DEHYDRATION

• The milk can be preserved by dehydrating to various degrees. The dehydrated milk has a longer "shelf-life" than the milk preserved by pasteurization and refrigeration.
• Milk from which part or all of the water as been withdrawn is termed concentrated or dried milk (milk powder).
• More than 80 percent of milk is water. The best way to preserve milk S is by removal of water. It can be done bydrum drying or spray drying or by freeze drying.
