Bioactive compounds from coffee husk (Coffea arabica) obtained by green extraction methods: Characterisation, antioxidant capacity and inhibition of lipid peroxidation.
Coffee husk, the principal by-product of wet coffee processing, is an underutilized agro-industrial residue with significant potential as a source of bioactive antioxidant compounds. In the present study, four green extraction methods were evaluated: aqueous extraction (AQU), ultrasound-assisted extraction (UAE), micro...
