There is increasing public interest in development of edible natural biodegradable coatings to replace thecurrently used commercial synthetic waxes for maintaining postharvest quality of citrus fruit. We testedthe efficacy of a newly developed polysaccharide-based edible bilayer coating comprising carboxymethylcellulose (CMC) and chitosan in preserving postharvest quality of various citrus fruit, including ‘Or’ and‘Mor’ mandarins, ‘Navel’ oranges, and ‘Star Ruby’ grapefruit after simulated storage and marketing. In allcitrus species, it was found that the CMC/chitosan bilayer coating was equally effective as the commer-cial polyethylene wax in enhancing fruit gloss.
