US 12,636,256 B2 · Starch film-forming compositions and methods of their use for preparing capsule shells

Abstract

The present invention provides starch film-forming compositions and methods of their use for preparing capsule shells. The starch film-forming composition includes a gellan gum and at least one starch, wherein the total acyl content of the gellan gum ranges from 14 to 34%. The starch film-forming composition of the present invention has the advantages of desired film-forming strength and toughness, which can be applied in soft capsules to obtain soft capsules with a desired adhesive property upon formation and encapsulation property and which is free of animal-derived ingredients. The soft capsules thus are suitable for all ethnic populations in the world and can be applied globally.

Dependent claims

A starch film-forming composition comprising:

A. a first gelling agent;
and
B. a starch;
wherein the first gelling agent is a gellan gum which has a total acyl content ranging from 14% to 34%, wherein the content of glyceroyl of the gellan gum ranges from 12% to 26%, and the content of acetyl of the gellan gum ranges from 2% to 8%, the gellan gum in the starch film-forming composition has a single gelling temperature, and the weight ratio between the gellan gum having a single gelling temperature and the starch ranges from 0.02 to 0.5.
