High content of lactic acid, low content of soybean antigen soya bean watse preparation method

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 ...

AI Technical Summary

Problems solved by technology

[0010] At present, the methods used by similar products of domestic manufacturers are: Fermentation method: three or more microorganisms are used for aerobic mixed fermentation, the fermentation process is difficult to control, and the quality of the final product is unstable, and for soybean balls with good thermal stability The removal effect of protein and other antigenic substances is not ideal; b. Enzymatic hydrolysis method: only use enzymatic treatment of soybean meal to remove anti-nutritional factors. Add acidifier
