Research progress of microbial community and flavor substances in strong-flavor Baijiu pit mud
Pit mud plays an important role in the production of strong-flavor(Nongxiangxing)Baijiu,and its microbial community type,structure and metabolites have important effects on the flavor of the Baijiu.In order to reveal the effect of pit mud on the formation of flavor substances of strong-flavor Baijiu,the lactic acid bacteria,caproic acid bacteria,Bacillus and methanogenic bacteria in the pit mud were briefly introduced,the volatile flavor substances in strong-flavor Baijiu were summarized,and the effect of microbial flora in the pid mud on the volatile flavor substances of strong-flavor Baijiu was discussed.This study was helpful to further understand the role of microbial community in shaping flavor characteristics of strong-flavor Baijiu,and provide reference for brewing industry workers.
