Abstract

A method for producing starch soft capsules comprises the following steps: preparing a mixture comprising starch, plasticizer and water, wherein more than 50 weight percent of the starch is present in the form of particles of granular starch; shaping the mixture to form a film in a shaping process; solidifying the mixture by increasing the temperature of the mixture during and/or after the shaping process by more than 5° C.; and shaping the film to form a soft capsule. Soft capsules produced by this method have starch particles bonded to one another. A device for performing this method comprises a shaping device to enable shaping of the starch material to form a film, and a heating device to perform a heat treatment to destructure the starch during and/or after the shaping. It comprises a rotary die device.
