1998/7/3· Thin emulsion films stabilized with β-casein were studied by microinterferometry. The data demonstrate that the film thickness and intersurface adhesion are influenced by the electrolyte concentration, the prehistory of the protein solution, pH and the presence of fatty acids in the oil phase. A major shift of the film parameters occurs in the presence of calcium ions. The decrease of the
