Abstract

The invention relates to a method for producing small peptide amino acid microelement chelate by way of the acid hydrolysis of protein. Animal protein or vegetable protein is adopted as raw material, and is hydrolyzed by hydrochloric acid. Hydrolysate is subjected to rough filtration and microfiltration, filtrate is deacidified by a nanofiltration membrane separation system, and the deacidified liquor is purified by way of ultrafiltration separation. Obtained small peptide and amino acid, the molecular weight of which is less than 1000 Dalton, are chelated with microelements, so that the small peptide amino acid microelement chelate is produced. The method is suitable for industrial production, the production cycle is short, the product yield is high, the three wastes cannot be produced in the process of production, and the product has good chemical stability, is rich in nutrition, can be easily digested and absorbed, can resist interference, is nonirritant, has the effect of improving the immunity of body, and is an ideal food nutrition enhancer and feed additive. The invention has a positive and profound significance on promoting the development of feed industry and breeding industry, enhancing the safety of poultry, livestock and aquatic products and protecting the health of human being.

Description

technical field [0001] The invention belongs to the protein processing technology and relates to the technical field of membrane separation. Background technique [0002] The protein hydrolyzate is peptone, peptide, etc., and the final product is amino acid. Peptides are linear polymers of amino acids. Usually, the linear peptide formed by 2 to 12 amino acid residues is called oligopeptide, also known as small peptide, short peptide, micropeptide, and those with more than 12 but not more than 20 amino acid residues are called oligopeptides. Those containing more than 20 amino acid residues are called polypeptides. Modern scientific research has found that most of the end products of protein digestion in the digestive tract are small peptides rather than free amino acids. Small peptides can enter the systemic circulation through intestinal mucosal cells and directly participate in the synthesis of tissue proteins. Some small peptides with special physiological activities ...
