Resveratrol antimycotoxigenic activity was tested against Fusarium verticillioidesand Fusarium graminearum in corn. Both trans-resveratrol and RES VIN® (a commercial lyophilised polyphenolic product obtained from the skins of red wine grapes, which contains a 10.015% resveratrol) were tested for their efficacy to control mycotoxins accumulation in corn. In particular, their effects were tested against fumonisin B1(FB1) and zearalenone (ZEA) accumulation in naturally contaminated corn with additional inocula of toxinogenic isolates of either F. verticillioides or F. graminearum. ZEA accumulation was reduced by 80% in F. graminearum inoculated samples, while no inhibition of FB1 accumulation was observed in any of the treatments tested. Resveratrol has previously shown to have antifungal properties against certain fungal species. Thus, studies are needed using higher resveratrol concentrations in order to achieve wider antimycotoxigenic effect as reported in in vitro studies. Trans-resveratrol and RES VIN® had similar effects in the experiment carried out, suggesting that the use of the sub product of the wine industry could be a good alternative to synthetic resveratrol.
