Determination of Benzo[a]pyrene in Smoked Foods by High-performance Liquid Chromatography Based on Magnetic Solid Phase Extraction

Abstract

In this paper, a sensitive and practical method for the determination of benzo[a]pyrene (BaP) in smoked foods with HPLC-FLD was developed. In order to improve the detection limit of HPLC-FLD, we prepared magnetic nanoparticles with monomers of 4,4-bipyridine and cyanuric chloride (Fe3O4@TCLN) used as sorbent of magnetic solid-phase extraction (MSPE) to extract trace BaP from the samples. The recovery was 94.74% for BaP, and limit of detection (LOD) and limit of quantification (LOQ) was 0.09 µg/kg and 0.28 µg/kg, respectively. As the result of BaP analysis from the real smoked foods, the average BaP content was 5.68 µg/kg and the highest content of BaP was 6.12 µg/kg. The developed method is potential for the determination of Bap in food safety analysis and monitoring.
