Powdered milk is a dairy product made by evaporating milk to remove its moisture content. This process results in a fine powder that can be reconstituted with water to create liquid milk. It is often used as a convenient alternative to fresh milk, especially in areas where refrigeration is limited. Powdered milk is available in various forms, including whole, skim, and non-fat options. It is commonly used in baking, cooking, and food production, as well as in emergency food supplies due to its long shelf life. Additionally, it is a source of essential nutrients like calcium and protein.
