Electron Beam Irradiation (EBI) was used to degrade zearalenone (ZEN) and deoxynivalenol (DON). The degradation effects of EBI on single and mixed toxins were investigated, and the regularities of degradation and interaction of toxins were analyzed. The results showed that the degradation rate of single toxin in standard solution increased with the increase of EBI dose in the range of 0-10 kGy, and low initial concentration of toxin contributed to high degradation rate. At 10 kGy, the degradation rates of ZEN and DON at 1 ìg/mL were 76.04% and 89.31%, respectively. Using single toxin group as control, with EBI treatment on DON and ZEN mixture, the degradation rates of ZEN in standard solution and corn syrup were significantly reduced, while DON degradation rates showed no obvious change. In addition, the degradation rates of ZEN and DON in the corn flour with 14.20% (w/w) moisture content were both lower than that of the control group. When the water content was 19.80% (w/w), the degradation rate of ZEN was lower than that of the control group and DON was higher than the control group. This study clarifies the effects of EBI on the simultaneous degradation of ZEN and DON in corn, which can provide a theoretical reference for the application of EBI in the degradation of food mycotoxins.
