摘要
为进一步增加燕麦油作为食用油的开发价值,对石油醚、正己烷、异丙醇、乙酸乙酯和乙醇五种溶剂提取的燕麦油进行精炼,对精炼油的DPPH·清除及还原力进行研究,并同大豆油进行比较。研究结果发现,精炼后的油脂,其还原力与DPPH·清除率都低于毛油,且随提取溶剂极性的增强而增强,精炼后的不同溶剂提取的燕麦油和大豆油DPPH·清除率分别为:石油醚75.94%、正己烷74.98%、异丙醇75.38%、乙酸乙酯79.37%、乙醇82.81%、大豆油69.53%;还原力分别为:石油醚0.45、正己烷0.44、异丙醇0.48、乙酸乙酯0.46、乙醇0.52、大豆油0.32。此外,各种燕麦油的还原力与DPPH·清除率显著高于大豆油。
In order to further increase the oat oil utilization value as edible oil, oat oil extracted by petroleum ether, hexane,isopropanol, ethyl acetate and ethanol, and soybean oil were refined to compare their differences in reducing power and DPPH · scavenging activity.The study results showed that the reducing power and DPPH · scavenging activity of refined oils were lower than crude oil, and the trend enhanced with the extraction solvent polarity increasing, DPPH ·scavenging rate of different refined oils were petroleum ether 75.94%, nhexane 74.98 %, isopropyl alcohol 75.38 %, acetic ether ？9.3？ %, ethanol 82.81 %, respectively and soybean oil was 69.53 %. Reducing power were petroleum ether 0.44, n-hexane 0.45, isopropyl alcohol 0.48, ethyl acetate 0.46, ethanol 0.52 respectively and soybean oil was 0.32.1n addition, various oat oils antioxidant capacity were significantly higher than the soybean oil .
