Problems solved by technology

In the prior art, in order to prevent the breeding of microorganisms in the germination process of highland barley rice, sodium hypochlorite soaking method is used to sterilize it. Although this method can effectively prevent microorganisms from multiplying, it needs a large amount of water to rinse after sodium hypochlorite disinfection, which will cause protein, cellulose, etc. The loss of substances reduces the content of nutrients in germinated rice

Abstract

The invention belongs to the technical field of food processing, and specifically relates to highland barley germinated rice with high gamma-aminobutyric acid content, and a processing method and an application thereof. The processing method comprises the following steps: removing dust from highland barley rice so as to obtain clean highland barley rice; placing the clean highland barley rice in ahigh-temperature environment of 55-70 DEG C for 6-12 h so as to obtain sterilized highland barley rice; soaking the sterilized highland barley rice in warm water containing a bacteriostatic agent at40-50 DEG C for 8-10 h, wherein the bacteriostatic agent is an iron salt solution; performing germination treatment on the soaked highland barley rice by adopting a constant-temperature and constant-humidity incubator or a germination device until germination is finished; and drying the germinated highland barley rice so as to obtain the highland barley germinated rice. With the method provided bythe invention, infectious microbe infections like mildew and rancidity are avoided in the highland barley germination process; loss of nutrient substances is reduced; highland barley germination is neat; the germination rate is 97% or above; meanwhile, the gamma-aminobutyric acid content of the prepared highland barley germinated rice reaches 69.26 mg / 100 g or above.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to germinated barley rice with high gamma-aminobutyric acid content, a processing method and application thereof. Background technique [0002] Highland barley is an important cereal crop rich in dietary fiber, high in protein and low in fat. The average protein content of highland barley is about 8-14%, containing 18 kinds of amino acids, including 8 kinds of amino acids necessary for adults. Highland barley rice is also rich in various vitamins. Every 100g of highland barley rice flour contains about 0.3mg of vitamin B1, about 0.2mg of vitamin B2, and about 0.3mg of vitamin E. The average crude fat content in highland barley is 1-3%, which is lower than that of corn, oats, sorghum and buckwheat. [0003] Gamma-aminobutyric acid (GABA) functions as a molecular signal as an inhibitory neurotransmitter. GABA not only has the effect of reducing neuronal activity...
