The present invention relates to tobacco segments containing low flavor raw materials as fillers.

The non-combustion heating type flavor suction article includes a tobacco segment filled with tobacco material, which generates a flavor when heated. Various fillers for tobacco segments have been proposed. For example, Patent Document 1 discloses that a non-combustible heated flavor suction article is prepared by mixing and rolling a sheet of softened tobacco, a shredded tobacco leaf blend, and/or a reconstituted tobacco, with the aim of reducing shreds. Filling is disclosed.

International Publication No. 2020/258389

By the way, in a non-combustion heating type flavor suction article, if the flavor can be easily adjusted, it will be possible to respond to various user preferences. Conventional combustible cigarettes dilute the flavor by introducing air through a filter or perforations in the mouthpiece. However, in non-combustion heated flavor suction products that generate aerosol by heating the tobacco-containing segment to a relatively low temperature, the aerosol re-agglomerates when air is introduced through the filter or the perforations provided on the mouthpiece. There is a problem that sufficient delivery cannot be achieved. Therefore, a new means is needed to adjust the flavor in a non-combustion heated flavor suction article. In view of such circumstances, an object of the present invention is to provide a non-combustion heated flavor suction article that exhibits a diluted flavor.

The inventors have discovered that the above problem can be solved by using low-flavor raw materials. That is, the above-mentioned problem is solved by the present invention described below.

The figure shows a mode in which shredded tobacco material T and shredded low-flavor raw material L are prepared and filled. However, the shreds may be ones obtained by shredding a sheet in which the sheet-shaped tobacco material T and the low-flavor raw material L are laminated.

FIG. 1E shows a mode in which a sheet-like tobacco filler 21 is compressed and rolled in the longitudinal and transverse directions, and then filled into the wrapper 22. The sheet-shaped tobacco filler 21 may be a sheet in which the sheet-shaped tobacco material T and the low-flavor raw material L are laminated, or the sheet-shaped tobacco material T and the low-flavor raw material L may be stacked side by side or near the side surfaces. A sheet obtained by joining may also be used.

(1) Low-flavor raw material In one embodiment, the heating tobacco segment includes, as a filler, a tobacco material and a low-flavor raw material derived from a plant of the tobacco genus that exhibits a lower flavor than the tobacco material. The filling is a filling for tobacco segments. The low flavor raw material preferably contains 100 ppm or less neophytadiene. Neophytadiene is a type of tobacco component that contributes to flavor. Therefore, materials with low neophytadiene content exhibit low flavor. From this viewpoint, the content of neophytadiene is more preferably 50 ppm or less, more preferably 40 ppm or less, still more preferably 30 ppm or less. Although the lower limit of the amount is not limited, it is, for example, 5 ppm or more.

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

GC/MS analysis is performed using, for example, a gas chromatography (GC/FID) device with a flame ionization detector (6890A GC/FID manufactured by Agilent Technologies, etc.). Preferred conditions are as follows.

Journal of Chromatographic Science, Volume 55, Issue 3, March 2017, Pages 373-377

The low-flavor raw material was filled into a non-combustible heated flavor suction article with a tobacco segment and a mouthpiece segment as shown in Figure 2, and when a smoking test was conducted by multiple well-trained panelists, the following indicators were found: The raw material may have an aroma and taste with a score of 2.0 or less.
Score 1: Very low flavor Score 2: Low flavor Score 3: Standard (flavor of the tobacco material)
Score 4: High aromatic taste Score 5: Very high aromatic taste

The low-flavor raw material is preferably selected from the group consisting of medium-bone chopped, softened chopped, stalked chopped, and combinations thereof. A midrib is a cut of the main vein of a tobacco leaf. The relaxation time is the time when the swelling process has been performed. Stoke cutting is a cut product made from tobacco stems.

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

If the low-flavor raw material has a bulkiness within the above range, the bulk density of the filler can be lowered, so that the effect of diluting the flavor becomes more pronounced. From this viewpoint, the swelling property is more preferably 550 cc/100 g or more, and still more preferably 600 cc/100 g or more. The upper limit is not limited, but may be, for example, 1000 cc/100 g or less.

The content of the low-flavor raw material used in this embodiment is preferably 1 to 75% by weight based on the dry weight of the filler. When the content of the low-flavor raw material is within this range, the flavor can be diluted to an appropriate level without interfering with the original flavor. From this viewpoint, the lower limit of the weight is more preferably 5% by weight or more, still more preferably 8% by weight or more. Similarly, the upper limit is more preferably 68% by weight or less, still more preferably 50% by weight or less, 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.

