CA 2454006

It is intended to overcome disadvantages of pullulan powders produced by the conventional techniques such as undergoing separation in case of mixing with non-reducing sugars having glucose as a constituting sugar in the form of a powder and being hardly soluble in water, thereby providing a pullulan- containing powder showing an elevated dissolution speed, a process for producing the same and use thereof. This object can be achieved by developing a pullulan-containing powder comprising pullulan as the main component and containing non-reducing sugars having glucose as a constituting sugar and pullulan in a homogeneous state which is obtained by preparing a solution containing the non-reducing sugars having glucose as a constituting sugar and pullulan in a homogeneous state and then powdering and collecting the same, a process for producing the powder and its use. The above-described pullulan- containing powder is free from any fear of the separation of pullulan from the non-reducing sugar having glucose as a constituting sugar and thus shows an improved dissolution speed in water without damaging the moisture-resistance.

L'invention a pour objectif d'éliminer les inconvénients des poudres de pullulane produites selon des techniques classiques, telles que les poudres sujettes à la séparation lorsqu'elles sont mélangées à des sucres non réducteurs contenant du glucose comme sucre constituant, sous forme de poudre, difficilement solubles dans l'eau. L'invention concerne la production d'une poudre contenant du pullulane, cette poudre présentant une vitesse de dissolution élevée. Le procédé selon l'invention consiste à élaborer une poudre contenant du pullulane comme composant principal, des sucres non réducteurs contenant du glucose comme sucre constituant et du pullulane à l'état homogène, puis à moudre cette composition et à recueillir la poudre. L'invention concerne également un procédé de production associé, ainsi que l'utilisation de ladite poudre. La poudre contenant du pullulane selon l'invention ne peut en aucun cas être sujette à une séparation du pullulane des sucres non réducteurs contenant du glucose comme sucre constituant. Cette poudre présente donc une vitesse de dissolution améliorée dans l'eau, sans que cela nuise à sa résistance à l'humidité.
