Acacia gum (Gum Arabic)

Acacia gum, also known as gum arabic, is a natural exudate collected from the stems and branches of Acacia senegal and related species of acacia tree, primarily grown in the Sahel region of Africa. It is one of the oldest and most widely used food hydrocolloids, valued for its unique combination of emulsifying, thickening, and film-forming properties. In food, it stabilises oil-in-water emulsions in confectionery and beverages, encapsulates flavour oils, and provides a glossy coating on sweets and chocolate products.

JECFA evaluated acacia gum in 1975 and did not establish a numerical ADI, classifying it as not specified. Gum arabic is composed of complex polysaccharides and glycoproteins that are not significantly digested in the small intestine; they pass to the large intestine where they are fermented by gut bacteria, acting as a prebiotic fibre.

Acacia gum is approved globally — EU (E414), United States (GRAS), Japan, Korea, and everywhere. The prebiotic properties of gum arabic are increasingly recognised as nutritionally beneficial, supporting gut microbiota diversity. At very high intake levels (above 30 g/day) it can cause bloating or loose stools due to fermentation, but amounts used in food are typically far below this threshold. It is highly regarded as a natural, sustainable ingredient with both functional and health-supporting properties.
