Description

[Technical Field]

[0001] The present invention relates to tobacco segments that include a low flavor material as a filler. [Background technology]

[0002] Non-combustion heating flavor inhalation articles include tobacco segments filled with tobacco material, which generate a flavor when heated. Various materials have been proposed as the tobacco segment filler. For example, Patent Document 1 discloses that a sheet made by mixing and rolling a softened tobacco, a shredded tobacco leaf blend, and / or a reconstituted tobacco is used as the filler for a non-combustion heating flavor inhalation article, with the aim of reducing the amount of tobacco residue. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2020 / 258389 Summary of the Invention [Problem to be solved by the invention]

[0004] If the flavor and taste of non-combustion heating flavor inhalation articles could be easily adjusted, it would be possible to accommodate a variety of user preferences. In conventional combustion-type cigarettes, the flavor and taste have been diluted by introducing air through perforations on the filter or mouthpiece side. However, in non-combustion heating flavor inhalation articles that generate aerosol by heating tobacco-containing segments to a relatively low temperature, introducing air through perforations on the filter or mouthpiece side causes the aerosol to re-agglomerate, resulting in insufficient delivery. Therefore, a new means is needed to adjust the flavor and taste of non-combustion heating flavor inhalation articles. In view of these circumstances, an object of the present invention is to provide a non-combustion heating flavor inhalation article that exhibits a diluted flavor and taste. [Means for solving the problem]

[0008] The present invention will be described in detail below. In the present invention, "X to Y" includes the extreme values ​​X and Y.

[0009] 1. Tobacco heating segment A tobacco segment is a columnar member that releases flavor and aroma components contained in tobacco material. A tobacco segment for heating is a tobacco segment that releases flavor and aroma components when heated. An overview of a tobacco segment is shown in FIG. 1A. A tobacco segment 20A comprises a tobacco filler 21 and a wrapper 22 that wraps around it. The tobacco filler 21 contains tobacco material T and a light flavor raw material L. In the figure, the tobacco material T and the light flavor raw material L are in the form of strands, but their shapes are not limited thereto and may be, for example, shredded. The strands may also be cut from a sheet in which sheet-shaped tobacco material T and light flavor raw material L are laminated.

[0010] 1B shows an embodiment in which a sheet-like tobacco filler 21 is spirally packed into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating a sheet-like tobacco material T and a low-flavor raw material L, or may be a sheet obtained by joining the sides of the sheet-like tobacco material T and the sheet-like low-flavor raw material L together or at portions near the sides.

[0011] 1C shows an embodiment in which a sheet-like tobacco filler 21 is folded and filled into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating a sheet-like tobacco material T and a low-flavor raw material L, or may be a sheet obtained by joining the sides of the sheet-like tobacco material T and the low-flavor raw material L together or at portions near the sides.

[0012] 1D shows an embodiment in which shredded tobacco filler 21 is filled into a wrapper 22. This figure shows an embodiment in which shredded tobacco material T and shredded low-flavor raw material L are separately prepared and filled. However, the shredded tobacco may be obtained by cutting a sheet in which sheet-shaped tobacco material T and low-flavor raw material L are laminated.

[0013] 1E shows an embodiment in which a sheet-like tobacco filler 21 is compressed in the longitudinal and lateral directions, rolled up, and then packed into a wrapper 22. The sheet-like tobacco filler 21 may be a sheet obtained by laminating sheet-like tobacco material T and low-flavor raw material L, or may be a sheet obtained by joining the sides of the sheet-like tobacco material T and the low-flavor raw material L together or at portions near the sides.

[0014] (1)Low flavor raw materials As one aspect, the tobacco segment for heating includes, as a filling material, a tobacco material and a low-flavor raw material derived from a tobacco plant that exhibits a lower flavor than the tobacco material. The filling material is a filling material for a tobacco segment. The low-flavor raw material preferably contains neophytadiene at 100 ppm or less. Neophytadiene is a kind of tobacco component and contributes to the flavor. Therefore, a material with a low content of neophytadiene exhibits a low flavor. From this perspective, the content of neophytadiene is more preferably 50 ppm or less, more preferably 40 ppm or less, and even more preferably 30 ppm or less. The lower limit of this amount is not limited, but for example, it is 5 ppm or more.

