Abstract

The invention discloses a germinating nutrient solution and a method for producing germinated brown rice rich in gamma-aminobutyric acid by means of the germinating nutrient solution. According to the germinating nutrient solution, water serves as a solvent, each liter of water contains 0.5-1.0 g of sodium glutamate, 0.02-0.10 g of rice protein, 1-2 g of an alkaline protease preparation and 0.01-0.02 g of gibberellin. According to the method, germinated brown rice is soaked in the nutrient solution, germinates and then is dried, and the germinated brown rice rich in gamma-aminobutyric acid is obtained. The germinating nutrient solution is low in cost, easy to prepare, safe, efficient and high in gamma-aminobutyric acid conversion rate, each 100 grams of germinated brown rice contains 131.62-215.76 mg of gamma-aminobutyric acid, and the content of gamma-aminobutyric acid can be 22.1 times that of gamma-aminobutyric acid before germination. The method is simple in technology, large in yield and suitable for industrial production, and the germination rate can reach up to 85%; the obtained germinated brown rice is good in taste and high in nutritional value and has broad market prospects.

Description

technical field [0001] The invention relates to a germinating nutrient solution and a method for producing germinated brown rice with it, in particular to a germinating nutrient solution and a method for producing germinated brown rice rich in gamma-aminobutyric acid. Background technique [0002] China is the largest rice consumer in the world, and its rice production, consumption and inventory rank first in the world. Brown rice is the caryopsis after removing the outer protective cortex of rice. About 64% of the nutrients in brown rice are accumulated in the bran layer and germ, which only account for 10% of the weight of brown rice. Direct processing of brown rice can make full use of food resources. Research and development of new brown rice food can improve the effective utilization rate of my country's grain resources, and is an effective way to save grain resources. [0003] γ-aminobutyric acid is a natural non-protein amino acid that widely exists in nature and is ...
