Embodiment Construction

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

[0014] The main advantage of fingerprint is that it can reflect the uniformity and stability of the inherent quality of plant materials and their preparations with complex components. The quality of tobacco leaves has obvious differences due to the ecological environment, grade, location and aging time of the producing area. The fingerprint pattern not only has the "commonality" for judging the authenticity of the object, but also reflects the characteristics of the difference brought 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 have proposed using the iodine value method to judge the alcoholization process of tobacco leaves, but this method is still far from the actual application of production. These studies only provide the feasibility of applying non-sensory metho...

Abstract

The invention relates to a high-efficiency liquid-phase fingerprint 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 using Chinese-herb fingerprint software, and establishing a regression relation model between the total area of the fingerprint characteristic peak and the organoleptic quality of the tobacco samples; by using the organoleptic quality as the dependent variable y and using the fingerprint total area x as the independent variable, establishing the regression relation model: Y=72.04974+0.1388*LN(X)*LN(X) or Y=X/(0.011081*X+13.247); and calculating the organoleptic quality Y according to the fingerprint total X of the measured samples. The method has the characteristics of high accuracy, favorable stability and convenient operation, can save lots of human resources, physical resources 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 aging quality of flue-cured tobacco, in particular to a high-performance liquid phase fingerprint analysis method for determining the aging quality of flue-cured tobacco. Background technique [0002] Tobacco aging is an important part of cigarette production, and it is also an important step to improve the quality of tobacco smoked food. It plays a very important role in improving the quality of finished cigarettes 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, which leads to changes in internal chemical components, which in turn leads to the improvement of tobacco leaf quality. [0003] The chemical components in tobacco leaves are the internal factors that determine the quality of tobacco leaves. The chemical components of tobacco leaves mainly include: carbonyl compou...
