Galactose from Acacia gums

Acacia (gum arabic) is a dried gum from the stems and branches of the tree Acacia Senegal (Leguminosae/Fabaceae), abundant in the Sudan and Central and West Africa. Trees are tapped by removing a portion of the bark. The gum is used as a suspending agent, and adhesive and binder for tablets. The carbohydrate is a complex branched-chain material, which yields L-arabinose, D-galactose, D-glucuronic acid, and L-rhamnose on hydrolysis. Occluded enzymes (oxidases, peroxidases, and pectinases) can cause problems in some formulations, unless inactivated by heat. [Pg.476]
