In fact, the most important central part of rice is the germ. As the name implies, the so-called "bud" is the part that breeds new life. Its scientific name should be "rice with embryo retention", that is, rice with embryo retention rate above 80%. The germ retention rate reached 80%. Germ rice is produced by grinding rice with germ rice machine. The embryo retention rate of different germ rice machines is different, generally around 60%-70%. Inferior germ rice machine grinds little or no germ.
If the germ of rice is well preserved, it is necessary for aleurone layer to keep it together and fresh. Therefore, the germ should be preserved in aleurone layer. Of course, it is to ensure that the hygiene level reaches the standard that cannot be washed, so as to avoid the loss of nutrients when washing. Therefore, the patented rice produced by patented technology-preserved embryo and non-washable rice from aleurone layer must be the development direction of rice and the upgraded products of current standard rice.
How to preserve germ rice
The normal storage time of germ rice is 90 days. Because of the preservation of germ rice, three key factors should be considered: temperature, humidity and ventilation. The packaging is kept in a vacuum state, so the storage time is appropriately prolonged.
It can be refrigerated in the refrigerator. If you open the seal, you can put it in a container and put it in the refrigerator for refrigeration. If you don't have a refrigerator, you can put it in the shade of the balcony, keep it well ventilated and let the rice dry. Germ rice is freshly ground and fresh. Coupled with appropriate preservation methods, it can be preserved normally for 90 days.
If you put it in the cupboard and live in other places for too long, it depends on whether it is moldy. You can take some rice and soak it in water 10 minute. Take it out and rub it on your hands. If you can erase the black spots, it will be moldy. Generally, the mildew range is relatively large, and there are not only black spots on the germ.
