QuEChERS-LC-QTOFMS for the simultaneous determination of legislated and emerging mycotoxins in malted barley and beer using matrix-matched calibration as a solution to the commercial unavailability of internal standards for some mycotoxins
2021
Abstract The combination of QuEChERS-LC-QTOFMS and matrix-matched calibration (MMC) to simultaneously determinate legislated and emerging mycotoxins in malt and beer was evaluated for the first time. The method performance was satisfactory displaying suitable linearity (R2>0.99) and recovery (71-102%). The lowest values (in μg kg-1) of LOD (0.01) and LOQ (0.05) were found for enniatins, while the highest LOD (15) and LOQ (50) were reported for fumonisin B1. Precision and sensitivity (RSD
