시중에 유통되는 식용유지 중 benzo[a]pyrene 함량 분석

Concentrations of benzo[a]pyrene in edible oils from Korean market were evaluated by high performance liquid chromatography. Benzo[a]pyrene known of the carcinogenic polycyclic aromatic hydrocarbons(PAHs), has been found at variable concentrations in several foods. This is associated with several factors during the process including contaminated raw materials, exposure of environment, and procedure of process or cooking. The levels of benzo[a]pyrene were ranged from 0.5 to 1.4 μg/kg in virgin olive oil. Benzo[a]pyrene contents in refined and virgin olive oil, sesame oil, soybean oil, corn oil, sunflower oil, safflower oil, and processed oil were 0.6-1.0 μg/kg, 0.9- 1.3 μg/kg, 0.6-3.3 μg/kg, 0.5-1.1 μg/kg, 1.2-1.7 μg/kg, 1.0-2.1 μg/kg, and 1.0-1.4 μg/kg, respectively.
