Description

Tobacco composition, tobacco-containing segment, non-combustion heating type flavor suction device, and non-combustion heating type flavor suction system

The present invention relates to a tobacco composition, a tobacco-containing segment, a non-combustion heating type flavor suction device, and a non-combustion heating type flavor suction system.

In a combustion-type flavor suction device (cigarette), a tobacco-containing segment containing a tobacco filling containing leaf tobacco is burned to obtain a flavor. As an alternative to the combustion-type flavor suction device, a non-combustion heating-type flavor suction device has been proposed in which a tobacco-containing segment is heated instead of being burned to obtain a flavor. The heating temperature of the non-combustion heating type flavor suction device is lower than the combustion temperature of the combustion type flavor suction device, for example, about 400 ° C. or less. As described above, since the heating temperature of the non-combustion heating type flavor suction device is low, an aerosol generator such as glycerin is added to the tobacco filling in the non-combustion heating type flavor suction device from the viewpoint of increasing the amount of smoke. Aerosol generators are vaporized by heating to generate aerosols. Since the aerosol is supplied to the user with a tobacco component, the user can obtain a sufficient flavor.

In the tobacco-containing segment of non-combustion heated flavor suction equipment, the tobacco filler is filled with a tobacco sheet instead of leaf tobacco as a tobacco filler so that the tobacco filler can contain a sufficient amount of aerosol generator. Is usually used (for example, Patent Document 1). The tobacco sheet is obtained by molding a composition containing tobacco into a sheet shape, and contains fibers such as pulp as a filler for molding. Since the fibers can absorb aerosol generators, the tobacco sheet can retain more aerosol generators than leaf tobacco.

On the other hand, Patent Documents 2 to 6 disclose a tobacco composition containing a leaf tobacco and a tobacco sheet, mainly for a combustion-type flavor suction device.

Japanese Patent Publication No. 2014-515274 Special Table 2019-503695 Gazette Special Table 2013-502232 Japanese Unexamined Patent Publication No. 7-184624 Special Table 2018-516705 Publication No. International Publication No. 2011/013478

As mentioned above, the tobacco sheet can contain a large amount of aerosol generator, and the amount of smoke can be secured when using the non-combustion heating type flavor suction device. However, since the tobacco sheet contains fibers such as pulp, a fiber odor may be felt at the time of use. In addition, the tobacco sheet contains materials other than tobacco such as fiber, and since the tobacco sheet loses a part of the tobacco component at the time of its manufacture, the flavor is felt weaker at the time of use and the flavor persistence is lower than that of leaf tobacco. .. Further, the tobacco sheet has a higher production cost than the leaf tobacco due to the partial loss of the tobacco component at the time of production. On the other hand, leaf tobacco has a strong flavor at the time of use, has no fiber odor, and is low in cost, but since it can contain only a small amount of aerosol generator, it is not possible to secure a sufficient amount of smoke.

INDUSTRIAL APPLICABILITY The present invention is a low-cost tobacco composition capable of reducing fiber odor, improving the degree and sustainability of flavor while ensuring a sufficient amount of smoke, and a tobacco-containing segment containing the tobacco composition.

[Tobacco composition]
The tobacco composition according to the present embodiment includes a tobacco sheet and leaf tobacco. Here, in the present embodiment, the mass ratio of the tobacco sheet to the leaf tobacco is tobacco sheet: leaf tobacco = 40 to 80:20 to 60. In addition, the tobacco composition according to this embodiment contains an aerosol generator.

