Conteúdo: 	Acai, a fruit typical of Amazonia in Brazil, is consumed due to beneficial health effects. Aqueous two-phase systems (ATPS) based on ethanol (28% w/w) and ammonium sulfate (17.5% w/w) were employed in the partitioning of anthocyanins from acai. Experiments, applying 50 mL equilibrium cells and a 1-L glass vessel reactor, evaluated anthocyanin partition feasibility on a laboratory scale-up. The anthocyanin preferentially moved to the top (ethanol-rich phase) and sugars to the bottom (ammonium sulfate-rich phase). Scale-up effects were compared with the equilibrium cell experiments with anthocyanin extraction yielding more than 64% w/w, the yield of sugars in the bottom phase (>61% w/w) and removal of sugars (97%), showing the feasibility for the scale-up process. The anthocyanin profile from acai, ATPS partition on the bench scale and laboratory scale-up evaluated by UPLC-QTOF-MS identified cyanidin, peonidin and pelargonidin derivatives.
