| World rice production is close to 650 million metric tons (MMT) of paddy rice in 2008 which constitutes more than a quarter of all cereal grains, and rice is the staple food for large portion of the world population. White or polished rice is obtained by first removing hull and abrading away the bran layer. Rice Bran comprises about 8% of paddy. The bran fraction contains almost all of the oil and the majority of protein, ash, vitamins and fiber of the rice caryopsis. |
