Consequences of the presence of toxicogenic mold fungi in grain

Goal. To study how the content of fusarium grains and products vital activity Fusarium fungus in wheat changes during its storage. establish within what limits number mycotoxins grown Vinnytsia region varies. Methods. Grains with signs were identified samples isolated from average using a magnifying glass (magnification 4.5 times) microscope MBS type 100–150 under sufficient lighting. The presence was determined by immunoenzymatic method, which involved use test systems Sunrise analyzer. Results. Among grain examined 2019, 45.2% affected fungus, 71.4% those 2020, 87.5% 2021. That is, there is tendency to increase amount fungi genus Fusarium. But if 2019 share up 11%, 2020 — 18, then 2021 maximum damage 8.1%. are various factors influencing spread these mushrooms, they must be studied. It established that storage wheat, contained 0.7% grain, infection increased confirmed index waste admixture. In such mass fraction protein decreased increased. Thus, deoxynivalenone can 2.92 mg/kg, i.e. 2.6 times, significantly exceeds permissible level (1–2 mg/kg) fodder grain. conducted studies, it put into 0.5% 3-4 zearalenone 7.3, T2 toxin 30 times. Conclusions. Over past three years, observed an contamination crops wilt and, as result, it. after 3 months, may contain 3.51 mg/kg deoxynivalenone, zearalenone, 0.6 toxin. should remembered already contains will accumulate them future, therefore, control for fungal by-products mandatory.
