摘要
Abstract
The benzo(a) pyrene was extracted from animal and vegetable fats and oils by liquid phase ex- traction according to GB/T 24893 - 2010 Animal and vegetable fats and oils - Determination of polycyclic aromatic hydrocarbons, which was purified by solid phase extraction of neutral alumina column, and de- termined by reverse -phase high performance liquid chromatography - fluorescence method. The results indicated that the average recovery rate for vegetable fats and oils was 91.44%, and that for animal fats and oils was 91.69%. The relative standard deviation was 1.48% (n = 7 )for the determination results of tea seed oil. This revised method was simple and easy to operate, had good precision and high rate of re- coveries. Thus the revised method was fit for determination of benzo(a) pyrene content in animal and veg- etable fats and oils.关键词
