Gum Arabic Characteristics

Gum Arabic consist mainly of high molecular weight polysaccharides and their calcium, magnesium, which on hydrolysis yield arabinose, galac-tose, rhamnose, glucuronic acid. The weight has been reported to be between 200,000 to 300,000 and as high as 600,000.

Specifications of Gum Arabic:
SYNONHYMS Gum Arabic, Gum hashab Acacia senegal, Kordofan, GUM NO.414
DEFINITION Gum Arabic is dried exudation obtained from the stems and branches of Acacia Senegal. (L) Willenow (Famleguminosae). It consists mainly of salts of acidie arabinogalactan protein complex, which on hydrolysis yields galactose arabinose, rhamanose, glucuronic acid and 4-methoxy glucuronic acid.
FUNCTIONAL USES The article of commerce is further specified as to Viscosity, Emulsifier, Stabilizer, Thickening and Encapsulating agent.

Gum Arabic Properties:
SOLUBILITY Can yield solutions up to 55% concentration. Gum Arabic is truly soluble in cold water. Other gums are either insoluble in cold water or form colloidal suspensions, solutions not true.
VISCOSITY A 20% aqueous solution will give less than 100 cps, i.e. Gum Arabic is not very viscous at such concentrations. High viscosity is obtained only at concentrations of 40% - 50%
FILM-FORMING Gum Arabic's superb film-forming properties make it ideal for some confectionery coatings and lithographic plate solutions.
EMULSIFIER Gum Arabic produces highly stable emulsions making it very useful in the preparation of oil-in-water food flavour emulsions, particularly for citrus oils.
COLOR Colorless (top quality) to pale straw color (average quality).
TASTE Gum Arabic has no off-taste. The taste of flavoring products co-spraydried with Gum Arabic is not affected or dulled by Gum Arabic as the carrier.
FIBER Nutritional experts can regard Gum Arabic as 95% "Soluble Fiber," according to the latest evidence.
CALORIC VALUE Officially recognized in the U.S.A. as being under 1 Kcal per gram. 
Generally defined as POLYSACCHARIDE DIETARY FIBER WITH REDUCED CALORIC INTAKE.
CHOLESTEROL REDUCER Human dietary intake studies have indicated a reduction in blood cholesterol levels when above average amounts of Gum Arabic (25 grams per day) are ingested in solution.
TOXICOLOGICAL STATUS "ADI not specified" (JEFCA + EEC):
"Generally Recognized as Safe" (GRAS) (USA).
