Abstract

The invention belongs to the field of rice deep processing technologies and in particular relates to a method for co-producing the high-purity rice starch and rice protein. The method is characterized in that washing rice used as a raw material, soaking, grinding to obtain thick liquid, separating, adjusting the pH of liquid supernatant, performing enzymolysis, washing, performing settlement separation, and then drying to obtain the high-purity rice protein; or obtained precipitate is subjected to alkaline protease purification, pH adjustment, ethanol purification, washing, settlement separation, drying to obtain a high-purity rice starch product. The method can be used for co-producing the rice starch and rice protein, and can effectively improve the purity and increase the yield of the product. The product obtained by using the method can be used as the raw material for deep processing of food.

Description

technical field

[0001] The invention belongs to the technical fields of rice deep processing technology and starch and vegetable protein processing, and in particular relates to a method for co-producing high-purity rice starch and rice protein. Background technique

[0002] China is a big rice producing country. In 2012, China's annual rice output reached 107.7 million tons. Compared with advanced developed countries, China's rice deep processing is relatively late, and the product is relatively single. Starch and protein are the two main components of rice in deep-processing products of rice. Extracting and separating rice starch and rice protein from rice is beneficial to deep processing and comprehensive utilization of rice.

[0003] Rice starch is an important grain starch. Among all known grains, rice starch has the smallest particle size and the largest unit surface area. It can absorb more flavor substances and has a smooth and delicate taste. Rice starch is white in...
