Abstract

The effect of different amount of onion and turmeric as marinade ingredients on the formation of polycylic aromatic hydrocarbons (PAHs) was evaluated by comparing the concentration of PAHs in beef satay marinated in five different marinade treatments. PAHs were analyzed by high performance liquid chromatography with fluorescence detection. The detection limit of 15 PAHs were obtained ranged from 0.07 to 0.98 ng/g. The linearity of the method was between 0.9998 to 1. The concentration of Benzo(a)pyrene in all beef satay samples exceeded the maximum limit set by European Union whicft was 5 ng/g. This study showed that marinade treatments with the highest amount of onion (Marinade 2) and turmeric (Marinade 4) could lower the concentrations of Benzo(a)pyrene and able to reduce total concentrations of sum of PAH4 (Benzo(a)anthracene, Chrysene, 8enzo(b)fluoranthehe and Benzo(a)pyrene) up to 20.4% and 18.8% respectively as compared to Control. These results revealed that onion and turmeric as ingredients in marinade treatments have reduction effect on the formation of PAHs in grilled beef satay.
