摘　　要：随着社会的不断发展,人们越来越重视自己的健康,对食用油品质的要求越来越高。脂肪酸的组成在很大程度上决定了食用油的营养价值和保健功效。以亚麻籽、葵花籽、核桃为例,利用气相色谱法分析其主要脂肪酸的含量。三类油料作物脂肪酸组成中必需脂肪酸的含量分别是:亚麻籽65.56%,葵花籽78.50%,核桃69.77%,与动物油脂中必须脂肪酸的含量相比明显较高。With the development of society, the health is important to people. It is call for a high quality of the edible oil. The. components of the fatty acids determine the nutritive value and health effects of the edible oil. The content of fatty acids and essential fatty acids in flaxseed, sunflower seed, walnut was analyzed by Gas Chromatography. The results showed that the content of essential fatty acids are as follows： Flaxseed 65.56%, Sunflower seed 78.50%, Walnut 69.77%. This content is significantly higher than animal oil.
