Abstract

Peanut peptides are deep-processed products of peanut protein, known for their good stability, ability to be directly digested and absorbed by the small intestine, and enhancement of human immunity.Current research on peanut peptides mainly focuses on their antioxidant and antibacterial properties, but they also exhibit excellent metal ion chelation activity.Peanut peptide-metal ion chelates have garnered widespread attention as a new type of metal element supplement.In comparison with inorganic metal ion, peanut peptide-metal ion chelates are considered ideal metal element supplements due to their easier digestion and absorption by the gastrointestinal tract, higher bioavailability, and greater safety.This article reviews the preparation processes and separation-purification methods of peanut-metal ion chelating peptides, analyzes the factors affecting the chelating ability of peanut peptides, further summarizes the chelation mechanism of peanut peptide-metal ions, and also discusses the bioavailability of peanut peptide-metal ion chelates.This article aims to provide theoretical references for the preparation of peanut peptide-metal ion chelates and their application in functional foods and the development of new metal ion supplements.

Key words： peanut peptide; peptide mineral chelate; separation and purification; chelating mechanism; bioavailability
