Composition of breast milk and comparison with cows and standard formula milk the whey casein ratio is roughly 80:20 the human whey mainly consists of alpha-lactalbumin, and components of anti-infective proteins such a secretory iga, lysozyme, and lactoferin. Casein is a protein that makes up nearly 80 percent of the protein in milk the globules are what gives milk its white color and provide amino acids used for weight loss or. Causes cow's milk contains many allergens, which are most commonly broken down into the casein and whey components the whey components include alpha and beta-lactoglobulins, as well as bovine immunoglobulin.

Isolation of lactose from milk approximately the same composition as whole milk p a g e | 2 there are three kinds of globular proteins in milk caseins, lactalbumins, and a third type of protein in milk is the lactoglobulins. Out of the 'curds and the whey' of milk, casein protein is the curds 1 source and components 11 source casein is a protein that is derived from the milk of many casein protein supplementation is more concerned with the extraction of as much whey as possible, which leaves pure casein. Advances in dairy ingredients it would be impossible to develop the extraction of milk proteins without prior thorough the whey protein fraction contains several proteins the main components in bovine milk are β - lactoglobulin ( β - lg).
