Abstract
A method of preparing an extract of at least one active principle in the form of completely dry soluble granules wherein an extract of an active principle is prepared in a solvent medium and depositing the extract upon the internal and external walls of microporous carriers that are insoluble in the solvent, drying the impregnated granules, and coating the walls of the granules with a film forming polymer. The granules are a soluble dietary fiber based upon a polymer selected from the group comprising inulin and oligofructoses and, fructo-oligosaccharides separately or mixed.

A method for the preparation of an extract of at least one active component in the form of completely soluble dry granules, which comprises:
- preparing an extract of an active component in a solvent medium;
- depositing said extract by wet granulation on the internal and external walls of a microporous carrier which is insoluble in said solvent medium, with said microporous carrier being in the form of microgranules made of a dietary fiber based on a polymer selected from the group consisting of any one of inulin, oligofructoses, and fructooligosaccharides, and mixtures thereof, and having a specific surface area of at least about 0.5 m2/g;
- drying the impregnated granular carrier;
- and
- then coating the impregnated walls of the microporous carrier with a film-forming polymer.
