Preliminary Division of the Use Groups of Raw Tobacco Leaves Based on Fuzzy Comprehensive Evaluation

In order to divide the raw tobacco leaves more reasonably, 19 kinds of tobacco leaf materials of one among Changbaishan cigarette brands were divided into 3 type modules with the method of fuzzy comprehensive evaluation and evaluated in the sensory quality. 3 type modules included oriented tobacco module the similarity of whose tobacco leaves to the finished cigarette was above 0.8, body type tobacco module whose similarity was 0.60-0.79 and filling type tobacco module whose similarity was below 0.60. The results showed that: the conclusion of fuzzy comprehensive evaluation in the division of the raw tobacco leaves with chemical components was almost the same to that of sensory evaluation, whose self-agreement was 78.95%, and the method of fuzzy comprehensive evaluation in the division of tobacco leaf materials had a certain practical value.