[0015] The neophytadiene content is measured by the following procedure with reference to the literature described later. 1) Weigh 0.1 g of the sample and put it into a 15 ml centrifuge tube with a screw cap. 2) Prepare an n-hexane solution containing quinoline as an internal standard substance (quinoline concentration = 6.45 mmol / l). 3) Add 6.0 ml of the n-hexane solution to the centrifuge tube and perform shaking extraction at 70 °C and a vibration frequency of 250 rpm for 60 minutes. 4) Filter the extract with a fluororesin filter having a pore size of 0.45 μm and collect the filtrate in a vial. Perform GC / MS analysis on the extract under the conditions shown below.

[0016] The GC / MS analysis is performed using, for example, a gas chromatography (GC / FID) apparatus with a flame ionization detector (such as Agilent Technologies 6890A GC / FID). The preferable conditions are as follows. <GC conditions> Column: HP-1MS (manufactured by Agilent Technologies) Inner diameter 0.25 mm × length 30 m, film thickness 0.25 μm Injection volume: 1 μl Injection mode: PTV splitless, injection port temperature: 40 °C (0.1 minute) → 100 °C / min (temperature increase) → 350 °C (5 minutes) → 15 °C / min (temperature decrease) → 40 °C Septum purge flow rate: 3 ml / min Carrier gas: Helium Column flow rate: 1 ml / min (constant flow mode) Oven temperature: 35°C → 20°C / min (temperature increase) → 40°C (2 min) → 3°C / min (temperature increase) → 300°C (23 min) <FID conditions> Detector temperature: 300°C Hydrogen flow rate: 3 ml / min Air flow rate: 400 ml / min Make-up gas (nitrogen): 25 ml / min <Literature> Extraction of Volatile Flavor Compounds From Tobacco Leaf Through a Low-Density Polyethylene Membrane Michinori Yokoi, Mitsuya Shimoda Journal of Chromatographic Science, Volume 55, Issue 3, March 2017, Pages 373-377

[0017] The low-flavor raw material may be a raw material having a flavor score of 2.0 or less according to the following criteria when filled in a non-combustion heating type flavor inhalation article provided with a tobacco segment and a mouthpiece segment as shown in FIG. 2 and subjected to a smoking test by a plurality of well-trained panelists. Score 1: The flavor is very low Score 2: The flavor is low Score 3: Standard (the flavor of the tobacco material) Score 4: The flavor is high Score 5: The flavor is very high

[0018] The low-flavor raw material is preferably selected from the group consisting of midrib cuts, mild cuts, stalk cuts, and combinations thereof. A midrib cut is a cut of the main vein of a tobacco leaf. A mild cut is a cut that has been subjected to puffing treatment. A stalk cut is a cut of the stem of a tobacco.

[0019] The low-flavor raw material preferably has a bulk expansion of 500 cc / 100 g or more. The bulk expansion is the volume per unit weight when a mass of tobacco filler (preferably shredded tobacco) is compressed with a certain force, and is also an index of bulk density. Specifically, the bulk expansion is calculated using the following formula from the height of a tobacco shred cylinder measured after placing a sample in a 95 mm diameter measuring cylinder and applying a load of 11.4 kg for 5 seconds. FP = (A × h5) / W [cm 3 / 100g] FP: bulkiness A: Cross-sectional area of ​​the tobacco cylinder W: Weight of tobacco shreds h5: Height of the tobacco shredded cylinder at the end of loading

[0020] When the low-flavor raw material has a swelling capacity within the above range, the bulk density of the filling can be reduced, resulting in a more pronounced dilution effect of the flavor. From this perspective, the swelling capacity is more preferably 550 cc / 100 g or more, and even more preferably 600 cc / 100 g or more.

[0021] The content of the low-flavor ingredient used in this embodiment is preferably 1 to 75% by weight based on the dry weight of the filling. When the content of the low-flavor ingredient is within this range, the flavor can be diluted to an appropriate level without impairing the original flavor or aroma. From this perspective, the lower limit of the weight is more preferably 5% by weight or more, and even more preferably 8% by weight or more. Similarly, the upper limit is more preferably 68% by weight or less, even more preferably 50% by weight or less, and particularly preferably 40% by weight or less. The dry weight is the weight of the residue when the filling is dried at 100°C for 5 hours in one embodiment.

