超高效液相色谱-串联质谱法同时检测肉制品中17种合成色素的含量

Determination of 17 Kinds of Synthetic Colorants in Meat Products by UPLC-MS/MS

  • 摘要: 为了建立超高效液相色谱-串联质谱法(UPLC-MS/MS)同时快速检测肉制品中17种合成色素的方法。经水振荡提取样品,正己烷除油,弱阴离子固相萃取柱(WAX)富集净化,以乙腈-5 mmol/L乙酸铵为流动相进行梯度洗脱,采取负离子扫描,在多反应监测模式(MRM)下,使17种目标化合物在ACQUITY UPLC HSS T3反相色谱柱上分离,使用外标法定量。结果表明,17种目标化合物在20~1200 μg/L的线性范围内相关系数均大于0.99,方法的检出限为0.01~0.05 mg/kg,定量限为0.03~0.15 mg/kg。17种目标化合物在阴性基质中通过添加3个不同加标水平(0.15、0.30和1.0 mg/kg)进行回收率测试,不同水平下的回收率为71.2%~103.5%,相对标准偏差(RSDs,n=6)范围为1.3%~4.9%。该方法净化效果好、操作简单、定量准确,适用于肉制品中合成色素的快速筛查以及快速定量分析。

     

    Abstract: To establish a method for the rapid detection of 17 colorants in meat products by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS), samples were homogeneously extracted with water, degreased with n-hexane, enriched and purified with weak anion solid phase extraction (WAX) column. The seventeen compounds were separated on ACQUITY UPLC HSS T3 column by the gradient elution using acetonitrile-5 mmol/L ammonium acetate solution as mobile phase, detected by MS/MS with negative mode in multiple reaction monitoring (MRM) mode, and finally quantified by external standard method. The correlation coeffcients (r) of the seventeen compounds were above 0.99 in the mass concentration ranging from 20~1200 μg/L. The limits of detection and the limits of quantification of the method were 0.01~0.05 mg/kg and 0.03~0.15 mg/kg, respectively. The recoveries of seventeen analyses spiked at three levels (0.15, 0.30 and 1.0 mg/kg) in meat products ranged from 71.2% to 103.5% with the relative standard deviations (RSDs, n=6) ranged from 1.3%~4.9%. The method was easy to operate and with good purification effect. It could be applied to the rapid determination of the synthetic colorants in meat products .
