Viscosity modification of gum arabic as a means of enhancing gum quality

Metal ions of gum arabic were removed by ion exchange to yield the free acid form. Arabate salts were prepared using monovalent and divalent metal ions. Addition of monovalent metal ions was found to double the viscosity of the gum as compared to the viscosity of the raw gum and more than triple the viscosity of the free acid form at low solution concentration. At high solution concentration, monovalent ions increased the viscosity of the solution by about 50% over that of the raw gum. Divalent ions failed to increase the viscosity at low solution concentration, while an increase of 14% over that of the raw gum was observed at high solution concentration
