Preparation method and application of brewing enhanced bacterial source

Abstract

The invention provides a method for preparing wine making reinforcement bacterium sources and application thereof. The method includes steps of A, preparing cultivation media, to be more specific, mixing medium bran, fermented grains and water with one another to obtain mixtures, regulating the mixtures until the PH (potential of hydrogen) of the mixtures reaches 6.5, sterilizing the mixtures and cooling the mixtures until the temperatures of the mixtures reach 35 DEG C to obtain the cultivation media; B, gathering bacteria in pit mud, to be more specific, cultivating the high-quality aged pit mud in the cultivation media obtained at the step A at the temperature of 32-35 DEG C for 100-150 days, then fetching the cultivation media with large quantities of gathered microbial bacterial colonies and drying the cultivation media to obtain first-grade bacteria; C, carrying out fractional enlarged cultivation on the first-grade bacteria obtained at the step B and then drying the first-grade bacteria, the bacterial colonies and the cultivation media to obtain the wine making reinforcement bacterium sources. The method for preparing the wine making reinforcement bacterium source and the application have the advantages that the method is simple, chemical reagents can be omitted, the wine making reinforcement bacterium sources are applied to parent grains, new pit mud cultivation and rejuvenation and reinforcement of degenerated microorganisms in pit mud, microbial bacterial colonies in original environments can be quickly reinforced, and accordingly the quality of wine can be improved.

Description

technical field [0001] The invention relates to a wine-making strengthening bacterial source used in wine-making, in particular to a preparation method and application of a wine-making strengthening bacterial source, and belongs to the technical field of liquor brewing. Background technique [0002] At present, the majority of Luzhou-flavor winemaking enterprises mainly improve the quality of pit mud through the following two methods: First, adopt traditional pit mud cultivation and maintenance methods, that is, use winemaking resources to cultivate pit mud artificially, and rely on traditional winemaking techniques to carry out pit pit mud quality. Conservation, through multiple rounds of fermentation, gradually improve the quality of pit mud. This method is effective on the whole, but the pit mud has a longer maturity period and is slower. Second, by putting caproic acid bacteria culture solution into the pit mud to increase the content of the main functional bacteria-cap...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the complicated operation process of the preparation method in the prior art, and the addition of various chemical reagents and the content of a certain kind of pit mud functional bacteria in the preparation process will break the balance of the original microbial community during use. growth, it is difficult to exert a good synergistic effect, and a kind of wine-making strengthening bacteria source and its preparation method are provided. Mud culture, rejuvenation and enhancement of microbial degradation in pit mud, and adding wine-enhancing bacteria sources to mother's grains can quickly strengthen the microbial flora in the original environment, thereby improving the quality of wine
