QuEChERS-超高效液相色谱-串联质谱法测定酥油中17种真菌毒素Determination of 17 mycotoxins in ghee by QuEChERS-ultra-high performance liquid chromatography-tandem mass spectrometry

QuEChERS-超高效液相色谱-串联质谱法测定酥油中17种真菌毒素Determination of 17 mycotoxins in ghee by QuEChERS-ultra-high performance liquid chromatography-tandem mass spectrometry

旨在为酥油中真菌毒素污染风险的监测与防控提供技术支撑，建立了QuEChERS技术结合超高效液相色谱-串联质谱法（UPLC-MS/MS）测定酥油中17种真菌毒素的检测方法。酥油样品经过3%甲酸水和3%甲酸乙腈溶液分步提取后，加入MgSO4和NaCl进行盐析处理，通过0 ℃低温离心和正己烷除脂，以N-丙基乙二胺（PSA）和十八烷基键合硅胶（C18）吸附剂作为净化填料净化后，经ACQUITY UPLC BEH C18色谱柱（100 mm × 2.1 mm，1.7 μm）实现分离，采用多反应监测（MRM）模式检测，基质匹配曲线外标法定量。结果表明：17种真菌毒素在相应质量浓度范围内呈良好的线性关系，决...