[0022] When the low-flavor ingredient contains an aerosol-forming base material, the amount of the low-flavor ingredient is preferably 5 to 75 wt % relative to the dry weight of the filling. In this case, the lower limit of the weight is more preferably 8 wt % or more. Similarly, the upper limit is more preferably 68 wt % or less, even more preferably 50 wt % or less, and particularly preferably 40 wt % or less. The amount of the aerosol-forming base material in the low-flavor ingredient is not limited, but can be, for example, about 5 to 20 wt %. Details of the aerosol-forming base material will be described later.

[0023] When the low-flavor ingredient does not contain an aerosol-forming base material, the amount of the low-flavor ingredient is preferably 5 to 50 wt % based on the dry weight of the filling. In this case, the lower limit of the weight is more preferably 8 wt % or more. Similarly, the upper limit is more preferably 40 wt % or less.

[0024] The shape of the low-flavor ingredient is not limited, as long as it is easily mixed with the tobacco material. In one embodiment, the low-flavor ingredient is in the form of a sheet, shreds, or strands. In a preferred embodiment, the low-flavor ingredient and the tobacco material are in the same shape, and in a most preferred embodiment, both the low-flavor ingredient and the tobacco material are in the form of shreds.

[0025] When the low-flavor raw material contains an aerosol-forming base material, the amount of the aerosol-forming base material is preferably 3 to 30% by weight, more preferably 5 to 20% by weight, relative to the low-flavor raw material.

[0026] (2) Tobacco materials Tobacco materials are materials derived from plants of the genus Nicotiana. Specific examples of tobacco materials include materials other than the low-flavor raw materials, such as tobacco shreds, tobacco powder, tobacco sheets, and strands, which are commonly used in the art. These materials are used alone or in combination. Among these, cut tobacco shreds and tobacco sheets are preferred from the viewpoints of excellent mixing with low-flavor raw materials, not increasing air resistance, contributing to the aroma and flavor of tobacco, and having a highly uniform shape.

[0027] As the leaf tobacco, species of the genus Nicotiana, such as Tabacum and Rustica, can be suitably used. There are no limitations on the variety, and one or more of these leaf tobaccos can be mixed and used. The mixture can be a suitable blend of the aforementioned varieties to achieve the desired flavor.

[0028] (3) Other ingredients The filler may contain other components, such as an aerosol-generating substrate. An aerosol-generating substrate is a material that vaporizes when heated and cools to generate an aerosol, or that generates an aerosol by atomization. When the filler contains an aerosol-generating substrate, it can effectively dilute the flavor and aroma without reducing the amount of smoke. Known aerosol-generating substrates can be used, including polyhydric alcohols such as glycerin, vegetable glycerin, and propylene glycol (PG), as well as triethyl citrate (TEC) and triacetin. In one embodiment, the amount of the aerosol-generating substrate can be 5 to 20 wt %, more preferably 10 to 15 wt %, based on the dry weight of the filler. If the amount of the aerosol-generating substrate exceeds the upper limit, stains may occur on the tobacco segments, while if it is below the lower limit, the perceived smoke intensity may be reduced. The aerosol-generating substrate can be added to the low-flavor raw material by impregnation, spraying, or the like. The aerosol-generating substrate may be contained in the tobacco material, or, as described above, in the low-flavor raw material. The filling may also contain flavorings such as menthol that are commonly used in the art.

[0029] (4) Manufacturing method The tobacco segments can be produced by any method, for example, by mixing the tobacco material, the low-flavor ingredient, and optionally other ingredients, and wrapping the mixture in a wrapper. Any wrapper commonly used in the art can be used.

[0030] 2. Non-combustion heating type flavor inhalation product In the present invention, a "flavor inhalation article" refers to an article with which a user inhales a smoking flavor. Among flavor inhalation articles, those containing tobacco or components derived from tobacco are called "tobacco flavor inhalation articles." Tobacco flavor inhalation articles are broadly classified into "combustion-type tobacco flavor inhalation articles" (also simply referred to as "smoking articles") that generate a smoking flavor by combustion, and "non-combustion-type tobacco flavor inhalation articles" that generate a smoking flavor without combustion. Furthermore, non-combustion-type tobacco flavor inhalation articles are broadly classified into "non-combustion-heated tobacco flavor inhalation articles" that generate a smoking flavor by heating, and "non-combustion-non-heated tobacco flavor inhalation articles" that generate a smoking flavor without heating. The tobacco segments containing the low-flavor material of the present invention are suitable for non-combustion-heated tobacco flavor inhalation articles.

