Thus, the dual aim of this work is i) to develop stable carvacrol chitosan edible films from film forming dispersions made from three chitosan types with different molecular weight as a way to amplify their expected direct-contact antimicrobial effect against food spoilers, and ii) to evaluate to what extent the type of the chitosan employed as structural matrix affects the carvacrol release when the films are exposed to polar and non-polar food-simulating solvents
