Elamin Elhadi Elamin Ahmed*

The aim of this study was to investigate the physico-chemical properties of Albizia Amara gum. The gum samples used in the present study were obtained from South Kordufan State. The values obtained for the various physical and chemical properties were: Moisture content 7.81%, soluble fibre 0.13%, fat 0.197%, ash content 3.94% and protein 5.68%. The metal ions were determined (K, Na, Ca, Mg, Cd, Co, Pb and Zn), and the values are (1198.9 mg/kg), (22.97 mg/kg), (120.05 mg/kg), (1481.6 mg/kg), (0 mg/kg), (0.81 mg/kg), (0 mg/kg) and (0.9 mg/kg). The determination of the polysaccharides of the gum samples showed that the proportion of rhamnose (0.5541%), the proportion of arabinose (0.75075%), the proportion of galactose (0.65%) and the proportion of xylose and mannose (0%). The viscosity of the solution of 10% Albizia Amara gum is 25 cps at room temperature and a pH value of 4.18.