[0031] FIG. 2 shows one embodiment of a non-combustion heating tobacco flavor inhalation article. As shown in the figure, the non-combustion heating tobacco flavor inhalation article 20 includes a tobacco segment 20A, a cylindrical cooling section 20B having perforations on its circumference, and a filter section 20C. The non-combustion heating tobacco flavor inhalation article 20 may include other components. The axial length of the non-combustion heating tobacco flavor inhalation article 20 is not limited, but is preferably 40 to 90 mm, more preferably 50 to 75 mm, and even more preferably 50 to 60 mm. The circumferential length of the non-combustion heating tobacco flavor inhalation article 20 is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. For example, the tobacco segment 20A may have a length of 20 mm, the cooling section 20B may have a length of 20 mm, and the filter section 20C may have a length of 7 mm. The lengths of these individual components can be appropriately changed depending on manufacturing suitability, required quality, and the like. Although FIG. 2 shows an embodiment in which the first segment 25 is arranged, it is also possible to arrange only the second segment 26 downstream of the cooling section 20B without the first segment 25 being arranged.

[0032] 1) Tobacco Segment 20A The tobacco filler 21 in the tobacco segment 20A contains the tobacco material and the light-flavor ingredient. The method for filling the tobacco filler 21 into the wrapper 22 is not particularly limited; for example, the tobacco filler 21 may be wrapped in the wrapper 22, or the tobacco filler 21 may be filled into a cylindrical wrapper 22. When the tobacco and the light-flavor ingredient have a longitudinal direction, such as a rectangular shape, they may be filled so that the longitudinal direction is in an unspecified direction within the wrapper 22, or they may be filled so that they are aligned in the axial direction of the tobacco segment 20A or in a direction perpendicular to the axial direction. The light-flavor ingredient may also be used as the wrapper 22. When the tobacco segment 20A is heated, the tobacco components, aerosol-generating substrate, and water contained in the tobacco filler 21 are vaporized and available for inhalation.

[0033] 2) Cooling section 20B The cooling section 20B is preferably constructed of a cylindrical member. The cylindrical member may be, for example, a cardboard tube 23 formed by processing cardboard into a cylindrical shape. The cooling section 20B may also be formed from a sheet of thin material that is wrinkled and then pleated, gathered, or folded to form a channel. Examples of such a material include sheet materials selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil. The total surface area of ​​the cooling section 20B is appropriately adjusted taking into account cooling efficiency, but may be, for example, 300 to 1000 mm 2 / mm. The cooling section 20B is preferably provided with perforations 24. The presence of the perforations 24 allows outside air to be introduced into the cooling section 20B during inhalation. As a result, the vaporized components of the aerosol generated by heating the tobacco segment 21A come into contact with the outside air, their temperature drops, and they liquefy, forming an aerosol. The diameter (distance) of the perforations 24 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 24 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 24 may be provided on the circumference of the cooling section 20B.

[0034] The cooling section 20B may be rod-shaped with an axial length of, for example, 7 to 28 mm. For example, the axial length of the cooling section 20B may be 18 mm. The cooling section 20B may have a substantially circular axial cross section with a diameter of 5 to 10 mm. For example, the diameter of the cooling section may be approximately 7 mm.

[0035] 3) The filter part 20C The configuration of the filter part 20C is not particularly limited, and may be composed of one or more packed layers. The outside of the packed layer may be wrapped with one or more sheets of wrapping paper. The airflow resistance of the filter part 20C can be appropriately changed depending on the amount and material of the filter packing filled in the filter part 20C. For example, when the filter packing is cellulose acetate fiber, the airflow resistance can be increased by increasing the amount of cellulose acetate fiber filled in the filter part 20C. When the filter packing is cellulose acetate fiber, the packing density of the cellulose acetate fiber is 0.13 to 0.18 g / cm. 3 The airflow resistance is a value measured using an airflow resistance measuring device (product name: SODIMAX, manufactured by SODIM).

