Gum arabic is the exudate of the plants Acacia senegal and Acacia seyal. The largest deposits of this plant are in sub-Saharan Africa. It is obtained from the sap of the trees. For this purpose, the peeled bark of the tree is cut into. After approx. 20-30 days, the dried exudate that seeps out can be harvested. Polygal AG markets self-produced gum arabic for food and pharmaceutical applications.
