Fermentation is an important process to form the flavor characteristics of cigar leaves.The surface of cigar leaves is accompanied by active microbial activities,and the substances are further degraded and transformed to form aroma substances related to flavor.The flavor evaluation system of cigar tobacco leaves,flavor characteristics of cigar tobacco leaves at home and abroad,flavor substances basis of cigar tobacco leaves,and changes of flavor substances during the fermentation process were overviewed.The effects of microbial flora and enzyme activity in cigar tobacco leaves fer-mentation on the flavor formation of cigar tobacco leaves were summarized.The method to improve the flavor quality of cigar tobacco leaves by arti-ficial fermentation technology(exogenous materials,exogenous microbes,exogenous enzymes and physical regulation,etc.)were described,and the development direction of cigar tobacco leaves flavor research technology was prospected,which was of great significance to realize directional ad-justment of domestic cigar tobacco leaves flavor quality.
