Acacia fiber is a highly soluble fiber which is sourced from the Acacia tree sap. The acacia mostly grows in Africa and some parts of India and Pakistan. The acacia fiber is also referred to as acacia gum or gum arabic.
Because of its high soluble-fiber content, acacia fiber is commonly consumed as dietary fiber supplement. In the food industry, gum arabic is used as a thickening agent or an emulsifier.
