Abstract

The invention discloses a microbial compound inoculant and a preparation method and application thereof. The inoculant is prepared by mixing mould and yeast according to a weight ratio of (3-5):1. Themould is formed by mixing Aspergillus oryzae and Rhizopus oryzae according to a weight ratio of 1:(1-3); and the yeast is formed by mixing Saccharomyces cerevisiae, Hansenula anomala abnormal variant, Hansenula anomala and Wickerhamomyces anomalus according to a weight ratio of 1:(0.5-1.5):(0.5-1.5):(0.5-1.5). The fen-flavor liquor brewed by the microbial compound inoculant is pure in fen flavor,mellow, sweet, soft, natural, harmonious, refreshing in aftertaste, and high in liquor yield and high-quality liquor yield.

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to a microbial composite bacterial agent and its preparation method and application. Background technique [0002] Xiaoqu is a saccharification starter commonly used in the production of liquor. The key technology for making Xiaoqu is the selection of strains. The traditional Yangshao Xiaoqu is cultivated naturally. The types of microorganisms contained in Xiaoqu include: Rhizopus, Mucor, Aspergillus, Yeast, Bacteria etc. There are many kinds, and the rhizopus and yeast, which play a key role in brewing and fermentation, have low magnitude and purity, while other microorganisms such as bacteria reproduce and metabolize in the brewing process, and the wine yield decreases due to the consumption of starch in the raw grain to produce acid. [0003] The Chinese invention patent with the notification number CN106591160A discloses a production method of compound Xiaoqu and Xia...
