Embodiment Construction

[0015] The present invention will be further described below through specific examples.

[0016] The method of using characteristic index to characterize tobacco leaf style features provided by the present invention selects and selects characteristic chemical indexes of tobacco leaves, calculates the corresponding tobacco leaf style characteristic index TQ, and reflects the style characteristics of tobacco leaves raw materials through the TQ index; TQ index calculation adopts Factors closely related to typical fragrant tobacco leaves and the weights of related factors, the calculation formula is:

[0017] TQ value = ∑ (positive correlation factor × weighting factor) / ∑ (negative correlation factor × weighting factor);

[0018] In the above formula, the positive correlation factor is an indicator that the content of typical fragrance-type tobacco leaves is higher than that of other varieties of tobacco leaves, and the negative correlation factor is an indicator that the conten...

Abstract

The invention relates to a method for representing style characteristics of tobacco by adopting characteristic indexes. The method comprises the steps that the characteristic chemical indexes of the tobacco are sifted and selected, the corresponding style characteristic indexes TQ of the tobacco are calculated, and the style characteristics of rhyme fragrance of raw materials of the tobacco are reflected through the TQ indexes; according to the computation of the TQ indexes, factors and related factor weight closely related to typical fresh scent tobacco are adopted, wherein the computational formula is: a TQ value=sigma(positive correlation factors*weight factors)/sigma(negative correlation factors* weight factors); the positive correlation factors are the indexes of the content higher than the other types of tobacco in the typical fresh scent tobacco, and the negative correlation factors are the indexes of the content lower than the other types of tobacco in the typical fresh scent tobacco; the typical fresh scent tobacco is tobacco Honghuadajinyuan; after the principal components of the tobacco is analyzed, the percentages of the characteristic values of all the principal components accounting for variance are the weight factors of the indexes closely related to the principal components; the larger the TQ value is, the more obvious the style characteristics of fresh scent are. The method has positive and important effects on scientifically identifying the style characteristics of the tobacco and effectively improving the use rate of the raw materials of the tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and relates to a method for characterizing the style characteristics of tobacco leaves. Background technique [0002] In the field of tobacco technology, to a certain extent, the category of tobacco raw materials is an important part of the construction of cigarette categories, and the quality and style of tobacco raw materials determines the trend of cigarette product categories. How to objectively and simply characterize and evaluate the style characteristics of tobacco leaf varieties is currently a hot research topic in the tobacco industry. [0003] In recent years, a large number of tobacco leaf grouping and quality studies have been carried out in the industry, but most of them are research on raw material grouping and processing technology and raw material quality analysis. few. Various existing methods have a certain positive effect on the quality evaluation of tobacco, but there are st...
