Evaluation of Tobacco Mixing Uniformity Based on Chemical Composition
This paper studies the comprehensive evaluation method of tobacco mixing uniformity using information entropy to determine the index weight. Relatively independent chemical compositions which have a major impact on the quality of tobacco, such as reducing sugar, nicotine, chloride and potassium were sampled repetitiously and calculated the average and coefficient of variance. Tobacco mixing uniformity is evaluated by the score according to coefficient of variance. Comprehensive evaluation of five batches of tobacco carried out and the results are consistent with the traditional. This method is easy to get basic data and evaluation results fit the actual. It is a simple and practical evaluation method of mixing uniformity.
