Arabic Gum (Acacia) is a dried exudation obtained from the stems and branches of Acacia Senegal or Acacia Seyal trees. Although there are over 1100 Acacia species worldwide, Acacia Senegal and Acacia Seyal continue to be the most commercially exploited species of the entire Acacia resource. Which can only be found in Sudan, Chad, Senegal, and Nigeria, as part of the Arabic Gum belt. Sudan is a major Arabic Gum exporter. The areas of production is concentrated in the states of North Kordofan and Darfur.
Arabic Gum is widely used in the food and beverage industries, pharmaceuticals, cosmetics, textiles, Encapsulated Flavours, High Fiber Formulations, and painting.
