Abstract:

An accelerated solvent extraction followed by gas chromatography-mass spectrometric method was presented for determining bisphenol A in candy packaging materials. Samples were extracted with a mixture (7:3, V/V) of dichloromethane and acetone in an accelerated solvent extractor, derivatized with a commercial BSTFA-TMCS mixture prior to GC-MS analysis. Mean spike recoveries of bisphenol A at three levels were between 75.2% and 90.7%, and the limit of detection (LOD) of bisphenol A was 5 μg/kg. This method has the characteristics of simplicity, high accuracy and precision and good reproducibility.

Key words: bisphenol A, accelerated solvent extraction, candy packaging materials, gas chromatography-mass spectrometry (GC-MS)
