Abstract

This review aims to highlight current emerging technologies for the valorization of the bioactive fraction of waste from cherry and grape processing industries through its recovery and conversion into high added-value products. Due to its richness in diverse functional and health-related metabolites, the valorization of cherry residue and grape residue as a source of bioactive compounds for new food, nutraceutical, and pharmaceutical products has great interest and potential. Furthermore, aiming for more sustainable processes, several process intensification technologies (UAE, SWE, MAE, PEF, ASE, and NaDES) have emerged in recent decades to extract bioactive compounds from these byproducts, according to a circular economy approach. These techniques allow a considerable reduction in extraction time, greater mass transfer, lower energy consumption, volume of solvents, and energy. Consequently, these new technologies have potential for application on a pilot scale.
