The world market of guar is estimated at 150,000 tons annually. India accounts for about 80 percent of the global trade in guar products. India exported 11 billion rupees worth of guar products in 2007/08 financial year ending March 2008. Pakistan trails India in the global trade. Industrial guar gum is the most sought-after guar product, and accounts for about 45 percent of the total demand. Industrial gum is used as a controlling agent in oil wells to facilitate easy drilling and prevent fluid loss. Guar gum powder is the most preferred thickening and binding ingredient used as baking premixes for technical consideration. In this application fine mesh powder that yields 3500 and 5000cps viscosity is recommended for freshly baked articles (bread). It increases dough and bread yield , improves crumb condition, improves fresh keeping qualities, dough elasticity, enhances texture, maximises the volume of baked articles, enriches fibre, enhances browning and round off the ideal bread flavour.
Guar Gum is a white to yellowish white powder and is nearly odorless. Fine finished Guar Gum Powder is available in different viscosities and granulometries depending on the desired viscosity development and applications.
Guar Gum is a natural high molecular weight hydrocolloidal polysaccharide composed of galactan and mannan units combined through glycosidic linkages, which may be described chemically as galactomannan.
Guar gum is a cold water soluble polysaccharide, consisting of mannose and galactose units. This ability to hydrate without heating makes it very useful in many industrial and food applications.
Dissolved in cold or hot water, guar gum forms a slime of high viscosity. Guar's viscosity is a function of temperature, time, and concentration. Solutions with different gum concentrations can be used as emulsifiers and stabilizers because they prevent oil droplets from coalescing. Guar gum is also used as suspension stabilizer.
