Description
A water soluble exudate from the stems of Angeissus latifolia trees native to India and Sri Lanka. Ghatti gum is a complex polysaccharide containing arabinose, Galactose, Mannose, Xylose, galacturonic acid, and glucuronic acid. When mixed with water, ghatti forms a thixotropic solution whose viscosity increases geometrically with concentration. Gum ghatti dispersions have emulsification and adhesive properties equivalent to or superior to those of Gum arabic and it is used in many of the same applications. Gum ghatti is also used as a dye thickener, a textile size, and an adhesive.
