  • Depletion Flocculation of Beverage Emulsions by Gum Arabic

    Flocculation could be nondestructively monitored by measuring the decrease in ultra-sonic attenuation of the emulsions These results show that depletion flocculation by gum arabic and modified starch can have an adverse effect on the stability of beverage emulsions Key Words: gum arabic, modified starch, beverages, emulsions, flocculation.
