Oxygen has a deleterious effect on the quality of a wide variety of food products. The application of edible
films and coatings to food products represents a new approach to solve this problem. Edible films and coatings
can include antioxidant agents in their formulation and at the same time, they represent a barrier to
oxygen, which results in a better preservation of quality. The water activity of the product, as well as the
ambient relative humidity, determines the antioxidant effect of films and coatings. This paper reviews
the latest studies dealing with the effectiveness and application of antioxidant films and coatings
