大豆富含脂肪和蛋白质。大豆油是世界上主要食用油之一,因此油的质量极为重要。降低大豆油中亚麻油酸含量,提高油脂的耐贮性是当前研究的课题之一。另一方面,不饱和脂肪酸,尤其是亚油酸含量高,对防止动脉粥样硬化,软化血管又有重要作用。因此,大豆油脂肪酸组成的研究近年来日益受到重视。 李莹等(1981)结合山西野生大豆资源考察,分析了部分山西野生大豆的脂肪酸组成,其中油酸含量为14.09—17.71％,亚麻油酸含量为19.82—20.35％。而晋豆3号分别为23.79％和8.19％。野生大豆的油酸含量低于栽培大豆,亚麻油酸含量远高于
Soy is rich in fat and protein. Soybean oil is one of the major edible oils in the world, so the quality of the oil is extremely important. Reducing the content of linoleic acid in soybean oil and increasing the storability of oil are one of the topics studied at present. On the other hand, high levels of unsaturated fatty acids, especially linoleic acid, play an important role in preventing atherosclerosis and softening blood vessels. Therefore, the research on the fatty acid composition of soybean oil has been paid more and more attention in recent years. Li Ying et al. (1981) combined with the investigation of wild soybean resources in Shanxi Province, and analyzed the fatty acid composition of some wild soybean in Shanxi. The content of oleic acid was 14.09-17.71% and the content of linoleic acid was 19.82-20.35%. While Jin Dou 3 were 23.79% and 8.19% respectively. Wild soybean oleic acid content is lower than that of cultivated soybean, linolenic acid content is much higher than
