The content of γ-aminobutyric acid obtained by this method is much higher, up to 131.62-215.76 mg, but this process takes 40-55 hours, it takes a long time, and other foreign substances are added, especially gibberellins should not be used during food processing. Adding it can not guarantee food safety; if it takes a long time, it is unknown whether other substances will be produced in the process, and the original taste and flavor of the rice will be destroyed.
[0006] CN 112314864A discloses a high GABA production method including eight steps of raw material preparation, impurity removal, preparation of nutrient solution, nutrient adjustment, cultivation, microgelatinization, drying, shelling, rice milling, and embryo extraction. The GABA content can reach 277-291mg / 100g, but neither sodium metavanadate nor naphthaleneacetic acid in the nutrient solution can be used in food processing, and there are potential safety hazards

Embodiment 1
[0044] Embodiment 1 is rich in the production method of the Wuchang rice of gamma-aminobutyric acid
[0045] 1. Production method
[0046] 1) Raw material screening: rice is used as raw material, the rice is new local grain in Wuchang, impurity is removed (impurity is less than 0.8), the germination rate is not less than 93%, the moisture content is 14.5-15%, and the test roughness rate is 78% Above, the polished rice rate is over 64%, reaching the national standard GB / T 19266;
[0047]2) Humidification: put the rice in the tank, and then humidify through 6 humidification sections in sequence, so that the relative humidity of the raw material reaches 94%, the temperature reaches 40°C, and the moisture content increases to 20%;
[0048] Among them, the six humidification sections include:
[0049] Humidification 1 section: air supply temperature 60°C, supply air humidity 94%, humidification for half an hour, moisture value reaches 15.3%, the system automatically enters humidi...

Abstract
The invention discloses a production method of Wuchang rice rich in gamma-aminobutyric acid. The production method comprises the following steps: screening unhulled rice, putting the original unhulled rice with the moisture content of 14.5-15% into a bin tank, and humidifying through a plurality of humidifying sections in sequence, so s to make the relative humidity of the raw material reach 85-95%, the temperature reach 20-50 DEG C and the moisture content increased to 19-20%, sequentially drying the raw material through a plurality of drying sections until the water content of the raw materials reaches 14-15%, cooling the raw material, and whitening the cooled raw materias to obtain the Wuchang rice rich in gamma-aminobutyric acid. According to the production method of the Wuchang rice rich in gamma-aminobutyric acid, unhulled rice is used as a raw material, humidification and temperature control measures are taken under physical conditions, and substances such as growth agents, mineral substances and vitamins are not added; and the Wuchang rice which has the same taste as common rice and is rich in gamma-aminobutyric acid is prepared through the processes of drying, whitening and the like, and the gamma-aminobutyric acid can reach 8-15 mg/100 g.
Description
technical field [0001] The invention relates to a production method of rice rich in γ-aminobutyric acid, which belongs to the field of grain processing. Background technique [0002] China is the world's largest rice producer, and its annual output has ranked first for many years in a row. Rice is the main ration of Asians and plays an important role in economic life. With the improvement of rice processing level, people mainly eat refined white rice and refined white flour. However, with the improvement of people's living standards and the change of consumption concept, consumers have changed from "eat enough" to "eat well" now, and pay more attention to the nutritional value and health function of products. [0003] γ-Aminobutyric acid, referred to as GABA, is an inhibitory neurotransmitter in the central nervous system of mammals, which reduces neuron activity and plays an important role in the cerebral cortex, hippocampus, basal ganglia, and cerebellum. The lack of it ...
