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. Both papers exhibited poor barrier… More >
