摘要: 对市售的11种油样及二次油煎、多次油煎共计13种油制品进行脂肪酸的气相色谱法测定,并比较其脂肪酸含量以及对油煎、油样成分进行分析。结果表明,13种油样无显著差异,但各样品中油酸、亚油酸和亚麻酸3个指标存在不同程度的差异。

关键词: 食用油, 脂肪酸, 气相色谱法

Abstract: The fatty acids of 11 kinds of oil samples and 13 kinds of oil products in the market were determined by gas chromatography, and the fatty acid content and composition of oil samples were compared. Through the addition ratio of oleic acid, linoleic acid and linolenic acid, 13 kinds of oil samples had no significant difference, but for the three indexes of oleic acid, linoleic acid and linolenic acid of 13 all the oil samples were different.

Key words: edible oil, fatty acid, gas chromatography
