Qu'est-ce que Gum Arabic / Acacia Gum (E414) ? Applications, dosage, alternatives et spécifications

gomme Arabic, also known as Acacia gomme, gomme Acacia, est un naturel high-molecular-weight water-soluble polysaccharide exuded from the branches and trunks of Acacia trees (Acacia senegal and Acacia seyal). It est unn important category of naturel hydrophilic colloids, with wide application value in the global industrie alimentaire, pharmaceutical industry, cosmetic industry, and printing industry. Its CAS number is 9000–01–5, EINECS number is 232–519–5, CNS number is 20.008, INS number is 414, and UE E number is E414. gomme Arabic est dérivé de the exudates of Acacia senegal (L.) Willdenow and Acacia seyal trees. When the bark is damaged, the tree secretes a protective gummy exudate which hardens naturelly upon exposure to air. These tears are collected by hand and processed into commercial gum Arabic products. In terms of chemical structure, gomme Arabic est un complex polysaccharide mixture composed of galactose, arabinose, rhamnose, and glucuronic acid, containing approximately 2–3% protein. The high-molecular-weight fraction carries a negative charge in solution, playing an important role as a colloidal emulsifying stabilisant. gomme Arabic is one of the most effective and widely used naturel émulsifiants known. Commercially, gomme Arabic appears as pale white to light yellow-brown translucent lumps, granulés, or poudre, odorless and tasteless. When mixed with water, it gradually dissolves to form an acidic viscous colloid solution with a solubility of approximately 50% (W/V). It is insoluble in ethanol. The pH of a 1% aqueous solution est unpproximately 4.0–4.5, weakly acidic. It can form stable coacervates with gelatin or albumin.

gomme Arabic est reconnu comme the “king of naturel émulsifiants” and “the oldest and safest naturel gum,” holding an irreplaceable cornerstone position in the global food, pharmaceutical, and cosmetic industries. Its most outstanding core advantages lie in its excellent emulsifying and stabilizing properties, good solubility and film-forming ability, naturel safety and health attributes, and extremely wide application adaptability.

Excellent Emulsifying and Stabilizing Properties: gomme Arabic is one of the most effective and widely used naturel émulsifiants known. Its high-molecular-weight fraction carries a negative charge in solution, playing an important role as a colloidal emulsifying stabilisant. It is particularly suitable for huile-in-water (O/W) emulsion systems, widely used as an emulsifying stabilisant in emulsion flavors, preventing huile droplet aggregation and separation, extending product durée de conservation. In cola-type beverages, gomme Arabic acts as an emulsifying stabilisant, preventing the essential huile “ringing” phenomenon, making it an indispensable key ingredient in Coca-Cola, Pepsi, and other global brand beverages.
