Ghatti is a gum derived from the sap of Anogeissus latifolia, commonly known as the Axlewood tree, which is native to India, Myanmar, Nepal, and Sri Lanka. The raw gum exudes from the bark and hardens in the sun, forming glossy off-white to brown tear-shaped droplets.
Ghatti is sold in the form of a powder that varies from off-white to brown depending on the level of purification, with the higher grades generally appearing lighter than the lower grades. It is a natural polysaccharide that has a neutral taste and is almost odourless. Ghatti is up to 90% soluble in water and forms a colloidal dispersion that is highly viscous at concentrations of around 3–5%. It is a good emulsifier and acts as a buffer against small amounts of acid or alkali, maintaining a pH of around 4.8. Ghatti is sometimes used as a substitute for Gum Arabic.
