Claim:
1. A method for making a dairy composition comprising the steps of, cooling milk to a temperature between 42° F. and below 45° F.; subjecting the milk to an ultrafiltration step at a temperature between 42° F. and below 45° F. to produce an ultrafiltration permeate fraction and a ultrafiltration retentate fraction; subjecting the ultrafiltration permeate to a nanofiltration step at a temperature between 42° F. and below 45° F. to produce a nanofiltration permeate fraction and a nanofiltration retentate fraction; combining the ultrafiltration retentate fraction with the nanofiltration permeate fraction or water at a temperature between 42° F. and below 45° F. to form a mixture; subjecting the mixture to a diafiltration step at a temperature between 42° F. and below 45° F. to produce a diafiltration permeate fraction and a diafiltration retentate fraction; combining the diafiltration retentate fraction with one or more permeate and retentate fractions at a temperature between 42° F. and below 45° F. to form a blended composition; heating the blended composition at 146° F. for 30 minutes; cooling the heated composition to a temperature between 42° F. and below 45° F.; and, treating the cooled composition with lactase enzyme at a temperature between 42° F. to below 45° F. to form a dairy composition having a lactose content of 0.1 to 1.0%.
