Cover Story: The authors sought to establish a novel methodology for the efficient recovery of polyphenolic antioxidants from coffee processing residues, namely coffee silverskin (CSS). The process developed is an ethanol-based organosolv treatment alongside acid catalysis using sulfuric acid or oxalic acid. It is proposed that this methodology may contribute towards the use of coffee processing wastes as potential sources of bioactive ingredients and the design of novel functional products, with the goal of coffee processing companies employing a more sustainable strategy. View this paper
