摘要
建立了白酒接触塑料制品中双酚A、双酚F、双酚S的超高效液相色谱-串联高分辨质谱的检测方法。双酚A、双酚F、双酚S在食品模拟液中经过一定时间和温度后发生迁移,以0.1%氨水-甲醇为流动相洗脱,经C18色谱柱分离,结合加热电喷雾电离源,在负离子模式下采用Full MS/ddMS^(2)进行分析;该方法在2.50~500.00μg/L质量浓度内线性良好,相关系数R^(2)均大于0.990,双酚S、双酚F和双酚A检出限分别为0.98、1.06、1.12μg/L,加标回收率为95.70%~117.53%,相对标准偏差为1.00%~3.55%。该方法灵敏度高、操作简便、定性准确性高,适用于白酒接触塑料制品中双酚A、双酚F、双酚S的检测,为开展酒类食品安全监管提供有效的技术支撑和理论参考。
Bisphenol A(BPA),bisphenol F(BPF),and bisphenol S(BPS)in baijiu-to-plastic products was detected by ultra performance liquid chromatography tandem high resolution mass spectrometry.BPA,BPF,and BPS dissolved in the food simulation solution,would migrate to the packing material under a certain time and temperature.They were separated with C18 column,analysed in Full MS/ddMS^(2)pattern under negative ion mode equiped a heated electrospray ionization source.This method showed a good linearity in the mass concentration range of 2.50-500.00μg/L(R^(2)>0.990),the recoveries were 95.70%-117.53%,the relative standard deviations were 1.00%-3.55%and the limits of detection of BPS,BPF,and BPA were 0.98,1.06,1.12μg/L,respectively.The method showed high sensitivity,simple operation and high qualitative accuracy suited for the determination of BPA,BPF,and BPS in baijiu contacting plastic products.It would provide effective technical support and theoretical reference for the development of wine and food safety supervision.
