Resumo(s)

Grape by-products, such as skins and seeds generated during winemaking, represent a valuable source of bioactive compounds and dietary fiber. These residues are rich in phenolics—particularly anthocyanins—with recognized antioxidant, antimicrobial, and anti-inflammatory activities. Their valorization aligns with circular economy principles, promoting waste reduction and the development of sustainable ingredients. The exploitation of these materials for food, nutraceutical, and packaging applications provides an opportunity to replace synthetic additives with natural alternatives. The main objective of this work was to characterize and valorize grape by-products as natural sources of bioactive compounds and antioxidants for sustainable industrial applications. The NOVAPACK Project aims to integrate grape by-products into sustainable value chains through their physicochemical characterization and the extraction of bioactive compounds.
