Abstract

[Objective] To clarify the quality difference in different parts of flue-cured tobacco leaves and to provide theoretical support for the selection of cutting methods in threshing and redrying procedures. [Methods] After removing 10cm petioles, each single leaf was evenly divided into 9 locations according to the “#” shape. The differences and characteristics of conventional chemical components and coordination indexes in different locations of leaves were analyzed, and on this basis, entropy-weight TOPSIS analysis and cluster analysis were conducted, so as to evaluate the comprehensive quality of different locations of tobacco leaves. Finally, the sensory quality of the samples was evaluated. [Results] (1) There were significant differences in chemical composition and coordination indexes between different locations of tobacco leaf; (2) Tobacco leaf can be divided into three parts: (I, III, IV, VI), (II, V, VII, IX) and VIII. On the whole, the quality of middle and upper edges of the leaf (I, III, IV, VI) was better, especially the middle edges, but the quality of the base was poor, and the base near the stem (VIII) was the worst in the whole leaf; (3) After tobacco leaf cutting, there are differences in sensory quality between different location combinations, the sensory quality of the middle and upper edges (I, III, IV, VI) of the leaf is the best, and the sensory quality of the leaf base near the stem (VIII) is the worst. [Conclusion] In conclusion, there are certain differences and similarities in the quality of tobacco leaf in different locations, the industrial availability and utilization rate of tobacco raw materials can be effectively improved by cutting. Considering the practical situation, it is more suitable to divide tobacco leaf into middle and upper edges and the rest for separate utilization.
