Abstract

The content of arabinoxylans (AX) in meal and flour fractions of modern winter triticale varieties was evaluated, and the content of total arabinoxylans, water-soluble arabinoxylans (WSAX), and water extract viscosity (WWE) in triticale was analyzed in comparison with other cereals, including winter soft wheat, spring soft wheat, spring durum wheat, and winter rye. The meanWSAX in winter triticale varieties was 0.90%, with moderate inter-variety differences. The average WSAX content was found to be three times higher in triticale varieties than in winter wheat, 3.6 times higher than in spring soft wheat, and 4.5 times higher than in spring durum wheat, which cultivated under the same environmental conditions. Significant variability in content AXand WWE was observed between genotypes of winter triticale, as well as between triticale and its parental species. It was found that modern triticale varieties exhibit an AX and viscosity profile that is significantly more similar to wheat than to rye. AX content of the studied winter triticale varieties occupies an intermediate position in relation to wheat and rye, with notable inter-variety differences. The results obtained can be utilized in the production of nutritional fodder and in fodder production and livestock production.
