  • Method for stabilizing rice bran and rice bran products
    Patent number: 5512307
    Abstract: 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. Stabilized rice bran has food and industrial utility and can be processed by a sequence of steps including wet milling and microfiltration into a variety of other products also having food and industrial utility. In some instances depending on the product, it is not necessary to stabilize the rice bran before wet milling and microfiltration.
