All these galactomannan gums possess high water binding capacity which can generate highly viscous dispersions making them effective thickeners and stabilizers. Recently, FG has received particular interest due to its functional properties (viscosity, emulsification, gelation, foam formation, and stability) and the ability to develop weak gels at about 1 wt% concentrations [5]. One of the most expected features of biopolymers is their effectiveness in providing highly viscous dispersions at a lower concentration [6]. Therefore, it would be important to know how FG behaves at various dispersion concentrations and how its structure and functionality is related
