食品接触材料中双酚A分析方法的建立及验证
Establishment and validation of a method for analyzing bisphenol-A in food-contact materials
【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-today 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.