The present inventors have blended a tobacco sheet and a leaf tobacco in a tobacco composition containing an aerosol generator so that the mass ratio of the two is tobacco sheet: leaf tobacco = 40 to 80: 20 to 60. It has been found that the fiber odor can be reduced and the degree and sustainability of the flavor can be improved while ensuring a sufficient amount of smoke. When the mass ratio of the tobacco sheet is 40% by mass or more (the mass ratio of the leaf tobacco is 60% by mass or less), the tobacco composition can contain a sufficient amount of the aerosol generator, and a sufficient amount of smoke is produced at the time of use. Can be secured. In addition, by ensuring a sufficient amount of smoke, the tobacco component is sufficiently supplied to the user by the aerosol, so that the degree and sustainability of the flavor are improved. On the other hand, when the mass ratio of the tobacco sheet is 80% by mass or less (the mass ratio of leaf tobacco is 20% by mass or more), the fiber odor derived from fibers such as pulp contained in the tobacco sheet can be reduced. In addition, since the mass ratio of leaf tobacco increases, the content of tobacco components increases, and the degree and sustainability of flavor are improved. Further, in the present embodiment, since the leaf tobacco is blended with the tobacco sheet, the loss of the tobacco component during production is small as compared with the tobacco composition containing only the tobacco sheet, and the production cost can be reduced. The tobacco composition according to the present embodiment is particularly useful as a tobacco composition for a non-combustion heating type flavor suction device.

In the present embodiment, the mass ratio of the tobacco sheet to the leaf tobacco is tobacco sheet: leaf tobacco = 40 to 80: 20 to 60, and (40 or more and less than 70) :( more than 30 and 60 or less). It is preferably 45 to 69: 31 to 55, more preferably 50 to 69: 31 to 50, and particularly preferably 55 to 68: 32 to 45. Since the tobacco sheet and the leaf tobacco have different appearances, it is possible to separate the two and measure the mass in the tobacco composition containing the tobacco sheet and the leaf tobacco. When a component such as an aerosol generator is added to the leaf tobacco, the mass of the leaf tobacco is the mass including the component. The same applies to tobacco sheets. In addition, the tobacco composition according to the present embodiment can be composed of a tobacco sheet and leaf tobacco.

(Bulbulability)
The swelling property of the tobacco composition according to the present embodiment is preferably 300 to 580 cm ^3/100 g. Since the tobacco sheet has a lower bulkiness than the leaf tobacco, the tobacco composition containing only the tobacco sheet needs to be filled with a larger amount of the tobacco composition in order to obtain a predetermined winding hardness in the tobacco-containing segment. However, since the tobacco composition according to the present embodiment is blended with highly swelling leaf tobacco, it has a higher swelling property than the tobacco composition containing only a tobacco sheet, and the tobacco composition is filled during the production of the tobacco-containing segment. The amount can be reduced. Therefore, the manufacturing cost of the tobacco-containing segment can be reduced. When the swellability of the tobacco composition is 300 cm / ^3/100 g or more, the filling amount of the tobacco composition at the time of producing the tobacco-containing segment can be sufficiently reduced, and the production cost can be further reduced. The swelling property of the tobacco composition is more preferably 300 to 500 cm ^3/100 g, further preferably 300 to 400 cm ^3/100 g, and particularly preferably 330 to 380 cm ^3/100 g.

The swelling property of the tobacco composition is a value measured by the following method. For the measurement of bulging property, DD-60A manufactured by Borgwaldt of Germany can be used. The swellability is a numerical value calculated from the height of the cylinder of the sample obtained after applying a load of 11.4 kg in a measuring cylinder having a diameter of 95 mm in which the sample is placed for 5 seconds. That is, the swelling property represents the volume per unit weight when a mass of a sample is compressed with a constant force.
FP = (A × h5) / W [cm ³ / 100g]
FP: Bulkiness A: Cross-sectional area of the sample cylinder W: Weight of the sample h5: Height of the sample cylinder at the end of loading

(Composition of leaf tobacco)
<Definition>
In the present specification, "leaf tobacco" means harvested tobacco leaves, harvested tobacco leaves that have been deboned and separated into lamina, middle bones, etc., and have undergone aging (including curing). Includes aged leaf tobacco, aged leaf tobacco, etc., which are chopped to a predetermined size.

<Tobacco varieties>
Various varieties of tobacco can be used. For example, yellow varieties, Burley varieties, Orient varieties, native varieties, other Nicotiana-Tabacam varieties, and Nicotiana rustica varieties can be mentioned. These varieties can be used alone, or they can be blended in the process from harvesting leaf tobacco to chopping aged leaf tobacco in order to obtain the desired flavor. Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Academic Studies Center, 2009.3.31".

