SOFT CAPSULE BASED ON STARCH AND A METHOD AND DEVICE FOR THE PRODUCTION THEREOF
1-16. -16. (canceled)
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.

17. A method for producing a soft capsule based on starch comprising:
shaping a mixture comprising starch to form a film wherein more than 50 weight percent of said starch in a liquid phase is present as particles of granular starch; and increasing temperature by more than 5°
C. to solidify said mixture by destructuring said granular starch thereby producing soft capsules from said film wherein said increasing temperature occurs during or after said shaping and wherein said granular starch is destructured to no more than stage 2.2 and wherein 50-60% of said granular starch is not birefringent in a polarization microscope.

35. A method for producing a soft capsule comprising:
preparing a mixture comprising; more than 40 weight percent, after subtracting plasticizer and starch, wherein more than 50 weight percent of said starch in said mixture is present as particles of granular starch; and 15-70 weight percent of a dry mixture plasticizer; 15-90 weight percent of the total mixture water; up to 50 weight percent of the dry mixture, after subtracting the plasticizer and thickener; and up to 10 weight percent of the dry mixture, after subtracting the plasticizer, carrageen and carrageenans; shaping said mixture to form a film in a shaping process; solidifying said mixture by increasing temperature of said mixture by more than 5°
C. either during or after said shaping process; and
shaping said film to form a soft capsule comprising particles of destructured starch.
