Abstract

Abstract: In order to study the changes of aroma components under different conditions of threshing and redrying,the differences of aroma components of C3F grade Cuibi No.1 tobacco leaves before and after redrying were analyzed by simultaneous distillation and extraction combining with GC/MS.Results showed that,leaf threshing and redrying had significant effect on the content of aroma substance;After redrying,the content of aroma substance increased,and the increase was the largest at high leaf threshing strength and low redrying strength;The increase of fatty acids,phenols,alcohols,nitrogen-containing heterocycles and esters was higher than that of the total amount of fragrance substances,while the increase of furans,aldehydes and ketones was lower than that of the total amount of fragrance substances.High intensity threshing and low intensity redrying are beneficial to the transformation and retention of aroma components and improve the sensory quality of tobacco.

Key words: threshing and redrying, processing strength, aroma component
