Gum arabic’s mixture of saccharides and glycoproteins gives it the properties of a glue, and binder which is edible by humans.
Other substances have replaced it in situations where toxicity is not an issue, as the proportions of the various chemicals in gum arabic vary widely and make it unpredictable.
Still, it remains an important ingredient in soft drink syrups, “hard” gummy candies such as gumdrops, marshmallows, M & M’s chocolate candies and edible glitter, a very popular, modern cake-decorating staple. For artists it is the traditional binder used in watercolor paint, in photography for gum printing, and it is used as a binder in pyrotechnic compositions.
It has been investigated for use in intestinal dialysis.
