Guar gum powder is extracted from seeds of the Cyamopsis Tetragonoloba. Chemically, it is a polysaccharide made of sugars, galactose, and mannose. The polysaccharide galactomannan present in the endosperm of the guar plant is a hydroxyl polymer. When it gets in touch with water it forms hydrogen bonds and it provides the required viscosity and thickening. It is nearly odorless and tasteless; it is white to yellowish-white powder. Guar gum powder has excellent viscosity and stability in cold water because it has high galactose: mannose proportion. The ratio of mannose to galactose in the guar gum has been evaluated at 2:1. The special properties of guar gum powder produced in Tamil Nadu have made it the most preferred and suitable product in various industrial applications.
