Benefits of technology

This patented technique uses specific chemicals called proteolases that break down or altered rice's albumin molecules making them easier to dissolve when mixed with other materials like milk powder during processing. These techniques help improve the efficiency at producing high-quality breaking wheat products while reducing costs associated therewith.

Problems solved by technology

The technical problem addressed by this patented method relates to improving the efficiency at producing valuable protease containing products like peptides or amino acids (peptide) that can be used as ingredients in various applications including healthcare nutritional supplementation and cosmetic industries due to their unique properties compared with traditional methods involving breaking down rice into smaller parts called floury seeds.

Abstract

The invention discloses broken rice deep processing technology, and particularly relates to processing technology for extracting protein by a broken rice enzyme method. Broken rice is subject to superfine grinding, and added with water and sodium bicarbonate; the mixture is blended and carries out an enzymolysis reaction; solid-liquid separation is performed to prepare rice starch and rice protein. The protease preparations used in the enzymolysis reaction are amylase and cellulase, and the enzyme activities of the two are 30 U/g and 10 U/g respectively. The processing technology for extracting protein by a broken rice enzyme method of the invention performs degradation and modification of rice protein by using the protease preparations, and converts the rice protein into soluble peptide which is then extracted. The extraction reaction condition is mild; the protein polypeptide chain can be hydrolyzed into short peptide chains, which both increases the protein dissolvability and the solid content in the extract, and reduces energy consumption for removing water in the extract. Meanwhile, the protein recovery rate is up to 85%; the broken rice total utilization rate is up to more than 55%; full utilization of the broken rice resources is realized; and important effect on the integration of national grain resources is provided.
