Apparatus and process for the fractionation of liquid solutions of protein mixtures which includes the steps of subjecting such solutions to electrodialysis (ED) while in the pH range of about between 5-8 until a partial or a substantially complete desalting takes place, the ED preferably being conducted between about 15 DEG C. to 40 DEG C., separating the fraction of protein which precipitates, passing the resulting supernatant salt depleted protein mixture into the concentrating compartments of the ED apparatus whereby the salts entering the salt concentrating chambers from the adjacent salt diluting chambers will substantially restore the original salt content of the desalted protein mixture. |
