The Pickering emulsions are stabilized by solid particles. Compared with traditional emulsions， they showed the advantages of better structural stability， biocompatibility， resistance to external pressure and lower toxicity to human environment， they manifested the ability to protect encapsulated bioactive substances and control their release. In recent years， functional Pickering emulsions are emerging in a variety of active materials， which are widely used in food， medicine and chemical industry. Based on the research of Pickering emulsion in recent years， the types of solid particles and the application progress of functional Pickering emulsion are summarized in the paper.
