calcium chelated peptide, isolation and purification, chelated ability, stability, bioavailability, Food processing and manufacture, TP368-456

Calcium is an essential nutrient and plays an important role in life and health. Insufficient calcium intake in the body can lead to kinds of diseases, such as rickets and osteoporosis. As more and more calcium chelated peptides are prepared from food in recent years, the advantages of calcium chelated peptides like good stability and high bioavailability have attracted much attention and calcium chelated peptides have been reported to be a kind of ideal calcium supplements. In this paper, the research progress of calcium chelted peptide is summarized, the preparation, separation and purification methods of calcium chelted peptide are introduced, the factors affecting its chelating ability are analyzed, and the ways to promote the bioavailability of calcium are also discussed, in order to provide help for the development and utilization of calcium chelted peptide in functional foods in the future.
