Investigation of Stability of Emulsions Containing two Gums from the Gummiferae Family and Combinations

Acacia seyal var. seyal (ASY) and Acacia tortilis var. raddiana (ATR), both of which are members of the Gummiferae series, were used as representative gum samples to make oil-in-water (O/W) emulsions with different amounts of isopropyl myristate (IPM) oil. According to an analysis of the emulsion's oil droplet size , ATR produced smaller oil droplets than ASY gum. Phase separation stability tests showed very stable emulsions, and morphological analysis of the emulsion showed that both gums formed compact spherical oil droplets. Blended gum emulsions with a 20% IPM oil concentration were prepared. The appearance of blended gum emulsions after they were incubated for seven days at 45°C, displayed spherical, dense, and smaller droplets compared to the individual gums. Phase separation tests for blended emulsions indicated exceptional stability, particularly in the 3:7 ratio of ASY to ATR combination.
