Problems solved by technology

[0009] The disadvantage is that the preparation method uses a low-alkali method to extract rice bran protein. Chemicals are added in the preparation process, and the salts generated by the subsequent neutralization of lye need to be desalted, which makes the operation process complicated and increases the production cost. Time and cost, and may have a negative impact due to incomplete desalination

Abstract

The invention provides a feed additive containing a soybean immune peptide, a preparation method and application thereof. The method comprises the following steps of: crushing soybean meal or high-temperature denatured soybean meal serving as a raw material, sieving, and performing physical pretreatment on the raw material by an extrusion and expansion method; and crushing and sieving the extruded and expanded material again, performing enzyme hydrolysis, and spray-drying hydrolyzate to obtain a product prepared by the method. In the method, the source of the raw material is wide; chemical medicaments such as acid, base and the like are not required to be added in the preparation process, the enzymatic hydrolysis process is adopted, and conditions are mild, so the obtained product has higher immunocompetence, is low in cost, and has no toxic or side effect; and a protein or a polypeptide with better immune property and a corresponding additive product are obtained, so that the added value of the soybean meal is improved, and more products are provided for the development of the feed additive industry.

Description

technical field [0001] The invention relates to a feed additive and its preparation method and application, in particular to a feed additive with immune function containing soybean immune peptide and its preparation method and application. Background technique [0002] At present, due to the enhanced immune effect of immune additives has been widely recognized, immune additives for poultry and livestock are widely used. Common immune additives include both western medicine ingredients and traditional Chinese medicine ingredients, but there are problems to varying degrees. The presence of enhancers in varying degrees reduces the production performance of livestock and poultry, leading to the emergence of multi-drug resistant strains and residual contaminated livestock products, which in turn endanger human health. Therefore, a plant protein-derived immune additive came into being. On the one hand, it can activate the immune system, improve the proliferation of T lymphocytes, ...
