Soft capsule based on starch and a method and device for the production thereof

摘要

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.

1. A method for producing a soft capsule based on starch comprising:
shaping a mixture comprising starch to form a film wherein in said mixture more than 50 weight percent of said starch is present as particles of granular starch in a liquid phase in which granular starch is destructured at most up to stage 1.2; and increasing temperature to solidify said mixture by destructuring said granular starch thereby producing soft capsules from said film wherein said increasing temperature occurs during and/or after said shaping; wherein 5-10% of the starch grains are not birefringent in a polarization microscope in stage 1.2.
