Abstract

The invention provides a production method of high-GABA (gamma-aminobutyric acid) rice. The method comprises the following eight steps: preparing materials, removing impurities, preparing a nutrient solution, regulating nutrition, culturing, carrying out micro-gelatinization, drying, shelling, milling rice and extracting embryos, wherein the step of preparing materials comprises preparing rice andthe nutrient solution, and the step of removing impurities comprises three impurity removal processes on the rice surface. When the nutrient solution is prepared, a clean vessel is taken, water, vitamin B1, vitamin B2, xylanase and glutamate decarboxylase are sequentially poured into the vessel, and a stirring rod is held by hand to stir for 5-10 minutes at the speed of 30 circles per minute. Byadopting the method disclosed by the invention, four series of nutritional rice including nutritional brown rice, high-precision nutritional rice, germ rice and nutritional rice germ can be obtained,the color, luster and taste of the finished rice are optimized and improved to a great extent, and the appetite of an eater can be better promoted. The rice of the invention is rich in nutritional ingredients such as GABA, dietary fibers, inositol, vitamins, minerals and anthocyanin (colored rice), and is more beneficial to the health of people when being eaten.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of high GABA rice. Background technique [0002] γ-aminobutyric acid is a naturally occurring functional amino acid and an important inhibitory neurotransmitter. It exists in a small amount in the brain and bone marrow of mammals; in addition, it is contained in vegetables and fruits A certain amount of gamma-aminobutyric acid, but the content is very small. As one of the important inhibitory neurotransmitters in the animal brain, γ-aminobutyric acid plays a very important neuroregulatory role in the life activities of animals. Its physiological functions mainly include the following aspects: (1) blood pressure lowering function , (2) Anti-arrhythmic effect, (3) Neurotrophic effect, (4) Regulate hormone secretion, (5) Prevent skin aging, brain aging, promote ethanol metabolism and improve sleep, treat uremia and CO poisoning, etc. . [0003] γ-amino...
