Abstract: More attention has been paid to trans fatty acids (TFAs) because of its influence on the human health. Adequate analytical tools are required for determining the contents of TFAs in labeling food products. Several different analytical methods such as spectrometry, chromatography, mass spectrometry and electrophoresis have been developed for analyzing TFAs in food products. This paper reviews the analytical methods developed for identifying and quantifying TFAs in oils and fats, describes the related merits of these approaches and their applications in food analysis.

Key words: determination, food product, review, trans fatty acids (TFAs)
