摘要/Abstract

摘要： 茶多酚是茶叶中提取的一种天然抗氧剂,具有优良的抗氧性能。本文将茶多酚加入月见草油中进行抗氧化性实验,以过氧化值(POV)和酸值为指标,考查了月见草油对紫外光和超声波辐射的稳定性。实验结果表明,用紫外光或超声波辐射7h,添加10×10-6、20×10-6、30×10-6、40×10-6、50×10-6茶多酚的月见草油的过氧化值(POV)比不加茶多酚分别低40.17%、44.04%、49.94%、58.41%、66.01%和14.59%、32.67%、35.49%、43.44%、64.92%。用紫外光或超声波辐射7h,添加50×10-6茶多酚的月见草油的酸值比不加茶多酚分别低38.71%和29.63%。由此说明月见草油中添加茶多酚具有良好的抗光敏氧化和抗超声辐射作用。

Abstract: The tea polyphenols, extracted from tea, is natural antioxidant inhibitor with optimal resistance to oxidation capability. Using peroxide value (POV) and acid value for object, the stabilization of Oneothera Biennis oil on ultraviolet light and ultrasonic radiation with tea polyphenols addition was investigated by anti-oxidation experiment. The results show that during ultraviolet light for 7 hours with 10×10-6, 20×10-6, 30×10-6, 40×10-6 and 50×10-6 of tea polyphenols, the peroxide values (POV) of Oneothera Biennis oil addition content decrease by 40.17%, 44.04%, 49.94%, 58.41% and 66.01% in comparison with that without tea polyphenols, respectively. During ultrasonic radiation for 7 hours with 10×10-6, 20×10-6, 30×10-6, 40×10-6 and 50×10-6 of tea polyphenols addition content, the peroxide values of Oneothera Biennis oil decrease by 14.59%, 32.67%, 35.49%, 43.44% and 64.92% in comparison with that without tea polyphenols, respectively. The acid values of Oneothera Biennis oil with 50×10-6 of tea polyphenols content decrease by 38.71% and 29.63% in comparison with that without tea polyphenols during ultraviolet light and ultrasonic radiation for 7 hours, respectively. So the tea polyphenols show optimal effects on anti-photosensitivity oxidation and anti-ultrasonic radiation for Oneothera Biennis oil.
