| 摘 要： | 本文对不同种植物油中的雏生素E和植物甾醇等可能的抗氧化成分做了定性定量分析。并结合自由基清徐试验和加速氧化试验。探讨了这些微量物质在油脂氧化过程中的作用。结果表明:不同的植物油中微量物质的种类和含量都存在一定的差异,而这种差异也导致了植物油抗氧化能力各异。比如月见革油和玉米油都有着较好的由由基清除能力。而油茶籽和松子油的则相对弱一些。多酚含量最高的橄榄油的氧化诱导时间长达14h。

| Abstract: | Antioxidants （like VE and phytosterols, and so on） in different kinds of vegetable oils were carried out qualitative and quantitative analysis. Combined with radical scavenging test and accelerated oxidation test, roles of these trace substances in fat oxidation process were discussed. Results showed that different types and levels of trace substances in vegetable oils there were some differences, but these differences also led to antioxidant capacity of different vegetable oils, such as evening primrose oil and corn oil had a better free radical scavenging capacity, and tea seed oil and pine oil relatively weak. The highest polyphenol content of olive oil oxidation induction time was 14h. |
