Gum Arabic from Acacia senegal (Wild) has been fractionated by a foaming method into two fractions, high protein fraction (HPF) that represents 30% of the gum and a low protein fraction (LPF) which represents 70% of the gum. A comparative study between the crude gum and the two fractions carried out in the scope of their physio-chemical properties. A proximate analysis of the crude gum and the two fractions(HPF and LPF respectively) revealed that, the moisture content(10.11,10.04 and 10.05) and specific rotation( -31,-30 and -30) were insignificantly different whereas ash%(3.7,3.33 and 3.03), acid insoluble ash%(0.3,0.135 and 0.145), acid insoluble matter% (0.18, 0.55 and 0.58) and pH ( 4.49, 4.47 and 4.25) were significantly different . The nitrogen (0.28, 1.51 and 0.007) and protein content (1.85, 10.01 and 0.05) and the intrinsic viscosity (17, 44.5 and 6 cm-3/g) were, highly, significantly different. Mineral composition of crude gum, fractions HPF and LPF revealed that LPF had the...
