From rice hull (hull) and cortex (BRAN) process. Inatani Koyutani, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the lowest degree of fragmentation, and to make rice with better eating quality.

The cleaned rice husk removed (hull) and cortex (BRAN) process. Inatani Koyutani, cortex, embryo and endosperm. The weight percentage of each part: 18 ~ 21% hull, cortex around 6%, 66 ~ 70% endosperm embryos of 2 ~ 3%. Each part of the chemical composition of the difference (see table), the husk fiber containing up to 40%, there is not much nutritional value; the cortex contains rich protein and fat, but also more fiber; embryo contains protein, fat and vitamin A; endosperm containing carbohydrates, fiber at least. The purpose of rice processing is to separate the endosperm from other parts with the lowest degree of fragmentation, so as to make rice with better eating quality.
