Method for comprehensively evaluating quality of batch tobacco leaves

The invention discloses a method for comprehensively evaluating quality of batch tobacco leaves. The method comprises the steps of acquiring a preliminary flue-cured tobacco sample in a batch transferring process, measuring data of appearance, chemical and sensory quality evaluation data of the flue-cured tobacco, calculating the score of each quality evaluation index through constructing a conformity function model and dimensionless processing, and finally integrating a final score in flue-cured tobacco quality evaluation and grade number information in batch transferring for obtaining an evaluation result. The flue-cured tobacco quality evaluation indexes comprise the appearance quality index of the flue-cured tobacco, the routine chemical component index, and the sensory quality characteristic index. The appearance quality index of the flue-cured tobacco is the weighting mean value of single-grade different sample quality inspection data of an industrial enterprise in batch transferring. The routine chemical component index is the comprehensive value of single-grade chemical component conformity. The sensory quality characteristic index is the comprehensive score of the single-grade sensory quality characteristic, wherein the comprehensive score is calculated according to the YC / T 530-2015 flue-cured tobacco and tobacco leaf quality stylistic feature sensory evaluation method.
