摘要

关于含蛋产品中抗生素残留的报道很少。本研究建立了一种基于改进的QuEChERS制样技术-超高效液相色谱-串联质谱联用技术同时测定两种速溶糕点中24种磺胺类抗生素的有效方法。结果表明，在5、10、50 μg kg-1浓度下，sa的平均加样回收率为67.6% ~ 103.8%，相对标准偏差(RSD)为0.80 ~ 9.23%。检出限为0.01 ~ 0.14 μg kg-1，定量限为0.02 ~ 0.45 μg kg-1。该方法适用于速溶糕点中24种砷的分析。

Determination of 24 sulfonamide antibiotics in instant pastries by modified QuEChERS coupled with ultra performance liquid chromatography-tandem mass spectrometry.

There were few reports about antibiotic residues in egg-containing products. In the study, an effective method for the simultaneous determination of 24 sulfonamide antibiotics in two instant pastries based on a modified QuEChERS sample preparation technique coupled with ultra performance liquid chromatography-tandem mass spectrometry was developed. The results show that the average recoveries of the SAs at 5, 10, and 50 μg kg^-1 levels were 67.6%-103.8%, with relative standard deviations (RSD) of 0.80-9.23%. The limit of detections (LODs) and limit of quantitations (LOQs) were 0.01-0.14 μg kg^-1 and 0.02-0.45 μg kg^-1, respectively. This method was suitable for analysis of 24 SAs in instant pastries.
