A novel method for the simultaneous determination of the trichothecene mycotoxins deoxynivalenol(DON), nivalenol (NIV), 3-acetyl-deoxynivalenol (3-ADON), and 15-acetyl-deoxynivalenol (15-ADON)in barley and malt extracts has been developed using Matrix Assisted Laser Desorption Ionization Timeof Flight Mass Spectrometry (MALDI TOF MS). This technique enables highly sensitive and fastanalysis and/or detection using very small samples. In this work several matrices were examined and themost suitable ones were identified. Statistical analysis was carried out to verify the ability of the systemto determine the mycotoxins in a real sample. Test for the accuracy of the method, repeatability, limit ofdetection (LOD) and limit of quantification (LOQ) were studied. Moreover, the accuracy of the methodwas confirmed by comparing analytical data to certified values from reference materials for thosemycotoxins. In addition, a comparison of the analytical parameters for the determination of DON, 3-ADON, 15-ADON, and Nivalenol was carried out. This work opens up the possibility of very sensitivedetermination of the selected mycotoxins in barley, malt, cereals and food. |
