GABA is a chemical compound, abbreviated as GABA, as an amino acid that is widely found in vertebrates, plants, and microorganisms.
GABA is an important central nervous system inhibitory neurotransmitter that belongs to:The substances naturally secreted by the human body can inhibit the central nervous system, which is overactive due to excitement and anxiety, and help the body and brain relax and settle down.
With the deepening of research, the physiological function of GABA has been continuously elucidated, and has developed into a new functional factor, which is widely used in medicine, food and health care, agriculture and other industries.
At present, the food safety of GABA has been widely recognized by countries including the United States and Japan, and the regulations of various countries have successively allowed GABA to be added to ordinary foods. In 2009, the Ministry of Health approved -aminobutyric acid as a new resource food in accordance with the provisions of the Food Safety Law of the People's Republic of China and the Measures for the Administration of New Resource Food.
- Diet of aminobutyric acid (GABA)**
GABA is widely available in foods** and tends to be found higher in plant-based foods than in animal-based foods, and higher in fruits and vegetables than grains. In addition,GABA content is also significantly affected by plant substrate, location, stage of development and postharvest processing conditions, for example, cereals have higher levels of GABA in bran and germ than in endosperm；Processing methods such as freezing, sprouting, anaerobic conditions, and ultrasound can increase the amount of GABA in food.
The enrichment of GABA in plants is related to the stress response of plants, and proteins are hydrolyzed by their intrinsic proteases to produce a large amount of glutamate, which can be catalyzed by glutamate decarboxylase to produce GABA under certain conditions.

Formation of aminobutyric acid (GABA) in parboiled rice
The germ of rice can be enriched with -aminobutyric acid through the natural fermentation process, the principle is to give certain conditions to the dormant rice humidity, temperature and light after the germination begins to germinate, the rice contains glutamate, through the germination of glutamate carboxylase action, the generation of -aminobutyric acid.
- aminobutyric acid in parboiled riceThe paddy enters the HPT patented equipment system, and the PLC program control system is applied to realize automatic control. Its working principle is that the rice is soaked for 4-6 hours, the water temperature is kept at about 50, and the germination is activated in the soaking tank (the condition of germination is to maintain a certain temperature and humidity), so that the glutamate accumulated in the germ of rice is decarboxylated to generate a large amount of -aminobutyric acid, which gradually diffuses with the water and concentration gradient and moves to the endosperm part.
After the germinated rice is processed by a series of hydrothermal processes such as steaming, drying, and slow cooling, it is then shelled and milled by a special parboiled rice production line to obtain high-nutrient parboiled rice rich in aminobutyric acid.
- Analysis of the effects of aminobutyric acid (GABA).
Improves sleep
Because -aminobutyric acid has the effect of inhibiting the nerve center, it has the effect of sleeping and sedating, and it is a neurotransmitter without drug dependence and ***.
Lowers blood pressure
GABA can act on the vascular motor center of the spinal cord, promote vasodilation, and achieve the effect of lowering blood pressure by regulating the central nervous system. Patients with hypertension tend to have reduced renal function, and GABA has a renal function activation effect. Due to the activation of the diuretic effect, excess salt can be excreted from the urine, which lowers blood pressure.
Relieves anxiety
GABA is an inhibitory transmitter of the central nervous system, its role is to reduce neuronal activity, prevent nerve cells from overheating, -GABA can bind to anti-anxiety brain receptors and activate them, and then synergize with other substances to prevent anxiety-related information from reaching the brain instruction center.
Improves brain function
GABA can enhance the activity of glucose polymethacrylase, make the brain neurologically active, promote the basal metabolism of brain tissue and repair brain nerves, improve nerve function, increase the activity of brain cells, improve brain function, and improve memory.
Strengthen the liver and kidneys
GABA also has a certain effect on improving the function of the liver and kidneys, -GABA can inhibit the decarboxylation reaction of phosphoric acid and reduce blood ammonia. A large amount of phosphoric acid is fused with ammonia and converted into urea solution and excreted out of the body to eliminate ammonia toxicity and improve liver function.
Beauty and skin care
In the latest research, -aminobutyric acid also has the effect of preventing ** aging, improving lipid metabolism, and preventing arterial aging.
Promotes growth in height
GABA is an important inhibitory neurotransmitter that promotes the release of growth hormone from the pituitary gland and can promote the growth of children with short stature due to abnormal pituitary gland function and abnormal growth hormone secretion.
In the "Dietary Nutrient Reference Intake for Chinese Residents" compiled by the Chinese Nutrition Society, the daily intake is 264mg GABA can improve 65% of insomnia and depression symptomsIntake of 28mgaba can play a role in psychological stress reduction;Intake of 100mg of GABA has the effect of relaxing mood and reducing anxiety.
With the increase of age and the aging of physical functions, the production and secretion of GABA will gradually decrease, and the amount of GABA in the human body will decrease by about 5% every 10 years, resulting in poor sleep, anxiety, unstable blood pressure, memory impairment and other problems.
GABA is indispensable for human health, as well as for efficient Xi, work and life. However, research shows:GABA, which is lacking in the human body, is difficult to synthesize on its own and can only be replenished by consuming foods and nutrients that contain GABA.
In the food structure, staple foods occupy an important position, and the staple foods of three meals a day are replacedRich in -aminobutyric acid (gabaparboiled rice, by adjusting the diet and eating normally, you can replenish it.
