    Abstract Aroma and oxygen-barrier properties of chitosan-coated papers were measured in order to evaluate the potential of these materials as biodegradable materials for food packaging. Firstly, two chitosans (Chi- 244 and Chi-652) were studied according to their ultimate biodegradability. Chi-652 showed the best fi nal biodegradation rate and was then used for subsequent tests in association with papers. Then, oxygen-barrier and aroma-barrier properties of papers, Chi-652 fi lms and Chi-652-coated papers were investigated. The Chi-652 fi lms exhibited oxygen-barrier at low relative humidity and aroma-barrier comparable to synthetic materials already used in the packaged food industry. More >
