  • the cut pieces of paper and cut pieces of tobacco sheet were mixed at a weight ratio of 80:20, and a non-combustion heating type flavor inhalation article was prepared in the same manner as in Comparative Example 1, and subjected to a smoking test. .
  • the smoking flavor and amount of smoke were evaluated according to the following criteria. 1: Decrease significantly 2: Decrease 3: No change (standard) 4: increase 5: greatly increase
  • the fiber odor was evaluated according to the following criteria. 1: None (standard) 2: very low 3: low 4: moderate 5: strong
  • Example 2 Comparative Example 3
  • a non-combustion heated flavor inhalation article was prepared in the same manner as in Example 1, except that the tobacco sheet and Material 5 were blended in the amounts shown in Table 2, and a smoking test was conducted.
  • Example 3 Tobacco sheets and Material 5 were blended in the amounts shown in Table 3. However, in Material 5, 10% by weight of glycerin was added as an aerosol-generating base material, based on the dry weight. A non-combustion heated flavor inhalation article was prepared and smoke tested in the same manner as in Example 1, except that the blend was used.
  • the sample liquid was then transferred to a 15 ml centrifuge tube using ML-Q water and centrifuged at 8000 rpm for 15 minutes to remove the supernatant. This washing was repeated three times. After washing, 10 ml of a 5% sulfuric acid aqueous solution was added and hydrolysis was carried out at 100° C. for 2.5 hours. After the hydrolysis reaction was completed, the sample was allowed to cool to room temperature. The precipitate was then filtered off and the filtrate was collected in a 250 ml volumetric flask. After thoroughly washing the residue on the filter paper with ML-Q water, the volume was adjusted to 250 ml. This solution was used as a sample for hemicellulose measurement.
  • the tobacco segment of the present invention can moderately dilute the flavor and taste.
