Recovery of the proteose peptone component 3 from cheese whey was optimal using a 16% (w/w) Reppal PES 100 – 24% (w/w) PEG 600 aqueous two-phase system, at pH 7, giving a mass recovery yield of 99% and a purity of 83% for proteose peptone component 3 in the upper phase. Using the above system a partition coefficient of 30.7 and a purification factor of 6.9 were achieved
