Abstract

The chapter briefly reviews the use of high pressure liquid chromatography (HPLC) in the determination of intact triacylglycerols (TAGs), and quality assessment in edible seed oil with particular emphasis on oil products extracted by cold pressing. Cold pressing is a technique known to retain the bioactive compounds and essential fatty acids naturally present in the extracted oil. The TAG compositional data is an important and valuable indicator that provides the quantitative assessment of the quality, determining product authenticity and adulteration of cold pressed seed oils. The chapter also discusses various methods of analysing TAGs using reversed phase-HPLC and improvements made in the detection of TAGs eluted from HPLC.
