Functional Characteristics of Milk Proteins

In addition to their nutritional importance milk proteins have other functional characteristics which make them into valued ingredients. Most known milk products are based on technological changes in the milk’s protein components. The action of heat, pressure, alterations to pH value or enzymatic reactions lead to proteins forming structures. The characteristics of these products are dependent on the physicochemical condition and concentration of the proteins as well as the on milieu conditions.
