Description générale

Tragacanth is a gum commonly found in the sap of various Middle Eastern legumes. It is commonly used as freezing-embedding medium for tissue preservation.

Application

When mixed with water, tragacanth yields a colloidal hydrosol. The bassorin fraction (which consists of approx. 60-70% of the compound) swells to form a gel. This swelling gives the gum tragacanth the ability to form thick, viscous dispersions and pastes. It is an effictive emulsion stabilizer.

Autres remarques

A complex mixture of polysaccharides including tragacanthin and bassorin.
