A screening method for mycotoxin analysis in cereal products and spices was developed and validated using UHPLC-MS/MS, with d-SPEs used for sample extraction. Various mycotoxins were validated in maize and black pepper, meeting the requirements of EC regulations. The method's performance was evaluated through proficiency assessment and testing with 100 real samples.
We developed and validated a screening method for mycotoxin analysis in cereal products and spices. Ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) was used for the analysis. Dispersive solid-phase extractions (d-SPEs) were used for the extraction of samples. Ochratoxin A (OTA), zearalenone (ZEA), aflatoxins (AFLA; AFB(1), AFB(2), AFG(1), AFG(2)), deoxynivalenol (DON), fumonisin (FUMO; FB1, FB2, FB3), T2, and HT2 were validated in maize. AFLA and DON were validated in black pepper. The method satisfies the requirements of Commission Regulation (EC) no. 401/2006 and (EC) no. 1881/2006. The screening target concentration (STC) was under maximum permitted levels (MLs) for all mycotoxins validated. The method's performance was assessed by two different proficiencies and tested with 100 real samples.
