Abstract
The invention provides a method for detecting volatile components of tobacco leaves in a curing barn. The method comprises the following steps: sample preparation, gas phase mass spectrometry detection, enrichment time and reagent optimization and the like, gas in the curing barn is enriched, a volatile gas in the curing barn is analyzed through GC-MS, and an optimal extraction reagent and optimal extraction time are determined; and volatile components at different temperature points in the tobacco leaf curing process are studied, OAV is calculated, compounds with high aroma activity values in a volatile gas in the curing barn are determined, 13 key aroma compounds in the volatile components of the tobacco leaves in the curing barn are preliminarily identified, and therefore an effective detection method is provided for improving tobacco leaf quality identification.
Description
technical field [0001] The invention relates to the field of tobacco quality detection, in particular to a method for detecting volatile components of tobacco leaves in a curing barn. Background technique [0002] Tobacco is one of the most widely planted economic crops in the world, the main raw material of the cigarette industry, and the quality of tobacco leaves seriously affects the quality of cigarette products. However, densely cured tobacco leaves tend to be green, smooth and thin, and it is difficult to meet the needs of high-quality Chinese cigarette raw materials. Therefore, optimizing the curing process and improving the quality of tobacco leaves has become an urgent problem in tobacco leaf production. [0003] Curing is a key link in cigarette production. During the curing process, temperature and humidity determine the chemical or biological changes of the internal components of tobacco leaves. For example, the aroma precursors in tobacco leaves are cracked or ...
