    Abstract:

    To distinguish the similarities and differences of flue-cured tobacco aroma-note between Yunnan and Fujian, the student-t test, correlation analysis and regression method were adopted to study 157 flue-cured tobacco samples collected from Yunnan and Fujian. The results indicate that fresh-sweetness, straw, and burnt are the top three aroma-notes in Yunnan and Fujian flue-cured tobacco. There is a negative correlation between fresh-sweetness and green in Yunnan and Fujian flue-cured tobacco. However, the aroma-note difference between them is also significant. The fresh-sweetness (green) in Yunnan flue-cured tobacco is stronger (weaker) than Fujian flue-cured tobacco. The differences of corresponding routine chemical components are the content of kalium and chlorine. The content of kalium (chlorine) in Yunnan flue-cured tobacco is significantly lower (higher) than Fujian flue-cured tobacco. The fresh-sweetness and green in Yunnan flue-cured tobacco are closely related to reduced sugar, kalium and the ration of kalium to chlorine, but such relationship is not obvious in Fujian flue-cured tobacco. The green in all aroma-notes could be used as a key index to distinguish the Yunnan flue-cured tobacco and the Fujian flue-cured tobacco.
