Abstract

The invention provides a microalgae metal chelated peptide and a preparation method thereof. The method comprises the steps of carrying out enzymolysis on a raw material, namely microalgae protein, by adopting a complex of protamex and flavorzyme, separating to purify, and carrying out freeze drying, thereby obtaining the metal chelated peptide. The amino acid sequence of the peptide is vdearp. According to the microalgae metal chelated peptide and the preparation method thereof, amino acids and small peptides play a role in promoting zinc absorption, and the amino acids or metal complexes of the peptide, e.g. Fe and Zn, have higher biological utilization ratio than that of inorganic salts and are free from toxic and side effects, so that the microalgae metal chelated peptide and the preparation method thereof have a very important significance in the research and development of biological-state zinc-protein hydrolysate chelated zinc.

Description

technical field [0001] The invention relates to a metal (Ca, Fe, Zn) chelating peptide, more specifically relates to a microalgal metal chelating peptide and a preparation method thereof, belonging to the field of biotechnology. Background technique [0002] Bioactive peptides derived from microalgae proteins have extremely high nutritional value, food safety and physiological health functions, and play an important role in promoting the growth, development and disease prevention of the body. They can be used as functional foods or food additives or even Drugs are applied to people's daily life. [0003] Calcium deficiency is a global nutritional problem. Because our people mainly eat plant-based diets, the phenomenon of calcium deficiency is even more serious. Therefore, calcium supplementation has become an important topic in the study of dietary nutrition in our country. Traditional inorganic calcium salts, such as calcium carbonate, calcium phosphate, calcium chloride, ...
