Description
A polysaccharide derived from the seeds of the tamarind tree, Tamarindus indica, grown in India and southeast Asia but probably native to central Africa. Tamarind seeds contain about 65% Gum, 15-20% Protein, 6% Oil, and 3% ash. The carbohydrate portion contains Arabinose, Galactose, Xylose, galacturonic acid, and glucuronic acid. The gum dissolves in hot water to form a viscous solution that is high in Sugar. Tamarind gum is often used as a substitute for fruit Pectin and as an inexpensive textile sizing agent. It has also been used as a spray consolidant for flaking paint (Agrawal, 1984).
