The fungi causing the infection and mycotoxins production 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 company, to clean rice - is that it gradually removes the bran layers of the grain by mechanical means before further processing. We carried out our experiments using a naturally contaminated wheat lot. We modelled the PeriTec technology with a laboratory size, batch-operating, horizontal debranning machine by SATAKE. Applying different treatment times we varied the rate of debranning. As for DON (deoxinivalenol) toxin contamination, a continuous decrease can be found by increasing the rate of debranning. The total Hour obtained during grinding the unpolished wheat contains 0.25 mg/kg toxin on average, which decreases to 0.11 mg/kg if we apply the highest, 40 sec polishing. Figure 4 shows the DON toxin content of all the obtained fractions. The toxin contamination of the wheat grains and the grinding fractions gradually decreased as a result of debranning. Very high toxin content of the removed parts of the husk indicates that toxin is concentrated in the outer husk layers. Although the DON content of the original wheat sample was relatively law (0.74 mg/kg), the DON content of the removed materials wa s about 4 mg/kg, which exceeds all statutory limits. During our work we focused mainly on the toxin contamination of the grains and their milling products, as well as on other characteristics that are important with regard to milling processing. 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. On the basis of the experimental results, the optimum peeling was the peeling which resulted in a weight loss of about 6%. the toxin content significantly decreased (from 1,59 mg/kg to 0,94 mg/kg).
