Tara gum is a white-beige powder that is obtained by grinding the endosperm of the seeds of Caesalpinia spinosa.
It is a galactomannan with the ratio of 3 mannose to 1 galactose units. This is a nonionic gum and is hence compatible with all other gums, surfactants and preservatives.
It is stable from a pH of 3,5 and can tolerate temperatures above 100 C. It has a good salt tolerance.
Tara gum is widely used in food and beverages. In cosmetics, it has a nice flow and no soapiness (compared to xanthan). Tara needs heating for full hydration.In cold water, it hydrates up to 70%.
It builds a gel with xanthan and has a synergetic viscosity increase with most other natural gums.
