Problems solved by technology

[0004] Due to the inherent defects of pig blood protein itself, such as deep color, fishy smell, low digestibility and absorption rate of livestock and poultry, if it is directly used as animal protein, not only the palatability is poor, but also the conversion rate, digestibility and absorbability in animals are relatively low.

Abstract

The invention discloses a method for preparing a composite amino acid from pig blood. The method comprises the following steps: by taking decontaminated pig blood powder as a raw material, performinghydrolysis by using sulfuric acid, performing pressurized hydrolysis on the pig blood raw material twice, concentrating hydrolysates, further neutralizing the hydrolysates by using a NaOH solution soas to obtain a neutralization liquid, performing decoloring adsorption on the neutralization liquid twice by using activated carbon, and finally washing and drying the decolored liquid, so as to obtain a finished product of a pig blood composite amino acid. The pig blood composite amino acid is prepared by using a twice pressurized hydrolysis method creatively, so that the method has the advantages of being simple and convenient, high in yield, low in cost and good in practicability, and has great practical significances in solving the problems that amino acid varieties are in shortage in China and demands of medical departments cannot be met at present.

Description

technical field [0001] The invention relates to the technical fields of food and medicine, in particular to a technology for preparing compound amino acids with pig blood. Background technique [0002] my country's animal blood protein resources are very rich, and using these resources to produce amino acids and extract single amino acids or compound amino acids has become one of the important ways to develop the amino acid industry in my country. [0003] There are mainly several technical solutions for extracting amino acids from pig blood: The first solution is to hydrolyze the natural protein and extract various single L-type amino acids respectively through ion exchange chromatography. For this method, it is difficult to form an industrial production scale. This is because the industrial production of amino acids mainly uses fermentation, chemical synthesis, and enzymatic methods in countries with more advanced technologies in the world. The cost of separating and ext...
