Determination of polycyclic aromatic hydrocarbons in fat products by high pressure liquid chromatography.

The method previously described by Gertz [1] for the extraction of 3,4-benzopyrene in meat- and fishproducts has been adapted for butter, margarine, edible oils and fats and extended to other polycyclic aromatic hydrocarbons (PAH): 1,2-benzopyrene, 1,2,3,4-dibenzanthracene, 1,2,5,6-dibenzanthracene and 1,12-benzoperylene. The isolated PAH are determined by high-pressure liquid chromatography on reversed-phase columns with detection by fluorimetry. Recoveries range from 76 to 85%.
