Embodiment 1
[0017] Embodiment 1: The harvested red rice paddy is dried and processed into brown red rice, that is, the red rice with undamaged germ. Get 100 kilograms of unpolished red rice and soak in 200 liters of sodium selenite concentration and be 120 mg / liter of selenium solution, pick up after keeping 20 hours in the room of temperature control at 30 degrees Celsius. Drain the water until the red rice grains are dry and immerse them in the selenium solution again, keep them in a room with a temperature controlled at 30 degrees Celsius for 14 hours, then pick them up, and spread them into a thin layer with a thickness of 5 cm. Drench the same room with a selenium solution with a concentration of 120 mg / L every 3 hours. After 14 hours, the red rice grains have germinated to 2-3 mm, and then rinse the red rice with clean water to wash away the selenium solution still attached to the surface of the red rice. The obtained red rice is air-dried to a water content of 14% and a selenium c...
Embodiment 2
[0018] Embodiment 2: The harvested red rice paddy is dried and processed into brown red rice, that is, the red rice with undamaged germ. Get 100 kilograms of unpolished red rice and soak in 200 liters of sodium selenite concentration and be 190 mg / liter of selenium solution, keep 26 hours in the room of temperature control at 29 degrees Celsius and pick up after. Drain until the red rice grains are wet and dry, then immerse in the selenium solution again, keep it in a room with a temperature controlled at 29 degrees Celsius for 12 hours, then pick it up, and spread it into a thin layer with a thickness of 2 cm. Drench with a selenium solution with a concentration of 190 mg / L every 2 hours in the same room. After 12 hours, the red rice grains have germinated to 3-5 mm, and then rinse the red rice with clean water to wash away the selenium solution still attached to the surface of the red rice. The obtained red rice is air-dried to a water content of 12% and a selenium content ...
Embodiment 3
[0019] Embodiment 3: The harvested red rice paddy is dried and processed into brown red rice, that is, the red rice with undamaged germ. Get 100 kilograms of unpolished red rice and soak it in 200 liters of sodium selenite concentration and be 150 mg / liter of selenium solution, keep it in a room with a temperature of 28 degrees Celsius for 24 hours and then pick it up. Drain until the red rice grains are wet and dry, then immerse in the selenium solution again, keep it in a room with a temperature controlled at 28 degrees Celsius for 12 hours, then pick it up, and spread it into a thin layer of 3 cm thick. Drench the same room with a selenium solution with a concentration of 150 mg / L every 3 hours. After 10 hours, the red rice grains have germinated to 1-2 mm, and then rinse the red rice with clean water to wash away the selenium solution still attached to the surface of the red rice. The obtained red rice is air-dried to a water content of 13% and a selenium content of 25.4 ...
