Abstract: Rice protein,which has high nutritional value is easily digested and absorbed. And due to its hydrolyzed peptide can function as lowering blood pressure and cholesterol,it has broad development value and application prospects. Therefore,this paper elaborates the separation and extraction techniques like alkaline extraction and acid precipitation and enzymatic methods,structural characteristics like spatial composition,like function properties foaming and emulsifying,and the current status of application of rice protein. It is hoped to provide a reference for the development and utilization of rice protein and related in-depth product processing research,and to improve the economic benefits of rice resources in China.
