摘要
建立快速测定饮料中16种食品添加剂的分析方法。样品中的食品添加剂用甲醇-水提取,在ACQUITY UPLC BEH C18色谱柱上分离,用二极管阵列检测器检测。结果表明,16种食品添加剂在5.5min内可获得良好的分离,各组分检出限均优于1.0mg/kg,加标回收率为91.6%～100.3%,RSD为0.66%～2.20%,表明该方法精密度良好。
An ultra performance liquid chromatographic （UPLC） method was presented for the rapid determination of 16 kinds of food additives in beverages. The method was based on extraction with methanol mixed with water, separation on an ACQUITY UPLC BEH C18 column and detection with diode-array detector. All the sixteen kinds of food additives were well separated within 5.5 minutes. The limits of detection for them were more than 1.0 mg/kg, and the recoveries at three spike levels were 91.6% - 100.3%, RSD was 0.66%- 2.20%.
