Abstract:
The sensory quality changes of 14 redried flue-cured tobacco lamina samples during aging of 7 to 51 months were evaluated. The results showed that: (1) the best aging time of middle and upper leaves from Hunan and Heilongjiang was 23 months; that of middle leaves from Guizhou, Shangdong, Yunnan, Henan and Brazil was 34 months; and that of Guizhou, Shangdong, Yunnan, Henan and Zimbabwe upper leaves was 34~39 months. (2) The total smoking score was related to aging time through a binomial function. (3) During aging, the quality of Yunnan redried lamina increased the highest, followed by Guizhou, and Heilongjiang. By aging, redried lamina of Yunnan and Guizhou achieved the high quality. (4) Upper leaves endured longer time storage than middle leaves. Henan leaves and Zimbabwe upper leaves endured longer time storage than other samples, but Yunnan leaves could not endure long time storage. (5) During aging, aroma volume increased smaller and the changes of offensive odor, offensive taste and aroma quality were the major reasons of the increase of overall sensory quality .
