Abstract

Fumonisins a type of mycotoxins produced by Fusarium species can cause fatal diseases in animals and humans Therefore regulatory limits for food and feed were established in many countries Herein a sensitive valid costeffective and easily transferable analytical method for quantitative determination of the relevant fumonisins B1 FB1 and B2 FB2 in corn and corn products was developed The final method is based on reversedphase highperformance liquid chromatography with fluorescence detection RPHPLCFLD Derivatization of analytes was simplified by establishing an automated precolumn derivatization method by using an autosampler Strong anion exchange SAX cartridges were used instead of widespread immunoaffinity chromatography IAC approaches Analytes and matrix signals were chromatographically separated in a total run time of 25 min by means of a C8 column and a gradient elution using methanol and phosphate buffer The limits of detection LODs for FB1 and FB2 were 292 and 175 μg/kg respectively Obtained recoveries ranged from 794 to 945  for FB1 and from 799 to 980  for FB2 Positive confirmation of the developed method was achieved by participating in an interlaboratory proficiency testing Nineteen samples of sweet corn and corn products were analyzed to demonstrate the applicability of the methodFlorian Kaltner declares that he has no conflict of interest Corina Rampl declares that she has no conflict of interest Michael Rychlik declares that he has no conflict of interest Thomas Zimmermann declares that he has no conflict of interest Alexander Rohe declares that he has no conflict of interest
