The flexibility implemented by batch ultrafiltration (UF) and diafiltration (DF) allowed for the production and ovine WPC with 61 -87% (dry basis). Diatiltration, performed in of liquid bovine WPC with 43-66% protein contents (dry basis) sequential dilution mode (DFsdm) did not improve significantly the composition of WPC liquid products comparing to the results achieved by conventional UF. However, using DF in volume reduction mode (DFvrm) protein content was increased more than 20% comparing to conventional UF. Ovine products showed higher protein levels (62-84% dry basis) what makes their manufacture attractive. Protein profiles varied with the whey origin and with the concentration process. Using batch DFvrm was possible to obtain richer protein products free of low MW compounds.展开更多
