Selective partition of caffeine from coffee bean and guarana seed extracts using alcohol-salt aqueous two-phase systems

This work proposes the application of flexible alcoholic aqueous two-phase systems to manipulate the partition of caffeine. An optimization study was performed the caffeine partitioning towards top phase (60.0 wt% 2-propanol + 20.0 wt% K3PO4 at 303 K - K-caf = 3.4 and R-T = 89.1%) and bottom phase (...
