Whole milk powder is made by evaporating and spray-drying fresh pasteurized whole milk. The process removes most of the water content from the milk, leaving behind a dry powder that can be reconstituted with water to make liquid milk.
Whole milk powder contains all of the components found in fresh milk, including protein, fat, lactose, and vitamins and minerals like calcium and vitamin D. It is often used as a convenient, shelf-stable substitute for fresh milk in recipes, or as an ingredient in baked goods, confectionery products, and other food applications. It has a longer shelf life than fresh milk, and is easier to transport and store, making it a popular choice in the food industry.
