Study on Determination of Benzo(a) pyrene Content in Naan Products by High-Performance Liquid Chromatography

QIAO Gui-fang,F(xiàn)ENG Zuo-shan,AN Bi-fang,CHEN Chuang-ye, TAO Yong-xia* (College of Food Science and Pharmacy, Xinjiang Agricultural University,Urumqi 830o52,China) Abstract:Benzo(a)pyrene (Bap)is a carcinogenic substance that is easily found in food and is harmful to human health. In order to rapidly determine the content of Bap in Naan products,in this study,the method for the rapid determination of Bap by high-performance liquid chromatography(HPLC) is optimized.The sample is extracted with acetonitrile. Under the conditions of PLATISILTM ODS liquid chromatography column (250mm×4.6mm , 5μm );mobile phase:acetonitrile:water is 88:12 ;flow rateis 1mL/min ,column temperature is 24.5°C ,injection volume is 10μL ,fluorescence detector: excitation wavelength is 384nm and emission wavelength is 406nm ,the content of Bap is determined,and the standard curve is drawn. The regression equation is Y=1 047 259X+101 946 ,with R2=0.9995 . The average spiked recovery rates are between 68.58% and 95.10% , the RSD values range from 0.69% to 1.38% , the limit of detection of benzo(a) pyrene is 0.09μg/kg ,and the limit of quantification is 0.31μg/kg The Bap content in four kinds of Naan products is determined. The results show that the content of Bap all does not exceed the national limit of 2μg/kg . This method is easy to operate,efficient,with high recovery rate and reliable results,and it is suitable for the determination of Bap in Naan products.
