A process for stabilizing rice bran containing protein and a naturally occurring lipase enzyme that causes rancidity. The rice bran is treated with an antilipase enzyme, preferably a nonspecific protease of plant or fungal origin. Treatment with the antilipase enzyme stabilizes the rice bran against rancidity without denaturing the protein.
