Embodiment 1

[0033] Prepare a selenium-enriched nutrient solution, which includes sodium selenite, amino acid peptides, potassium dihydrogen phosphate and fulvic acid.

[0034] During the booting-full heading stage of the rice growth period, the rice is sprayed with a selenium-enriched nutrient solution with an ultra-micro sprayer, and the amount of selenium sprayed is controlled at 500-2000 mg / mu. In this example, since the self-prepared selenium-enriched nutrient solution is sprayed during the growth period of rice, through the biotransformation process, after the rice matures, it is rich in organic selenium that is beneficial to the human body. Spraying selenium-containing water can easily cause the selenium content to exceed the standard.

[0035] After the rice is mature, the harvested selenium-enriched rice is selected to remove impurities, and the shell is removed by a soft roll to obtain germ rice with germination vitality.

[0036] Wash 300g of germ rice with clear water to remov...

Embodiment 2

[0043] Prepare a selenium-enriched nutrient solution, which includes sodium selenate, amino acid peptides, potassium dihydrogen phosphate and fulvic acid.

[0044]During the booting-full heading stage of the rice growth period, the rice is sprayed with a selenium-enriched nutrient solution with an ultra-micro sprayer, and the amount of selenium sprayed is controlled at 500-2000 mg / mu.

[0045] The harvested selenium-enriched rice is selected to remove impurities, and the shell is removed by soft rolls to obtain germ rice with germination vitality.

[0046] Wash the germ rice with clean water to remove dust and bran powder, sterilize the selected germ rice with ozone water, and wash the germ rice after disinfection with clean water;

[0047] Soak 300g of germ rice in water with a water temperature of 40°C and a pH value of about 7.5. When the water absorption rate of the germ rice reaches 8%, wash it with water, then continue soaking and use sodium bicarbonate and white vinegar...

Embodiment 3

[0053] The harvested selenium-enriched rice is selected to remove impurities, and the shell is removed by soft rolls to obtain germ rice with germination vitality.

[0054] Wash 500g of germ rice with clear water to remove dust and bran powder, sterilize the selected germ rice with ozone water, and wash the germ rice after disinfection with clear water;

[0055] Soak the germ rice in water with a water temperature of 30°C and a pH value of about 7.0. When the water absorption rate of the germ rice reaches 5%, wash it with water, then continue soaking and use sodium bicarbonate and white vinegar as regulators to adjust the pH value of the soaking solution to 5.0 , the whole soaking process is controlled within 24 hours, wash and drain after soaking;

[0056] In a light-proof environment, the germ rice after draining is germinated and cultivated, the germination temperature is controlled at 31° C., the relative air humidity is 70%, and the cultivation time is 24 hours;

Abstract

The invention provides a preparation method of high-content gamma-aminobutyric acid selenium-rich germinated brown rice. The preparation method comprises the following steps of: spraying a selenium-rich nutrient solution to rice in the booting-full heading stage of rice growing period; shelling selenium-rich rice to obtain milled rice with embryo, wherein the milled rice with embryo has germinating vigour; disinfecting and soaking for 6-36 hours in hot water being 5-40 DEG C, and controlling the pH value of the soak solution by utilizing sodium bicarbonate and white vinegar as regulators; cultivating the milled rice with embryo for 10-36 hours under the conditions that temperature is 25-34 DEG C and relative air humidity is 50-90%; treating with water being 70-75 DEG C when length of sprout is 0.5-1mm, draining, and carrying out low temperature drying at the temperature of less than 50 DEG C. The method for preparing the high-content gamma-aminobutyric acid selenium-rich germinated brown rice provided by the invention is stable and reliable in process and is beneficial to enrichment and maintaining of gamma-aminobutyric acid.

Description

technical field [0001] The invention relates to a rice preparation and deep processing technology. Background technique [0002] Selenium, as an essential trace element for the human body, is an active component of glutathione peroxidase. Research results in recent years have shown that selenium mainly has the following physiological functions: [0003] 1. Selenium has a strong antioxidant capacity. Its effect is similar to that of vitamin E, but it is more effective. It can regulate the speed of redox reactions in the body, affect the metabolism and activity of some important enzymes, and regulate vitamins A, C, E, K absorbs and consumes in the body, participates in the synthesis of coenzymes A and Q, improves the body's immunity, and resists aging. [0004] 2. It has a strong antagonistic effect on certain carcinogens, and can inhibit the decomposition of chemical carcinogens [0005] Carcinogens, such as aflatoxin, tetraethyl lead, etc., can also excrete harmful metal ...