[0036] The circumferential length of the filter portion 20C 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 portion 20C (horizontal direction in FIG. 2) can be selected from 4 to 10 mm, and is selected so that the airflow resistance is 15 to 60 mmH2O / seg. The axial length of the filter portion 20C is preferably 5 to 9 mm, more preferably 6 to 8 mm. The cross-sectional shape of the filter portion 20C is not particularly limited, but may be, for example, circular, elliptical, polygonal, etc. In addition, a flavor-containing breakable capsule, flavor beads, or flavor may be directly added to the filter portion 20C.

[0037] The filter portion 20C may have a center hole portion as the first segment 25. The center hole portion is composed of a first packed layer 25a having one or more hollow portions and an inner plug wrapper (inner wrapping paper) 25b that covers the packed layer. The center hole portion functions to increase the strength of the mouthpiece portion. The center hole portion may not have an inner plug wrapper 25b and its shape may be maintained by thermoforming. The filter portion 20C may have a second segment 26. The second segment 26 is composed of a second packed layer 26a and an inner plug wrapper (inner wrapping paper) 26b that covers the packed layer. The second packed layer 26a may be, for example, a rod with an inner diameter of 5.0 to 1.0 mm, densely packed with cellulose acetate fibers and hardened with 6 to 20 wt. % of a plasticizer containing triacetin added to the cellulose acetate. Because the second packed layer has a high fiber packing density, air and aerosol flow only through the hollow portions during inhalation, with almost no flow within the second packed layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the feel from the outside during use is less likely to cause discomfort to the user.

[0038] The first filling layer 25a and the second filling layer 26a are connected by an outer plug wrapper (outer wrapping paper) 27. The outer plug wrapper 27 can be, for example, a cylindrical piece of paper. The tobacco segment 20A, the cooling section 20B, and the connected first filling layer 25a and second filling layer 26a are connected by a mouthpiece lining paper 28. These connections can be made, for example, by applying a glue such as a vinyl acetate glue to the inner surface of the mouthpiece lining paper 28 and wrapping the three components. These components may also be connected in multiple layers using multiple lining papers.

[0039] A combination of a non-combustion heated tobacco flavor inhalation article and a heating device for generating an aerosol is also referred to as a non-combustion heated tobacco flavor inhalation system. An example of such a system is shown in Fig. 2. In the figure, the non-combustion heated tobacco flavor inhalation system includes a non-combustion heated tobacco flavor inhalation article 20 and a heating device 10 that heats a tobacco segment 20A from the outside.

[0040] The heating device 10 comprises a body 11, a heater 12, a metal tube 13, a battery unit 14, and a control unit 15. The body 11 has a cylindrical recess 16, and the heater 12 and metal tube 13 are disposed at positions corresponding to the tobacco segment 20A to be inserted therein. The heater 13 may be an electric resistance heater, and is heated by power supplied from the battery unit 14 in response to instructions from the temperature-controlling control unit 15. The heat generated by the heater 12 is transferred to the tobacco segment 20A through the metal tube 13, which has high thermal conductivity. While the figure shows a heating device 10 that heats the tobacco segment 20A from the outside, it may also heat from the inside. The heating temperature of the heating device 10 is not particularly limited, but is preferably 400°C or less, more preferably 150 to 400°C, and even more preferably 200 to 350°C. The heating temperature refers to the temperature of the heater of the heating device 10. [Example]

[0041] [Preparation of flavor ingredients] Materials derived from Nicotiana plants were prepared, containing the amounts of neophytadiene shown in Table 1. Neophytadiene was quantified as follows, with reference to the aforementioned literature. 1) 0.1 g of sample was weighed out and placed in a 15 ml centrifuge tube with a screw cap. 2) An n-hexane solution containing quinoline as an internal standard (quinoline concentration = 6.45 mmol / L) was prepared. 3) 6.0 ml of the n-hexane solution was added to the centrifuge tube, and extraction was carried out by shaking at 70°C and a vibration frequency of 250 rpm for 60 minutes. 4) The extract was filtered through a fluororesin filter with a pore size of 0.45 μm, and the filtrate was collected in a vial. 5) The extract was analyzed by GC / MS using a gas chromatograph with a flame ionization detector (GC / FID) (Agilent Technologies 6890A GC / FID) to quantify neophytadiene. The analytical conditions were as described above.

[0042] [Comparative Example A1] Tobacco sheets were produced using tobacco leaves by a standard method. The tobacco sheets were shredded into shreds, which were then used as a filler to produce the non-combustion heating smoking articles shown in Figure 2. A smoking test was conducted on the products using 10 well-trained panelists.

