Valorization of Spent Coffee Grounds: Comparing Phenolic Content and Antioxidant Activity in Solid-Liquid vs. Subcritical Water Extraction Methods

The aim of this work was to extract phenolic compounds (PCs) from spent coffee grounds (SCGs) using two different methods (solid-liquid extraction (SLE) and subcritical water extraction (SWE)) and compare their total phenolic content (TPC) and their antioxidant activity (AA) by 1,1-diphenyl-2 picryl...
