Abstract: Gelation is one of the main functional properties of protein. The gel formation of protein is affected by many physicochemical factors, and metal ion is one of the major factors affecting protein gelation behavior. The mechanism of the gel formation of protein is elaborated in this paper. Additionally, this article reviews the effects of metal ions on the microstructure, physicochemical characteristics, aggregation behavior, molecular conformation and main molecular forces of protein gels and the value of protein gelation for researchers is predicted in order to provide a theoretical guidance for further researches of the mechanism of action metal ions on protein gelation and the improvement of protein gel products.

Key words: metal ions, protein, gelation, aggregation, molecular conformation
