The determination of trichothecene mycotoxins, which do not absorb in the UV range by using the HPLC method, is possible after the A Simple Method for Determination of Deoxynivalenol in Cereals and Flours FILIP KOTAL and ZUZANA RADOVÁ Department of Food Chemistry and Analysis, Institute of Chemical Technology, Prague, Czech Republic Abstract KOTAL F., RADOVÁ Z. (2002): A simple
A simple method for determination of deoxynivalenol (DON) in cereal samples is described. DON was extracted with methanol, the solvent evaporated, and the residue redissolved with water. This extract was purified on immunoaffinity columns. DON was determined by HPLC with UV-detection. The limits of detection (LOD) and quantification (LOQ) were
A reliable quantitative method for the rapid and simultaneous determination of 16 mycotoxins commonly found in major cereal species has been established using an Agilent Triple Quadrupole LC/MS system. This method can meet the requirements for high-throughput and rapid monitoring of multiple mycotoxins commonly found in cereals. Experimental
Determination of deoxynivalenol in cereals and cereal products by immunoaffinity column cleanup with liquid chromatography: Interlaboratory study
Near Infrared (NIR) spectroscopy has been used routinely during many years at elevators and mills for determination of protein and moisture in cereals. The technique is rapid taking just a few minutes and has the potential for determination of other compounds. The concentrations of mycotoxins normally found are, however, considered low for this
