Milk powder, also known as dehydrated milk, is milk that has been transformed into a dry form by removing the water it contains. This extends its shelf life and facilitates its transport and storage.

The process of making powdered milk usually involves two main steps. First, fresh milk is heated to remove some of the water it contains. Then the remaining liquid part is evaporated under vacuum, leaving behind solid particles of milk powder. Milk powder can be produced from whole milk, skimmed milk or partially skimmed milk.
