摘要：The aim of the present study was to evaluate the effects of grilling temperatures on the formation of heterocyclic aromatic amines (HAAs) in steaks from the pork loin ( longissimus lumbo rum muscle). Grilling was carried out on a double hot plate grill set to the usual grilling temperatures of 120 °C to 280 °C and stopped when the internal temperature of 72 °C was reached. Among individual HAAs, the most abundant was 2-amino-1-methyl-6-phenylimidazo(4,5-b)pyridine (PhIP), as a maximum of 28.62 ng g–1 pork steak. in general, the total HAA levels increased with increasing grilling temperature. Higher HAA levels were observed at 260 °C compared to 240 °C, at 13.97 ng g–1, as a 68.7% increase. The highest total HAA levels were found at 280 °C (29.64 ng g–1 grilled pork steak), as a 258.0% increase compared to 240 °C. These data indicate that the formation of potentially carcinogenic HAAs during the grilling of pork steaks can be minimised by the using of lower grilling temperatures (≤ 240 °C).