<Blend of tobacco varieties>
As mentioned above, the blending of tobacco varieties can be carried out in the process from harvesting leaf tobacco to chopping aged leaf tobacco. Generally, "blend" means a mixture of tobacco belonging to the same variety or different varieties, but in the present specification, the combination of different aged leaf tobacco and different tobacco chops is also referred to as "blend". be. Also, blending tobacco of the same variety but with different grades may be particularly referred to as "cross-blending".

In each tobacco variety, leaf tobacco is graded according to characteristics such as origin, arrangement within the plant, color, surface condition, size, and shape. Further, it is considered that leaf tobacco contains more than 300 chemical components, and the chemical properties of tobacco of different varieties are different. Moreover, even if the tobacco of the same variety is different in grade, its chemical properties may be different. Therefore, in order to obtain a tobacco raw material having desired characteristics and desired chemical properties, the above-mentioned blending or cross-blending is performed.

<Treatment of leaf tobacco>
Examples of the treatment that the harvested leaf tobacco receives in the initial stage include curing, treatment in a raw material factory, and aging.

<Curing>
Leaf tobacco is generally subjected to a treatment called curing in the early stages after harvesting. Curing is one of the processes for aging leaf tobacco, and usually includes steps such as drying and humidity control, and also includes activation of various enzymes contained in leaf tobacco. The cured leaf tobacco is packed in a case, stored in a warehouse for a certain period of time, and then transported to a raw material factory. In order to obtain leaf tobacco containing a small amount of benzo [a] pyrene and low-molecular-weight carboxylic acid and a large amount of a specific flavor component, instead of the above-mentioned curing, the harvested leaf tobacco was published in International Publication No. 2018 / The process described in No. 139068 may be performed.

<Processing and aging at raw material factories>
After being unpacked, the cured leaf tobacco transported to the raw material factory is usually subjected to treatments such as humidity control, deboning, and separation to become lamina and middle bone. After that, the re-dried lamina, middle bone, etc. are packed in a case and stored for a long time in a warehouse. The process of long-term storage in this warehouse is sometimes referred to as aging. The aging period varies depending on the varieties of tobacco used, the desired flavor of the tobacco product, and the temperature during aging, but is generally 1 year or more and 2 years or less. A leaf tobacco that has undergone a curing or a treatment alternative to the curing described above, which is one aspect of aging, and has undergone further aging is referred to as "aged leaf tobacco".

It should be noted that the process of treating leaf tobacco into lamina, middle bone, etc., then packing it in a case and aging it may be referred to as post-bone aging. On the other hand, leaf tobacco transported to a raw material factory may be packed in a case and aged without being deboned or separated, and then deboned and separated after aging, which is also called post-aging deboning. ..

<Flavor>
Flavoring may be added to the leaf tobacco. The type of flavoring agent is not particularly limited, and examples thereof include flavoring agents and flavoring agents from the viewpoint of imparting a good flavor. In addition, it may optionally include colorants, wetting agents and preservatives. The flavoring agent and any material may be liquid or solid regardless of their properties. Further, it may be a single component or a combination of a plurality of components.

Suitable flavors of the flavor include tobacco extract and tobacco components, sugar and sugar flavors, licorice, cocorice, chocolate, fruit juice and fruit, spices, liquor, herbs, vanilla, and flower flavors. The fragrances selected from the above can be used alone or in combination.

The lengths of these individual segments can be appropriately changed according to manufacturing aptitude, 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 function as a non-combustion heating type flavor suction device.

(Tobacco-containing segment)
The tobacco-containing segment 2 is a tobacco-containing segment according to the present embodiment. As shown in FIG. 1, when the tobacco-containing segment 2 is heated, the tobacco component (flavor component), aerosol generator and water contained in the tobacco filling are vaporized, and these are vaporized into the mouthpiece segment 6 by suction. Transition.

(Cooling segment)
As shown in FIG. 1, the cooling segment 3 may be composed of 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 total surface area of the cooling segment can be 300 mm ² / mm or more and 1000 mm ² / mm or less. This surface area is the surface area per length (mm) in the cooling segment ventilation direction. The total surface area of the cooling segment is preferably 400 mm ² / mm or more, more preferably 450 mm ² / mm or more, while preferably 600 mm ² / mm or less, preferably 550 mm ² / mm or less. Is more preferable.

