Formulation of physiologically suitable infant foods necessitate reduction of protein and mineral levels from bovine milk, rich in lactose and whey proteins and containing appropriately low leavels of essential minerals. Demineralized whey is an ideal ingredient for infant formula. Demineralization of whey permits formulation of infant foods with a gross composition closest to mothers milk.

Lactose and its breakdown products, glucose and galactose have several metabolic and developmental functions in infants. Whey proteins made from milk are universally known for their immunological values for infants. That is the most important factor in mother’s milk considered best for babies. In low birth weight baby formula’s the Whey Protein are now made essential in ratio of 60:40 with Casein, hence fortification by whey protein powder is the only solution to achieve this.
