Bulk and Interfacial Behavior of Potato Protein-Based Microgels.

This study aims to understand the bulk and interfacial performance of potato protein microgels. Potato protein (PoP) was used to produce microgels of submicrometer diameter via a top-down approach of thermal cross-linking followed by high-shear homogenization of the bulk gel. Bulk "parent" gels were formed at protein concentrations [PoP] = 5-18 wt %, which subsequently varied in their bulk shear elastic modulus (') by several orders of magnitude (1-100 kPa), ' increasing with increasing [PoP].
