The invention relates to the production of coloring agents which are soluble in water and in aqueous vehicles. The soluble coloring agents are, in particular, organic and are especially used in the food industry. The inventive coloring agents are characterized in that they are present in a solid form mixed with an effervescent agent in a binder which is essentially composed of polyethylene glycol wherein they are previously diluted at a temperature which is higher than the fusion temperature of said binder. Preferably, the method for the production of said coloring agents involves a dry mixture of two constituents introduced in a powdery form prior to the heating of said mixture, resulting in the fusion of the binder.
L'invention concerne la fabrication de colorants solubles dans l'eau et les véhicules aqueux. Elle a pour objet des colorants solubles, dont notamment de nature organique, destinés notamment à l'industrie alimentaire, caractérisés en ce qu'ils sont présentés sous forme solide en mélange avec un agent effervescent dans un liant essentiellement constitué de polyéthylène-glycol dans lequel ils sont préalablement dilués à une température supérieure à la température de fusion dudit liant. Le procédé de fabrication de ces colorants implique de préférence un mélange à sec des deux constituants introduits sous forme pulvérulente avant un chauffage du mélange provoquant la fusion du liant.
