Edible films and coatings are promising systems to be used asactive ingredient carriers. As they can be consider both apackaging and a food component, they have to fulfill specificrequirements: good sensory attributes, high barrier andmechanical properties, biochemical, physicochemical, andmicrobial stability, safety, non-polluting nature, simpletechnology and low raw material and processing cost. Theaddition of bioactive compounds and additives contributes toachieve these requirements to preserve the quality, safety andsensory properties of foods. Research efforts are focused inattempting to optimize the composition of film and coatingsmaterials in order to be well-processed and effective in real,pragmatic, everyday food systems. This short review attemptsto summarize the current state of knowledge on this subject,including general aspects, new trends and some successfulapplications.
