Omega 3, 6 and 9 fatty acids (FA), functional components of vegetable oils, are proved to be beneficial to health. For this reason, several oils are being used as food supplements. This work describes a validated method for FA determination in vegetable oils supplements containing palmitic, stearic, oleic, linoleic and α-linolenic FA employing capillary electrophoresis and a straightforward sample preparation. Avocado, carthamus, evening primrose and linseed oils were successfully analyzed in less than 9 min, showing a great potential of this method for a faster monitoring of FA. Accuracy tests revealed no significant difference between the present method and the classic gas chromatography method within the 95% confidence interval and slight values of relative standard deviation were found for inter- and intraday reproducibility tests (<3%).
