The Modification and Application of Food Grade Pickering Emulsion

Pickering emulsion, stabilized by solid particles, is a promising emulsion system of great significance. It has attracted much attention in the food field because of its strong stability, environmental friendliness, and other advantages. This paper focuses on the Pickering emulsion stabilized by different solid particles, including proteins, polysaccharides, and polyphenols. Due to the limitations of natural solid particles in stabilizing emulsions, this paper further discusses the physical, chemical, and biological modification of solid particles to improve their emulsifying property and stability, such as pH and ultrasound. Finally, the application of Pickering emulsion in the food industry was introduced in detail, such as delivery of active substances, fat substitutes, food preservation, and 3D printing, in order to provide a theoretical basis and technical support for the further development of Pickering emulsion in the food industry.
