Supramolecular solvent extraction of bioactives from coffee cherry pulp

The potential of supramolecular solvents (SUPRAS) is investigated for the extraction of bioactive compounds from coffee cherry pulp, one of the major by-products generated in the coffee industry. SUPRAS made up of hexagonal inverted aggregates of octanoic acid in ethanol:water mixtures provided good extraction yields for bioactives (3.6 ± 0.3 mg caffeine g−1 and 0.9 ± 0.1 mg protocatechuic acid g−1) at a low solvent:sample ratio of 4:1 v/w and...
