Preparation method for gliadin nanoparticles by electrospray

摘要

PURPOSE: A gliadin nanoparticle prepared by electrospray is provided to have an average particle size which is smaller than the particle size of gliadin particles prepared by desolvation and to increase zeta potential, thereby reducing aggregation of the nanoparticles. CONSTITUTION: A method for preparing gliadin nanoparticles comprises the steps of: dissolving gliadin in 65-80 (v/v)% ethanol solution to prepare a gliadin solution; and performing electrospray of the gliadin solution. The concentration of gliadin in the gliadin solution is 5-10 wt%. The flux and voltage difference of the gliadin solution during electrospray is 0.1-1 ml/hr and 12-18 kV, respectively. The diameter of a nozzle is 0.1-0.5 mm.
