Abstract

Abstract Food waste is one of the major challenges in food safety and finding a solution for this issue is critically important. Herein, edible films and coatings became attractive for scientists as they can keep food from spoilage. Edible films and coatings can effectively preserve the original quality of food and extend its shelf life. Polysaccharides, including starch and cellulose derivatives, chitosan, alginate and pectin, have been extensively studied as biopackaging materials. One of the most interesting polysaccharides is alginate, which has been used to make edible films and coatings. Incorporating essential oils (EO) in alginate matrices results in an improvement in some properties of the edible packages, such as antioxidant and antimicrobial properties. Additionally, the use of nanotechnology can improve the desirable properties of edible films and coatings. In this article we reviewed the antimicrobial and antioxidant properties of alginate coatings and films and their use in various food products.
