Xanthan gum is a high molecular weight substance with potential in improving emulsions
properties. The formulation composition was selected on Tween 80 ternary phase diagram and
was modified by the addition of xanthan gum at different concentrations (0.0% – 1.0%). The
main objective of this study was to determine the effect of xanthan gum on physicochemical
and rheological properties of rice bran oil emulsion. Xanthan gum concentrations have affected
the formulations droplet size. Yet, they did not show any effect on pH of the formulations.
However, an increase in xanthan gum concentration had increased the zeta potential value,
stability, and viscosity of the formulations. Xanthan gum also enhanced the flow behaviour of
