Skim milk powder is a dairy product made by removing the fat from whole milk and then drying the remaining liquid. This process results in a fine, white powder that retains most of the nutrients found in milk, such as protein, calcium, and vitamins. Skim milk powder is often used in baking, cooking, and as a nutritional supplement. Because it has a long shelf life, skim milk powder is a convenient option for those who may not have access to fresh milk. It can be reconstituted by mixing it with water, making it a versatile ingredient in various recipes, including smoothies and soups.
