Brown rice is the caryopsis of rice after rice husk is removed from the outer protective layer. The rice grains with complete inner protective layer (pericarp, seed coat and nucellar layer) have rough taste and dense texture because of more crude fiber and bran wax in the inner protective layer, which requires time to cook, but its slimming effect is remarkable.
