Gum arabic is the dried gum from the stems and branches of sub-Saharan (Sahel zone) Acacia senegal and Acacia seyal (Leguminosae) trees and produced naturally as large nodules during a process called gummosis to seal wounds in the bark of the tree.

Gum arabic is used in food as a thickener, stabiliser, glazing agent and emulsifier, and is readily water-soluble.

Typical products include chewing gum, sweets, jelly, fondants, beer, soft drinks, fruit squash, wine.

May cause weak allergic reaction in some individuals. May act as an irritant.
