Background
The gamma-aminobutyric acid is an important inhibitory neurotransmitter in a human body, and has the physiological effects of activating brain nerve cells, delaying memory decline and dementia, stabilizing blood pressure, improving immunity, relieving anxiety and the like. However, in the existing food, the content of gamma aminobutyric acid is generally low, and the daily requirement of the public, particularly the middle-aged and the elderly cannot be met. Rice and rice products are important staple food for Asians, wherein the content of gamma aminobutyric acid in the brown rice is particularly high, but the national standard for high-quality rice processing is adopted. So that the brown rice is difficult to enter the high-quality rice market. Due to the limiting factor and the combination of the process advantages of the steamed rice, the invention develops the high-quality functional steamed rice rich in gamma aminobutyric acid. According to the invention, sodium chloride with certain concentration is added in the soaking stage to create abiotic adverse environmental stress induction so as to promote the conversion of the gamma aminobutyric acid and further promote the content of the gamma aminobutyric acid. The steamed rice prepared by the process is rich in gamma aminobutyric acid, vitamin B1, vitamin B2, various minerals and the like, and has the functions of activating brain nerve cells, stabilizing blood pressure, improving immunity and the like.

Aiming at the special physiological activity of gamma aminobutyric acid and the functional characteristics that the steamed rice is rich in various nutrient elements, the invention provides a processing technology of the gamma aminobutyric acid-rich steamed rice, which improves the content of the gamma aminobutyric acid in the steamed rice by edible salt induction soaking, and produces and prepares high-quality rice more suitable for middle-aged and old people to eat.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
(1) removing impurities: removing impurities in the rice raw material, then screening by using a 40-mesh sieve, removing dust and shrivelled grains, and screening full-grain rice for later use;
(2) cleaning: soaking the screened rice in clear water for 10-15 min;
(3) soaking: soaking the rice in a tank filled with warm water of 30-55 ℃ for 3-5 hours; adding sodium chloride with a certain concentration in the soaking process to create an abiotic high-salt reverse environment, inducing biotransformation of rice during soaking by utilizing high-salt stress to improve the content of gamma aminobutyric acid in the rice, and washing and desalting after soaking;
(4) steaming for gelatinization: placing the treated paddy into a high-pressure cooking pot, and introducing 115-125 ℃ steam for steaming gelatinization for 10 minutes;
(5) and (3) high-temperature drying: drying the cooked rice for 1-2h by hot air at 55-60 ℃ to remove the surface moisture of the rice;
(6) tempering: stopping drying for 2-4 hours;
(7) and (3) drying at low temperature: drying the paddy by using hot air at 38-42 ℃ until the water content is 13-15%;
(8) and carrying out post-treatment processes including rice hulling, rice milling and packaging to obtain the finished product of the rice.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, an edible salt stress induction auxiliary soaking process is adopted, an abiotic salt stress induction environment is formed in a soaking stage, the biotransformation of gamma aminobutyric acid in the soaking stage in the processing process of the steamed rice is promoted, and meanwhile, a severe external environment is caused to microorganisms due to the formation of a high-salt concentration environment, so that the fermentation corruption phenomenon of the rice in the long-time soaking process is improved to a certain extent; and the salt water and the washing liquid can be recycled. In addition, as the steamed rice is subjected to the processes of soaking, stewing and drying, the toughness of the rice grains is good, the embryo remaining rate is high, the taste is chewy and the rice meets the national high-quality rice processing requirements. The functional steamed rice rich in gamma aminobutyric acid, which is processed by the method, has the physiological effects of activating brain nerve cells, delaying memory decline and dementia, stabilizing blood pressure, improving immunity, relieving anxiety and the like.
