Abstract
The present disclosure provides a method for preparing biopolymer particles, said method comprising a membrane emulsification of a dispersed phase into a continuous phase wherein the dispersed phase comprises the biopolymer in a solvent, and wherein passing the dispersed phase through the membrane forms an emulsion of the biopolymer in the continuous phase; and a phase inversion with an anti-solvent to form particles of the biopolymer; wherein prior to (b), the emulsion is cooled to a temperature, T1. Also provided are biopolymer particles obtained from the method.
