Trans fatty acid determination by capillary zone electrophoresis: the state of the art and applications

Author affiliations

Abstract

A review taking into account literature reports covering alternative methods for trans fatty acid (TFA) determination, expressed in elaidic acid (EA), using capillary zone electrophoresis is presented. The manuscript presents ultraviolet-visible and capacitively coupled contactless conductivity detection systems. TFAs were separated by indirect detection, with the use of a chromophore agent in a background electrolyte as well by direct detection, without the use of the chromophore agent. In sum, the present review evidences that capillary electrophoresis (CE) is a very interesting analytical separation technique for TFA quantification in different matrices, which offers many advantages such as short analysis time, simple sample preparation, and use of short and non-specific columns and small amounts of organic solvents and reagents to perform experiments. These compensations make CE approaching very attractive to attend demand of governmental agencies and industries facing the global concern in respect of the harmful health effects caused by increasing intake of TFAs, as EA.
