ANALYTICAL CONTROL BENZO(A)PYRENE IN VEGETABLE OILS - article

Method of analytical control of benzo(a)pyrene in vegetable oil excluding stage alkaline hydrolysis of vegetable oils was tested in investigation on the content of BaP in sunflower, corn, olive, flaxseed, pumpkin seed oil and walnuts by HPLC/FLD. Duration of a full analysis of one sample oil sample was 70 minutes. Studied range of concentrations of benzo(a)pyrene was 0.5 mg/kg and 10.0 mg/kg. Method meets requirements of DSTU 17025 and EU SANCO 12495-2011, which is confirmed by the appropriate validation characteristics. The developed method has been successfully applied in the inter-laboratory comparisons, performing routine analyzes for 2011-2012.

Keywords: benz(a)pyrene, high performance liquid chromatography, vegetable oil.
