ANALYSIS OF MODERN METHODS OF MILK PROTEIN FRACTIONATION
The methods of milk protein fractionation are analised: chromatography (ion exchange, affinity and hydrophobic chromatography), membrane methods and combined methods. The new prospective methods have been discribed, such as aqueous two-phase separation (ATPS) and magnetic fishing. The combination of the methods together have been estimated from a perspective of their effectiveness: yield and purity of the major proteins. The prospective methods of casein separation are also considered in considering with the growing interest in the high puriied fractions of casein and its peptides.
