| 摘 要： | 目的]了解桂花总黄酮抗氧化的生理活性,为开发天然油脂抗氧化剂提供参考。方法]采用Schaal烘箱法研究了桂花总黄酮对不同油脂的抗氧化性能。结果]桂花总黄酮对4种食用油脂均有良好的抗氧化效果,且对菜籽油具有较强的抗氧化效果,其作用具有剂量效应关系;VC、柠檬酸、酒石酸对桂花总黄酮的抗氧化作用均有协同增效作用,与合成抗氧化剂相比,均能增加桂花总黄酮对油脂的抗氧化效果;桂花总黄酮添加量达0.02%时,抗氧化效果优于0.02%BHA。结论]桂花总黄酮添加到油脂中,既能起到抗氧化作用,延长含油食品的保质期,又有一定的保健作用。

| Abstract: | Objective] To study the antioxidation biological activity of total flavonoids in Osmanthus fragrans and provide reference for development of natural oil antioxidant.Method] Antioxidation activity of the total flavonoids of Osmanthus fragrans on edible oils was studied using peroxide value(POV) by Schaal oven-storage test.Result] The results showed that the total flavonoids are of good antioxidant effects on four edible oils.The activity on rapeseed oil is the strongest and dose-dependent.The total flavonoids of Osmanthus fragrans added with vitamin C,citric acid or tartaric acid exhibit remarkable synergistic antioxidation activity in lard.The antioxidation activity of the total flavonoids synergized with synthetic antioxidants such as BHA,BHT or PG is proved to be better than single antioxidant used.Conclusion] Adding total flavonoids of Osmanthus fragrans in oil not only can have antioxygenation effect,but also have health care. |
