Abstract
The objective of the present invention is to provide a high-purity rice-protein composition with improved tongue feel and a melt-in-the-mouth quality, and a method for manufacturing the composition. The rice-protein composition comprises glutelin and prolamine, the protein content with respect to the solid content being at least 90%. Rice protein extracted by an alkaline solution from rice or rice flour is neutralized and coagulated at a temperature no lower than 40 80 DEG C., or is coagulated by adding a divalent metal ion and then neutralized, or glucono-delta-lactone is added and the solution is heated to gel the protein; by therein keeping the pH of the rice-protein composition no lower than 7.0 or no higher than 4.0, a rice-protein composition with extremely good dispersibility and tongue feel can be obtained. Further, by heating to at least 80 DEG C. after adjusting pH, a composition with high water absorbency is achieved.
