Ultrafiltration
Ultrafiltration is a membrane filtration process operating at 2-10 bar pressure and allowing molecules of the size of salts and sugars to pass through the membrane pores, while molecules the size of proteins are rejected.
Typical UF applications are:
Dairy
- Milk
- Proteins standardisation, concentration and separation
- Cheese milk
- MPC
- Market milk
- Powder milk
- UF Concentration of cheese
-
- Feta and Domiati
- Queso Fresco types
- Concentration of Yoghurt, Ymer
- Concentration of Fermented Milk and Cream
- Fresh cultured cheeses (Quarg)
- Cream cheese
- Other fresh, soft cheeses, Mascarpone
- Protein concentration in sweet and acid whey
- WPC
- Recovery of WPC for cheese milk
- Special products i.e. yoghurt, desserts
- Protein concentration in sweet and in acid buttermilk
- Retentate for various foods
- Powder
