Orthokinetic destabilization of a protein-stabilized emulsion by a water-soluble surfactant

Abstract

The coalescence rate of liquid droplets in a protein-stabilized emulsion containing water-soluble non-ionic surfactant has been studied in turbulent shear flow by monitoring the change in average droplet size with shearing time. The pronounced effect on orthokinetic stability of small surfactant additions may be attributed to increased adsorbed layer mobility without significant protein displacement from the interface.
