Polymer materials are materials that are commonly used in the food industry for packaging. If a released into the environment, polymer materials pose a problem for the environment due to the long decomposition time. In order to solve the problem of polymer packaging, research is focused on the development of materials prepared from natural biopolymers that can be easily decomposed . Materials made from natural biopolymers and with the addition of active components such as polyphenolic compounds become active biopolymer materials. This work aimed to prepare and investigate an active material based on starch biopolymer with incorporated chokeberry (Aronia melanocarpa) polyphenols. Aronia polyphenols were obtained by ultrasound - assited extraction. Using reversed-phase high-performance liquid chromatography (RP-HPLC), they were identified as anthocyanins (cyanidin-3-galactoside, cyanidin-3-glucoside, cyanidin-3-arabinoside and cyanidin-3-xyloside), phenolic acids (neochlorogenic and chlorogenic acids) and flavonols. (quercetin-3-rutinoside, quercetin-3-galactoside and quercetin-3-glucoside). Their total amount was 1072 mg/kg. Aronia polyphenols were adsorbed on starch in a total amount of 2.2 or 1.6 mg/g of starch (for the two prepared materials starch-polyphenols 1 and starch-polyphenols 2). Anthocyanins (49.4%) and phenolic acids (47%) were adsorbed in the highest percentage, and flavonols (3.6%) in a smaller percentage. The amount of polyphenols adsorbed on starch increased as the concentration of polyphenols in the extract increased (\(r^{2}\) = 0.9895 to 0.995). A film was prepared from the starch with adsorbed chokeberry polyphenols and with the addition of a plasticizer. It can serve as an active packaging material.. The properties of the film and the possibility of food packaging need to be investigated further.
