Minim Química PEG lactalbumin lactoglobulin Partition coefficients aqueous two phase systems In this work had been analyzed the partition coefficients (K) of a-lactalbumin (a-la) and b-lactoglobulin (b-lg) inAqueous Two Phase Systems (ATPS) formed by polyethylene glycol (PEG) + potassium phosphate (FFP) + water, in pH 7and 25°C. The ATPS preselected was formed by PEG of molecular mass (MM) 1500 Daltons, with concentrations 14% PEG-14% FFP, 16% PEG -14% FFP, 16% PEG -16% FFP, 18% PEG -14% FFP, 18% PEG -18% FFP. The system with 18% (w/w) PEG1500 -18% (w/w) FFP showed the higher K for a-la and the lower k for b-lg, being the more efficient separation ATPS in ourcase. In this composition was investigated the influence of several molecular mass of PEG on k. The increase of the PEGmolecular mass raised the concentration of a-la in the salt bottom phase, decreasing K. For b-lg was observed an inversebehavior of K on the increase of the PEG MM, except for PEG 8000 Daltons. © 2001 Altaga.
