摘要:

建立高效液相色谱质谱联用法(HPLC⁃QQQ)对食品接触材料中的双酚A迁移量进行测定,以咖啡杯为检测对象,验证双酚A检测方法的可行性。该法实现了双酚A迁移量在食品接触材料中的测定,重复性、稳定性、日内精密度及日间精密度良好,定量限为0.10 mg/kg,检出限为0.01 mg/kg,加标回收率为99.35 %。在0~1.0 mg/L浓度范围内,双酚A的浓度与峰面积成正相关,线性关系良好。该方法操作简便、快捷、定量定性精确,能满足双酚A迁移量在食品接触材料中的测定。

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
