Abstract:
1. A process for at least one of the isolation or purification of 3′-sialyl lactose, 6′-sialyl lactose, anionic oligosaccharides from whey, the process comprising the steps of: contacting the whey with at least one group of ion exchange resins, the group comprising a first weak acid cation resin, a first weak base anion resin, a second strong acid cation resin and a second weak base anion resin to produce a demineralized whey; contacting the demineralised whey with two further ion exchange resins comprising a third strong acid cation resin followed by a weak base anion resin wherein the 3′-sialyl lactose, 6′-sialyl lactose, anionic oligosaccharides and/or proteins is taken up on the weak base anion resin; and eluting the 3′-sialyl lactose, 6′-sialyl lactose, anionic oligosaccharides and/or proteins from the weak base anion resin.
