Production process of calcium iron zinc and selenium nutrition enhanced germinant long-shaped rice coarse rice powder

The invention relates to a production process of calcium iron zinc and selenium nutrition enhanced germinant long-shaped rice coarse rice powder, which is characterized in that: high quality long-shaped rice coarse rice is selected to guarantee the germinant rate, the high quality long-shaped rice coarse rice is sent into a classificator to remove weak and broken particles and to remove foreign matters such as stone, dust and the like; the selected coarse rice is washed by flowing water containing 0.5% sodium hypochlorite for three times so as to remove surface microorganisms, and then the coarse rice is washed by pure water for five times; the washed coarse rice is immersed in immersion solution at the room temperature for 9 hours, every liter of coarse rice immersion liquid contains 2g of calcium chloride, 0.25g of green copperas, 0.2g of zinc sulfate and 0.25mg of sodium selenite, the immersion liquid is replaced twice during the period of 9 hours so as to prevent the pollution of the microorganisms; the coarse rice is moisturized at 30 DEG C to germinate for 20 hours; the coarse rice is washed with pure water for five times to prevent the pollution of the microorganisms during the period of 20 hours; the coarse rice is re-washed with pure water for three times after the germination is ended; and then the coarse rice is swelled, smashed, screened and packed. The rice powder can also provide necessary trace elements of the human body such as selenium, calcium, iron, zinc and the like on the premise of improving the nutrient substances such as gamma-propalanine and the like.
