Guar Gum , also called guaran, is a galactomannan. It is primarily the ground endosperm of guar beans. The guar seeds are dehusked, milled and screened to obtain the guar gum. It is typically produced as a free flowing, pale, off-white coloured, coarse to fine ground powder.
Guar Gum Properties
Chemical composition:
Chemically, guar gum is a polysaccharide composed of the sugars galactose and mannose. The backbone is a linear chain of ß 1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side branches.
Solubility:
Guar Gum is water soluble.
Thickening:
Guar gum is economical because it has almost 8 times the water-thickening potency of corn starch. Only a very small quantity is needed for producing sufficient viscosity. Thus, it can be used in various multi-phase formulations: as an emulsifier because it helps to prevent oil droplets from coalescing, and/or as a stabilizer because it helps to prevent solid particles from settling.
Industrial applications of Guar Gum.
Applications of Guar:
Guar gum is used in Food, Oil drilling, Textile printing, hydroseeding and many more.
