Abstract

In torder to explore the mechanisms of fermentative medium on the flavor enrichment and quality improvement of cigar tobacco leaves, the influence of fermentative medium on conventional chemical components, non-volatile organic acids, aroma components and microbial communities of cigar tobacco leaves was analyzed. The results showed that the contents of alkaloids in control group and experimental group decreased by 13.42% and 15.80%, respectively. The addition of fermentative medium delayed the degradation of alkaloids and reduced sugars in the early stage of fermentation. The organic acid composition in medium-group during 14~21 days was beneficial to improve the mellowness and reduce the stimulation of cigar tobacco leaves. The contents of aroma compounds and ketone aromatic compounds increased by 10.10% and 19.20% with the addition fermentative medium, respectively. During the fermentation process of 3 d, the content of aroma substances increased first and then decreased, indicating that excessive fermentation was not conducive to the accumulation of aroma components, and 21 days might be the optimal fermentation period. Fermentative medium could improve the diversity of microbial community in cigar tobacco leaves, and delay the succession rate of bacterial community. Besides, the succession of bacterial communities slowed down. As a result, the metabolic processes of alkaloids and sugars were changed, and the content of aroma components in cigar tobacco leaves increased so as to improve the quality of cigar.
