Determination and distribution of polycyclic aromatic

Muscle and liver samples of bream from the river Elbe contained little or no detectable amounts of PAH, whereas fresh and canned oysters and mussels showed higher contaminations. Highest PAH concentrations have been determined in “smoked oysters in oil” with 75.8 μg/kg benzo[a] pyrene for the oil and 12.2 μg/kg for the oyster meat.

However, total PAH concentrations increased slowly during deep-frying, especially during the deep-frying of chicken nuggets.
  • Does deep frying time affect PAH concentrations in edible oils?
  • The results of the present study show an increasing trend for concentrations and types of PAHs in edible oils with increasing deep-frying time. The main PAHs found in the samples (including fresh and deep-fried edible oils) were LM-PAHs. Four PAHs dominated the deep-fried peanut and olive oils.
  • Does frying oil contain PAHs?
  • Pearson correlation coefficients (PCC) for total polar components, polar components composition and PAHs in frying oils. Note: * p < 0.05; ** p < 0.01. The significant correlations between PAHs, polymerized products, and oxidized products show that the PAHs contents in frying oils can be reduced by controlling the degree of oil oxidation.
  • Does oxidation affect PAH content in frying oil?
  • The significant correlations between PAHs, polymerized products, and oxidized products show that the PAHs contents in frying oils can be reduced by controlling the degree of oil oxidation. However, the correlation mechanism between PAH value changes and oxidation and between PAH value changes and polymerization require further research.
  • Do edible oils contain PAHs?
  • The results show that all four fresh (unused) edible oils contain PAHs (189.9–2754.8 μg/kg) and mainly low-ring (2- to 4-ring) PAHs. PAH concentrations in the edible oils increased with increasing deep-frying time, especially among the high-ring (5-ring and above) PAHs.
