Chitosan, a high molecularweight cationic polysaccharide, produced
by the deacetylation of chitin, iswidely used in phenolic preservation of
some fruits, such as pomegranate, litchi and raspberries because of
its excellent film forming and anti-fungal, bio-safe and biochemical
properties . Recently, these properties of chitosan
have been improved by incorporation of essential oils into chitosan
films or coatings. Incorporation of essential oils into chitosan films or
coatings can not only increase the film's antimicrobial and antioxidant
properties but also decrease water vapor permeability and retard lipid
oxidation of the product on which the film is used
