Abstract
Disclosed are methods for preparing dairy compositions using an ultrafiltration step and a nanofiltration step, followed by diafiltration of the nanofiltration retentate, and then at least one of a reverse osmosis and a forward osmosis step.
Claims24
A method for making a dairy composition, the method comprising:
- (a) ultrafiltering a milk product to produce a UF permeate fraction and a UF retentate fraction;
- (b) nanofiltering the UF permeate fraction to produce a NF permeate fraction and a NF retentate fraction;
- (c) diafiltering the NF retentate fraction to produce a DF/NF permeate fraction and a DF/NF retentate fraction;
- (d) subjecting the NF permeate fraction, the DF/NF permeate fraction, or a combination thereof, to a reverse osmosis step to produce a concentrated mineral fraction and a milk water fraction;
- and
- (e) combining at least two of the UF retentate fraction, the DF/NF retentate fraction, the concentrated mineral fraction, the milk water fraction, and a fat-rich fraction to form the dairy composition.
