Tobacco leaves were produced by cutting tobacco leaves (yellow seeds) with a predetermined width. 0.5% by weight of the carob extract prepared in Example 1 (without enhancement treatment) was added to this cigarette. The cigarette with the carob extract was wound into a cigarette having a winding length of 63 mm and a winding circumference of 24.9 mm.

<Example 26: Sensory evaluation of carob extract>
To the same tobacco as in Example 25, 0.5% by weight of the carob extract enhanced in Example 2 was added. The tobacco cut carob extract was wound into a cigarette shape as in Example 25.

  The cigarettes obtained in Examples 25 and 26 were stored in a thermostatic oven at 70 ° C. in a sealed state for 7 hours. In addition, cigarettes before and after storage were smoked and subjected to a sensory test.

<Evaluation>
A sensory test of aroma and flavor (flavor) was performed on cigarettes during smoking (before and after storage: 7 samples each) by 8 trained panelists, and the averages were evaluated as follows.

・ Score 8.0 or more: A evaluation (there is an additive effect and can be used favorably),
・ Score from 7.0 to less than 8.0: B rating (although there are some drawbacks, it can be used),
-Score less than 7.0: C rating (use is not preferred).

These results are shown in Table 4 below.

  As apparent from Table 4, it can be seen that the cigarette of Example 25 to which the carob extract without the enhancement treatment (Example 1) was added had a lower score after storage than before storage (A evaluation → B evaluation).

  On the other hand, it can be seen that the cigarette of Example 26 to which the carob extract with enhanced treatment (Example 2) was added had a high score even before storage, and the difference between before and after storage was small (A evaluation → A evaluation). This is because the carob extract is enhanced to enhance the characteristics of “caramelic” due to the increase in non-volatile pyrazine compared to Example 25 (before storage: rating 8.3 → 9.1). Since the score is higher than that of Example 25 (average score: 7.5 → 8.0), it means that the storage resistance is excellent.

<Example 27: Sensory evaluation of honey>
To the same tobacco as in Example 25, 0.5% by weight of the honey (no enhancement treatment) used in Example 11 was added. The tobacco with honey was wound into a cigarette having a winding length of 63 mm and a winding circumference of 24.9 mm.

<Example 28: Sensory evaluation of honey>
To the same tobacco as in Example 25, 0.5% by weight of the honey enhanced in Example 14 was added. The tobacco with honey was wound into a cigarette shape as in Example 25.

  The cigarettes obtained in Examples 27 and 28 were stored in a thermostatic oven at 70 ° C. in a sealed state for 7 hours. In addition, cigarettes before and after storage were smoked and subjected to a sensory test.

<Evaluation>
A sensory test of aroma and flavor (flavor) was performed on cigarettes during smoking (before and after storage: 7 samples each) by 8 trained panelists, and the averages were evaluated as follows.

・ Score 8.0 or more: A evaluation (there is an additive effect and can be used favorably),
・ Score from 7.0 to less than 8.0: B rating (although there are some drawbacks, it can be used),
-Score less than 7.0: C rating (use is not preferred).

These results are shown in Table 5 below.

  As apparent from Table 5, it can be seen that the cigarette of Example 27 to which the honey without enhancement treatment (Example 11) was added had a lower score after storage than before storage (A evaluation → B evaluation).

  On the other hand, it can be seen that the cigarette of Example 28 to which honey with enhanced treatment (Example 14) was added had a high score even before storage, and the difference between before and after storage was small (A evaluation → A evaluation). In particular, the cigarette of Example 28 has an enhanced “sweet taste” compared to Example 27 (score 8.6 → 9.3).

  In addition, the cigarette of Example 28 to which honey with enhanced treatment was added had little change in “sweet taste” and “flower, honey-like” even after storage (score 9.3 → 9.1, score 8.8 → 8, respectively) .7).

  This means that the sweet smell is enhanced by thermal decomposition of enhanced DDPM in honey and enhanced honey-like aroma from enhanced 5-MHF, which is highly evaluated even after storage (average) Rating by value 8.5 → 8.3: A evaluation → A evaluation).

<Example 29: Sensory evaluation of mate tea extract>
To the same tobacco as in Example 25, 0.5% by weight of the mate tea extract (without enhancement treatment) prepared in Example 22 was added. Tobacco chopped mate tea extract was wound into a cigarette with a winding length of 63 mm and a winding circumference of 24.9 mm.

<Example 30: Sensory evaluation of mate tea extract>
To the same tobacco as in Example 25, 0.5% by weight of the mate tea extract enhanced in Example 24 was added. Tobacco chopped mate tea extract was wound in a cigarette shape as in Example 25.

  The cigarettes obtained in Examples 29 and 30 were stored in a thermostatic oven at 70 ° C. in a sealed state for 7 hours. In addition, cigarettes before and after storage were smoked and subjected to a sensory test.

<Evaluation>
A sensory test of aroma and flavor (flavor) was performed on cigarettes during smoking (before and after storage: 7 samples each) by 8 trained panelists, and the averages were evaluated as follows.

・ Score 8.0 or more: A evaluation (there is an additive effect and can be used favorably),
・ Score from 7.0 to less than 8.0: B rating (although there are some drawbacks, it can be used),
-Score less than 7.0: C rating (use is not preferred).

These results are shown in Table 6 below.

  As apparent from Table 6, it can be seen that the score of the cigarette of Example 29 to which the mate tea extract (Example 22) without enhancement treatment was added decreased both before and after storage (B evaluation → B evaluation).

  On the other hand, it can be seen that the cigarette of Example 30 to which the mate tea extract with enhanced treatment (Example 24) was added had a high score even before storage, and the difference between before and after storage was small (A evaluation → A evaluation).

  In particular, in the cigarette of Example 30 to which the mate tea extract with enhancement treatment was added, “stimulation” and “bitter taste” were suppressed (score 7.8 → 8.3, score 7.2 → 8.3, respectively), and “Tobacco flavor” is reinforced (score 7.6 → 8.0).

  In addition, the cigarette of Example 30 to which the mate tea extract with enhanced treatment was added had little change in “stimulation” and “tobacco flavor (flavor)” even after storage (score 8.0 to 8.0, score 8.6, respectively) → 8.4).

  This is because the enhanced 3-hydroxy-β-damascon and 4-vinyl guaiacol in the mate tea extract suppress the “stimulation” and “bitter taste” and strengthen the “sweet smell” and “tobacco flavor” after storage. (A rating of 8.1 → 8.2: A rating → A rating).
