Changes in the content of various Fusarium mycotoxins forms in germinating winter wheat and spring barley kernels

Abstract

Fusarium mycotoxins are frequent contaminants in cereals at temperate zone. Next to deoxynivalenol (DON), there are other masked forms of DON, deoxynivalenol-3-glucoside (D3G) or 3(15)-acetyl-deoxynivalenol (3(15)-ADON), but changes among these forms are still insufficiently known. All these forms were evaluated in germinating kernels of wheat and malting barley from deliberated inoculated field plots. Results showed possible occurrence of high ini tial content of all evaluated DON forms. Total contents of all forms were detected as very steady from start to end of the germination process. It suggests high importance of evaluating not only DON content, but all DON forms simultaneously.
