To extend the shelf-life of water dropwort (Oenanthe stolonifera DC.) after harvest, we investigated the effect of modified atmosphere packaging (MAP) and precooling on quality of water dropwort during storage. In case of film package, there was no weight loss during storage, but in case of non-package, remarkably higher weight loss occurred as storage period extended. Film-packaged group after precooling had higher content of vitamin C and total chlorophyll than non-pre-cooled and non-packaged. Among the film materials, polypropylene (PP) film packaging showed a little higher content of CO₂ and C₂H₄ than low density polyethylene (LDPE) film packaging. In terms of freshness of water dropwort, we suggested that the shelf-life by PP film packaging after precooling was 12 days and that by LDPE film packing was 9 days, but that by non-package was 3-6 days.
