Characterisation of gum exudates of Acacia senegal (gum Arabic) and Prosopis africana (Mesquite gum) sourced from two Nigerian tree species.

The study investigates physiochemical characteristics of samples of two tree gums, namely Acacia senegal and Prosopis africana gum produced and harvested from trees at two different geographical locations in Nigeria and The properties of the gum sourced from these tree species were compared with previously studied samples of gum Arabic harvested from Acacia senegal tree grown in Sudan. The results showed that Acacia senegal gums from Nigeria exhibits close similarity to the Sudanese Acacia senegal gum in terms of sugar and protein compositions as well as molecular mass distributions. The Physicochemical properties of the Prosopis africana gum were determined and compared with the gum Arabic. It was observed that, although some similarities exist in the composition of the two different gum samples, great differences were observed in content and general physicochemical properties. The results were also similar to those of mesquite gums studied in other part of the world. The study therefore revealed that Acacia senegal and Prosopis Africana gum have the same characteristics as gum Arabic sourced from Sudan.
