For the detection of new glucoside derivatives of mycotooxins (masked mycotoxins), screening based on the accurate mass was carried out through the high resolution mass spectrometry measurement with LC-MS (LC-Orbitrap MS). Consequently, mono-glucoside derivatives of type B trichothecenes (nivalenol and fusarenon-X) in wheat grains infected with Fusarium strains and those of the type A trichothecenes (T-2 toxin, HT-2 toxin, neosolaniol, diacetoxyscirpenol, and monoacetoxyscirpenol) in corn powder reference material were detected, respectively. Di-glucoside derivatives were also found for T-2 toxin and HT-2 toxin. These findings indicate that the presence of masked mycotoxins is not limited to some specific mycotoxins such as deoxynivalenol and zearalenone, but likely with the other Fusarium mycotoxins.
