Life of this patent

Estimating the term…

Disclosed are methods for preparing dairy compositions using an ultrafiltration step, a nanofiltration step, and a forward osmosis step.

Dependent claims

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) subjecting the NF permeate fraction to a forward osmosis step to produce a mineral concentrate;
and
(iv) combining at least two of the UF retentate fraction, the mineral concentrate, water, and a fat-rich fraction to form the dairy composition.
