  • the packing density of the tobacco composition in the tobacco filling of the tobacco-containing segment was 0.34 g / cm 3 .
  • Examples 2 to 5 Comparative Examples 1 to 6
  • 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.
  • Table 1 shows the mass ratio of tobacco sheet and leaf tobacco, bulkiness, aerosol generator content, reducing sugar content, nicotine content, neophytadiene content, and CBT of the tobacco compositions prepared in each Example and Comparative Example. Indicates the content. The bulkiness and the content of each component were measured by the above-mentioned method.
  • 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.
  • 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.
  • CBT neophytadiene and sembratriene diol
  • 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.
  • the tobacco content component is supplemented by mixing the leaf tobacco with the tobacco sheet.
  • 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.
  • 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.
  • Example 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.
  • a non-combustion heating type flavor suction device was produced in the same manner as in Example 1.
  • 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.
