Whey Protein Isolate (WPI)
Whey Protein Isolate is a dietary supplement and food ingredient created by separating components from milk. Whey is a by-product of the cheese-making process. Whey isolates have had their base component (water) removed and are generally considered almost lactose and cholesterol free — they are typically at least 90% protein. Whey protein isolates are also widely used in infant formula to provide a natural source of amino acids for optimal growth and development, as well as for protein fortification of bars, beverages, dairy products, extruded snacks and cereals and other food product.
