Depletion-flocculation in oil-in-water emulsions using fibrillar protein assemblies

摘要: This paper shows that low concentrations of beta-lactoglobulin fibrils can induce depletion-flocculation in beta-lactoglobulin-stabilized oil-in-water emulsions. The minimum required fibril concentration for flocculation was determined experimentally lengths about 3 and 0.1 microm. is two orders magnitude higher the short than long ones. These experimental results correspond well with a theoretical prediction based on model spinodal decomposition. In addition, rheological measurements were performed, verifying induced by depletion mechanism. this study show be tuned varying length fibrils.
