Abstract

The invention provides a method for analyzing aroma components in tobacco, which comprises the following steps: continuously heating a tobacco sample to be detected, enriching the aroma components in the tobacco by adopting a closed loop gas stripping method, performing thermal desorption, and performing qualitative and quantitative analysis by adopting a gas chromatograph-mass spectrometer. According to the method, the problem that the adsorption effect of the adsorbent becomes poor in the enrichment process can be effectively avoided, the method also has a good adsorption effect on the to-be-detected tobacco sample with the high moisture content, and the test of the aroma components in the tobacco is more accurate and effective.

Description

technical field

[0001] The invention relates to the field of tobacco, in particular to an analysis method for aroma components in tobacco. Background technique

[0002] The analysis of aroma components in tobacco is of great significance for the analysis of tobacco leaf style characteristics and the study of cigarette quality and style. The analytical methods routinely used in the prior art include solvent extraction, solid phase extraction, and headspace-solid phase microextraction. For the trace aroma components in tobacco leaves and smoke, the sensitivity of the above methods is still insufficient.

[0003] Closed-Loop-Stripping-Analysis (CLSA) is a closed-loop system in which a certain volume of gas circulates between sample bottles and enrichment tubes through an air pump and piping system. The component to be tested is continuously extracted and adsorbed in the enrichment tube by the airflow, which has the advantages of high concentration multiple, strong adsorption ...
