N2 - Betacyanins have gained increasing interest as natural food dye because of their health-promoting effects. This study investigated the betacyanins extraction from peel and flesh of red–purple pitaya using ethanol/K 2 HPO 4 -based liquid biphasic partitioning system (LBPS) by optimised concentrations of ethanol, K 2 HPO 4 , NaCl and crude. Overall, the highest values of betacyanins concentration in alcohol-rich top phase (C t ), phase volume ratio (V r ) and partition coefficient (K) of betacyanins that represented an optimum betacyanins extraction from the peel (98.080%, 1.667 and 51.097, respectively) and flesh (96.256%, 2.167 and 25.764, respectively) were achieved. Lastly, conventional solvent extractions, colour characterisation and antioxidant activity evaluation were conducted.
