摘要 以油茶籽为原料,研究微波和红外处理对压榨油茶籽油VE中4种生育酚异构体含量的影响。结果表明:油茶籽毛油中α-生育酚含量较高(0.24~0.41 mg/g),β-、γ-、δ-生育酚含量低于检测限;油茶籽仁和油茶籽压榨毛油中α-生育酚初始含量存在一定差异;最佳处理条件为微波功率560 W,红外温度130℃;两种处理方式均加速了油茶籽中VE的溶出和转化;微波处理比红外处理对α-生育酚影响更大。 The effects of microwave and infrared radiation treatment on the contents of four tocopherol isomers of VE in oil-tea camellia seed oil were studied. The results showed that the content of alpha-tocopherol in crude oil-tea camellia seed oil was higher(0.24-0.41 mg/g), and the contents of beta-, gamma-tocopherol and delta-tocopherol were lower than the detection limit. There were some differences in the initial content of alpha-tocopherol between oil-tea camellia seed kernel oil and oil-tea camellia seed oil. The optimal treatment conditions were obtained as follows: microwave power 560 W, infrared radiation temperature 130℃. The content of VE in oil-tea camellia seed was accelerated to dissolute and transform by the two treatments. Microwave treatment had larger influence on alpha-tocopherol than infrared radiation treatment.
