Chemically, gum Arabic is a solidified descending sap exudate produced naturally or as a result of an incision on the trunk at the foot of trees of the acacia family. It is harvested mainly in Saharan Africa.

Chemically, gum Arabic is an highly ramified acid polysaccharide often found in the form of potassium salts or of mixtures of magnesium and calcium. Gum Arabic is commercially sold as a powder or unmilled crystals more or less round with colors ranging from pale to brownish yellow.

Gum Arabic is tasteless, odorless and edible. It is soluble in water, insoluble in alcohol. Even at concentration of 30 to 40%, gum Arabic is still very low in viscosity. In the industry it is mainly used as emulsifier, especially for citrus oils, as a protective colloid in the emulsions and as a carrier for flavorings.

Gum Arabic is also used in the manufacture of certain incenses because of it’s binding properties, as an emulsifier in some carbonated beverages such as Coca-Cola and even in the composition of certain adhesives; smoking papers for smokers and postal stamps.


In painting gum Arabic is the traditional binder of watercolor and gouache. It can also be used in liquid solutions as painting medium or as a constituent in the manufacture of traditional dry pastels, although gum tragacanth is primarily used. A diluted solution of gum Arabic may also be used as a fixative for dry pastel or charcoal.

In photography, gum Arabic is also used in the gum dichromate process and for certain retouches and alterations.
