Non-starch polysaccharides (β-glycans and arabinoxylans) of fifteen new and two commercially cultivated naked oat cultivars, as well as one hulled oat cultivar were studied.A strong correlation and ratio between the content of arabinoxylans and that of β-glucans have been determined. Cultivars with an increased content of these components have been selected. The studied cultivars demonstrated 11 electrophoretic banding patterns differing in α- and β-avenin fractions. In most naked oat cultivars were revealed several weak bands of α-avenin that are the most celiac-toxic peptides. It seems to be promising to assess toxicity of these cultivars from their reaction with celiac patients’ sera. The performed research is of immediate interest from the point of view of engineering functional and special purpose foods.
