From Waste to Worth: Transforming Winemaking Residues into High-Value Ingredients.

Abstract

The wine industry generates significant amounts of waste, including vine shoots, grape pomace, and seeds. Traditionally regarded as waste, these materials are now recognized for their richness in bioactive compounds such as polyphenols, dietary fibers, and antioxidants, offering numerous health and environmental benefits. This review explores the potential applications of vinification residues and vine cultivation residues in the food, pharmaceutical, and cosmetic industries, highlighting recent advancements in these fields. The valorization of these winemaking wastes shifts toward a circular and sustainable economy, reducing environmental impact while creating economic opportunities. The need for optimizing waste management practices in the wine sector to foster sustainability and innovation is evidenced by the numerous patents filed in recent years. Future research should focus on scalable technologies, regulatory harmonization, and interdisciplinary approaches to fully integrate winemaking waste into high-value production chains.
