Effects of cooking methods and tea marinades on the formation of benzo[a]pyrene in grilled pork belly (Samgyeopsal)

Publication date: July 2017 Source:Meat Science, Volume 129 Author(s): Keun-Cheol Park, HeeSoo Pyo, WooSeok Kim, Ki Sun Yoon We investigated the effects of different grilling tools, temperatures, and tea marinades on the formation of benzo[a]pyrene in grilled pork belly as well as the antioxidant capacities of tea marinades. The least amount of benzo[a]pyrene was detected in modified charcoal-grilled pork belly (1.28μg/kg). The highest risk factors for the formation of benzo[a]pyrene are direct contact with flames and fat excess on the heating source. A modified charcoal grill can be used as an alternative grilling tool to meet consumer needs for safety and taste. The marination of pork bellies with tea increased radical-scavenging activity and prevented lipid oxidation in proportion to the concentration of tea infusion and marinating time. The yerba mate tea marinade significantly increased the radical-scavenging activity and prevented benzo[a]pyrene formation more than the green tea marinade. Tea marinade can be applied to seasoning or sauce as pretreatment to preserve the quality of meat and to decrease benzo[a]pyrene formation during cooking.
