Summary: The present study found that 3% casein modulated by solution pH could be an outstanding stabilizer for oil-in-water Pickering HIPEs, with control over rheological properties and enhanced stability and viscoelasticity. The casein particles at different pH levels exhibited varied zeta-potential and three-phase contact angles, indicating their irreversible anchoring at the oil-water interface. The stability of the HIPEs against heating and sensitivity to frozen-thawing treatment were also observed, highlighting the potential of casein particles for providing electrostatic repulsion and steric hindrance to prevent coalescence or flocculation of oil drops in Pickering HIPEs.
