Many natural biopolymers can be used in manufacturing of edible films and coatings. Gelatin, as one of those biopolymers, brings some advantages as it is readily available, relatively cheap, multifunctional, compatible, easy to use and generally recognized as safe. In this review, recent studies on gelatin based edible films and coatings, their production, applications, formulations, ingredients, mechanical strength, barrier and functional properties are reviewed