When the low-flavor raw material includes an aerosol-generating base material, the amount of the low-flavor raw material is preferably 5 to 75% by weight based on the dry weight of the filler. In this case, the lower limit of the weight is more preferably 8% by weight or more. Similarly, the upper limit is more preferably 68% by weight or less, still more preferably 50% by weight or less, particularly preferably 40% by weight or less. The amount of the aerosol-generating base material in the low-flavor raw material is not limited, but can be, for example, about 5 to 20% by weight. Details of the aerosol-generating base material will be described later.

When the low-flavor raw material does not contain an aerosol-generating base material, the amount of the low-flavor raw material is preferably 5 to 50% by weight based on the dry weight of the filler. In this case, the lower limit of the weight is more preferably 8% by weight or more. Similarly, the upper limit is more preferably 40% by weight or less.

The shape of the low-flavor raw material is not limited, as long as it is easily mixed with the tobacco material. In one embodiment, the low flavor raw material is a sheet, shred, or strand. Furthermore, in a preferred embodiment, the low-flavor raw material and the tobacco material have the same shape, and in the most preferred embodiment, the low-flavor raw material and the tobacco material are both shredded.

When the low-flavor raw material includes an aerosol-generating base material, the amount of the aerosol-generating base material is preferably 3 to 30% by weight, more preferably 5 to 20% by weight, based on the low-flavor raw material.

(2) Tobacco material Tobacco material is a material derived from plants of the genus Nicotiana. Specific tobacco materials include materials other than the above-mentioned low-flavor raw materials, such as shredded tobacco, fine tobacco powder, tobacco sheets, and strands, which are commonly used in the field. These may be used alone or in combination. Among these, shredded tobacco and shredded tobacco sheets are preferred because they have excellent mixability with low-flavor raw materials, do not improve ventilation resistance, tend to contribute to aroma and taste, and have high uniformity of shape.

As leaf tobacco, those belonging to the Nicotiana genus, such as tabacum and rustica, can be suitably used. Although the varieties are not limited, one or more of these leaf tobaccos can be used in combination. As a mixture, a blend of the above-mentioned varieties can be used as appropriate so as to obtain the desired taste.

(3) Other components The filler may contain other components, examples of which include an aerosol-generating substrate. The aerosol-generating base material is a material that is vaporized by heating and cooled to generate an aerosol, or a material that generates an aerosol by atomization. When the filler contains an aerosol-generating base material, the effect of diluting the flavor without reducing the amount of smoke is achieved. Known aerosol-generating base materials can be used, and examples thereof include glycerin, vegetable glycerin, polyhydric alcohols such as propylene glycol (PG), triethyl citrate (TEC), triacetin, and the like. In one embodiment, the amount of aerosol-generating substrate can be from 5 to 20% by weight, more preferably from 10 to 15% by weight, based on the dry weight of the filler. If the amount of the aerosol-generating base material exceeds the upper limit, stains or the like may occur in the tobacco segments, and if it is less than the lower limit, the smoke sensation may decrease. The aerosol-generating base material can be added to the low-flavor feedstock, such as by impregnation or spraying. The aerosol-generating base material may be contained in the tobacco material, or may be contained in the low-flavor raw material as described above. Furthermore, the filling may contain a flavoring agent commonly used in the field, such as menthol.

(4) Manufacturing method Tobacco segments can be manufactured by any method, for example, by mixing the tobacco material, the low-flavor raw material, and other ingredients if necessary, and rolling the mixture with a wrapper. As the wrapper, those commonly used in the field can be used.

2. Non-combustion heating type flavor suction article In the present invention, the term "flavor suction article" refers to an article for a user to inhale aroma and taste. Among flavor suction articles, those containing tobacco or components derived from tobacco are referred to as "tobacco flavor suction articles." Tobacco flavor suction articles can be divided into ``combustible tobacco flavor suction articles'' (also simply referred to as ``smoking articles''), which generate an aroma and taste through combustion, and ``non-combustible tobacco flavor suction articles'', which generate a smoke flavor without burning. Broadly classified. Furthermore, non-combustible tobacco flavor suction articles include "non-combustion heated tobacco flavor suction articles" that generate a flavor by heating, and "non-combustion, non-heating tobacco flavor suction articles" that generate a smoke flavor without heating. It is broadly divided into The tobacco segment containing the low-flavor raw material of the present invention is suitable for a non-combustion heated tobacco flavor suction article.

