A method for analyzing the change trend of tobacco leaf style characteristics during the alcoholization process of sheet tobacco

Abstract

The invention discloses an analysis method for the tobacco leaf style characteristic variation trend in the lamina aging process. The analysis method sequentially includes the steps that samples are taken and stored; tobacco leaf style characteristic indexes are graded and screened; the zero-value indexes and the no-variation indexes are deleted, the variation indexes are selected as tobacco leaf style characteristic evaluation indexes; evaluation data are processed in a normalization mode; an evaluation index projection objective function is built; optimization solution is carried out on the projection objective function; tobacco leaf style characteristics are comprehensively evaluated; according to the comprehensive evaluation data, longitudinal data resources are built for parameter estimation to obtain influence factors with significant differences, the factors are compared in a linearly independent pairwise mode to finally obtain the tobacco leaf style characteristic variation trend. The tobacco leaf style characteristics are comprehensively evaluated, and the optimal ageing use time of a tobacco leaf raw material can be fast determined; the analysis method has the advantages of being easy to operate, low in cost, high in evaluation speed and high in evaluation precision and accuracy, and evaluation results takes the various characteristics into consideration.

Description

technical field [0001] The invention relates to a method for analyzing the change trend of tobacco leaf style characteristics, in particular to a method for analyzing the change trend of tobacco leaf style characteristics during the alcoholization process of tobacco leaves, and belongs to the technical field of tobacco leaf quality evaluation. Background technique [0002] In recent years, as the tobacco industry has paid more and more attention to storage and maintenance, a large number of studies have been carried out on the appearance, chemical and sensory qualities of tobacco leaves during the aging process of laminar tobacco. Research reports on trends. [0003] At present, although related research on the style characteristics of raw materials and the style characteristics of base tobacco leaves has become a hot topic in the tobacco industry, due to the complexity of the evaluation of style characteristics and the particularity of its indicators, there is no clear and ...

Problems solved by technology

[0003] At present, although related research on the style characteristics of raw materials and the style characteristics of base tobacco leaves has become a hot topic in the tobacco industry, due to the complexity of the evaluation of style characteristics and the particularity of its indicators, there is no clear and scientific objective synthesis of tobacco leaf style characteristics. Evaluation method

At the same time, combined with the alcoholization process of tobacco, the style characteristics of the same test sample during the alcoholization cycle were tracked and evaluated. The evaluation data were independent among different test samples, but the data measured at different time points for the same test sample were often inconsistent. Independence and correlation, which contradict the independence conditions required by traditional statistics, and the intuitive judgment method used in the past to analyze this type of test data has problems such as poor reliability and large errors
