Characteristics of Bovine and Ovine Whey Protein Concentrates Obtained by Ultrafiltration and Diafiltration Using Different Configuration Processes
The purpose of this study was to produce liquid and dry whey protein concentrates from bovine and ovine cheese whey from small and medium cheese manufacturing plants (LWPC and WPC). Because of the flexibility provided by batch ultrafiltration (UF) and diafiltration (DF), liquid bovine WPC with protein contents ranging from 43 to 66 percent (dry basis) and ovine WPC with protein contents ranging from 61 to 87 percent (dry basis) were produced (dry basis). Diafiltration in sequential dilution mode (DFsdm) did not significantly improve the composition of WPC liquid products when compared to conventional UF results. Using DF in volume reduction mode is superior to traditional UF (DFvrm) increased protein content by more than 20% Because ovine products have a higher protein content (62-84 percent on a dry basis), they are more appealing for manufacturing. Protein profiles differed depending on the origin of the whey and the concentration process. In comparison to the DFsdm mode, batch DFvrm produced richer protein products free of low molecular weight compounds. Finally, it is possible to conclude that the use of membrane technology enables the recovery and direct valorization of whey components in medium and small cheese companies, thereby resolving environmental issues and contributing to the circular economy.
