Abstract: | This study evaluated the partitioning of ovomucoid from egg white, in aqueous two-phase systems (ATPS) composed of PEG 1500 and inorganic salt (lithium sulfate, sodium sulfate, magnesium sulfate, sodium carbonate or sodium citrate) at 25 °C. The results showed a great effect of the electrolyte nature on the partition coefficient. The partition coefficient value ranges from 0.02 to 6.0. The highest partition coefficients were obtained from systems composed of sodium carbonate and the lowest in systems composed of magnesium sulfate. In the system containing magnesium sulfate, a recovery percentage greater than 90% was obtained. |
