METHOD FOR PRODUCING RICE PROTEIN, RICE PROTEIN PRODUCED BY THE METHOD, AND FOOD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing rice protein comprising fractionating rice protein under safe condition without using any chemicals or medicaments undesirable for intake into human bodies.;SOLUTION: The method for producing rice protein comprises: treating rice, rice powder and/or rice bran with dilute acid such as lactic acid; subjecting the treated material to centrifugal separation to collect extract liquid; and salting out the extract liquid with common salt or the like to fractionate glutelin. Optionally, the method comprises: adding reaction-system enzyme liquid to rice, rice powder and/or rice bran; subjecting the obtained reaction liquid to centrifugal separation to collect precipitate; precipitating starch by a sucrose gradient centrifugal separation method to eliminate the starch; subjecting the obtained solution to pepsin digestion; subjecting the digestive fluid to centrifugal separation to collect precipitate; and dialyzing the precipitate to fractionate prolamin. The thus obtained rice protein is used as food, as it is, or used as part of food, or drying and pulverizing the rice protein to be utilized as food material.;COPYRIGHT: (C)2007,JPO&INPIT
