Abstract

The invention relates to high-acid and high-peptide fermented soybean meal and a preparation method thereof and belongs to the technical field of biological fermentation. The preparation method includes: evenly mixing, by weight, 100 parts of water, 10-30 parts of soybean meal, 0.1-0.2 part of a pH regulator, 0.3-0.8 part of sodium acetate and 0.2-0.6 part of a trace element supplement; inoculating, by weight, 1-10 parts of lactic acid bacterium seed solution and 1-10 parts of mould seed solution, and performing aerobic diastatic fermentation to obtain diastatic fermentation liquor; evenly mixing, by weight, 100 parts of soybean meal, 40-60 parts of diastatic fermentation liquor, 0.2-0.4 part of protease and 1-10 parts of bacillus seed solution, regulating water content to be 30-45%, and performing solid-state fermentation to obtain a solid-state fermentation product. The method has the advantages that saccharification and fermentation are performed at the same time, the diastatic fermentation liquor contains a large number of diastatic enzymes and lactic acid, and the diastatic fermentation liquor is inoculated into the soybean meal to perform solid-state fermentation; a large amount of protease and organic acid can be generated during the solid-state fermentation, and the total acid content and small peptide content of the fermented soybean meal are high.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a high-acid and high-peptide fermented soybean meal and a preparation method thereof. Background technique [0002] Soybean meal is a by-product obtained after extracting soybean oil from soybeans. It is a very high-quality raw material for livestock and poultry plant protein feed. Protein in soybean meal accounts for 40-44%, fat accounts for 1-2%, carbohydrate accounts for 10-15%, and contains a variety of minerals, vitamins and essential amino acids, and occupies a large proportion in livestock and poultry diets. The soybean meal fermented by microorganisms has high content of small peptides and rich metabolites, which effectively improves the digestion and utilization rate of soybean meal. At present, the process of fermented soybean meal produced by fermented soybean meal manufacturers is relatively simple, the antigen degradation after fermentati...
