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 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 and 0.02-0.45 μg kg, respectively. This method was suitable for analysis of 24 SAs in instant pastries.
关于含蛋制品中的抗生素残留的报道较少。本研究采用改进的 QuEChERS 样品前处理技术结合超高效液相色谱-串联质谱法，建立了同时测定两种速食糕点中 24 种磺胺类抗生素的方法。结果表明，在 5、10 和 50μg/kg 加标水平下，磺胺类抗生素的平均回收率为 67.6%-103.8%，相对标准偏差（RSD）为 0.80-9.23%。检出限（LOD）和定量限（LOQ）分别为 0.01-0.14μg/kg 和 0.02-0.45μg/kg。该方法适用于速食糕点中 24 种磺胺类抗生素的分析。
