Abstract: Collagen peptide metal chelates are formed by collagen peptides and metal ions through coordinate covalent bonding or adsorption binding. They have been considered as the potential approach to delivering metal mineral elements to consumers with many virtues, such as higher bioavailability, higher safety and higher bioactivity. Chelate mechanism, stability, absorption and utilization, functional activity and production technologies of collagen metal chelates were reviewed and the development prospect were also foreseen in this paper, which was expected to provide reference for related reasearches.

Key words: collagen peptide metal chelates, chelate mechanism, functional activity, production technologies
