Milk Powder

Definition

Milk is an opaque white liquid produced by the female mammals, and it provides the primary source of nutrition for newborns, before they are able to digest other types of food. Milk is an emulsion of butterfat globules within a water/protein-based fluid.
The early lactation milk is known as colostrum, and carries the mother's antibodies to the baby. It can reduce the risk of many diseases in the baby. The exact components of raw milk varies by species, but it contains significant amounts of saturated fat, protein and calcium as well as vitamin C. Cow's milk has a pH ranging from 6.4 to 6.8, making it slightly acidic.

Milk reception and pre-treatment of milk

Projecting a milk powder plant involves many unit operations one being the milk reception and pre-treatment. When milk isreceived at the factory, the quality is tested, before it is sent to the storage tanks. Pre-treatment typically involves pasteurization, separation of fat for standardization and then cooling before further storage and/or processing.

Powdered milk

Powder milk is a manufactured dairy product made by evaporating milk to dryness. 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. Another purpose is to reduce its bulk for economy of transportation. Powdered milk and dairy products include such items as dry whole milk, non-fat dry milk, dry buttermilk, dry whey products and dry dairy blends.
