Claims5
A method for making a dairy composition comprising the steps of:
- subjecting milk to an ultrafiltration step to produce an ultrafiltration permeate fraction and a ultrafiltration retentate fraction;
- subjecting the ultrafiltration permeate fraction to a nanofiltration step to produce a nanofiltration permeate fraction and a nanofiltration retentate fraction;
- subjecting the nanofiltration permeate to a reverse osmosis step to produce a reverse osmosis permeate fraction and a reverse osmosis retentate fraction;
- combining the ultrafiltration retentate fraction with water and the reverse osmosis permeate fraction to form a first mixture;
- subjecting the first mixture to a diafiltration step to produce a diafiltration permeate fraction and a diafiltration retentate fraction;
- mixing the nanofiltration retentate fraction with the diafiltration retentate fraction, cream and the reverse osmosis retentate fraction to form a second mixture;
- and
- incubating the second mixture with lactic-acid generating bacteria to convert lactose within the second mixture to lactic acid to form a sugar-free dairy composition.
