This study indicated that an active film from chitosan-based film
could be achieved by incorporation with GTE, as a natural antioxidant.
Addition of GTE improved mechanical, water vapor barrier
and antioxidant properties of the resulting films. These changes, as
verified by FTIR analysis, could be attributed to the interactions
between functional groups of chitosan and GTE polyphenolic
compounds. The chitosan film incorporated with GTE shows
potential to be used as an active film. Nevertheless, further studies
are required before using this film as an active packaging for food
products.
