Whole milk powder, on the other hand, contains on average 25–27% protein, 36–38% carbohydrates, 26–40% fat, and 5–7% ash (minerals). According to USAID, the typical average amounts of major nutrients in the unreconstituted nonfat dry milk are (by weight) 36% protein, 52% carbohydrates (predominantly lactose), calcium 1.3%, potassium 1.8%. Milk powders contain all 21 standard amino acids, the building blocks of proteins, and are high in soluble vitamins and minerals. Alternatively, when measuring by volume rather than weight, one cup of fluid milk from powdered milk requires one cup of water and one-third cup of powdered milk. The weight of nonfat dry milk (NFDM) to use is about 10% of the water weight. Like other dry foods, it is considered nonperishable and is favored by survivalists, hikers, and others requiring nonperishable, easy-to-prepare food.īecause of its resemblance to cocaine and other drugs, powdered milk is sometimes used in filmmaking as a non-toxic prop that may be insufflated. It is widely used in many developing countries because of reduced transport and storage costs (reduced bulk and weight, no refrigerated vehicles). Powdered milk is also a common item in UN food aid supplies, fallout shelters, warehouses, and wherever fresh milk is not a viable option. Many no-cook recipes that use nut butters use powdered milk to prevent the nut butter from turning liquid by absorbing the oil. Powdered milk is also widely used in various sweets such as the Indian milk balls known as gulab jamun and a popular Indian sweet delicacy (sprinkled with desiccated coconut) known as chum chum (made with skim milk powder). Powdered milk is frequently used in the manufacture of infant formula, confectionery such as chocolate and caramel candy, and in recipes for baked goods where adding liquid milk would render the product too thin. The drying method and the heat treatment of the milk as it is processed alters the properties of the milk powder, such as its solubility in cold water, its flavour, and its bulk density.įood and health uses Incolac powdered milk However, powdered milk made this way tends to have a cooked flavour, due to caramelization caused by greater heat exposure.Īnother process is freeze drying, which preserves many nutrients in milk, compared to drum drying. Milk is applied as a thin film to the surface of a heated drum, and the dried milk solids are then scraped off. Īlternatively, the milk can be dried by drum drying. The resulting concentrated milk is then sprayed into a heated chamber where the water almost instantly evaporates, leaving fine particles of powdered milk solids. Pasteurized milk is first concentrated in an evaporator to approximately 50 percent milk solids. In modern times, powdered milk is usually made by spray drying nonfat skimmed milk, whole milk, buttermilk or whey. Grimwade took a patent on a dried milk procedure, though William Newton had patented a vacuum drying process as early as 1837. The first commercial production of dried milk was organized by the Russian chemist M. While Marco Polo wrote of Mongolian Tatar troops in the time of Kublai Khan who carried sun-dried skimmed milk as "a kind of paste", the first modern production process for dried milk was invented by the Russian doctor Osip Krichevsky in 1802. This is the original container from 1947, provided by the Ministry of Food in London, England History and manufacture Modified dry whole milk, fortified with vitamin D. Powdered milk is used for food as an additive, for health (nutrition), and also in biotechnology (saturating agent). Many exported dairy products conform to standards laid out in Codex Alimentarius. Powdered milk and dairy products include such items as dry whole milk, nonfat (skimmed) dry milk, dry buttermilk, dry whey products and dry dairy blends. Another purpose is to reduce its bulk for the economy of transportation. One purpose of drying milk is to preserve it milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. Powdered milk, also called milk powder, dried milk, or dry milk, is a manufactured dairy product made by evaporating milk to dryness. Not to be confused with Evaporated milk or Condensed milk.
