Determination of multiple mycotoxins in chili powder using cold-induced liquid–liquid extraction and Fe3O4@MWCNTs-NH2 coupled with UPLC-Q-TOF/MS

•An effective method for simultaneous analysis of multiple mycotoxins was established.•Cold-induced phase separation of aqueous-acetonitrile solution effectively eliminates matrix interference.•Fe3O4@MWCNTs-NH2 simplified the sample pre-treatment and allowed rapid separation.•Good accuracy and precision and low LOD were achieved for ten mycotoxin determinations.•It can be used for the simultaneous detection of multitype mycotoxins in complex food matrices at trace levels.
