以紫苏籽油、芝麻油、胡麻油、青花菜籽油、大豆油、花生油、玉米油、葵花籽油8种植物油为研究对象,比较不同种类植物油的脂肪酸组成、多酚含量和抗氧化性。结果表明:8种植物油脂肪酸组成比例各不相同,其中花生油中油酸含量最高,为43.98%,葵花籽油中亚油酸含量最高,为6500%,紫苏籽油中亚麻酸含量最高,为63.89%;8种植物油的DPPH自由基清除能力强弱顺序为芝麻油>大豆油>玉米油>青花菜籽油>胡麻油>花生油>紫苏籽油>葵花籽油,与其多酚含量一致;8种植物油的铁离子还原能力从大到小依次为芝麻油>大豆油>青花菜籽油>花生油>胡麻油>玉米油>紫苏籽油>葵花籽油。 |
英文摘要: |
The fatty acid compositions, polyphenol contents and antioxidant properties of eight kinds of vegetable oils, including perilla oil, sesame oil, flaxseed oil, broccoli oil, soybean oil, peanut oil, maize oil, and sunflower seed oil, were compared and discussed. The results indicated that the eight vegetable oils had different fatty acid composition ratios. Among them, peanut oil had the highest oleic acid content of 4398%, sunflower seed oil had the highest linoleic acid content of 65.00%, and perilla oil had the highest linolenic acid content of 63.89%.The DPPH free radical scavenging ability of eight vegetable oils decreased in the following order: sesame oil>soybean oil>maize oil>broccoli oil>flaxseed oil>peanut oil>perilla oil>sunflower seed oil, which was consistent with the polyphenol contents. While the Fe3+ reducing ability decreased in the following order: sesame oil>soybean oil>broccoli oil>peanut oil>flaxseed oil>maize oil>perilla oil>sunflower seed oil. |
