The effects of redrying temperatures on chemical components, aroma components and sensory quality of middle and upper leaves of tobacco C2F, C3F, B1F and B2F in Yunnan and Sichuan provinces were investigated. The experimental results showed that total sugar and reducing sugar content in middle leaves and in B2F and ratios of sugar to alkali in C2F and C3F increased when redrying temperature increased; while total alkaloid，total nitrogen and ratios of nitrogen to alkaloid were less influenced. When redrying temperature was in the range of 80 ℃ to 85 ℃, key volatile aroma components including plastid pigment degradation products, maillard products and cembranoid diterpenes were high, at the same time, sensory qualities of the fresh flavor style tobacco including aroma quality and quantity, irritancy, offensive odor, after taste and aroma note were better. Therefore, redrying temperatures for middle and upper leaves in the range of 80 ℃ to 85 ℃ was more appropriate.
