Pit mud compound functional bacterial liquid and preparation method thereof

Abstract

The invention discloses pit mud compound functional bacterial liquid and a preparation method thereof. Based on 100 percent of grain-distilled immersion liquid, the pit mud compound functional bacterial liquid comprises the following components in percentage by weight: 5 to 8 percent of pit mud, 2 to 3 percent of soybean oil meal, 1 percent of yeast for making hard liquor meal, 0.3 to 0.5 percent of K2HPO4, 0.2 to 0.3 percent of NaAC, 0.01 to 0.02 percent of MgSO4, 2 to 4 percent of 95 percent alcohol and 5 to 15 percent of discolored water. M-type microorganisms are taken as a main material in the pit mud compound functional bacterial liquid obtained by the formula and a process provided by the invention, and the pit mud compound functional bacterial liquid contains a certain number of spore bacteria such as caproic acid bacteria, butylic acid bacteria and the like, has the functions of adjusting the pH value of the pit mud and generating fragrant substances such as caproic acid and the like, is used for curing degraded pit mud with a low pH value and can remarkably improve the quality of white spirit.

Description

technical field [0001] The invention relates to the technical field of liquor brewing, in particular to a pit mud composite functional bacterial liquid and a preparation method thereof. Background technique [0002] Luzhou-flavor Daqu liquor is a unique traditional distilled liquor in China. Its quality mainly depends on the quality of pit mud, koji-making process and wine-making process. The existing technology can fully meet the requirements of koji-making process and wine-making process, while pit mud It is quite difficult to achieve the quality of high-quality pit mud, and it often takes decades or even hundreds of years for traditional high-quality pit mud to form naturally. Since the 1960s, my country has carried out a lot of research work on pit mud research, and has achieved major scientific research achievements such as artificial pit mud. However, the problem that artificial pit mud is easy to degrade during use has long plagued all Luxiang A large-scale Daqu liquo...
