Reasons of contamination of production lots of sunflower (Helianthus annuus L.) seeds by mycotoxins

In recent years, in our country there has been a clear trend towards sustainable growth in the production of sunflower oil. During long-term monitoring high risks of contamination with mycotoxins are established for the by-products of oil and oil-extracting industries, oil cakes and meals, which are traditionally in demand as valuable raw materials for mixed fodders (G.P. Kononenko et al., 2018). Among the possible reasons of contamination are the violations of the technology of production and storage of the final products, but the problem of the sanitary quality of oil seeds coming from the farms remains without attention. The purpose of our work was to survey the lots destined for the production of oil by comparing the contamination with mycotoxins of the main seeds and typical accompanying impurities. The average samples of sunflower oil seeds from the farms of the Belgorod, Voronezh, Kursk and Lipetsk regions of the 2016 year crop were fractionated into seeds and impurities (according to GOST 22391-2015) for separate study of their contamination...
