The invention relates to a process for decolorization of solutions of sugars, sugar alcohols and betaine. In accordance with the process, a polyaluminium chloride is added to a solution of sugar, sugar alcohol or betaine having a dry substance content of 10 to 70 % by weight and a temperature of 60 to 105 ~C in a suitable amount so as to obtain a mixture having a pH of 5.5 to 9.5, thereby precipitating the coloured substances, and the formed precipitate is separated from the solution. The invention also relates to the use of a polyaluminium chloride for decolorization of solutions of sugars, sugar alcohols and betaine.

La présente invention concerne un procédé de décoloration de solutions de sucres, d'alcools de sucre et de bétaïne. Le procédé consiste à ajouter un chlorure de polyaluminium dans une solution de sucres, d'alcools de sucre ou de bétaïne, dont la teneur pondérale en produit sec est comprise entre 10 % et 70 %, à une température comprise entre 60 ~C et 105 ~C. Le chlorure de polyaluminium est présent en une quantité suffisante pour que le pH du mélange se situe entre 5,5 et 9,5, et provoquer ainsi la précipitation des substances colorées. Le procédé consiste ensuite à séparer de la solution le précipité ainsi formé. L'invention concerne également l'utilisation d'un chlorure de polyaluminium pour la décoloration de solutions de sucres, d'alcools de sucre et de bétaïne.
