Relation Between Micellar and Serum Casein in Bovine Milk

Little or no additional casein dissolved when milk was diluted with large volumes of milk dialysate.Some dissolution of micellar to serum casein occurred when sedimented micelles were redispersed in ultrafiltrate mechanically, but the concentration of serum casein remained far below that of the original milk.It is concluded that micellar and serum casein do not form an equilibrium system controlled by the solubilities o£ the various caseins.
