Abstract

The invention relates to a film-forming composition comprising a fluidised hydroxypropyl starch and sorbitol, and to a film-coating method using said composition. The invention further relates to film-coated solid forms comprising a fluidised hydroxypropyl starch and sorbitol in the coating.

Claims

1. A film-forming composition, comprising a fluidized hydroxypropyl starch and sorbitol and in that the sorbitol is included in said film-forming composition at a content of between 5% and 40% by dry weight relative to the dry weight of fluidized hydroxypropyl starch.

2. The film-forming composition as claimed in claim 1, the fluidized hydroxypropyl starch is a corn and/or legume starch.

3. The film-forming composition as claimed in claim 1, wherein the fluidized hydroxypropyl starch and the sorbitol together represent between 15% and 100% by dry weight relative to the total weight of the solids of said film-forming composition.

4. The film-forming composition as claimed in claim 1, also further comprising an antiaggregating agent.

5. The film-forming composition as claimed in claim 1, further an opacifying agent.

6. The film-forming composition as claimed in claim 1, wherein the fluidized hydroxypropyl starch is made soluble.

7. The film-forming composition as claimed in claim 1, wherein said composition is a ready-to-use product.

8. The film-forming composition as claimed in claim 1, wherein said composition is an aqueous composition.

9. The aqueous film-forming composition as claimed in claim 8, having a solids content of between 5% and 50% by weight.

10. The aqueous film-forming composition as claimed in claim 8, having a Brookfield viscosity, at 25°

C., of less than or equal to 500 mPa·

s.

13. The film-forming composition as claimed in claim 1, wherein the fluidized hydroxypropyl starch is pea starch.

14. A film-coating process, characterized in that the process comprises:

a step a′

) of spraying an aqueous film-forming composition as defined in any one of claims 8 to 10 on to a moving bed of solid forms, and

a step b) of drying the solid forms to form film-coated solid forms.

15. A film-coating process, characterized in that the process comprises:

a step a) of producing an aqueous film-coating composition comprising mixing a ready-to-use product as defined in claim 7 with water,

a step a′

) of spraying an aqueous film-forming composition obtained in step a) on to a moving bed of solid forms, and

a step b) of drying the solid forms to form film-coated solid forms.

16. The film-coating process as claimed in claim 14, characterized in that the bed of solid forms is preheated to a temperature of between 30 and 60°

C.

17. The film-coating process as claimed in claim 15, characterized in that the bed of solid forms is preheated to a temperature of between 30 and 60°

C.

11. A solid form comprising a core covered with at least one film-coating layer, wherein this film-coating layer comprises a fluidized hydroxypropyl starch and sorbitol, and in that the sorbitol is included in said film-coating layer at a content of between 5% and 40% by dry weight relative to the dry weight of fluidized hydroxypropyl starch.

12. A film, comprising a fluidized hydroxypropyl starch and sorbitol, wherein the sorbitol is included in said film at a content of between 5% and 40% by dry weight relative to the dry weight of fluidized hydroxypropyl starch.
