Modified atmosphere packaging was applied to oriental melon(Cucumis melo L. var. makuwa Mak.) to extend its freshness during distribution. Gas composition and ethylene content in the film bags changed rapidly at the early stage of storage. Within 10 days, weight loss of the unpackaged increased upto 7.68% while those of the packaged remained less than 1.0% except LDPE film modified by addition of 5%(w/w) zeolite with 20 micro m thickness(20CK, 2.38%). Firmness was effectively maintained in the LDPE film modified by addition of 5%(w/w) zeolite with 40 micro m thickness(40CK) and the LDPE film with 40 micro m thickness containing ethylene absorber sachet(40LP). Peel color of the fruit changed rapidly in control and a little in 40CK. Oriental melon packages using 40CK provided better visual and sensory quality retention compared with others. Results suggested that packaging treatment such as 40CK could be used for extending freshness of oriental melon during transport period at ambient temperature.
