A method for the simultaneous determination of FB1 and its major hydrolysis product HFB1 after extrraction of samples with acetonitrilemethanol-water (25:25:50) and solid-phase C18 cleanup. The detection limits were 8 mg/kg for HFB1 and 5 mg/kg for FB1 using the protonated molecule signals m/z 406 and 722 in the SIM mode. Analysis of several corn containing foodstuffs, among them extrusion products and alkali processed corn food such as tortilla chips, showed HFB1 and FB1 contamination levels of 8 – 80 and 5-450 mg/kg respectively.
