摘要
Changes in polycyclic (PAH) and oxygenated (OPAH) aromatic hydrocarbon concentrations in vegetable oils during storage for 270 days at 25 degrees C or 4 degrees C were investigated. The concentrations of OPAHs and PAHs increased with storage time. The increase in PAH concentration was mainly caused by light PAHs. Total PAH concentrations increased from 33.11-36.77 mu g/kg to 45.12-58.04 mu g/kg in 26 crude oil samples, while those in 26 refined oil samples increased from 16.52-20.02 mu g/kg to 25.73-40.01 mu g/kg. Acid value (AV) and peroxide value (POV) also showed an increase during the storage process from 0.08-0.92 mg/kg to 0.33-2.98 mg/kg, and from 0.08-0.12 mmol/kg to 0.33-3.45 mmol/kg in 52 tested oils, respectively. AV and POV were within the regulatory limits of China after storage for 270 days. However, concentrations of 16 PAHs in all tested oils exceeded 25 mu g/kg. The results indicated PAHs and OPAHs formation was better inhibited in oils stored at lower temperature. (C) 2017 Elsevier Ltd. All rights reserved.
