Resumo: The objective of this work was to optimize the derivatization reaction for determining deoxynivalenol (DON) by gas chromatography employing an experimental planning procedure. The factors were: temperature, reaction time, catalyst and trifluoroacetic anhydride concentration. The relative peak areas were used to evaluated the effects. The best conditions for DON derivatization were 200 μL TFAA and 18 mg sodium bicarbonate for 6 min at 74 °C for 7 to 21 μg of DON. Under these conditions, the detection limit was 1.4 μg of DON.
