Tara gum is the endosperm of the seeds of the tara tree (Cesalpinia
spinosa lin). The plant is native to South America where it
grows as tree or bush. Today, tara is also cultivated in Morocco
and East Africa.
Like guar gum and carob bean gum, tara gum is a galactomannan,
comprising approximately 25% of galactose (for comparison, guar
gum E412 contains about 34%, carob bean
gum about 20% of galactose).
Tara gum is partly soluble in cold water. The solution is more
viscous than a guar gum or carob bean gum solution of the same
concentration. Like carob bean gum, it has a gelling effect
together with xanthan and increases the gelling properties of
agar (see E406) and carrageenan (see
