A method of coating substrates such as pharmaceutical tablets, food and confectionery forms, agricultural seeds and the like with a protective film comprises the steps of mixing a cellulose polymer, maltodextrin, and a plasticizer in l water to form an aqueous coating suspension, spraying an effective amount of said coating suspension on said substrates to form a film coating on said substrates, and drying the film coating on said substrates. A release agent, a secondary film former, a flow aid and / or a colorant can optionally be dispersed in the coating suspension before application of the latter to the substrates. A dry powder edible film coating composition for use in pharmaceuticals, food and confectionery forms, agricultural seeds and the like comprises a dry blend of a cellulose polymer, maltodextrin and a plasticizer. The dry coating composition may optionally include a release agent, a secondary film former, a flowability aid and / or a colorant. |
