Mycotoxicosis caused by Fusarium fungi holds a huge risk considering economic and food safety issues worldwide. By applying milling technologies, we attempted to reduce the concentrates of DON toxin, as it is the most often found toxin in wheat. The processes of sieving, aspiration and combination had been used on wheat with high DON toxin concen...tration. As a next step, grains were sorted using a horizontal cylinder separator, assorted by an optical and a gravity separator, and finally, the products were scoured and ground. The contamination level of the wheat and flour samples were defined by the HPLC-MS method. Regarding the results, it can be stated that toxin concentration was most effectively reduced by optical separation and scouring, and by applying these milling techniques, food safety can be increased significantly.

The fungi causing the infection and most of the harmful toxins they produce are concentrated in the bran of the grain, thus the intensive surface cleaning, the so-called debranning operation could allow the reduction of contamination in the milling technology. The essence of the PeriTec technology – originally developed by SATAKE, a Japanese com...pany, to clean rice – is that it gradually removes the bran layers of the grain by mechanical means before further processing. We modeled the PeriTec technology with a laboratory size, batch-operating, horizontal debranning machine by SATAKE. The flour, milled grain after grinding 40 sec, the initial toxin content was only a small proportion (~15–20%) measured. The results showed that below the limit of DON toxin contaminated wheat (DON: 1.15 mg kg-1) during the grinding surface of the detached bran toxin contamination shows a very high (6.16 mg kg-1). The 40 seconds debranning before grinding shows lower DON toxin content than without debranning. So it is importance before the grinding. The toxin contamination of the bran fractions is significantly reduced, which is importance to the feeding point.  As a result of debranning, the toxin content of the grinding fractions decreased, which justifies that that PeriTec method is suitable for the reduction of toxin contamination.
