Abstract: The molecular weight distribution of the gum exudate from A. oerfota was investigated using Gel Permeation Chromatography (GPC-MALLS). Emulsification properties of the gum were also examined, both results were compared to those from A. Senegal var. senegal gum. Molecular weights of A. oerfota gum, from two different location in Sudan, were 6.23x105 and 9.59x105 with the same radius of gyration (Rg) 178. Both gums show three fractions, AGP, (AG + GP) of molecular weights 4.77x105 and 5.5x105 respectively. The mass% of AGP is very small (1.11 and 0.84) in comparison to 98.89 and 99.16 for AG and GP respectively.Emulsification studies of A. oerfota show that it possesses a large droplet size, hence poor emulsification performance of a lower stability than that of A. Senegal.
