Phospholipases comprise a group of enzymes with applications in the thermal stability and emulsifying capacity of food formulations. In this work aqueous two-phase systems (ATPS) were used to extract phospholipase A2 (PLA2) from raw porcine pancreas and snake venom at 25 °C. PLA2 was partitioned into ATPS composed of inorganic salts, water and polyethylene glycol. We determined the partition coefficient, recove...
