Applications
- Ultrafiltration of Whole Milk
- Reduce transportation costs - On the Farm Concentration
- Protein fortification of milk for natural cheese production - 'Alternate Make' Procedures
- Manufacture of 'Cheese Base' for Processed Cheese
- Ultrafiltration of Skim Milk
- Protein fortification of milk for natural cheese production - 'Alternate Mix' Procedures
- Dairy ingredients such as Milk Protein Concentrates (MPC)
- Health Food such as Lactose free or -reduced milk, reduced carbohydrate dairy products such as yogurt, ice cream, frozen dessert etc.
On the Farm Milk Ultrafiltration
- In 1996 FDA approved a pilot project for one farm to produce Ultrafiltered milk to be used as an ingredient for 'Cheddar Cheese'
- Patented process using 'Plug Flow'
- Production has since been expanded to additional Farms
|
|
|
 |
- Ultrafiltered Milk is being shipped to Cheese Plants in Idaho, Illinois, Iowa, Minnesota, North Dakota, Ohio, Pennsylvania, South Dakota and Wisconsin
- In October 2004, FDA has allowed 'Recirculation stages' with safeguard to maintain low processing temperatures.
- FDA is considering, but not acted on revising Standards of Identity of Cheeses to reflect use of Ultrafiltered Milk.
- Further advancement of the process is dependent on economic disposal / utilization of permeate.
