Abstract: A process for shaping into a granular form a delivery system for the controlled release of flavor or fragrance compounds. This process includes the steps of preparing a mixture of a continuous phase carrier containing a volatile flavor or fragrance compound or composition finely divided therein and having a low water content. This guarantees that the glass transition temperature of the mixture is the glass transition temperature of the final product. The mixture is then heated within a screw extruder to a temperature of between 90 and 130° C. to form a molten mass, the molten mass is extruded through a die and then chopped as it exits the die. The latter step is performed at a temperature above the glass transition temperature of the carrier.
