| Abstract: | Different methods of precipitation of arabic acid from natural gum arabic are compared in terms of yield and molecular weight derived from gel chromatography experiments. All of the precipitation methods used gave products which were closely similar in terms of n, but precipitation with HCl/acetone and HAc/ethanol gave low yields (25 and 3%, respectively). |
