Fate of zearalenone, deoxynivalenol and deoxynivalenol-3-glucoside during malting process
MetadataShow full item record
Malting was simulated using two different batches of barley as raw material: a naturally contaminated batch and laboratory inoculated (with a deoxynivalenol (DON) and zearalenone (ZEA) producing Fusarium graminearum strain) one. Up to three contamination levels were prepared, every process being carried out in triplicate. A significant washout effect on DON was observed by the end of the first water phase (between 22.4 and 34% reduction) with an even more pronounced reduction (up to 75% decrease) by the end of the steeping process. ZEA content remained almost unchanged (no significant difference between the initial and the final concentration). Germination was characterized by an increase in all the three toxins (ZEA, DON and DON-3-G) concentrations, however showing a decreasing trend in the last 24 h of the stage, compared to the first day of germination. Kilning lead to a significant reduction of DON in the naturally contaminated batch (46.6 and 78.8%), nevertheless an increase in all other toxins and contamination levels was observed.
