Optimization of combined subcritical water and CO2 extraction for enhanced phenolics and antioxidant activity from coffee byproducts

Optimization of combined subcritical water and CO2 extraction for enhanced phenolics and antioxidant activity from coffee byproducts

Abstract This study investigates the extraction of phenolic compounds and antioxidant activity from spent coffee ground (SCG) and coffee cherry pulp (CCP) using subcritical water extraction combined with high-pressure carbon dioxide (CO₂). The objective was to optimize extraction conditions to maxim...
