BS EN ISO 12966-4:2015规定了测定衍生脂肪酸甲酯（FAME）的方法 通过毛细管气相色谱法将脂肪、油和脂肪酸进行酯交换或酯化 （GLC）。从C8到C24的脂肪酸甲酯可以使用ISO 12966的这一部分进行分离，包括 饱和脂肪酸甲酯、顺式和反式单不饱和脂肪酸甲酯以及顺式和反式单不饱和脂肪酸甲酯 反式多不饱和脂肪酸甲酯。该方法适用于粗、精制、部分氢化或完全氢化的脂肪、油和脂肪 来源于动物和植物的脂肪酸。该方法不适用于乳制品、反刍动物脂肪和油或补充产品的分析 与共轭亚油酸（CLA）结合。牛奶和奶制品（或来自牛奶和奶制品的脂肪） 不在ISO 12966本部分的范围内。ISO 12966的本部分不适用于二、三、聚合和氧化脂肪酸以及脂肪和油。交叉引用:ISO 661ISO 3696ISO 6353ISO 12966-2ISO 12966-3购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN ISO 12966-4:2015 specifies a method for the determination of fatty acid methyl esters (FAMEs) derived by transesterification or esterification from fats, oils, and fatty acids by capillary gas chromatography (GLC). Fatty acid methyl esters from C8 to C24 can be separated using this part of ISO 12966 including saturated fatty acid methyl esters, cis- and trans-monounsaturated fatty acid methyl esters, and cis- and trans-polyunsaturated fatty acid methyl esters.The method is applicable to crude, refined, partially hydrogenated, or fully hydrogenated fats, oils, and fatty acids derived from animal and vegetable sources.This method is not suitable for the analysis of dairy, ruminant fats and oils, or products supplemented with conjugated linoleic acid (CLA). Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this part of ISO 12966.This part of ISO 12966 is not applicable to di-, tri-, polymerized and oxidized fatty acids, and fats and oils.Cross References:ISO 661ISO 3696ISO 6353ISO 12966-2ISO 12966-3All current amendments available at time of purchase are included with the purchase of this document.
