Sodium caseinate/carboxymethylcellulose interactions at oil-water interface: Relationship to emulsion stability

► CMC adsorbed to CN-coated droplets at acidic pH via electrostatic interaction. ► Droplets coated by CN/CMC were stable to pH changes and repulsion flocculation. ► Droplets coated by CN/CMC remained stable at 150 mM NaCl concentration.
