摘要：
The invention relates to a process for treating animal skim milk and sweet whey and/or acid whey, comprising: (a) ultrafiltration (UF1) of a first liquid composition comprising animal skim milk with 70 –90 wt% casein and 10 –30 wt% whey proteins, based on total protein, over a first ultrafiltration membrane having a molecular weight cut-off of 2.5 –25 kDa using a volume concentration factor of 1.5 –6 to obtain a retentate (UFR1) and a permeate (UFP1)； (b) ultrafiltration (UF2) of a second liquid composition comprising sweet whey and/or acid whey over a second ultrafiltration membrane having a molecular weight cut-off of 2.5 –25 kDa using a volume concentration factor of 2 –15 to obtain a retentate (UFR2) and a permeate (UFP2)； and (c) mixing the UF retentate originating from step (a) with the UF retentate originating from step (b) to obtain a mixture of UF retentates.
