The effect of low-temperature plasma discharge on mycotoxin content in barley and malt

Popis výsledku v původním jazyce

Contamination of malting barley by mycotoxins affects their presence in malt and in the resulting product - beer. Therefore, methods are being developed to eliminate or reduce their concentration. This work deals with the possibility of elimination of common occurring mycotoxins deoxynivalenol (DON) and its plant metabolite deoxynivalenol-3-glucoside (D3G) from malting barley and malt using low-temperature plasma discharge of Gliding Arc type. Samples of harvested barley were plasma-treated and analyzed for the presence of mycotoxins. Only low levels of DON and D3G were detected (maximum values were 48.2 mu g/kg and 30.2 mu g/kg for DON and D3G, respectively). After treatment of plasma discharge, mycotoxin levels decreased to levels near the limit of quantification. The results indicate that the low-temperature plasma discharge of Gliding Arc type may contribute to the reduction of mycotoxin content in harvested barley grains. Due to low concentrations, the effect of plasma treatment in malt was not confirmed.
