GUAR GUM (Fast Hydrating Guar Gum) is a natural galactomannan polysaccharide obtained from ground endosperm of the legume Cyamopsis tetragonolobus, an annual plant which grows mainly in arid and semiarid regions of India. It’s a fast hydrating guar gum to be used in various oil field applications especially in hydraulic fracturing as carrier for proppant. When compared to the other viscosifiers could be cross-linked successfully using a metal ion based cross-linking agent. Upon cross linking the resultant fluid can handle high concentrations of proppant and provides increased fracture width and penetration.
In addition, the gels thus formed vary widely in gel character and texture. Hence, knowledge of the conditions required for gelling of particular hydrocolloid dispersion, the characteristics of the gel produced and the texture it confers are very important aspects to design a specific food formulation. The important gums that find application in food as gelling agents include alginate, pectin, carrageenan, gellan, gelatin, agar, modified starch, methyl cellulose and hydroxypropylmethyl cellulose.
