Nonfat dry milk, also known as skim milk powder, is a dairy product made by removing the fat and water from liquid milk. This process results in a fine, white powder that retains the nutrients found in milk, such as protein, calcium, and vitamins. It is commonly used in baking, cooking, and as an ingredient in various food products. Nonfat dry milk has a long shelf life, making it a convenient option for storage and use in recipes. It can be reconstituted by mixing it with water to create a liquid milk substitute. This product is often used in food manufacturing, infant formula, and emergency food supplies.
