Abstract:

In this work, a high⁃performance liquid chromatography⁃mass spectrometry (HPLC⁃QQQ) method to establish to determine the migration of bisphenol⁃A in food⁃contact materials and validate the feasibility of the detection method of bisphenol⁃A by using coffee cups as a detection object. The determination of bisphenol⁃A migration in food contact materials could be realized through such a method with good repeatability, stability, within⁃day precision, and day⁃to⁃day precision. The quantitative limit was 0.10 mg/kg, the detection limit was 0.01 mg/kg, and the spiked recovery rate was 99.35 %. In the concentration range of 0~1.0 mg/L, the concentration of bisphenol⁃A is positively correlated with the peak area, exhibiting a good linear relationship. This method is simple, fast, and accurate in the quantitative and qualitative analyses and can meet the requirements of determination for the bisphenol⁃A migration in food⁃contact materials.

Key words: food contact material, bisphenol A, liquid chromatography?mass spectrometry, migration volume, method validation
