In 2010-2011 in Norway was carried out laboratory and field research of oats seeds (Belinda breed) and spring wheat (Zebra breed) that were separated on CAD machine.

Experiments were carried out by Dag Saether together with consulting department of agriculture in Romerike Felleskjøpet Agri.

Researches were carried out on two fields with different levels of infection with the fungus Fusarium graminearum (fields were infected artificially).

After separation on CAD machine samples from the field with higher level of infection showed significant decrease in the level of mycotoxins.

Percentage of germination increased from 40% in initial material to 80% in first fraction (see diagram).

where F1 – F5 – fractions that were got after separation of the initial material;

F2B – second fraction after re-separation.

This is due to the fact that grain with the lowest weight is most infected with fungus Fusarium graminearum. Due to the removal of seeds with very high values of deoxynivalenol the quality of batch can be significantly improved (see Table).

Note: Mycotoxins (from Greek words „mukos“ — fungus and „toxicum“ — poison) is a toxic secondary metabolite produced by organisms of the fungus kingdom, commonly known as molds. Mycotoxins are natural contaminants of cereal grain, beans, sunflower seeds. Due to the impact of mycotoxins animals and human get poisoning – mycotoxicosis. The presence of mycotoxins in food and feed leads to deterioration in productivity, reproduction and the IMMUNEstate of human and animals.

Mould fungus Fusarium graminearum produces mycotoxin – Deoxynivalenol and its main toxic effect is – neurotoxin.

The resulting research findings are published in the authoritative periodical magazine „Norwegian agriculture“.
