Abstract

The invention relates to bioactive pit mud and a preparation method thereof. The bioactive pit mud which has rich and pure pit mud smell and thick ester aroma is prepared by carrying out fermentation on the raw materials such as a pit mud culture solution, by-products obtained in liquor-making, yeast for making hard liquor, fresh apples, pears, soybean cake powder, roasted soybeans, sesame seeds as well as functional bacteria and nutrient salts for a long time. The bioactive pit mud contains rich and eugonic liquor-making microbes, is harmonious in nutritional ingredients, provides a microbial source for making liquor, and is more beneficial to implementation of polymicrobial co-fermentation.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a bioactive pit mud and a preparation method thereof. Background technique [0002] The pit mud is the basis in the liquor brewing process, and the quality of the pit mud directly determines the quality of the wine. The microorganisms in the pit mud, such as caproic acid bacteria, Clostridium and other beneficial functional microorganisms for wine making, can metabolize caproic acid , acetic acid, butyric acid and other liquor aroma substances precursor. The use of pit mud culture fluid in the production process of liquor can enrich and coordinate the beneficial functional microbial strains in pit mud and fermented grains, increase the content of ethyl caproate in Luzhou-flavor liquor, and improve the quality of liquor. The type and quantity of beneficial microorganisms are a standard to measure the quality of pit mud. However, the pit mud prepared by the general production met...
