Although consumer awareness and demand about healthier foods have been increased in recent years, consumption of white rice instead of brown rice is much more common worldwide. However, owing to the concentration of many vitamins and minerals in the bran and germ, rice milling results in the loss of 76% of thiamine, 57% of riboflavin, 63% of niacin and 80% of iron (Saunders, 1985). Rice bran, which comprises pericarp, aleurone layer, germ and some endosperm, is a nutritionally valuable by-product of rice (paddy) milling. It contains 34–62% starch, 15–22% crude fat, 11–15% protein, 24–29% dietary fibre, and 6.6–9.9% minerals (Juliano and Hick, 1996). Moreover, rice bran contains notable amounts of B vitamins (Saunders, 1985).
