<p>This International Standard specifies a gas chromatographic method using capillary columns for the determination of the content of <i>trans</i> fatty acid isomers of vegetable oils and fats.</p>
<p>The method is specially designed to evaluate, by a single capillary gas chromatographic (GC) procedure, the level of <i>trans</i> isomers as formed during (high temperature) refining, or during hydrogenation of vegetable oils or fats.</p>
<p>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.</p>
