a b s t r a c t Several countries have adopted labelling policy concerning the declaration of trans fatty acids (TFAs) content in the nutritional facts panel of processed food. Consequently, the food industry requires rapid methods to measure low levels of TFAs. This paper reports the development of a rapid method to determine TFAs
