A study was undertaken to determine if gas plasma irradiation exerted any influence on the stability of the oil in rice bran or brown rice, and to ascertain if the petroleum ether-extractable lipids from irradiated bran or brown rice differed from that extracted from nonirradiated controls. The rate of free fatty acid development in the lipids of stored brown rice and in the stored bran separated from rice kernels was much slower in irradiated samples than in nonirradiated controls. Gas plasma irradiation profoundly changed the chemical and physical characteristics of rice oil from both stored brown rice and stored separated rice bran. The average molecular weight of the oil extracted from irradiated rice bran had increased. In addition, the oil was less saturated than that of the nonirradiated controls. The investigation demonstrated that these changes are effected specifically by the gas plasma irradiation rather than by the coincidental heat-vacuum effect of irradiation. The physical changes in the characteristics of the oil brought about by irradiation may be of significance in the technological uses of this product. (BBB)
