Fermented soybean meal with function of complex enzymes and preparation method for fermented soybean meal

Abstract

The invention discloses a fermented soybean meal with the function of complex enzymes and a preparation method for the fermented soybean meal. According to the invention, a mixed fermentation technology by multi-strains is adopted, non-transgenic soybean meal, microbial strain liquids, molasses and other raw materials are uniformly mixed and then subjected to solid-state fermentation, environmental conditions such as temperature, material moisture and the like in the processes of growth, metabolism and enzyme generation of microorganisms are controlled, so as to ensure the enzyme-generating capability of the microorganisms and enzyme preparation content accumulation during the fermentation process; after the fermentation is completed, the materials are dried at a low temperature. The fermented soybean meal prepared by the method disclosed in the invention contains a large amount of amino acids, active probiotics and other nutrients and has the greatest characteristic of being rich in different types of enzymes such as proteases, amylase, cellulase and xylanase, and is easily digested and absorbed by animals; the digestion and utilization rate of the fermented soybean meal is improved; the production cost is reduced.

Description

technical field [0001] The invention relates to the field of microbial fermentation and feed, in particular to a microbial solid-state fermentation method for producing compound enzyme function to produce fermented soybean meal with compound enzyme function, while preserving the beneficial microorganisms and nutrient components in the fermented soybean meal with maximum Increase the content of compound enzymes, enrich the beneficial nutrients in the fermented soybean meal products, improve the quality of the fermented soybean meal products, and improve the feeding effect of the products. Background technique [0002] With the improvement of people's living standards, people's demand for livestock products is increasing, which has led to the rapid development of the breeding industry and the feed industry. At the same time, the following issues have attracted much attention: one is the problem of feed resources; Environmental issues in animal husbandry. At present, the way t...

Problems solved by technology

However, the current compound enzymes are generally compounded from a single enzyme, and the cost is high, and most of them only point out the optimal dosage of the enzyme preparation as a whole. There is no scientific basis for the amount of various enzymes added, just blind Added, and did not take into account the interaction effect between single enzymes, and there is very little research on the appropriate ratio between them
