white or yellowish white particles of varying sizes, fragments or powder, surface cracks, friable, odorless, light and sticky, relative density of 1.35~1. 49. Soluble in water, insoluble in ethanol, oil and organic solvents. Gradually dissolved in water into acidic viscous liquid, solubility of about 50%; Aqueous solution in pH 6-7 between the maximum viscosity; Concentration below 40%, the solution is Newtonian liquid characteristics; Concentration greater than 40%, pseudoplasticity of the liquid can be observed. A stable coacervate can be formed with gelatin or albumin.
collect the natural exudates from the stems and branches of Acacia Leguminosae, or cut the bark to collect the gelatinous exudates, after removing the impurities and drying, grind and sieve, made of different types of products, can also be obtained by spray drying method. If the colloid is wet by rain before harvesting, the quality of the glue will be reduced.

is widely used in the food industry. In the candy can be used as crystallization prevention agent and emulsifier; In the milk can be used as a stabilizer; In the food flavor can be used as a flavor aid; In the emulsion flavor, gum arabic mixed with other gums, it can provide a good soft feeling; It can be used as an excipient and a fragrance promoter in the powder flavor, and can form a protective film around the flavor particles, prevent oxidation, evaporation and have a moisturizing effect. In pharmaceutical production, gum Arabic can be used as an emulsifier, a suspending agent, a binder, a sustained-release material, and a Microcapsule film material for production of emulsions, suspensions, tablets, granules, capsules, microcapsules, and the like.
