  • fragrance component-containing particles specifically, crushed leaf tobacco
  • Example of the present invention Hydroxypropyl cellulose (Nippon Soda Co., Ltd .: Cerney SSL, which has a substitution degree of about 3.5 per glucose) 7.4% by weight, ethanol 48.2% by weight, glycerin 22.2% by weight, crushed leaf tobacco (particle size: 70) 10 g of a concentrated slurry liquid (viscosity: 409.5 [mPa ⁇ s]) consisting of -250 ⁇ m) 22.2% by weight was prepared. In order to adjust the viscosity suitable for coating sheet tobacco, 10 g of concentrated slurry liquid was diluted with 10 g of ethanol to prepare a coating slurry liquid.
  • 0.475 g of coating slurry liquid was spray-coated on one side of a sheet tobacco of 5 cm x 5 cm (0.9 g, basis weight: 360 g / m2). Then, the sheet tobacco was blown at room temperature (22 ° C.) to volatilize the ethanol in the coating slurry liquid. In addition, 0.475 g of the coating slurry liquid was spray-coated on the other surface of the sheet tobacco. Then, the sheet tobacco was blown at room temperature (22 ° C.) to volatilize the ethanol in the coating slurry liquid. As a result, a fragrance-supporting sheet tobacco was prepared.
  • Fragrance-supporting sheet Tobacco was cut to obtain a 0.75 mm ⁇ 1.5 cm cut product.
  • a flavor suction article 4A having the same form as the non-combustion heating type flavor suction article 20 shown in FIG. 5 was prepared.
  • the fragrance-supporting tobacco wrapping paper C was cut into a size of 2.0 cm ⁇ 2.5 cm, and the fragrance-supporting tobacco wrapping paper C was attached to the tip of the non-combustion heating type flavor suction article 20 shown in FIG. Polyvinyl alcohol was used for bonding. As a result, the flavor suction article C was prepared. The flavor suction article C was heated by the heating device 10 shown in FIGS. 3 and 4, and sample evaluation was performed.
  • the flavor suction article C and the flavor suction article D are coated with about 10 mg of glycerin per article, and the amount of glycerin applied is almost the same.
  • the tobacco wrapping paper 22 located closer to the heating portion is coated with glycerin
  • the tobacco filler 21 slightly separated from the heating portion is coated with glycerin. Both articles are different in that they are made. Therefore, it was confirmed that when the flavor suction article C was sucked, the amount of glycerin vapor was larger than that of the flavor suction article D.
  • glycerin vapor could be confirmed throughout the puff period.
  • Non-parel 103 (Freund industry, particle size: 500 to 355 ⁇ m) was used as the granule base material. While rolling 40 g of the granule base material in a coating pan heated by applying hot air, 40 g of the coating slurry liquid was dropped onto the granule base material. During the dropping, the ethanol in the coating slurry liquid was vaporized and removed. As a result, a fragrance-supporting granule base material was prepared.
  • the flavor suction article E was prepared by connecting with the main body 30A.
  • the fragrance-supported granule base material could be prepared.
  • a photograph of the prepared fragrance-supporting granule base material is shown in FIG.
  • FIG. 13 shows the appearance of the granule base material, the appearance of the fragrance-supported granule base material, the cut surface of the fragrance-supported granule base material, and the cut surface (enlarged) of the fragrance-supported granule base material in order from the left. Photographs of the cut surface showed that the powder layer containing the pulverized leaf tobacco was fixed to the surface of the granule base material.
  • a laminate of aluminum foil and paper (hereinafter referred to as aluminum molded paper) was used.
  • aluminum molded paper an aluminum laminated paper obtained by bonding aluminum foil to the paper with an adhesive was used.
  • the coating slurry liquid was applied to the paper surface side of 0.672 g of aluminum molded paper with a bar coater (OSG System Products Co., Ltd .: Wireless Bar Coater).
  • the slurry-coated aluminum molded paper was allowed to stand at room temperature of 22 ° C. to volatilize the ethanol in the coated slurry liquid.
  • 1.222 g of fragrance-supported aluminum molded paper was obtained.
  • 250 mg of the perfume-supported aluminum molded paper was cut to a width of about 1 mm, and the obtained cut product was filled in the non-combustion heating type flavor suction article 20 shown in FIG.
  • the flavor suction article F was prepared.
  • the fragrance-supported aluminum molded paper could be prepared.
  • a photograph of the prepared fragrance-supported aluminum molded paper is shown in FIG.
  • FIG. 14 shows the paper surface side and the aluminum surface side of the aluminum molded paper, and the paper surface side (fragrance supporting side) and the aluminum surface side of the fragrance-supported aluminum molded paper in this order from the left.
  • FIG. 15 shows a cut product of fragrance-supported aluminum molded paper. From FIGS. 14 and 15, it was shown that the powder layer containing the pulverized leaf tobacco was fixed to the surface of the aluminum molded paper on the paper surface side.
