Guar Gum

Technical Grade

PLEASE NOTE: This product is not for human or animal consumption.

Guar Gum is a cold water soluble polysaccharide. Water solutions are odourless, of a pale, translucent off-white / grey colour, and almost neutral; Guar gum has 5 to 8 times the thickening power of starch; water solutions may be converted to a gel by small amount of borax; It is stable to heat and reduces friction drag of water on metals. Guar gum has synergistic interactions with other hydrocolloids such as Xanthan gum. 

Guar gum is manufactured by the wet mechanical grinding of endosperm Cyamopsis tetragonolobus. It is of high purity, fine granualtion, rapid hydrating and high viscosity. It is designed for applications where water binding, lubrication or high viscosity are required.