It is desirable that the cooling segment has a large total surface area with a large internal structure. Thus, in a preferred embodiment, the cooling segment may be wrinkled to form a channel and then formed by a sheet of pleated, gathered, and folded thin material. Folding or folds within a given volume of the element increases the total surface area of the cooling segment.

In some embodiments, the thickness of the constituent material of the cooling segment can be 5 μm or more and 500 μm or less, for example, 10 μm or more and 250 μm or less.

The aerosol cooling element can be formed from a material having a specific surface area of 10 mm ² / mg or more and 100 mm ² / mg or less. In one embodiment, the specific surface area of the constituent material can be about 35 mm ² / mg. The specific surface area can be determined in consideration of materials having a known width and thickness. For example, the material can be polylactic acid with an average thickness of 50 μm and a variation of ± 2 μm. If the material also has a known width, for example between 200 mm and above, 250 mm and below, the specific surface area and density can be calculated.

The tubular member 7 and the mouthpiece lining paper 12, which will be described later, are provided with a perforation 8 penetrating both of them. The presence of the perforations 8 introduces outside air into the cooling segment 3 during suction. As a result, the aerosol vaporization component generated by heating the tobacco-containing segment 2 comes into contact with the outside air, and the temperature drops, so that the aerosol is liquefied to form an aerosol. The diameter (crossing length) of the perforation 8 is not particularly limited, but may be, for example, 0.5 mm or more and 1.5 mm or less. The number of perforations 8 is not particularly limited, and may be one or two or more. For example, a plurality of holes 8 may be provided on the periphery of the cooling segment 3.

The amount of outside air introduced from the drilling 8 is preferably 85% by volume or less, more preferably 80% by volume or less, based on the total volume of the gas sucked by the user. When the ratio of the amount of outside air is 85% by volume or less, the reduction of flavor due to dilution by the outside air can be sufficiently suppressed. In other words, this is also called the 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 resistance that the cooling segment gives to the air passing through the tobacco-containing segment is preferably small. Preferably, the cooling segment has substantially no effect on the suction resistance of the non-combustion heated flavor suction device. The resistance to suction (RTD) is the pressure required to push air through the entire length of the object under a flow rate test of 17.5 ml / sec at 22 ° C. and 101 kPa (760 tolls). RTD is generally expressed in _mmH2O units and is measured according to ISO 6565: 2011. Therefore, it is preferable that the amount of pressure drop from the upstream end of the cooling segment to the downstream end of the cooling segment is small. To achieve this, it is preferred that the vertical porosity is greater than 50% and the airflow path through the cooling segment is relatively unconstrained. The longitudinal porosity of the cooling segment can be determined by the ratio of the cross-sectional area of the material forming the cooling segment to the internal cross-sectional area of the cooling segment.

In some embodiments, the resulting aerosol may drop by 10 ° C or more as it is sucked into the user through the cooling segment. In another aspect, the temperature may drop by 15 ° C. or higher, and in yet another aspect, the temperature may drop by 20 ° C. or higher.

The cooling segment may be composed of a sheet material selected from the group comprising metal foil, polymer sheets, and substantially non-perforated paper or thick paper. In one embodiment, the cooling segment can include a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil. The constituent material of the cooling segment may be made from a biodegradable material, such as non-perforated paper, a biodegradable polymer such as polylactic acid, or a starch-based copolymer.

It is preferable that the air flow passing through the cooling segment does not substantially deviate between adjacent segments. In other words, the airflow through the cooling segment is preferably along the longitudinal segment with virtually no radial deviation. In some embodiments, the cooling segment is formed from a material with low porosity or substantially no pores, except for longitudinal extending channels. Materials used to define or form longitudinal extending channels, such as wrinkled or gathered sheets, have low porosity or virtually no pores.

As mentioned above, the cooling segment may include a sheet of suitable constituent material wrinkled, pleated, gathered or folded. The cross-sectional profile of such an element may indicate a randomly oriented channel. The cooling segment can be formed by other means. For example, the cooling segment can be formed from a bundle of longitudinally extending tubes. Cooling segments can be formed by extrusion, molding, laminating, injection, or shredding of suitable materials.

