Abstract

The invention discloses liquid compounding enzyme for brewage, and a preparation method of the liquid compounding enzyme, and belongs to the technical field of liquid compounding enzyme preparation. A liquid enzyme preparation for the brewage serves as a main raw material, stabilizing agents such as sugar, polyhydric alcohol, amino acid, a thickening agent, albumin and a metal ion and substances with preservative effects such as a hop extract promoting stabilization of the enzyme preparation, a Chinese herbal medicine extracting solution and antibacterial peptide are scientifically compounded, addition of a preservative is completely substituted, reproduction and growth of a harmful microbe are restrained effectively, and the activity of the liquid compounding enzyme can be cooperatively stabilized with other components, so that the biological stability and the enzyme activity stability of the liquid compounding enzyme are improved fundamentally, and the quality guarantee period of the liquid enzyme preparation is prolonged effectively. The aerobic bacterial count after the prepared liquid compounding enzyme is stored for 12 months at a room temperature is 168-214CFU/mL, and enzyme activity loss ratios after the liquid compounding enzyme is stored for 12 months at 40 DEGC and 0 DEG C are 2-2.5% and 1-1.7% respectively.

Description

technical field [0001] The invention relates to a liquid compound enzyme, in particular to a liquid compound enzyme for beer brewing and a preparation method thereof. Background technique [0002] Liquid enzyme preparation is a raw material that is easy to use, environmentally friendly and has good biodegradability. Specific catalytic properties and mild reaction conditions have been more and more used and valued in the industry. In terms of use, liquid enzyme preparations have the following advantages: 1) Liquid enzyme preparations are dispersed in the substrate in the form of molecules or particles, with large dispersion, fast absorption, rapid enzymolysis reactions, and high enzyme activity; 2) easy separation Dosage, easy compounding and secondary processing, easy to use; 3) It is beneficial to improve the utilization rate of enzyme preparations, 4) It can be used directly without dissolution and activation; 5) High purity and low impurity content; 6) Short production p...
