Abstract

The invention relates to a method for screening style characteristic components of tobacco source spice, which belongs to the technical field of tobacco spice. The method comprises the six steps of sample collection, sample chromatographic analysis, sample sensory evaluation, pretreatment, Mann-Whitney-Wilcoxon inspection and variable screening. According to the method, components capable of highlighting specific style characteristics of cigarettes are screened on the basis of the frequency ratio X, the style characteristics of the tobaccos as an effect basis and high performance liquid chromatography original data and main chemical component data of the tobaccos as a component basis. The method points out the direction for the preparation work of the spice with the highlighted sensory style. The screened characteristic components are applied to development of the tobacco source characteristic spice, the sensory evaluation result is excellent, and good practical significance is achieved.

Description

technical field [0001] The invention belongs to the technical field of flavors for tobacco, and in particular relates to a method for screening characteristic components of flavors derived from tobacco leaves. Background technique [0002] With the development of low-tar cigarettes, problems such as lack of mouthfeel and reduced aroma brought by low-tar cigarettes have become increasingly prominent. How to make up for the lack of cigarette smoking quality caused by low coking has become a hot research direction in the tobacco industry. In the industry, there are endless research results in the development of flavors and fragrances for cigarettes from natural aromatic plants, microbial derivative fermentation, and tobacco itself. For tobacco-derived spices, on the one hand, it has the effect of supplementing the characteristic aroma of tobacco and penetrating the original aroma of tobacco. Through different technological means, such as molecular distillation, membrane chrom...
