  • flavored and aged tobacco leaves which were aged for about a week did not have an effect of improving the quality of flavoring components due to aging
  • flavored and aged tobacco leaves which were aged for about 4 weeks and flavored and aged tobacco leaves which used tobacco leaves having a total sugar content of about 15 wt% showed degradation of physical properties of tobacco leaves and degradation of yield

  • the sensory evaluation was performed by a panel of twenty-seven evaluators using the smoking articles manufactured according to the examples and comparative examples, based on a scale of 7 points.
  • FIG. 3 is a view illustrating a comparison of results of sensory evaluation of the smoking articles manufactured according to the examples and comparative examples.
  • the tobacco smoke taste intensity, flavor intensity, and satisfaction with the flavor were the same or higher, the off-taste was reduced, and the overall tobacco taste was also enhanced as compared to the comparative examples.
  • Example 1 in which tobacco leaves were flavored with a vanilla concentrate
  • Example 2 in which tobacco leaves were flavored with a chocolate concentrate
  • the flavor intensity, satisfaction with the flavor, refreshingness of aftertaste, and overall tobacco taste were higher as compared to the comparative examples and other examples, and the off-taste reducing effect and irritation reducing effect were also greater as compared to the other examples.
  • smoking articles in which flavored and aged tobacco leaves were mixed had less artificial taste and flavor and also had decreased negative attributes felt during smoking, such as a spicy taste and a coating sensation, as compared to smoking articles in which non-aged tobacco leaves or non-flavored tobacco leaves were mixed.
