Problems solved by technology

However, since the factors affecting the smoking quality of tobacco leaves are caused by the complex balance of chemical components, the use of chemical indicators to judge the alcoholization quality of tobacco leaves seems single and one-sided; however, there is no widely applicable chemical analysis and instrumental analysis methods at present. , which limits the application in production

Embodiment Construction

[0013] The present invention is further illustrated by specific implementation examples.

[0014] The advantage of fingerprints is mainly that it can reflect the uniformity and stability of the inherent quality of plant materials with complex components and their preparations. The quality of tobacco leaves is significantly different due to the ecological environment, grade, location and aging time of the producing area, while the fingerprints not only have the "commonness" to judge the authenticity of the object, but also can reflect the differences brought about by the influencing factors. The uniqueness of species and the similarity of individuals can reflect the quality of tobacco leaves as a whole.

[0015] In the past, we proposed to use the iodine value method to judge the aging process of tobacco leaves, but this method is still far from the needs of practical application in production. These studies only provide the feasibility of using non-sensory methods to judge the...

Abstract

The invention relates to a high-efficiency liquid-phase fingerprint main-component analytical method for judging the alcoholizing quality of flue-cured tobacco, which comprises the following steps: measuring different tobacco samples by using a high-efficiency liquid-phase chromatogram analytical method to obtain a tobacco fingerprint characteristic peak, analyzing the characteristic peak by usingChinese-herb fingerprint software, and establishing a multivariate regression relation model between the main component values of the characteristic peak and the organoleptic quality of the tobacco samples; by using the organoleptic quality Y as the dependent variable and using the seven main component values A1 to A7 as the independent variables, establishing the regression relation model between the main component values of the characteristic peak and the organoleptic evaluation values: Y=85.64+1.34A1+1.21A2+0.27A3-0.40A4-1.17A5-0.46A6+0.48A7; and calculating the organoleptic quality Y according to the main component values A obtained by analysis. The method has the characteristics of high accuracy, favorable stability and convenient operation, can save lots of human resources, physicalresources and financial resources in the actual operation, and can completely replace the traditional organoleptic evaluation method for judging the alcoholizing quality of the flue-cured tobacco.

Description

technical field [0001] The invention relates to a method for analyzing and judging the alcoholization quality of flue-cured tobacco, in particular to a high-performance liquid phase fingerprint principal component analysis method for judging the alcoholization quality of flue-cured tobacco. Background technique [0002] Alcoholization of tobacco leaves is an important link in cigarette production, and it is also an important step in improving the smoking quality of tobacco leaves. It plays a very important role in improving the quality of finished cigarette products and strengthening cost control. During the aging process, a series of complex physiological, biochemical and pure chemical changes occur inside the flue-cured tobacco sheet, leading to changes in the internal chemical components, which in turn lead to the improvement of the quality of the tobacco leaves. [0003] The chemical components in tobacco leaves are the internal factors that determine the quality of toba...
