| Definition: Acacia is the air-harden, gummy exudate flowing naturally from or obtained by incision of the trunk and branches of Acacia Senegal. Appearance: Spheroidal, oval, or reniform pieces (tears) of varying diameter from about 1 to 3 cm, yellowish white, yellow, or pale amber sometimes with a pinkish tint, friable, opaque, frequemtly with a cracked surface, easily broken into irregular, whitish or slightly yellowish angular fragments with conchoidal fracture and a glassy and transparent appearance. In the center of unbroken tears there is sometimes a small cavity. Iodine Test: The powdered gum is not coloured blue(indicating absence of starch) or red (indicating absence of dextrin) by the iodine test solution. Characteristics: Odourless;tasteless and adheres to the tongue. Solubility: It is almost completely but very slowly soluble in twice its weight of water, leaving only a very small residue of vegetable particles. The liquid(mucilage) obtained is colourless or yellowish dense viscous,adhesive, translucent and weakly acidic to blue litmus paper. Solubility: Practically insoluble in ethanol(96%) and in ether. Specific Optical Rotation: range of -26 deg to -34 deg A 10% w/v solution in water is laevorotatory. Nitrogen Content: Kjeldahl nitrogen content of 0.27-0.39 Loss on Drying: When dried at 100 deg to 105 deg; loses not more than 15.0% of its weight. Chemical Constituents: Gum Acacia consists principally of Arabin, a compound of Arabic acid with calcium, varying amounts of the magnesium and potassium salts of the same acid being present. Gum arabic is used in the food industry to fix flavours and as an emulsifier, to prevent the crystalization of sugar in confectionery products, as a stabilizer in frozen dairy products; its viscosity and adhesive properties find use in bakery products, and as a foam stabilizer and clouding agent in beer. In the pharmaceutical industry gum arabic is used as a stabilizer for emulsions, binder and coating for tablets, and as an ingredient in cough drops and syrups. In cosmetics it finds use as an adhesive for facial masks and powders, and to give a smooth feel to lotions. |