FIG. 2 shows one embodiment of a non-combustion heating type tobacco flavor suction article. As shown in the figure, the non-combustion heated tobacco flavor suction article 20 includes a tobacco segment 20A, a cylindrical cooling section 20B having perforations on the circumference, and a filter section 20C. The non-combustion heated tobacco flavor suction article 20 may include other members. The axial length of the non-combustion heated tobacco flavor suction 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. Further, the circumferential length of the non-combustible heated tobacco flavor suction 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 length of the tobacco segment 20A is 20 mm, the length of the cooling section 20B is 20 mm, and the length of the filter section 20C is 7 mm. The lengths of these individual members can be changed as appropriate depending on manufacturing suitability, required quality, etc. Although FIG. 2 shows an embodiment in which the first segment 25 is arranged, only the second segment 26 may be arranged on the downstream side of the cooling section 20B without this arrangement.

1) Tobacco segment 20A
The tobacco filler 21 in the tobacco segment 20A includes the tobacco material and low flavor raw material. The method of filling the tobacco filling 21 into the wrapper 22 is not particularly limited, but for example, the tobacco filling 21 may be wrapped in the wrapper 22, or the tobacco filling 21 may be filled into the cylindrical wrapper 22. When the tobacco and low-flavor raw material have a longitudinal direction, such as a rectangular shape, they may be packed so that the longitudinal direction is in an unspecified direction within the wrapper 22, or in the axial direction of the tobacco segment 20A. They may be filled in alignment or in a direction perpendicular to this. Moreover, the low-flavor raw material described above can also be used as the wrapper 22. By heating the tobacco segment 20A, the tobacco components, aerosol-generating base material, and water contained in the tobacco filler 21 are vaporized and subjected to suction.

2) Cooling section 20B
It is preferable that the cooling unit 20B is formed of a cylindrical member. The cylindrical member may be, for example, a paper tube 23 made of cardboard processed into a cylindrical shape. The cooling portion 20B may also be formed by a thin sheet of material that is wrinkled and then pleated, gathered, or folded to form channels. As such a material, for example, a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil can be used. The total surface area of the cooling section 20B is appropriately adjusted in consideration of cooling efficiency, and can be set to, for example, 300 to 1000 mm ² /mm. The cooling section 20B is preferably provided with perforations 24. Due to the presence of the perforations 24, outside air is introduced into the cooling section 20B during suction. As a result, the vaporized aerosol component generated by heating the tobacco segment 21A comes into contact with the outside air, and as its temperature decreases, it liquefies and forms an aerosol. The diameter (length across) of the perforation 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 around the circumference of the cooling section 20B.

The cooling unit 20B can be shaped like a rod with an axial length of, for example, 7 to 28 mm. For example, the length of the cooling part 20B in the axial direction can be 18 mm. The cooling part 20B has a substantially circular axial cross-sectional shape, and can have a diameter of 5 to 10 mm. For example, the diameter of the cooling section can be approximately 7 mm.

3) Filter section 20C
Although the configuration of the filter section 20C is not particularly limited, it may be configured from a single or multiple filling layers. The outside of the packed layer may be wrapped with one or more wrapping papers. The ventilation resistance of the filter section 20C can be changed as appropriate depending on the amount of filter filler, material, etc. filled in the filter section 20C. For example, when the filter filling is cellulose acetate fibers, the ventilation resistance can be increased by increasing the amount of cellulose acetate fibers filled in the filter section 20C. When the filter filling is cellulose acetate fibers, the packing density of the cellulose acetate fibers can be 0.13-0.18 g/cm ³ . The ventilation resistance is a value measured by a ventilation resistance measuring device (trade name: SODIMAX, manufactured by SODIM).

Although the circumferential length of the filter section 20C is not particularly limited, it is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The length of the filter section 20C in the axial direction (horizontal direction in FIG. 2) can be selected from 4 to 10 mm, and is selected so that the ventilation resistance thereof is 15 to 60 mmH ₂ O/seg. The length of the filter portion 20C in the axial direction is preferably 5 to 9 mm, more preferably 6 to 8 mm. The cross-sectional shape of the filter section 20C is not particularly limited, but may be, for example, circular, elliptical, polygonal, or the like. Further, a breakable capsule containing a fragrance, fragrance beads, or a fragrance may be directly added to the filter portion 20C.

