DON toxin content examination of milling byproduct generated after colour sorting procedure in terms of nutritional utilization

Abstract

SUMMARY Thanks to the impact of vintage effect occurring in recent years the Fusarium contamination of wheat and consequently a high DON toxin concentration often cause problem. The DON toxin in terms of human and animal health is a serious food safety risk factor. Therefore, it is important to have methods during the wheat milling process, which reduce the level of toxin. The authors confirmed in earlier examinations, that using modern colour sorting machine the DON toxin content of wheat items can effectively be reduced. The question is, that how does the mycotoxin content of the resulting byproduct change, which is used primarily as animal feed. The authors presented an analysis of these relevant experimental data. The results show, that the toxin content of the by-product exceeds the starting wheat item's one. However, the result of the regression analysis shows that there is no correlation between the toxin contents of the starting raw material, the purified wheat and the by-product. This should be considered by the users when the resulting material is intended to utilize as feed ingredient
