Viscosity Modification of Gum Arabic as a Means of Enhancing Gum
Quality
Abdelatif E. Mahmoud
Abstract:
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.
