Description

Guar Gum

Appearance: White to light yellow powder

Particle size: **0 mesh

Viscosity: ***0

Properties:

Guar Gum is a polysaccharide with a straight chain of Dmannopyranose units joined by B (**4) linkages with a side branching unit of a single D-galactopyronase joined to every other mannose unit by L (**6) linkages. It is a white to yellowish-white powder, practically odourless and has a bland taste. It will disperse and swell almost completely in hot or cold water and is insoluble in organic solvents. The viscosity depends on temperature, time, pH, agitation rate and particle size of the powder

Specifications:

Guar gum is an economical thickener and stabilizer. Guar gum is more soluble than locust bean gum and a better emulsifier as it has more galactose branch points.

1, Unlike locust bean gum, it does not form gels but does show good stability to freeze-thaw cycles.

2, Guar gum shows high low-shear viscosity but is strongly shear-thinning. Being non-ionic, it is not affected by ionic strength or pH but will degrade at pH extremes at temperature for e. G. PH 3 at *0° C. With case in, it becomes slightly thixotropic forming a biphasic system containing caseinmicelles.

3, Guar gum retards ice crystal growth non-specifically by slowing mass transfer across solid/liquid interface. 4, Guar Gum is known as one of the best thickening additives, emulsifying additives and stabilizing additives.
