Abstract: The present invention relates to the preparation of granules and popped granules comprising functional substances, or active substances, and a carbohydrate carrier material, or matrix material, to the use of such granules, and the granules thus obtained. In the inventive preparation, a water-soluble dietary fiber is mixed with the functional substance in the presence of water or other aqueous solution, dried, and, after drying, converted in granules. The granules with improved properties thus obtained can be popped, providing popped granules with improved properties.
