Abstract

Characterization of 15 polycyclic aromatic hydrocarbons (PAHs) in extra virgin, virgin, second centrifugation, lampante, refined, crude olive pomace, and refined olive pomace oils was carried out in 24 different types of olive oils and seven different types of pomace oils produced in Turkey and Spain. The extraction method was followed by liquid-liquid extraction, a solid phase clean up using C18 and Florisil cartridges, and evaporation. Then the evaporated residue dissolved in tetrahydrofuran/methanol 50:50 v/v, was analyzed by reversed phase high-performance liquid chromatography with fluorescence detector using two excitations (280, 256nm) and emission (410, 446nm) wavelenghts channels. PAHs content of crude and refined olive pomace oils were found higher than in the other oils. In the samples analyzed, the highest concentrations of PAHs corresponded to benzo[ghi]perylene, naphthalene, pyrene, acenaphthene, benzo[k]fluoranthene, and phenanthrene. © 2013 WILEY-VCH Verlag GmbH & Co.
