Considering the health tendency of the modern food tech- nology, the use of bio-based active films as packaging materials is very important. Among the known biopolymers, chitosan seems to be highly promising as additive for bio-based active films prepa- ration. This is mainly due to its unique cationic character and versatile properties. Several researchers recognize that antimicro- bial packaging is highly promising for the future improvement of food quality and preservation during processing and storage of different food materials. Thus, chitosan-based active packaging materials can be useful for preserving and extending the shelf life of foods. Moreover, chitosan is recognized as non-toxic and thus it can be consumed together with the preserved food. However, consid- ering the cost of chitosan preparation, it seems important to combine it with other films forming biopolymers such as plant and animal protein as well as polysaccharides.
