Xanthan gum properties

It has the highest viscosity of natural gum at low concentration (below 0.5%) and is soluble in cold water. The aqueous solution has a typical pseudoplastic flow. When sheared, the viscosity gradually decreases, and when the shear force decreases, the viscosity immediately recovers. The viscosity of the aqueous solution is basically constant in a large temperature range. For most gums, when the temperature increases by 5 ° C, the viscosity decreases by about 15%, while xanthan gum only decreases by about 5%. Xanthan gum is also salt-tolerant and will not salt out when heated in the presence of table salt. It has synergistic effect when mixed with locust gum, guar gum and other gums containing galactomannan. If combined with locust gum, it can be thickened significantly, and with guar gum to form a gel.
