摘　　要：以葵花籽油为介质,以过氧化值为指标研究了葡萄柚精油的抗氧化性能。结果表明:葡萄柚精油对葵花籽油有较强的抗氧化作用,且抗氧化效果与添加量有关;当精油添加量达到0.1%时抗氧化效果就已高于0.02%BHT;添加了葡萄柚精油的葵花籽油应在低温避光条件下保存;α-生育酚对葡萄柚精油的抗氧化作用起到增效作用。Sunflower seed oil as the medium,peroxide value as an indicator,study the antioxidant properties of essential oils of grapefruit.The results showed that： Grapefruit essential oil of sunflower oil had strong anti-oxidation and anti-oxidant had effects with addition;when added 0.1 % oil the anti-oxidant effect had been in excess of 0.02 % BHT;added grapefruit essential oils of sunflower seed oil should be stored at low temperature,under dark conditions;α-tocopherol on the antioxidant effect of grapefruit essential oils played a synergistic role.
