Deoxynivalenol (DON) is a secondary metabolite commonly found in grains, which can lead to many adverse health effects to human and livestock. The degradation effects of electrochemical oxidation (EO) on pure DON and in wet distillers′ grains with soluble(WDGS)broth were investigated. The results showed that 76.4% of DON degraded within 60 min at a voltage of 1.2 V, and the degradation process could be expressed by first-order kinetics when the optimum NaCl concentration was 0.2 mol/L. In addition, the degradation rate of DON in contaminated WDGS was 43.28% after 60 min of treatment. Addition of electrolyte was favorable for the degradation. The crude protein and lipid content in WDGS did not change significantly before and after electrolysis. The electrochemical oxidation process can be used as an effective method for removing DON from WDGS in the corn fermentation industry.
