    This paper reports the findings of a study describing the production of chitosan-based edible films incorporated with different amount of Pimpinella anisum seed oil. The chitosan-aniseed oil (CAO) composite films (CS, CAO-0.5, CAO-1, and CAO-2) were characterized with FT-IR and DSC and their mechanical, optical transmittance, hydrophobicity and anti-oxidative properties were also investigated. With the increasing concentration of aniseed oil in the films, a continuous decrease was observed in tensile strength and Young’s modulus. Optical transmittance of chitosan-aniseed oil composite films in the UV-Visible region was lower than that of chitosan control film (without aniseed oil). Incorporation of aniseed oil into chitosan films enhanced antioxidant activity of films. The results suggested that chitosan-aniseed oil composite films can be used as a food packaging material.