The cooling segment can be formed, for example, by wrapping, gathering, or folding a sheet material with rolling paper. In some embodiments, the cooling segment can include a sheet of wrinkled material gathered in a rod shape and tied with a wrapper, for example, a roll of filter paper.

The cooling segment can be formed into a rod shape having an axial length of, for example, 7 mm or more and 28 mm or less. For example, the axial length of the cooling segment can be 18 mm.

In some embodiments, the cooling segment is substantially circular in its axial cross-sectional shape and can have a diameter of 5 mm or more and 10 mm or less. For example, the diameter of the cooling segment can be about 7 mm.

(Center hall segment)
The center hole segment is composed of a packed bed having one or more hollow portions and an inner plug wrapper (inner rolling paper) covering the packed bed. For example, as shown in FIG. 1, the center hole segment 4 is composed of a second packed layer 9 having a hollow portion and a second inner plug wrapper 10 covering the second packed layer 9. The center hole segment 4 has a function of increasing the strength of the mouthpiece segment 6. The second packed bed 9 is hardened with an inner diameter of φ5.0 mm, for example, in which cellulose acetate fibers are packed at high density and a plasticizer containing triacetin is added in an amount of 6% by mass or more and 20% by mass or less with respect to the mass of cellulose acetate. As described above, the rod can be a rod having a diameter of 1.0 mm or less. Since the packed bed 9 of the second packed bed has a high packing density of fibers, air and aerosol flow only in the hollow portion at the time of suction, and hardly flow in the second packed bed 9. Since the second packed bed 9 inside the center hole segment 4 is a fiber packed bed, the feeling of touch from the outside during use is less likely to cause discomfort to the user. The center hole segment 4 may not have the second inner plug wrapper 10 and its shape may be maintained by thermoforming.

(Filter segment)
The structure of the filter segment is not particularly limited, but may be composed of a single or a plurality of packed layers. The outside of the packed bed may be wrapped with one or more sheets of rolling paper. The aeration resistance per segment of the filter segment can be appropriately changed depending on the amount of the filler filled in the filter segment, the material and the like. For example, if the filler is cellulose acetate fibers, increasing the amount of cellulose acetate fibers filled in the filter segment can increase aeration resistance. When the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber can be 0.13 to 0.18 g / cm ³ . The ventilation resistance is a value measured by a ventilation resistance measuring device (trade name: SODIMAX, manufactured by SODIM).

The peripheral length of the filter segment is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The axial length of the filter segment can be selected from 4 to 10 mm, and the ventilation resistance thereof is selected to be 15 to 60 mmH ₂ O / seg. The axial length of the filter segment is preferably 5 to 9 mm, more preferably 6 to 8 mm. The shape of the cross section of the filter segment is not particularly limited, but may be, for example, a circle, an ellipse, a polygon, or the like. In addition, destructive capsules containing fragrances, fragrance beads, and fragrances may be directly added to the filter segment.

As shown in FIG. 1, the center hole segment 4 and the filter segment 5 can be connected by an outer plug wrapper (outer roll paper) 11. The outer plug wrapper 11 can be, for example, cylindrical paper. Further, the tobacco-containing segment 2, the cooling segment 3, and the connected center hole segment 4 and filter segment 5 can be connected by the mouthpiece lining paper 12. These connections can be made by, for example, applying glue such as vinyl acetate glue to the inner side surface of the mouthpiece lining paper 12, inserting the three segments, and winding them. In addition, these segments may be connected in a plurality of times by a plurality of lining papers.

The packing density of the tobacco composition in the tobacco filling of the tobacco-containing segment was 0.34 g / cm ³ .

(5) Manufacture of non-combustion heating type flavor suction device Using the tobacco-containing segment, the non-combustion heating type flavor suction device shown in FIG. 1 described above was manufactured.

[Examples 2 to 5, Comparative Examples 1 to 6]
In the preparation of the tobacco composition, the tobacco composition was prepared in the same manner as in Example 1 except that the mass ratios of the tobacco sheet and the leaf tobacco were changed as shown in Table 1. Further, using the tobacco composition, a tobacco-containing segment and a non-combustion heating type flavor suction device were produced in the same manner as in Example 1.

