A gradient reversed-phase liquid chromatography with fluorescence detection method for simultaneous identification and quantification of bisphenol-A-diglycidyl ether (BADGE), bisphenol-F-diglycidyl ether (BFDGE), and their 10 derivatives in food matrixes was developed and validated for the analysis of oil-in-water- and aqueous-based foodstuffs. The method linearity range 0.016-10 ppm which are hundred-fold below and tenfold above the EU restriction at 1 ppm (mg/kg). The method detection limits range 0.72-4.20 ppb and the method quantitation limits range 2.40-14.85 ppb, respectively. The validation data indicate excellent precision, acceptable recovery, and good robustness, all supporting a good potential to further develop the method as a standard method for the determination of migrations from interior can coatings into foodstuffs.
建立了一种采用荧光检测的梯度反相液相色谱法,用于同时鉴定和定量食品基质中的双酚A - 二缩水甘油醚(BADGE)、双酚F - 二缩水甘油醚(BFDGE)及其10种衍生物,并针对水包油型和水性食品的分析进行了验证。该方法的线性范围为0.016 - 10 ppm,分别比欧盟1 ppm(mg/kg)的限制低百倍和高十倍。该方法的检测限范围为0.72 - 4.20 ppb,定量限范围分别为2.40 - 14.85 ppb。验证数据表明该方法具有出色的精密度、可接受的回收率和良好的稳健性,所有这些都支持将该方法进一步开发成为测定内涂罐涂料向食品迁移的标准方法的良好潜力。
