Acacia Gum
The short version
Gum arabic — exudate of acacia trees, the dominant beverage emulsifier and a clean-label dietary fiber.
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Where it comes from
Tapped from the wounded bark of Acacia senegal and Acacia seyal, native to the Sahel belt of Sub-Saharan Africa. Sudan is the dominant world producer. The dried tears are graded, milled, and spray-dried. One of the oldest commercial food additives — used in ancient Egyptian baking and Roman cosmetics.
How it's used
The classic beverage emulsifier — stabilizes citrus and cola flavor oils in soft drinks, suspends solids in instant coffee and dry beverage mixes. Builds chewy texture in gummies and marshmallows. Provides gloss in hard-candy panning. Increasingly marketed as a prebiotic soluble fiber in supplements.
Safety profile
ADI not specified — one of the safest food additives, with millennia of dietary exposure. Acts as a soluble fiber in the colon (well-tolerated at high intakes, ~30 g/day, where other fibers cause GI distress).
Physical & chemical properties
Off-white to pale amber powder or spray-dried granules. Very high cold-water solubility (~50% solutions are pourable) — unique among gums. Mildly acidic; stable across food pH range. Forms low-viscosity solutions even at high concentration, which is key to its beverage role.
Regulation worldwide
Permitted globally without restrictive limits.
