Cover Story: In this work, the recovery of phenolic compounds from apricot and peach waste is optimized through ultrasound- and microwave-assisted extraction (UMAE), while changing the used solvents and the process parameters of extraction time, ultrasonic power and solvent/dry solid ratio. Prior to extraction, freeze, vacuum and hot air drying are conducted. Except for the conventional solvents of water and ethanol: water, deep eutectic solvents (DES) formed by choline chloride/urea and natural deep eutectic solvents (NaDES) from choline chloride: lactic acid are used, leading to ecological benefits. The phenolic compounds and the antioxidant activity are determined through UV–Vis spectroscopy and HPLC and a mathematical model is developed to correlate the extraction parameters to the extraction yield.
