The use of a 96-well electrochemical plate for the fast and sensitive detection of deoxynivalenol and nivalenol in wheat samples is shown. Deoxynivalenol and nivalenol are hydrolysed using a microwave hydrolysis procedure (2 min) which leads to the production of electroactive compounds that can be sensitively detected by the use of cheap screen-printed electrodes. A procedure of extraction with aqueous acetonitrile and a clean-up step was demonstrated to be suitable for the application with wheat samples providing suitable detection limit (LOD=1.1 µg/g) and working range (2-20 µg/g) for the determination of deoxynivalenol in cereals for feed consumption.
