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).
