Abstract

To evaluate the emulsion stability indices of W/O emulsion system, we developed the simple and sensitive "VOLUMETRIC METHOD". This technique involved the first step of homogenizing the milk fat-water system with Ultra-turrax T25, then the volume of the added water phase was measured immediately. After quiescent incubation in test tubes at room temperature for a desired storage time, the bottom volume of the separated water layer was measured. And then "emulsion stability index(ESI)" was calculated by the following equation : <TEX>$ESI
