Abstract

The invention relates to a method for producing high lysine fermented soybean meal. The method comprises the following steps: a, preparing a soybean meal raw material; b, adding water into the soybean meal raw material and stirring up uniformly to obtain aqueous soybean meal slurry; c, carrying out germicidal treatment for the aqueous soybean meal slurry obtained from step b; d, adding urea and ammonium sulphate into the aqueous soybean meal slurry treated through step c, and stirring up uniformly to obtain a soybean meal culture medium; e, accessing microbial strains capable of generating lysine into the soybean meal culture medium obtained from step d; f, conducting temperature control fermentation for the soybean meal culture medium treated through step e to obtain fermented soybean meal; and g, drying the fermented soybean meal to obtain the final product. The invention has the advantages that the preparation method brings out an apparent increase in the nutrient substances present in the fermented product with the content of soybean meal protein rising by more than 5%, and an obvious boost in the content of lysine, which increases to over 4.0% under the action of microzyme, from an initial 2.8%.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a production method of high-lysine fermented soybean meal. Background technique [0002] Amino acids are the basic units that make up proteins. The protein contained in the feed cannot be directly digested and absorbed by the animal. It must be decomposed into amino acids through the action of enzymes before it enters the blood through the digestive system and recomposes its own protein in the animal body. Therefore, the animal's need for protein is actually the need for amino acids. [0003] Amino acids can be divided into two categories, one is essential amino acids, and the other is non-essential amino acids. Any amino acid that can be synthesized by itself in animals and not necessarily ingested from feed is called non-essential amino acid. Those that cannot be synthesized or synthesized in the body cannot meet the nutritional needs of animals, but are esse...
