Acacia Gums

Gum acacia, also called gum arabic, is a natural hydrocolloid produced by natural exudation of Acacia trees. This hydrosoluble gum has the unique property of being soluble at very high concentration in water, up to 50%. Recent studies have confirmed the presence of three fractions in the gum structure, each with its own properties. Studies have been conducted to investigate acacia gum as a protective film in citrus oil encapsulation. The stability and volatile compound retention after accelerated oxidation are shown. Also discussed are the analytical results on a citral and linalylacetate emulsion that was dried on acacia gum using two different drying techniques.
