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.
Claims22
1-43. (canceled)
A method for making a dairy composition, the method comprising:
- (i) ultrafiltering a milk product to produce a UF permeate fraction and a UF retentate fraction;
- (ii) nanofiltering the UF permeate fraction to produce a NF permeate fraction and a NF retentate fraction;
- (iii) diafiltering the NF retentate fraction to produce a DF/NF permeate fraction and a DF/NF retentate fraction;
- (iv) subjecting the NF permeate fraction, the DF/NF permeate fraction, or a combination thereof, to a forward osmosis step to produce a mineral concentrate and a milk water fraction;
- and
- (v) combining at least the UF retentate fraction and the mineral concentrate, or at least the UF retentate fraction, the mineral concentrate, and a fat-rich fraction, to form the dairy composition.
