  • Intercomparison of methods for the determination of trans fatty acids in edible oils and fats and certification of three materials containing trans fatty acids


The aim of the first intercomparison was two fold. Firstly, to select, stabilize and bottle suitable materials containing ca 1%, 5% and 30% total trans fatty acids and demonstrate that packaging and storage does not affect oil composition, and secondly, to demonstrate that participating laboratories are able to achieve sufficient conformity of test results. The intercomparison was to be repeated with new sets of samples. Special emphasis will be placed on the correct identification of trans polyenes in order to improve precision for low levels of TFA. To facilitate correct identification, the Co-ordinator will distribute equivalent chain length data for TFA.
