Abstract
The article investigates fructose biopolymers contained in the roots of Heliánthus annuus. The raw material has been analyzed in terms of the content of inulin and other accompanying components, which are both advantageous for developing new functional food products and challenging for inulin extracting. Because in the composition of preparations from the sunflower root, this may be an advantage for the future food product, but when extracting inulin, this can create certain difficulties. These components are polyphenolic substances, namely tannins. Literature sources describe the presence of polyphenols in conflicting amounts, which justifies our research objective. The article presents a study of the yield of inulin in the extract at different extraction temperatures. We have determined the moisture content of the crushed sunflower root, the content of extractives in percent in absolutely dry raw materials, the content of tannins in percent in absolutely dry raw materials, as well as the content of inulin. The research aims to apply the results obtained for the further development of a functional food product.
