Method for producing forage plant protein by carrying out enzyme synergy fermentation and enzymolysis on plant protein

Abstract

The invention relates to a method for producing a forage plant protein by carrying out enzyme synergy fermentation and enzymolysis on a plant protein. The method is characterized in that enzyme for the fermentation and the enzymolysis comprises a complex enzyme preparation and microbial strains; a plant protein raw material for the fermentation and the enzymolysis is extracted from residual processed meal or grains after two or more kinds of plant seeds are compressed or fermented. The method comprises the steps of preparing the materials, inoculating and mixing the materials, carrying out the fermentation, carrying out the enzymolysis, drying, cooling, crushing and carrying out product detection, so as to finally obtain a forage plant protein product, wherein the content of small peptide of the forage plant protein product is 10-40% of that of the proteins of the forage plant protein product. The method has the advantages that the key technical problems of high labor intensity, difficulty in control, instable quality, low production efficiency, high energy consumption and the like in the solid state fermentation process of the plant proteins can be solved, the industrialization of a fermented plant protein product can be effectively promoted, and the economic benefit can be increased.

Description

technical field [0001] The invention relates to a method for producing forage plant protein by enzymolyzing plant protein through co-fermentation with enzyme bacteria, which belongs to the field of bioengineering. Specifically, it is an industrial engineering technology that uses the combined enzyme preparation, Bacillus subtilis BZD-01, and brewer's yeast BZD-02 to convert plant protein into fermented and enzymatically hydrolyzed technology to produce high-quality protein for feed. Background technique [0002] 1. Feed farming industry’s demand for high-quality plant protein: [0003] Feed farming is one of the pillar industries in many countries, so the total demand for feed is huge; [0004] The development of the feed industry must rely on high-quality raw materials, especially protein raw materials. But there are following problems: [0005] (1) The shortage of animal protein resources and the existence of safety problems; [0006] (2) Soybean meal cannot meet the d...
