Referring to Table 1, in all of Examples 1 to 5, the majority of flavor components increased compared to the unflavored aging (Comparative Example 1), and some flavor components decreased, and the degree of increase or decrease for each flavor component was different for each Example. Could know. Accordingly, it was confirmed that there was a clear difference in the flavor component modification of leaf tobacco depending on whether or not flavoring treatment was performed, the type of flavoring agent during flavoring treatment, and/or aging treatment.

In particular, when cross-referencing the results of Examples 1 to 2 and Comparative Examples 2 to 3, '3,6-Dimethyl-4H-furo[3,2-c] pyran-4-one', '3-Furaldehyde' , '5-Methylfurfural', 'Furfuryl alcohol', etc., most of the flavor components in leaf tobacco did not increase simply by flavoring treatment, but were further increased by the aging process after flavoring treatment.

In addition, in all of the flavored-aged leaf cigarettes of each of Examples, '5-Methylfurfural', '4-Oxoisophorone', and 'Piperonal', such as '5-Methylfurfural', 'Piperonal', etc., were increased in positive flavor components, and in the flavored-aged leaf tobacco of Example 1, ' 2(3H)-Furanone dihydro-5-propyl-', 'gamma-Nonalactone', '3,6-Dimethyl-4H-furo[3,2-c]pyran-4-one', 'Furfryl alcohol', etc. Glycolysis products with roasted flavor properties were particularly increased, and in the flavored-aged leaf tobacco of Example 2, semi-volatile compounds with sweet flavor properties such as 'p-Anisaldehyde' and 'Anisyl acetate' were particularly increased.

On the other hand, although not shown in the table as a separate example or comparative example, the flavor component modification effect according to the aging did not appear in the flavored-aged leaf tobacco aged for about 1 week, and the flavored-aged leaf tobacco aged for about 4 weeks and the total sugar content were about Flavor-aged leaf tobacco using leaf tobacco of 15 wt% showed deterioration in physical properties and yield of leaf tobacco, and flavored-aged leaf tobacco using leaf tobacco having a total sugar content of about 40 wt% was detected in the amount of nicotine less than the reference value, and Comparative Examples.

Referring to Table 2, it was confirmed that most of the flavor components increased after the flavoring aging treatment were slightly decreased after the subsequent process (wet point, moisturizing, slicing, drying, etc.), but the decrease in the amount of ingredients was not large, and further, Furanone, dihydro-5-propyl-', 'gamma-Nonalactone', 'Piperonal', 'Ionene', '2,3'-Dipyridyl', 'Anise alcohol', 'p-Anisaldehyde', 'Megastigmatrienone' and 'p In the case of some glycolysis products such as '-Methylacetophenone' and tobacco-specific flavor components, it can be seen that the amount of components increased after the subsequent process.

실험예 2: 가향 및 숙성유무에 따른 관능평가Experimental Example 2: Sensory evaluation according to flavoring and aging

The sensory evaluation was performed on the taste intensity, aroma intensity, flavor satisfaction, irritation, off-taste, clean aftertaste, and overall tobacco taste of each smoking article in Examples and Comparative Examples. The sensory characteristic evaluation was conducted for 27 evaluation panel members using each of the smoking articles manufactured according to the Examples, and a total score of 7 was used as the standard.

Referring to FIG. 3 , it was confirmed that most of the Examples exhibited equal or higher taste intensity, flavor intensity, and flavor satisfaction compared to Comparative Examples, reduced taste, and increased overall tobacco taste.

In particular, in the case of Example 1 flavored with vanilla concentrate and Example 2 flavored with chocolate concentrate, higher flavor strength, flavor satisfaction, clean aftertaste, and overall tobacco taste characteristics were shown compared to Comparative Examples and other Examples, It was confirmed that the effect of reducing taste and irritation was also superior to that of the other examples.

Furthermore, through the smoking evaluation results in addition to the items of the evaluation panel members, smoking articles containing flavored aged leaf tobacco have less artificial taste and flavor than smoking products containing unaged leaf tobacco or unscented leaf tobacco, and It was also found that the perceived negative attributes decreased.