[0043] [Example A1] The tobacco sheet prepared in Comparative Example A1 was shredded to prepare shreds (also referred to as "base shreds"). Separately, shreds were prepared for each of Materials 4 to 6 and 8 to 10 shown in Table 1, which have a neophytadiene content of 100 ppm or less. A shred mixture was prepared by mixing the base shreds and shreds from Material 4 in a weight ratio of 9:1. Using this shred mixture as a filler, non-combustion heat-promoting smoking articles were manufactured and evaluated in the same manner as in Comparative Example A1. Non-combustion heat-promoting smoking articles were manufactured and evaluated using Materials 5, 6, and 8 to 10 in the same manner. The results are shown in Table 1.

[0044] The evaluation criteria for the dilution effect were as follows: H: High dilution effect. Y: Has a dilution effect. N: No dilution effect.

[0045] In addition, a score was also given based on the following criteria. Score 1: Very poor flavor Score 2: Poor flavor Score 3: Standard (in this example, the aroma and flavor of Comparative Example A1) Score 4: High flavor Score 5: Very good flavor and aroma Furthermore, the results of the evaluation of the swelling properties of each material are also shown in Table 1.

[0046] [Comparative example A2] The evaluation was carried out in the same manner as in Example A1, except that materials 1 to 3 with neophytadiene contents exceeding 100 ppm shown in Table 1 were used. The results are shown in Table 1.

[0047] [Table 1]

[0048] The flavor dilution effect was achieved by using materials with neophytadiene contents of 0 to 100 ppm.Furthermore, the flavor dilution effect was more pronounced when materials with a swelling capacity of 500 cc / 100 g or more were used.

[0049] [Comparative Example B1] Tobacco sheets were produced using tobacco leaves according to a standard method. The tobacco sheets were used as fillers to produce non-combustion heated smoking articles as shown in Figure 2. A smoking test was conducted on the products using 10 well-trained panelists.

[0050] [Example B1] The same tobacco leaves as those used in Comparative Example B1 were mixed with the ground material 5 in a weight ratio of 8:2 to prepare a sheet mixture, which was then used to manufacture a tobacco sheet by a standard method. The tobacco sheet was then shredded to prepare shreds, which were used as a filler and evaluated in the same manner as in Comparative Example B1.

[0051] [Example B2] The tobacco sheet used in Comparative Example B1 was shredded to prepare shreds. Furthermore, the aforementioned material 5 was shredded to prepare shreds. These two types of shreds were mixed in a weight ratio of 8:2 to produce a shred mixture. This mixture was used as a filler and evaluated in the same manner as in Comparative Example B1. The results are shown in the table below. These results clearly demonstrate that, regardless of the mixing method, low-flavor ingredients exhibit a dilution effect, and that the dilution effect is even more pronounced when the low-flavor ingredients are used in the form of shreds.

[0052] [Table 2]

[0053] [Comparative Example C1] Tobacco sheets were produced using tobacco leaves according to a standard method. Shreds were produced from the tobacco sheets, and the shreds were used as a filler to produce the non-combustion heating smoking article shown in Figure 2. A smoking test was conducted on the product by 10 well-trained panelists.

[0054] [Example C1] The same shredded tobacco sheet as used in Comparative Example C1 was prepared, and the aforementioned Material 5 was also shredded to prepare shredded tobacco. These two types of shredded tobacco were mixed in the weight ratios shown in the table below to prepare a shredded tobacco mixture. This shredded tobacco mixture was used as a filler and evaluated in the same manner as in Comparative Example C1.

[0055] [Table 3]

[0056] [Comparative Example D1] Tobacco sheets were produced using tobacco leaves by a standard method. The tobacco sheets were shredded to prepare shredded tobacco. The shredded tobacco was used as a filler to produce the non-combustion heating smoking article shown in Figure 2. A smoking test was conducted on the product by 10 well-trained panelists.

[0057] [Example D1] The same shredded tobacco sheet as used in Comparative Example D1 was prepared. Separately, 10% by weight of an aerosol-generating base material (glycerin) based on the dry weight of Material 5 was added to the aforementioned Material 5. This material was shredded to prepare shredded tobacco. These two types of shredded tobacco were mixed in the weight ratios shown in the table below to prepare a shredded tobacco mixture.
