Whey protein basics


Whey is a by-product of cheese production. During curdling, casein is separated from the water-soluble component of milk which is the whey. After the processing of whey, it is launched onto market in the form of powder which has high biological value and is easily digestible. The biggest advantage of whey products is that they provide the body with good quality protein, and in addition to this, they do not contain such components as fat or carbohydrate in large quantity.
