Abstract: Emulsion gel, a complex colloid system in which emulsion and gel coexist, is widely used in pharmaceutical, cosmetic and food industries with a unique structure of three-dimensional network. As a high-molecular protein, soybean protein has good functional and physicochemical properties. Soybean protein emulsion gels is a core-shell structure prepared by heat induction, salt induction, phosphorylation modification, enzyme induction and other methods, which has excellent gelability and stability. Emulsion gel has been widely studied and applied as a fat substitute to reduce the content of animal protein and fat in the food system, and a new material for three-dimensional printing. In order to better understand the research progress of soybean protein emulsion gels, the classification and preparation methods of them were reviewed. The structure and formation mechanism of emulsion gels of soybean protein and polysaccharide were analyzed and summarized. The functional properties such as gelability, rheology and stability of soybean protein emulsion gels were expounded. Finally, the application of soybean protein emulsion gels was summarized to provide theoretical basis for the processing and utilization of emulsion gel products.
