Preparation method of amino acid chelate

Abstract

The present invention discloses a preparation method of an amino acid chelate. Soybean proteins are hydrolyzed, amino acids are extracted as a chelating ligand, and the mixed amino acid and metal ionminerals subjected to a chelating reaction in conditions of a stabilizer, and an appropriate pH value, temperature and solution isoelectric point to prepare the chelate. The preparation method is simple and good in chelation property. The prepared amino acid chelate is high in chelation rate, has better physiological activity than a compound formed by chelation of a traditional single amino acid,and can promote absorption and utilization of mineral metal ions by living organisms.

Description

technical field

[0001] The invention relates to a preparation method of an amino acid chelate, which belongs to the technical field of health product processing. Background technique

[0002] Amino acid chelate is a compound with a ring structure formed by the coordination reaction of one or more amino acid groups and metal ions. It has the advantages of good stability, high absorption rate, high biological potency, and low toxicity. It is widely used in all aspects of production and living, especially as a new type of nutritional supplement in medicine and health food, and has achieved good results.

[0003] At this stage, the preparation methods of amino acid chelates mainly include chemical synthesis and electrolysis-semipermeable membrane. The problems in these two methods are: slow reaction, long time, low chelation rate of the product, and removal of amino acid that does not participate in the synthesis. Remaining reactants are more difficult, therefore, large-scale p...
