technical field

The utility model mainly relates to the technical field of Pickering emulsion preparation equipment, in particular to a microreactor used for the preparation of protein-based polyphenol Pickering emulsion.

Background technique

Pickering emulsion is a new type of emulsion stabilized by solid particles instead of traditional organic surfactants. Emulsions are dispersion systems composed of two immiscible liquid phases, in which the internal phase or dispersed phase is formed by droplets In the form of dispersing in the external phase or continuous phase, that is, it is not necessary to use an amphiphilic surfactant to reduce the interfacial tension, and a stable emulsion can be obtained by directly dispersing colloidal particles in the colloidal size range in the emulsion.
