What is Gamma Oryzanol?

Rice bran oil is extracted from the bran fraction of rice, the kernels or seeds of the rice plant. It contains large amounts of gamma oryzanol, a mixture of antioxidant compounds. The outer chaff of the rice seed is milled off to produce brown rice; further milling removes the bran portion (the rest of the husk and the germ portions), creating white rice. The rice plant has long, slender leaves, and small wind-pollinated flowers. The species is native to South Asia and some parts of Africa but is cultivated widely. As a cereal grain, it is a major source of nutrition for a large portion of the world’s population.
