Abstract
U radu je proveden razvoj i validacija HPLC metode za određivanje policikličkih aromatskih ugljikovodika (PAH) u jestivim uljima na DACC (eng. donor-acceptor complex chromatography) koloni povezanoj online s HPLC sustavom s fluorescentnim detektorom. Metodom je određen udjel pojedinačnih PAH-ova u rafiniranom ulju suncokreta, djevičanskom maslinovom ulju, hladno prešanom bučinom ulju, tamnom sezamovom i nerafiniranom bučinom ulju proizvedenom uz prženje koja su nabavljena s domaćeg tržišta. Kalibracija i validacija napravljene su za 13 pojedinačnih PAH-ova među kojima je svih 8 PAH-ova koji se nalaze na listama prioriteta Europske zajednice i američke Agencije za zaštitu okoliša vezanim uz praćenje ovih spojeva u hrani i okolišu. Koeficijenti korelacije kalibracijskih pravaca u ispitivanom rasponu za sve spojeve bili su viši od 0,999, a svi parametri validacije bili su unutar granica koje propisuje europsko zakonodavstvo. Udjeli PAH-ova u hladno prešanom bučinom, nerafiniranom bučinom proizvedenom uz prženje i tamnom sezamovom ulju višestruko su premašili preporučene granice za udjel ukupnih PAH-ova, iako je udjel PAH-ova u bučinim uljima bio unutar propisanih. U tamnom sezamovom ulju nađen je visok udjel kancerogenih PAH-ova teške frakcije.
Abstract (english)
In this work an HPLC method for determination of polycyclic aromatic hydrocarbons (PAH) in edible oils on a DACC (donor-acceptor complex chromatography) column coupled with an on-line HPLC system with fluorescent detection. Method was used to determine the content of individual PAHs in the refined sunflower oil, virgin olive oil, cold pressed pumpkin seed oil, dark sesame and pumpkin seed oil produced with roasting obtained from domestic market. Calibration and validation were conducted for 13 individual PAHs that are listed as priorities by European Commission and US Environmental Protection Agency (EPA). Correlation coefficients of calibration curves for all standards were above 0.999, and all validation parameters were within limits set by European regulation. Content of PAHs in cold pressed pumpkin seed oil, roasted pumpkin seed oil and especially dark sesame oil was several-fold higher than the recommended limit, even though for pumpkin seed oils it was lower than limits. High content of cancerogenous heavy fraction PAHs were found in dark sesame oil.
