Detection method for determining mycotoxin in cereal grains by combining QuEChERS pretreatment with LC-MS/MS

The invention belongs to the field of food safety detection, and discloses a detection method for determining fungaltoxin in cereal grains by combining QuEChERS sample pretreatment with LC-MS/MS. Specifically, the cereal grains are subjected to extraction and QuEChERS purification and then are inspected and detected by a liquid chromatography-mass spectrometer, the anti-interference ability to complex matrixes is high, the method sensitivity is high, the accuracy and the repeatability are good, and the method can be widely applied to the field of food safety detection. The pretreatment is more convenient. 本发明属于食品安全检测领域，本发明公开了QuEChERS样品前处理结合LC-MS/MS测定粮谷中的真菌毒素的检测方法，具体是粮谷经过提取和QuEChERS净化后，用液相色谱质谱仪检验检测，对于复杂基质的抗干扰能力强，方法灵敏度高，准确性和重复性好，前处理更便捷的检测方法。