The filter section 20C may include a center hole section as the first segment 25. The center hole portion includes a first filling layer 25a having one or more hollow portions, and an inner plug wrapper (inner wrapper) 25b covering the filling layer. The center hole portion has a function of increasing the strength of the mouthpiece portion. The center hole portion may not have the inner plug wrapper 25b and its shape may be maintained by thermoforming. The filter section 20C may include a second segment 26. The second segment 26 includes a second filling layer 26a and an inner plug wrapper (inner wrapping paper) 26b that covers the second filling layer. The second packed layer 26a has an inner diameter of 5.0 to 1.0 mm, for example, filled with cellulose acetate fibers at high density and hardened by adding a plasticizer containing triacetin in an amount of 6 to 20% by weight based on the weight of cellulose acetate. It can be a rod. Since the second packed layer has a high packing density of fibers, during suction, air and aerosol flow only through the hollow portion, and hardly flow inside the second packed layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the touch feeling from the outside during use is less likely to cause discomfort to the user.

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. Further, 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 glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 28 and wrapping the three members together. These members may be connected at multiple times using multiple lining papers.

The combination of a non-combustion heated tobacco flavor suction article and a heating device for generating an aerosol is also particularly referred to as a non-combustion heated tobacco flavor suction system. An example of this system is shown in FIG. In the figure, the non-combustion heated tobacco flavor suction system includes a non-combustion heated tobacco flavor suction article 20 and a heating device 10 that heats the tobacco segment 20A from the outside.

The heating device 10 includes 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 a heater 12 and a metal tube 13 are arranged at positions corresponding to the tobacco segments 20A to be inserted into the recess 16. The heater 12 may be an electric resistance heater, and electric power is supplied from the battery unit 14 according to instructions from a control unit 15 that controls temperature, and the heater 12 is heated. Heat emitted from heater 12 is transmitted to tobacco segment 20A through metal tube 13 with high thermal conductivity. Although the figure shows a mode in which the heating device 10 heats the tobacco segment 20A from the outside, it may also heat the tobacco segment 20A from the inside. The heating temperature by the heating device 10 is not particularly limited, but is preferably 400°C or lower, 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.

Materials derived from plants of the genus Nicotiana and containing neophytadiene in the amounts shown in Table 1 were prepared. Quantification of neophytadiene was performed as follows with reference to the above-mentioned literature.
1) 0.1 g of the sample was weighed and placed in a 15 ml centrifuge tube with a screw cap.
2) An n-hexane solution (quinoline concentration = 6.45 mmol/l) containing quinoline as an internal standard substance was prepared.
3) 6.0 ml of the n-hexane solution was added to the centrifuge tube, and shaking extraction was performed 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 subjected to GC/MS analysis using a gas chromatography (GC/FID) device equipped with a flame ionization detector (6890A GC/FID manufactured by Agilent Technologies) to quantify neophytadiene. The analysis conditions were as described above.

[Comparative example A1]
A tobacco sheet was manufactured using tobacco leaves according to a standard method. The tobacco sheet was cut into pieces and used as a filler to produce a non-combustion heated tobacco flavor suction article shown in FIG. 2. The product was subjected to a smoking test with 10 well-trained panelists.

[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 materials 4 to 6 and 8 to 10, each of which has a neophytadiene content of 100 ppm or less, shown in Table 1. A shredded mixture was prepared by mixing the base shredded material and the shredded material 4 at a weight ratio of 9:1. Using the shredded mixture as a filler, a non-combustion heated tobacco flavor suction article was manufactured and evaluated in the same manner as in Comparative Example A1. In the same manner, non-combustion heated tobacco flavor suction articles using Materials 5, 6, 8 to 10 were manufactured and evaluated. The results are shown in Table 1.

The evaluation criteria for dilution effect were as follows.
H: High dilution effect.
Y: There is a dilution effect.
N: No dilution effect.

In addition, evaluations were made using scores based on the following criteria.
Score 1: Very low flavor Score 2: Low flavor Score 3: Standard (in this example, the flavor in Comparative Example A1)
Score 4: High flavor and flavor Score 5: Very high flavor and flavor Table 1 also shows the results of evaluating the bulkiness of each material.
