Abstract: 

The high annual rate of production of rice in our country usually resulted in accumulation of a large quantities of bran. This fact prompted us to evaluate different utilization of the rice bran. For this purpose, crude rice bran oil extracted from bran with commercial n- hexane by automatic sox let extractor and desolventized by rotary vacuum evaporator. Then crude rice bran oil was dew axed by chilling to 18 C followed by centrifuging . The wax sludge obtained was 66% free fatty acids and 34% waxes, whereas the oil phase was 64.5% fatty acids and 35.5% glycosides. The dew axed oil was evaluated as an antifoaming agent for aqueous media and compared to commercial oleic acid. Based on our results and findings, the dew axed rice bran oil has an antifoaming power equal or greater than oleic acid.
