Method for detecting quality of tobacco flavor

Abstract

The invention provides a method for detecting the quality of tobacco flavor. The method provided by the invention comprises the following steps of: classifying a tobacco flavor sample to be detected according to a sensory evaluation result to obtain three classes of flavor samples; carrying out main component analysis on the obtained chromatograph data of the tobacco flavor samples, combining the obtained main component analysis result with the sensory evaluation result, and dividing components contained in the tobacco flavor to five classes according to a variation condition of components in the tobacco flavor and relevance of the main component analysis result and the sensory evaluation result; analyzing the chromatograph analysis data of the tobacco flavor by using a clustering methodology according to the obtained classification result of the sample and the obtained classification result of the components of the tobacco flavor; and directly obtaining the quality variation condition of the tobacco flavor according to the obtained clustering analysis result. The method provided by the invention is simple to operate; and furthermore, the problems that a detection result in a manual smoke test process is influenced by a level, physical states, environmental factors and the like of a smoke tester can be solved.

Description

technical field [0001] The invention relates to the technical field of cigarette quality monitoring, in particular to a method for detecting the quality of tobacco essence. Background technique [0002] The purpose of flavoring cigarettes is to eliminate the differences between different grades of tobacco leaves, purposely increase and enhance other flavors, and make the flavor more full; reduce the dry feeling of cigarettes during the smoking process, eliminate roughness, increase their sweetness, and improve smoking. taste. Flavoring cigarettes endows cigarettes with characteristic flavors (smelling aroma, pack-opening aroma, smoking style), which increases the appeal to consumers; and proper flavoring can enhance the grade of cigarettes to a certain extent. In addition to making cigarettes have a beautiful and pleasant smell, the flavoring essence for tobacco should also have a good flavoring effect in the burned mainstream smoke and sidestream smoke.

Problems solved by technology

However, when the characteristic spectrum or principal component analysis method is used to judge the quality stability of the compound tobacco flavor with different storage periods, there are some differences between the analysis results and the sensory evaluation results, and the accuracy of the results is low, which limits the quality of GC.
