Ultra-stable Pickering emulsion stabilized by a natural particle bilayer

Abstract

Ultra-stable Pickering emulsions synergistically stabilized by zein nanoparticles and starch nanocrystals were successfully prepared and the stabilization is ascribed to the double-layer shell of binary particles. The as-prepared Pickering emulsions showed unprecedented stability against centrifugation up to 20 000g and against environmental stresses such as pH change and high temperature.
