| Abstract: | A new rapid method has been developed to determine polycyclic aromatic hydrocarbons (PAHs) in edible fats and oils. Samples are dissolved in isohexane/butylmethylether and PAHs are adsorbed onto a polystyrene solid‐phase extraction cartridge. Triglycerides and non‐aromatic components are eluted stepwise with different mixtures of isohexane and butylmethyether. PAHs finally are eluted with tetrahydrofurane. After evaporation of solvent, PAHs are redissolved in acetonitrile and analysed by RP‐HPLC with fluorimetric detection. Recoveries of 5‐ and 6‐nuclear PAHs are 85—95%, recoveries of 4‐nuclear PAHs are about 60—75%, for 2‐ and 3‐nuclear PAHs the solid‐phase extraction method is not suitable. |
