标准范围

本国际标准规定了使用毛细管柱测定植物油和脂肪中反式脂肪酸异构体含量的气相色谱法。该方法专门设计用于通过单个毛细管气相色谱(GC)程序评估植物油或脂肪在(高温)精炼过程中或在氢化过程中形成的反式异构体的水平。该方法还可用于报告来自相同样品和相同分析的所有其他脂肪酸(例如，以获得饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸的全脂肪酸组成和总量)。

This International Standard specifies a gas chromatographic method using capillary columns for the determination of the content of trans fatty acid isomers of vegetable oils and fats.The method is specially designed to evaluate, by a single capillary gas chromatographic (GC) procedure, the level of trans isomers as formed during (high temperature) refining, or during hydrogenation of vegetable oils or fats.The method may also be used to report all other fatty acids (e.g. to obtain the full fatty acid composition and total amounts of saturated fatty acids, mono-unsaturated fatty acids and poly-unsaturated fatty acids) from the same sample and same analysis.
