用气相色谱法分析了9种植物油和鱼油中脂肪酸组成和含量。结果显示:植物油之间最大的区别在于油酸与亚油酸的含量上,亚麻籽油则以亚麻酸含量最丰富,植物油几乎都不含有EPA和DHA。植物油的合理搭配必将在水产饲料中有着广泛的应用。
The composition and content of fatty acids in nine vegetable oils and fish oils were analyzed by gas chromatography. The results showed that the biggest difference between vegetable oils was the content of oleic acid and linoleic acid, while linseed oil had the highest content of linolenic acid, almost no vegetable oil contained EPA and DHA. The rational match of vegetable oil will have a wide range of applications in aquatic feed.
