Whey Protein Fractionation by Membrane Technology

Whey protein contains, α lactalbumin, β lactoglobulin, Bovine serum albumin (BSA), immunoglobulins, lactoferrin that all are useful as a medicin .From this study Membrane separation technology involved UF in continuous diafiltration mode and NF for separation using different material of membrane gives more pure product at pH effect. Retentant yield for α lactalbumin ranged form 43% at pH 4,while for β lactoglobulin,was form 67% at pH 3.In contrast, and BSA(Bovine serum albumin), immunoglobulins and lactoferrin were mostly retained ,with improvement up to 60% in purity at pH9 with respect to original whey.
