Na-caseinate/oil/water systems: Emulsion morphology diagrams

► Na-caseinate emulsion morphology diagrams have been determined. ► Different emulsion microstructures evidenced using cryo-SEM. ► Diffusion NMR measurements used to identify transitions between emulsion domains. ► Rheology confirms interface in tetradecane system differs from soybean oil/palm olein. ► Two- and three-dimensional protein networks formed within the emulsions.
