5-level standard of table 4a below, and the average value of the 10-person evaluation group was calculated. In the case where the average value has a value of the 2 nd bit after the decimal point, the score is calculated by rounding the 2 nd bit after the decimal point.

In the reference of table 4a below, when the flavor-blocking sensation suppressing effect persistence caused by the difference in the content of inulin-type fructan was evaluated, the case equivalent to that of a tablet containing 2.0 mass% fructose was set to 3. In the case of evaluating the persistence of the effect of suppressing the odor-suppressing effect due to the difference in the content of fructose, the case equivalent to that of a sheet containing 2.0 mass% of inulin-type levan was set to 3.

The evaluation results are shown in tables 5a and 6a and fig. 5.

TABLE 4a

	Quite low	Low and low	Unchanged	High height	Quite high
						Persistent effect of inhibiting odor absorption	1	2	3	4	5

From the results shown in Table 5a and FIG. 5, it is understood that, when inulin is contained in any amount of 0.5 to 3.5% by mass, the flavor-blocking effect is excellent in the persistence of the flavor-blocking effect as compared with 2.0% by mass of fructose as a comparison target.

Further, as is clear from the results of table 6a and fig. 5, when fructose is contained in an arbitrary amount of 0.5 to 3.5 mass%, the flavor-blocking effect is inferior in duration to that of inulin-type levan of 2.0 mass% which is the subject of comparison.

It is believed that inulin-type fructans undergo a thermal decomposition process before sweet flavour is produced by the caramelisation reaction, and therefore slowly and over a long period of time. On the other hand, fructose is considered to produce a sweet flavor in a short time by the caramelization reaction. Since sweet flavors suppress the odor blocking sensation, it is considered that the duration of the odor blocking sensation suppressing effect varies depending on the time of generation of such sweet flavors.

From the above results, it was confirmed that the flavor-absorbing inhibition effect of inulin-type levan was more excellent in persistence than that of fructose.

From the above, it is clear that the tobacco material of this example can continuously suppress the odor blocking sensation from the early stage to the late stage of smoking action (the duration of the odor blocking sensation suppressing effect is excellent).
