Abstract

The invention provides a thermal desorption-gas chromatography-mass spectrometry fingerprint analysis method of fragrance and flavor for tobacco, comprising the following steps: using the thermal desorption technique during pre-processing the fragrance and flavor for tobacco; using a gas chromatography-mass spectrometry to analyze; establishing a digital fingerprint of sample; judging the similarity of the sample and standard sample by the cosine and euclidean distance method. The thermal desorption technique greatly simplifies the pre-processing operation process and ensures the reliability and stability of the experiment result, and introduces the volatile components into the gas chromatography, in order to conquer the defect of the prior technique that: all the components dissolved in the extraction solvent are introduced into the gas chromatography and the pollution on the instrument is reduced and the service life of the instrument and chromatographic column is prolonged. The analysis method provides a reliable, stable, quick and new method for controlling the quality of the fragrance and flavor for tobacco.

Description

technical field [0001] The invention belongs to the field of flavors and fragrances for tobacco, and relates to a thermal desorption-gas chromatography-mass spectrum fingerprint analysis method for flavors and fragrances for tobacco. Process the data to characterize the composition characteristics of tobacco flavors and fragrances, so as to realize the quality control of tobacco flavors and fragrances. Background technique [0002] In the production process of cigarettes, in order to improve the smoking quality of cigarettes, it is necessary to use various flavors for tobacco. Tobacco flavor is a mixture made of various spices and an appropriate amount of solvent. Due to the influence of various factors such as raw material origin and processing technology, the product quality has certain fluctuations. Therefore, the stability of the quality of tobacco flavors has attracted widespread attention from flavor manufacturers and cigarette companies. At present, most cigarette m...
