INTERFACIAL TENSION BETWEEN AN INVERSE MICELLAR PHASE OF LIPID COMPONENTS AND AQUEOUS PROTEIN SOLUTIONS

Abstract
The interfacial tension of an inverse micellar solution in a lipid system and water or protein solutions has been deter mined with a surface tension apparatus based on the drop-volume principle. The interfacial tension of the inverse micellar solution towards water is very low, about 1.5 mN m−1. Investigated proteins, sodium caseinate, soy protein and blood plasma protein reduce the interfacial tension further, to about 1.0 mN m.
