Abstract

The invention discloses a process for preparing protein powder by a protease and peptidase hydrolysis method. The process is as follows: (1) taking a silk substance, deionized water, protease and peptidase in the material mass ratio of silk substance: deionized water: protease: peptidase of 1:25-50:1:1 for ultrasonically stirring and mixing evenly; (2) heating to 20-80 DEG C, and continuing to ultrasonically stirring for 2-5h with the ultrasonic power of 200-500W to promote silk protein hydrolysis under silk protein hydrolysis conditions of 40-60 DEG C water bath; and (3) adding sodium carbonate into the solution, vibrating, centrifuging, drying under vacuum at 40-60 DEG C, and repeating grinding and ball milling a plurality of times to obtain the protein powder.

Description

technical field [0001] The invention relates to protein powder food, in particular to a process flow for preparing protein powder by hydrolysis with protease and peptidase, and belongs to the technical field of food processing. Background technique [0002] Protein is one of the seven essential nutrients for the human body. The human body ingests animal protein and plant protein through daily animal food and plant food. With the increasing awareness of people's health and the improvement of income levels, the normal diet can no longer meet the demand for protein quality, nor meet the consumption requirements of people's healthy diet. Therefore, people process protein-containing animal foods or plant foods to extract high-purity protein raw materials, which are widely used in food, medicine, health care products and other industries for production and processing. Protein intake in a healthier way. Protein is the most important nutrient to ensure the health of the body. It ...
