The present study compares the emulsifying properties of Acacia senegal gum, glucuronic acid (arabic acid) and glucuronates (arabate salts) in oil-in-water (O/W) emulsions. Emulsifying properties of each hydrocolloid were evaluated in terms of emulsion droplet-size distribution. Emulsion of Na, Ca and Mg glucuronates show stability until 3 days while Acacia senegal gum emulsion forms multiple peaks after 3 days and completely separates after 7 days.
