A matrix material containing sugars and/or sugar alcohols serves to encapsulate solid or liquid substances, in particular pharmaceutically active substances and/or at least one pharmaceutically admitted flavor and the like. The material contains a substance that during cooling from its melt largely suppresses crystallization of the melt. The substance can be, for example, an inner ester of a hydroxy acid, particularly gluconic acid delta-lactone. The suppression of crystallization can be achieved by adding a small amount of a pharmaceutically admitted, and preferably weak, acid, such as lactic acid or malic acid, that simultaneously reduces the risk of saponification by alkaline components of an effervescent system that might be present. |
