Abstract

The invention relates to the technical field of food processing, and discloses a production method of brown rice rich in γ-aminobutyric acid, comprising the following steps: placing the brown rice on perlite containing water, germinating under constant temperature and humidity conditions, and waiting for the buds to grow to 0.5- When 1mm, stop germination, dry, obtain described brown rice rich in γ-aminobutyric acid. In the present invention, the perlite has high water-holding capacity and permeability, and it can control brown rice to slowly absorb water, so that it stays in the imbibition stage, promotes enzyme activation, and makes it in a state of preparation for germination, but prevents The radicle protrudes, which suppresses the occurrence of bursting brown rice to the greatest extent, and improves the quality of germinated brown rice. At the same time, the introduction of hydrous perlite can also promote the germination of brown rice and increase the germination rate of brown rice.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of germinated brown rice rich in gamma-aminobutyric acid. Background technique [0002] Brown rice is the product of paddy husking. It is the whole grain that remains except for the outer shell. It consists of pericarp, seed coat, aleurone layer, embryo and endosperm. Compared with polished white rice, brown rice is richer in nutrients such as gamma-aminobutyric acid, a naturally occurring non-protein amino acid that is an important inhibitory inhibitor in the mammalian central nervous system. Neurotransmitter is the most important neurotransmitter in brain tissue. In addition, it also has the functions of lowering blood pressure, improving cerebral blood flow, regulating hormone secretion, nourishing nerves, anti-anxiety, anti-fainting, anti-arrhythmia, and anti-aging. Germinated brown rice is obtained by activating relevant biological enzymes inside...
