Abstract
The invention provides the addition of highly inhibited starch filler to gelatin-free films and soft capsules. The addition of the highly inhibited starch filler raises the solid levels during processing without substantially increasing the melt viscosity. The resultant films and capsules are transparent.
Claims18
A composition comprising:
- a) at least one highly inhibited granular starch filler, wherein said filler swells less than 150% after cooking at 95-100° C. for 30 minutes;
- b) at least one matrix starch selected from the group consisting of native starch and modified starch, wherein modified starch is modified physically, chemically and/or by hydrolysis, and wherein starches modified chemically are selected from the group consisting of hydroxyalkylated starches and succinated starches,
- and starches modified physically are modified by a method selected from extrusion, spray-drying, drum-drying, agglomeration, pregelatinization and mixtures thereof,
- wherein the matrix starch comprises from about 40 to about 95 weight percent of the total dry composition;
- and
- c) at least one plasticizer;
- wherein said composition is a film having a thickness of about 0.50 mm to about 0.65 mm, has a transparency greater than 70%.

A soft capsule shell composition comprising:
- a) a highly inhibited granular waxy rice starch filler, wherein said filler swells less than 150% after cooking at 95-100° C. for 30 minutes;
- b) a hydroxypropylated starch, wherein the starch comprises from about 40 to about 95 weight percent of the total dry composition;
- and
- c) a plasticizer;
- wherein said composition when cast as a film having a thickness of about 0.50 mm to about 0.65 mm has a transparency greater than 70%.
