Abstract

The invention discloses a Baijiu-brewing compound enzyme containing acid protease and a preparation method of the Baijiu-brewing compound enzyme containing the acid protease and belongs to the technical field of compound enzyme preparation. The Baijiu-brewing compound enzyme containing the acid protease and the preparation method have the advantages that on the basis of scientific compounding of food-grade enzyme preparations, high-activity acid protease and plant extracts containing plant enzymes and nutrient substances are compounded specially to enable an enzyme system of the compound enzyme to be more complete; activating agents enabling enzyme activity to be completely released and protective agents and antioxidants enabling enzyme activity to be more stable are added, and esterified red yeast and aroma-producing active dry yeast which make Baijiu more sufficient in aroma are compounded scientifically, so that starch, protein, fat, cellulose, hemicellulose, pectin and the like in grain can be hydrolyzed sufficiently and effectively, Baijiu yield can be increased by 24% to 29% remarkably, total ester content can be increased from 16.59% to 57.85%, and ethyl acetate content can be increased from 17.9% to 109%; taste of various types of Baijiu can be improved remarkably, and the compound enzyme can be suitable for brewing various types of Baijiu and addition of different Baijiu brewing methods.

Description

technical field [0001] The invention relates to a compound enzyme, in particular to a liquor brewing compound enzyme containing acid protease and a preparation method thereof. Background technique [0002] With the change of people's consumption concept, the current liquor consumption group pays more attention to the taste of liquor products. In view of the multi-level, multi-category, and diversity of liquor consumption needs, in order to meet the ever-changing consumer demand, it is necessary to continuously innovate product personality and characteristics. The main research and development directions are soft and sweet in the mouth, round and comfortable in the throat, comfortable after drinking and with few side effects. The main raw material for wine making in my country is sorghum. Sorghum winemaking is a process in which the starch in the grains is converted into sugar by the action of enzymes produced by microorganisms, and then alcohol is produced. Microorganisms...
