| 摘 要： | 将茶多酚进行分子化学修饰成脂溶性（ＬＰ），具有茶多酚的鉴别特征，且毒副作用低。ＬＴＰ能明显延长油脂过的诱导期，但从色拉油的ＰＯＶ值和硫代巴比妥酸反应物（ＴＢＡＲＭ）形成抑制率测定表明，相同重量浓度的ＬＴＰ的抗氧化能力稍弱于叔丁基对苯二酚（ＴＢＨＱ）。采用正交设计，发现没食子酸、柠檬酸和ＬＴＰ具有有协同抗氧化作用，５０ｐｐｍ没食子酸＋５０ｐｐｍ柠檬酸＋１００ｐｐｍＬＴＰ、１００ｐｐｍＬＴＰ、１２００ |

| Abstract: | Lipid-soluable tea polyphenols (LTP)which were derivative from tea polyphenols (TP) molecular modification had the same discriminating property as TP.The POV-time curve of oil peroxidation complemented with LTP showed that LTP markedly prolonged the inducing period of oil peroxidation.The POV value and TBARM inhibition of oil showed the antioxidantive effect of tertbutyl hydroquinone (TBHQ) was more strengthened than that of LTP under the same concentration.It was found by an orthogonal test design that LTP had cooperative antioxidation with gallic acid (GA) and citric (CA).The POV value inhibition of 100ppmLTP 50ppmGA 50ppmCA,100ppmmLTP,100ppm TBHQ was respectively 90.6%,65.7% and 92.9% . |
