Guar gum is soluble in cold water and become viscous solution. It is dissolved quickly when it is solved in hot water.
It shows pseudoplastic flow (pseudoplasticity) in which the apparent viscosity decreases as the solution shear stress increases.
Most of the 1% solutions have a viscosity of 3000 to 5000 mPa.s, but we also have products with lower viscosity
It interacts with other polysaccharides. For example, when used in combination with xanthan gum, it exhibits high viscosity due to its synergistic effect. The viscosity is maximum when the mixing ratio of guar gum and xanthan gum is 4: 1.
