Abstract
Methods for preparing dairy compositions utilize an electrodialysis apparatus to separate a feed stream into a lactose stream and a mineral stream. The feed stream can be a UF permeate fraction, a NF retentate fraction, or a RO retentate fraction. The brine input to the electrodialysis apparatus can be a milk mineral stream.

1-37. (canceled)
A method for making a dairy composition, the method comprising:
- (a) ultrafiltering a skim milk product to produce a UF permeate fraction and a UF retentate fraction;
- (b) nanofiltering a first portion of the UF permeate fraction to produce a NF retentate fraction and a NF permeate fraction;
- (c1) introducing a second portion of the UF permeate fraction to a feed input of an electrodialysis apparatus;
- (c2) introducing water or a milk mineral stream to a brine input of the electrodialysis apparatus;
- (d) discharging from the electrodialysis apparatus a lactose stream and a mineral-enriched stream;
- (e) subjecting the NF permeate fraction or the mineral-enriched stream and the NF permeate fraction to reverse osmosis to produce a RO retentate fraction and a RO permeate fraction;
- and
- (f) combining at least the UF retentate fraction and the RO retentate fraction and/or the mineral-enriched stream to form the dairy composition.
