Interactions between whey protein isolate and gum Arabic.

Abstract

In this study we have attempted to understand the nature of "charge interactions" between two negatively charged biopolymers (whey protein isolate, WPI and gum Arabic, GA) and, consequently, why their mixture exhibits better interfacial activity. Surface tension (gamma(0)) measurements indicated that at ca. 1 wt.% of the biopolymer mixture (3:1 wt. ratio… (More)
