The state of dispersion of casein was investigated by use of UV difference spectroscopy and ultracentrifugal analysis. Sodium caseinate was aggregated by the addition of orthophosphate and citrate, due to the high ionic strength, and dispersed by more highly condensed meta- and polymeta-phosphates, to an extent dependent on the degree of phosphate condensation. Pyro-, tripoly- and tetrapoly-phosphate all cause aggregation at high concn., and dispersion at low concn.
