A modification method for improving the emulsifying power of gum arabic. In the method, particles of gum arabic are prevented, during a processing step, from arousing or suffering troubles such as adhesion to one another to form a candy-like mass, deposition on the vessel, drying, or scorching. Particles obtained by roughly granulating gum arabic are heated to 40~C or higher in an atmosphere having a relative humidity of 30 to 100% to thereby obtain a modified gum arabic having an excellent emulsifying power. This modified gum arabic is suitable for use as an emulsifying agent for drinks, confectionery, chewing gum, oil-based perfumes, oil-based colorants, oil-soluble vitamins, etc.

L'invention concerne un procédé de modification destiné à augmenter le pouvoir émulsifiant d'une gomme arabique. Ce procédé consiste à empêcher les particules de gomme arabique, pendant une opération de traitement, de provoquer ou de subir des phénomènes indésirables tels que l'adhésion des particules les unes aux autres, d'où la formation d'une masse de type sucre candi, le dépôt sur la cuve, le séchage ou le brûlage. Les particules obtenues par granulation grossière de gomme arabique sont chauffées à 40 ·C ou plus dans une atmosphère présentant une humidité relative comprise entre 30 et 100 % en vue d'obtenir une gomme arabique modifiée présentant un excellent pouvoir émulsifiant. Cette gomme arabique modifiée peut être utilisée comme agent émulsifiant pour boissons, confiseries, gommes à mâcher, parfums à base d'huile, colorants à base d'huile, vitamines solubles dans l'huile, etc.
