Abstract
An edible film useful for applying a flavoring additive to a food item is disclosed. The edible film generally includes an edible carboxymethyl cellulose film-forming resin and an edible plasticizer. The carboxymethyl cellulose film-forming resin is preferably a blend of two different carboxymethyl celluloses having different molecular weights. The edible film preferably includes additional additives, for example an edible surfactant and an edible tackifier. The edible film can suitably accept a food flavoring ingredient to form a flavored film that can be used to apply a flavor to a food item.
