title: Detection of polycyclic aromatic hydrocarbons in different types of processed foods.
abstract: Polycyclic aromatic hydrocarbons (PCAHs), particularly those with a high molecular weight, have been classified as probable carcinogens to humans. The aim of the present study is to determine the levels of PCAHs in samples of meat, fish, chicken, fried potato, and toasted bread, which will be thermally processed using conventional and microwave ovens. Different samples will be collected and analyzed for five PCAHs including pyrene, benzo(a)anthracene, benzo(e)pyrene, benzoflouroanthene, and benzo(a)pyrene. The analytical method involves saponification with methanolic potassium hydroxide, extraction with cyclohexane, and determination by high-performance liquid chromatography. The obtained results showed that there is a variation in the detected PCAHs in different foodstuffs. Fried potato processed by conventional oven or microwave oven showed none of the selected studied PCAHs. It was found that, chicken showed higher content levels of total PCAHs than the meat and fish. Data are the highest mean concentrations of fluoranthene and benzo(a)pyrene but within low limit. The obtained results were compared with international permissible levels to avoid pollution, which may cause hazardous effects on individual and society.
