Problems solved by technology

In the current research on rice starch and protein, different methods are used to destroy one of the components to release the other component. There is no report on the co-production of rice starch and protein, such as the production of starch sugar by double enzyme method , to obtain rice protein by enzymatically hydrolyzing starch into sugar, but due to the influence of high protein and fat in the liquefaction process, the quality of the obtained syrup is far from that of cornstarch syrup, and it is generally only used in low-end products. or obtain rice starch by e

Abstract

The invention relates to a method for coproduction of rice starch and rice protein. The method comprises the step of pretreatment of raw materials, first mixing and enzyme reaction, first separation and washing, homogenization, second separation and washing, second mixing and enzyme reaction, third separation and washing, drying and the like. The method disclosed by the invention is used for realizing the coproduction of the rice starch and the rice protein. In the rice starch produced by the method disclosed by the invention, the content of protein is below 0.3%, the content of starch is above 96%, the dextrinization rate of the starch is below 2.5%, the extraction rate is above 90%, the degree of hydrolysis of the rice protein is below 10%, the content of the protein is above 90% and the extraction rate of the rice protein is above 85%. The rice starch produced by the method disclosed by the invention can be widely applied to the industries such as foods, medicines and cosmetics, while the rice protein can be widely applied to the fields of health foods, nutritious foods and the like, and the additional value of deep processing of rice is increased greatly.

Description

【Technical field】 [0001] The invention belongs to the technical field of rice deep processing. More specifically, the invention relates to a method for co-producing rice starch and rice protein, and also relates to the rice starch and rice protein obtained by the method. 【Background technique】 [0002] The two most important ingredients in rice are rice starch and rice protein, with a dry basis content of about 85% and 7% respectively. Among all commercial starches, rice starch has the smallest granules, with a particle size of about 3 μm to 8 μm. Most of its shapes are irregular polygons with sharp edges and corners. These characteristics determine its wide application in food, medicine, cosmetics, textiles and other industries. The application prospect of rice protein is a kind of high-nutrition, hypoallergenic grain protein, which is very suitable for special groups such as infants, the elderly and patients as application supplements, and is also an ideal source of high-...
