This study was to examine the effect of the opening ratio (area of spite hole/total surface area) of plastic container and storage temperature on physicochemical changes of fresh ginseng. At room temperature (19~23℃, RH 40~61%), fungi and spoilage were observed 4 and 10 days, respectively after storing the fresh ginseng in a closed container. In storage container with 1 % opening ratio, fungi appeared 8 days after storage. In the container with 5% and 10% opening ratio, fresh ginseng showed excessive loss of moisture on the surface only after 4 days. The weight loss was most remarkable in the container with 5 and 10% opening ratio. Content of maltose and sucrose decreased gradually in accordance with storage time but the extent of decreasing ratio was less significant in the container with lower opening ratio. At low temperature (4~9℃, RH 72~92%), no fungi but 10% loss of weight was observed in the container with 5% and 10% opening ratio after 12 days storage. But in the tightly closed container and 1% opening ratio for spiling, fresh ginseng showed good appearance even after 30 days of storage. Free sugars, especially maltose revealed gradual decrease but sucrose gradually increase following decrease at the beginning. This result suggests that storage condition of low temperature and opening ratio of plastic box less than 1 % can extend storage span of fresh ginseng significantly.
