Embodiment 1

[0021] Use soybean meal as raw material, mix it with water according to the ratio of material to water of 1:0.2 and stir evenly, then sterilize at a temperature of 100°C to 125°C; after sterilization, add 40wt% lactic acid bacteria and 40wt% Saccharomyces cerevisiae. And add 3wt% protease according to the weight of soybean meal, stir evenly, ferment enzymolysis at 28-45 DEG C; ferment time is 24 hours; dry and cool down after fermenting.

Embodiment 2

[0023] Using soybean meal as raw material, mix it with water according to the ratio of material to water of 1:0.6 and stir evenly, then sterilize at a temperature of 100°C to 125°C; after sterilization, add 35wt% lactic acid bacteria and 35wt% lactic acid bacteria according to the weight of soybean meal Saccharomyces cerevisiae. And add 3wt% protease according to the weight of soybean meal, stir evenly, ferment and enzymolyze at 30-45 DEG C; ferment time is 24 hours; dry and cool down after fermenting.

Embodiment 3

Abstract

A preparation method of bean pulp with high lactic acid content and low soybean antigen; with the method, the beam pulp is taken as the raw material and sterilized after being mixed with water evenly; microbe bacteria are inoculated on the beam pulp after sterilization and 3 to 5 wt percent enzyme preparation is added and mixed evenly for fermentation and enzyme digestion with a temperature from 28 to 45 Celsius degrees; drying and cooling processes are implemented after fermentation. The fermentation process with the present invention is easy to be controlled and the quality of obtained product is stable. The degradation rate of the harmful oligose (stachyose and raffinose) is more than 99 percent; the bean antigen protein is totally degraded; the protein content is increased by more than 3 percent and the lactic acid content is more than or equal to 5 percent; the prepared plant protein feed can be used for feeding animals and increasing the digestion and absorption capability of animals; in addition, the feed can be used for adjusting the micro-ecological balance inside of animals and enhancing the capability of preventing and resisting disease.

Description

technical field [0001] The invention relates to the technical field of plant protein feed processing, in particular to a method for preparing soybean meal with high lactic acid content and low soybean antigen by using soybean meal as a main raw material and adopting a solid-state fermentation process. Background technique [0002] Early weaning of young animals is due to imperfect digestion, low immunity, and physiological, nutritional and environmental stress after weaning. Diarrhea often occurs after weaning. The mild ones affect the growth and development of young animals, and the severe ones cause Death caused huge losses to breeding production. [0003] At present, in the breeding industry, there are serious problems in the use of feed resources; animal feed resources are scarce and the price is relatively expensive; plant feed, especially plant protein feed, although the cost is low, but there are anti-nutritional factors to varying degrees , not only affects protein ...
