Abstract
The oil of the rice bran can be hydrolyzed into serious of acids by lipase.According to the change of the index of free fatty acids, the effect of microwave radiating on the lipase of rice bran was studied. The results show that using the high power of microwave stove,250 g rice bran with moisture 12%～14% is radiated by microwave for 8 min,the treated rice bran can be safely stored for a month,and the change of index of free fatty acids is less than 25 mgKOH/g.
