Abstract
Orange peel (OP) is a relevant by-product of the citrus industry, rich in phenolic compounds and ascorbic acid (AA), but its sustainable valorization requires green and efficient extraction strategies. In this study, six natural deep eutectic solvents (NADES) selected via COSMOTherm solubility modelling were evaluated for the recovery of bioactive compounds from OP using ultrasound-assisted extraction (UAE) followed by a stirring treatment.
Overall, the study demonstrates that tailored NADES–UAE combinations constitute an effective and sustainable approach for recovering high-value antioxidants from orange peel, contributing to circular economy strategies and green extraction technologies.
