Embodiment Construction

[0008] The present invention will be further described below in combination with embodiments.

[0009] The preparation method of this feed additive animal growth-promoting peptide uses rice protein (commonly known as monosodium glutamate slag, which is the discarded protein after the monosodium glutamate is fermented and produced by monosodium glutamate factory) as raw material, and the raw material treatment is carried out first, and the raw material treatment includes filtering to remove impurities. , carry out sterilization treatment, sterilization treatment is under normal pressure, carry out high-temperature sterilization at 90°C for 15-20 minutes, so that the protein content reaches 60%, and the treated raw material is at 40-45°C, and the enzymatic activity is 118u Pepsin solution per mg, the amount added is 5-10% of the volume, the pH value is adjusted to 5-7, and the enzymolysis reaction is carried out for 8-12 hours. Bacteria can inhibit enzyme activity, and then conc...

Abstract

The invention relates to a preparation method of feed additive animal growth promoting peptide. According to the invention, rice protein is taken as raw material, treatment is carried to the raw material firstly, the treated raw material is added into a pepsin solution with enzyme activity being 118 [mu] / mg under 40-45 DEG C, the added amount of the treated raw material is 5-10 percent of volume, the pH value is regulated to 5-7, an enzymatic hydrolysis reaction is conducted for 8-12 hour s, after the enzymatic hydrolysis reaction, the temperature is increased above 90 DEG C, the temperature is kept for 15-20 minutes for sterilization to inhibit enzymatic activity, and the obtained product is concentrated and dried to obtain peptides with small molecular weight having average peptide chain length being 3.3. The raw material treatment comprises the following steps: after filtering to remove impurity, disinfection processing is carried out under normal pressure, high-temperature disinfection is carried out for 15-20 minutes at the temperature of 90 DEG C, and the protein content can reach 60%. The invention has the advantages that the product cost is low, the feed mixture can be fully absorbed by animals, the growth promotion function is obvious, the economic benefit of culturists is high, the application prospect is wide, no side effect is caused, no residue exists and the safety production requirement of animal products is satisfied.

Description

technical field [0001] The invention belongs to the field of small molecular weight peptides, in particular to a method for preparing feed additive animal growth-promoting peptides. Background technique [0002] Domestic research mainly focuses on the applied basic research on the nutritional metabolism, physiological function and corresponding product development of small peptides, and the application scope is concentrated in the fields of medical care products and cosmetics. In terms of feed additives, because the cost has not been reduced to a level that is acceptable to farmers and can compete with other additives, the application of small peptides to the field of feed additives and large-scale commercial production is still being explored. . [0003] The shortage of protein resources and environmental pollution are two major problems in the aquaculture industry in our country. In particular, there are still problems of unreasonable use and low conversion rate in the u...
