Problems solved by technology

In brown rice processing, the brown rice rate of indica rice is difficult to exceed 79.0%, and some broken brown rice and germless rice will inevitably be produced. If automatic de-broken and germless brown rice is not used, these rice will inevitably be fermented, mildewed, or even damaged within 72 hours. Produce aflatoxin, which may make germinated rice unsafe
And adopting the process of removing broken and germless brown rice significantly increases the product cost

Abstract

The invention discloses gamma-aminobutyric acid rich germinated brown rice and a method for preparing the same. The germinated brown rice is prepared by a step that a raw material of brown rice is soaked in a solution of calcium gluconate and then is cultured in a biochemical incubator, dried and hulled. The method can achieve a yield of brown rice of between 79 and 83 percent, prevent the brown rice from fermentation, mouldness and production of flavacin and ensure food safety, and is simple and low in production cost.

Description

technical field [0001] The invention relates to brown rice and a processing method thereof, in particular to a germinated indica brown rice rich in gamma-aminobutyric acid and a preparation method thereof. Background technique [0002] Studies have found that γ-aminobutyric acid is an active amino acid that plays an important role in the energy metabolism process of the human brain. It has the functions of activating glucose metabolism in the brain, promoting the synthesis of acetylcholine, lowering blood ammonia, anticonvulsant, lowering blood pressure, improving brain function and spirit. Various physiological functions such as stability and promotion of growth hormone secretion; germinated rice is rich in γ-aminobutyric acid. [0003] Among the three major grain varieties such as rice, wheat, and corn in my country, the output of rice ranks first, and 60% of the population in the country takes rice as a staple food. As the largest agricultural product processing industry...
