Abstract
A process for demineralization of whey-based material using electrodialysis. The process involves increasing the conductivity of the diluting stream, i.e, the stream containing the material to be demineralized, at one or more points in time during the electrodialysis cycle. When removal of divalent ions is desired, the increased conductivity may occur by the addition of salts of monovalent ions.
