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.

Abstract: Provided is a starch film-forming composition, comprising: A, a first gelling agent; B, starch; C, a plasticizer; D, water; wherein the first gelling agent is a gellan gum with two gel temperatures, wherein the first gel temperature is 51 to 75° C. and the second gel temperature is 40° C. to 50° C. The present application relates to the field of food or pharmaceutical raw materials. The composition is obviously superior to the prior art in terms of rubber strength, toughness and forming bonding when used in preparation of soft capsules, can fully meet the requirements for industrial production of soft capsules and can be used as an alternative in soft capsule technology.
