Gum arabic, also known as acacia gum, is a natural gum made of hardened sap from two species of the acacia tree.  The gum is harvested commercially from wild trees in the Sahel region of Africa, from Senegal and Sudan to Somalia.  Historically, it was cultivated in Arabia and West Asia.  It is used primarily in the food industry as a stabiliser.  It is also used in printing, paint production, glue, cosmetics and various industrial applications.
