Guar Gum Agarbhathi grade

Product Description

guar gum is an exo-polysaccharidecomposed of thesugarsgalactoseandmannose.The backbone is a linear chain of β 1,4-linked mannose residues to which galactose residues are 1,6-linked at every second mannose, forming short side-branches. Guar gum has the ability to withstand temperatures of 80C (176F) for five minutes.

Solubility and viscosity

Guar gum is more soluble thanlocust bean gumdue to its extragalactosebranch points. Unlike locust bean gum, it is not self-gelling.Eitherboraxorcalciumcancross-linkguar gum, causing it togel. In water, it isnon-ionicandhydrocolloidal. It is not affected by ionic strength orpH, but will degrade at extreme pH and temperature (e.g. pH 3 at 50C).It remains stable in solution over pH range 5ï7. Strongacidscausehydrolysisand loss of viscosity and alkalies in strong concentration also tend to reduce viscosity. It is insoluble in most hydrocarbon solvents. The viscosity attained is dependent on time, temperature, concentration, pH, rate of agitation and particle size of the powdered gum used. The lower the temperature, the lower the rate at which viscosity increases, and the lower the final viscosity. Above 80, the final viscosity is slightly reduced. Finer guar powders swell more rapidly than larger particle size coarse powdered gum.
