Abstract

The invention discloses a special enzyme for hydrolyzing animal protein and a preparation method thereof, belonging to the technical field of enzyme preparations. The special enzyme for hydrolyzing animal protein includes the following raw materials in weight percent: 8-12% papain, 8-12% bromelain, 4-7% nuclease, 8-12% flavor enzyme, 18-18% table salt 22%, Trehalose 4‑7%, Glucose 35‑45%. The invention combines a variety of natural biological enzymes according to a certain ratio, and is a compound special enzyme product for animal protein hydrolysis that can be hydrolyzed according to different raw materials of animal food by-products and different treatment processes. Utilize the present invention to hydrolyze all kinds of animal proteins, and by controlling the degree of hydrolysis, the required polypeptides, small peptides, and amino acid products can be obtained, so that the yield, solubility, flavor, and taste of the products can reach new product grades, satisfying people's various needs. need.

Description

technical field [0001] The invention relates to the technical field of preparation of enzyme preparations, in particular to a special enzyme for hydrolyzing animal protein and a preparation method thereof. Background technique [0002] Animal food is an important nutritious food in people's daily life, and it is also an important raw material for the food industry. People hope to fully obtain the nutritional content of animal food by-products, improve the utilization value of animal by-products, turn waste into wealth, and create higher economic and social benefits. Therefore, the energy consumption, safety, processing efficiency, hydrolysis degree, and nutrient retention degree of animal food hydrolysis are important indicators reflecting the hydrolysis of animal food and determine the quality of animal protein hydrolysis. [0003] The traditional processing of animal food generally adopts the acid-alkali method, which has the disadvantages of residual chemical components,...
