Rice protein mainly by the qing protein, globulin, alcohol-soluble protein and protein in the valley of four proteins, rice is mainly studied the protein, by albumin (4% ~ 9%), salt soluble globulin (10% ~ 11%), alcohol-soluble valley protein (3%) and the valley of alkali soluble protein (66% ~ 78%) composition. In the grain protein, born of rice protein price (B.V.) and protein price (P.V.) are better than other high protein. Rice protein amino acid composition balance is reasonable, and the amino acid content, high is other plant protein could comprehend. Rice protein is recognized as the quality of the food protein, WHO/FAO with the ideal mode recommended. The life of rice protein prices high, its high nutritional value, and eggs, milk and beef comparable. In addition, rice protein is resistance prototype protein, won’t produce allergic reaction, to production babies and infants food is extremely advantageous. Rice protein not only has the unique nutrition function, there are some other health care function. A recent study suggests, rice protein can reduce serum cholesterol.
Rice, rice worse, rice bran, etc can be used to raw material preparation rice protein, centering on the development and utilization of rice protein, researchers put forward different preparation methods, basically have: solvent extraction, enzymatic method, alkali distillation, acid extraction, physical extraction method and composite extraction.
