Hashab on tree (raw form)

Gum Arabic is a complex mixture of polysaccharides and glycoprotein that is used primarily in the food industry as a stabilizer. It is edible and is a key ingredient in traditional lithography, used in:

  • Printing.
  • Paint production.
  • Glue.
  • Food (sweets, chocolates,….etc.)
  • Soft drinks (Coca-Cola, Pepsi)
  • Medical industry (Capsules shells)
  • Cosmetics and various industrial applications, such as viscosity control in inks and textile industries, and more a lot where this is not the place to give the details of uses.

Sudan is still the greatest producer of gum Arabic in the world, obviously more than 70% (Wikipedia) of the grade 1 gum Arabic (Acacia Senegal –known in Sudan as Hashab) & grade 2 (Acacia Seyal-known in Sudan as Talha) comes from Sudan, which is the real best quality definitely.
