Xiaoqu liquor is a type of distilled spirit in China prepared on a small scale from a small solid starter culture. To improve the flavor profile of Xiaoqu liquor, we selected two functional yeast strains (Saccharomycopsis fibuligera and Saccharomyces cerevisiae) from Zaopei (fermented grain) of Baijiu liquor and used them for Xiaoqu liquor fermentation Compared with traditional Xiaoqu (Starter), bioaugmentation inoculation increased the glucoamylase and acidic protease activities and the ethanol synthesis rate, while decreasing the acidity of the Zaopei (fermented grains) in the early stage of fermentation By the end of the fermentation process, the alc. and ester content had also increased by 42.5% and 11.8%, resp., and that of aldehydes and ketones, and heterocyclic compounds decreased by 73.7% and 77.1%, resp. The dominant fungus during fermentation using the two types of starter cultures was S. cerevisiae, whereas the dominant bacteria was Pseudomonas, followed by Bacillus, Weissella, Lactobacillus, and Bacteroides. Principal component anal. of the bacterial community structure and flavor substances in the Zaopei produced using the two strains revealed that there were few differences between the two liquors and that inoculation with functional yeasts may not change the flavor substances in Xiaoqu liquor. However, correlation anal. showed that Escherichia Shigella, Terrisporobacter, Bacillus, Clostridium, and Prevotellaceae are the main microorganisms in the Xiaoqu liquor fermentation process.
