Guar Gum is a natural polysaccharide extracted from the endosperm of the guar bean (Cyamopsis tetragonoloba). It appears as an off-white to cream-colored powder with a neutral odor and bland taste. Guar Gum is a galactomannan composed mainly of mannose and galactose units, known for its excellent water-binding, thickening, and stabilizing properties. It forms highly viscous solutions even at low concentrations, making it a versatile hydrocolloid used widely across food, pharmaceutical, cosmetic, oilfield, and industrial applications.