The evaluation was performed as a comprehensive evaluation through a total of 15 puffs for the four items of "degree of flavor", "persistence of flavor", "fiber odor", and "smoke volume and persistence". For each item, 1 (weak flavor, low flavor persistence, high fiber odor, low smoke volume and low sustainability) to 5 (strong flavor, high flavor persistence, low fiber odor, The amount of smoke is large and the sustainability is high). In each item, if the score is 3 or more, it is good, and if the score is 2 or less, it is judged to be bad. The results are shown in Table 2. Table 2 shows the average score of 10 panelists. In addition, the 10 panelists were well trained using several different concentrations of samples, including "degree of flavor", "persistence of flavor", "fiber odor", and "smoke volume and persistence". It has been confirmed that the scores of "gender" and the thresholds of evaluation are equal and unified among the panelists.

As shown in Table 2, in Examples 1 to 5, all the evaluation items had a score of 3 or more, whereas in Comparative Examples 1 to 6, there were evaluation items having a score of 1 or 2. Therefore, the non-combustion heating type flavor suction device using the tobacco compositions of Examples 1 to 5 according to the present embodiment is compared with the non-combustion heating type flavor suction device using the tobacco compositions of Comparative Examples 1 to 5. It was found that the degree and persistence of flavor, fiber odor, and smoke volume and persistence were all good.

[Reference example]
Principal component analysis was performed on some of the above-mentioned Examples and Comparative Examples with "neophitadiene", "sembratriendiol (CBT)", and "reducing sugar" as variables. The results are shown in Table 3.

As shown in the results of principal component analysis in Table 3, the factor loading of the first principal component was 62.67% of the total, and the factor loading of the second principal component was 91.51% of the total, which was about 9 of the total. It means that you can explain the percentage. According to the principal component load, the first principal component has a high relationship with neophytadiene and sembratriene diol (CBT), and the second principal component has a high relationship with reducing sugars. A scatter plot of the principal component scores is shown in FIG. According to the scatter plot of the principal component scores shown in FIG. 5, leaf tobacco is plotted in the first, second and fourth quadrants, the tobacco sheet is plotted in the third quadrant, and the tobacco composition containing the tobacco sheet and leaf tobacco is plotted. There is. That is, it can be seen that the tobacco content component is supplemented by mixing the leaf tobacco with the tobacco sheet. In this embodiment, the first quadrant is approached by mixing the tobacco sheet with the leaf tobacco, but it is also possible to approach the second and fourth quadrants by changing the mixing ratio of the leaf tobacco. However, as described above, the tobacco sheet can more retain hydrophilic materials such as reducing sugars and components such as glycerin and propylene glycol that are difficult to retain in leaf tobacco. Therefore, by mixing the leaf tobacco and the tobacco sheet at a certain ratio, it is possible to supply the aerosol with sufficient flavor to the user at the time of use.

[Examples 6 to 10]
Tobacco sheets and leaf tobacco were produced by the same method as in Example 1. The tobacco sheet was cut into widths of 0.5 mm, 1.0 mm, and 1.5 mm, respectively. In addition, the leaf tobacco was cut to a width of 0.8 mm. The tobacco composition of each example was prepared by mixing the tobacco sheet having the step size shown in Table 4 and the leaf tobacco so as to have a tobacco sheet: leaf tobacco = 60:40 (mass ratio). Using the tobacco composition, a non-combustion heating type flavor suction device was produced in the same manner as in Example 1. For the non-combustion heating type flavor suction device of each example, the degree of flavor was evaluated in the same manner as in Example 1. The puffing was performed 15 times, and the degree of flavor in each term was evaluated by dividing into 3 terms of 1st to 5th, 6th to 10th, and 11th to 15th. The results are shown in Table 4.

As shown in Table 4, by mixing tobacco sheets with different step widths, it is possible to change the timing of the puff to feel the degree of flavor due to the difference in thermal conductivity. By changing the step size and the combination thereof according to the heating temperature of the non-combustion heating type flavor suction device and the features of the product, the flavor can be further changed. Further, as compared with Examples 6 to 8 and Examples 9 and 10, when the step size of the tobacco sheet is 1.0 mm or less, the delay in the expression of the original flavor of the tobacco sheet can be sufficiently suppressed.
