Gum Arabic imparts the lowest viscosity to water of the normal, unhydrolyzed industrial gums, comparison of its solution viscosity with tragacanth karaya, ghatti, and corn fiber gums. Gum Arabic mixes well with other industrial gums, and at high concentrations ha suspending, stabilizing, and emulsifying properties. Gum Arabic solutions exhibit Newtonian viscosity at concentration up to 40%; but at higher concentrations, they acquire pseudoplastic character. Normally, Gum Arabic solutions are of pH about 4.5-5.5, which is near pH 6, then maximum viscosity is displayed. Solution viscosity decreases with age, following a zero rate order. This decrease is commonly due to hydrolysis; but Gum Arabic solutions are affected, as are solutions of other gums, b ultraviolet radiation and other glycosidic bond-breaking phenomena. Viscosity rises with increases in pH to about 6 the gradually falls to about pH 12 , where it again levels off. However, a more or less broad maximum viscosity is displayed over th range pH 2-10. As expected, when the pH is lowered to 3 or less, the ionization of the carbonyl group is repressed, and th polymer tends to gel and lose solubility. Flow Chart

Properties
Solubility : Gum Arabic is readily soluble in cold water and can yield solutions.
Film - Forming : Gum Arabic super film-forming properties make it ideal for some confectionery coatings and lithographic plate solutions.
Emulsifier : Gum Arabic produces highly stable emulsions making it very useful in the preparation of oil-in-water food flavour emulsions, particularly for citrus oils.
Colour : Colourless to pale straw colour.
Taste : Gum Arabic has no off-taste. The taste of flavoring products co-spray dried with Gum Arabic is not affected or delayed by Gum Arabic as the carrier.
