Abstract

The invention relates to a method for screening sensory quality characteristic components of tobacco-derived spice, and belongs to the technical field of tobacco spice. The method comprises the following six steps: sample collection, sample chromatographic analysis, sample sensory evaluation, pretreatment, Mann-Whitney-Wilcoxon inspection and variable screening. According to the method, componentscapable of highlighting the specific quality characteristics of the cigarettes are screened on the basis of the frequency ratio X, the quality 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 prominent sensory quality. The screened characteristic components are applied to development of the tobacco-derived 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 screening method for the sensory quality characteristic components of tobacco leaf flavors. Background technique [0002] In order to keep the quality of cigarette products relatively stable, while rationally designing the leaf group formula, it is also necessary to overcome flavor defects by adding tobacco flavor and fragrance substances, that is, adding flavor is also an important measure to improve product quality. Generally, according to the source of spices, they can be divided into two categories: natural spices and synthetic spices. At present, there are more than 3,000 known natural spices and more than 7,000 synthetic spices, and new varieties are still emerging. Among them, the spices developed from the origin of tobacco leaves have always been considered as the best product with the best coordination with smoke. [0003] Tobacco-derived spice...
