Abstract
Disclosed herein are composition comprising a modified starch and a carrageenan, especially iota-carrageenan, where the compositions are suitable for use in manufacturing soft capsules.
Claims22
A dried film composition suitable for soft capsules the composition consisting essentially of from 42-84% by weight gel formers comprising a mixture of iota-carrageenan and modified starch;
- water;
- a plasticizer, aid a buffer, wherein said iota-carrageenan and said modified starch are at a weight ratio of at least 1.5:1.
A composition suitable for forming a soft capsule, the composition comprising iota-carrageenan and at least one modified starch selected from the group consisting of hydroxypropylated tapioca starch, hydroxypropylated maize starch, acid thinned hydroxypropylated corn starch, potato starch, pregelatinized modified corn starches, and wherein said starch has a hydration temperature below about 90° C. and wherein the weight ratio of modified starch to iota-carrageenan ranges from 1.5:1 to 4.0:1.
A composition suitable for forming a wet film for encapsulating materials, the composition comprising a modified starch selected from the group consisting of native potato starch, pre-gelatinized modified corn starch, pre-gelatinized acid thinned modified corn starch, acid modified hydroxypropylated corn starch, flash dried acid modified native corn dent starch, hydroxypropylated acid modified tapioca starch, maltins, modified corn starch and modified high amylose corn starch, and iota-catrageenan in a ratio by weight of at least 1:5:1;
- said film capable of fusion under apressure of at least about 207 kPa (30 psi).
