Descripción general

Guar is extracted from the seeds of Cyamopsis tetragonoloba. It contains polysaccharides of galactomannans. Guar is used in thickening dye solution, production of paper and as a primary gelling agent in water-based slurry explosives. It acts as a fiber deflocculent and dry-strength additive and serves as an additive to dynamite for water blocking. Guar is used as a stabilizer, emulsifier and thickener in food products. It lowers cholesterol and glucose level. Guar aids weight loss and obesity prevention.

Aplicación

Guar has been used:
  • to maintain viscosity during in vitro starch digestion assay
  • to reduce the thinning rate of agarose gel
  • to study its effects on establishing 3D-like neural networks on microelectrode arrays (MEAs)

Acciones bioquímicas o fisiológicas

Guar gum has been shown to have numerous beneficial effects including improved glucose tolerance and attenuation of diabetic nephropathy.

Otras notas

Guar gum is isolated from the endosperm of the guar or gavar bean.
