In the applications of whey powder, the minerals can interfere with the taste. The production of demineralized whey powder proceeds via ion exchange or, preferentially, electrodialysis (1.5-4.5V/cell current density 5-20mA/cm membrane area. Fig. 10.31). The course of demineralization is shown in Fig. 10.32. 

Demineralization of UF whey retentate as compared to UF whey permeate is generally slowed down by salt and/or proteins that build up onto and in the membranes (Perez et al., 1994). Finally, in the case of skim milk the aim of the ED process is not only to reduce the overall ash content, but also to increase the calcium/phosphate ratio to about 0.77 in skim milk powder used in infant formula (Batchelder, 1987), this goal being much easily achievable by replacing the conventional membranes with selective ones (Andres et al., 1995).
