Skim milk powder (SMP) is a dairy product made by removing most of the fat from liquid milk and then drying it into a fine powder. It retains most of the nutritional content of milk, including protein, carbohydrates, vitamins, and minerals, while having a very low-fat content (usually below 1.5%). Industrial skim milk powder is widely used in food manufacturing, bakery, confectionery, and beverage industries due to its long shelf life, easy storage, and versatility.
