US Patent 7678397 Edible dissolving gelatin strips

Orally disintegrating or dissolving edible strips for use as a matrix for retaining and delivering nutrients, flavors and medicinal compounds are made from new liquid film casting compositions comprising a major proportion of gelatin. The particularly low melting range for hydrated gelatin produces films that leave virtually no residue upon dissolving in the mouth and can be used in the form of thicker films and strips than known edible films.
