o:7991 DEVELOPMENT OF ANTHOCYANIN-LOADED ELECTROSPUN NANOFIBERS: NEW HORIZON FOR THE VALORIZATION OF CHOKEBERRY FRUIT WASTE en Recovering bioactive components from the chokeberry waste in the fruitprocessing industry has attracted great attention in terms of minimizing the waste burden and providing a new source of valuable functional compounds. To develop new functional nanomaterials, ultrasound-assisted extraction was combined with electrospinning technology. The optimal conditions for maximizing the extraction of individual and total compounds were 45% ethanol concentration at 60 °C. By varying ratio of PVP, HP-β-CD, and HP-γ-CD four electrospun nanofibers loaded with the chokeberry waste extract were prepared. They were characterized with notable concentrations of cyanidin galactoside, glucoside, and arabinoside derivatives, and strong antioxidant potential. The FT-IR analysis confirmed conjugation between the carriers and bioactives, while the PAMPA assay suggested that anthocyanins likely cross the stomach cell membranes via active transport. Converting food waste into specifically tailored formulation holds a great potential to contribute to the consumers’ nutrient and health benefits, while creating opportunities for integration into new value-added products. 2025-07-21T10:32:47.506Z 44 no 46 Milica Radan Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-6727-7624 46 Anna Stasiłowicz-Krzemień Dpt of Pharmacognosy and Biomaterials, Fac.
