In this study, in order to reduce the loss of agricultural product during the distribution process, the changes in the quality of ginseng and green pepper were measured while storing them by applying EPP boxes developed by the research institute and thermoelement cooling device. With regard to ginseng, the GP-40 treatment plot filled with 40% PCM in contrast to the capacity of the container was the most effective, and in the case of its hardness, it had the least amount of change on its 15th day of storage with a 11% reduction rate compared to the initial storage period. With respect to untreated control plot and green pepper stored using PCM, GP-40 filled with 40% PCM in contrast to the capacity of the container maintained the quality most effectively. With regard to hardness, because aforementioned GP-40 showed a 9% reduction rate on the 8th day of storage in contrast to the initial figure of 0.77 kgf, it was able to maintain its hardness without any significant changes (p<0.05). Even regarding the soluble solids content, it tended to significantly maintain the content compared to other treatment plots (p<0.05). Therefore, the PCM capacity of the EPP box developed by the research institute proved to be effective in maintaining the quality of ginseng and green pepper during the storage period when the quantity of PCM was set to 40% of the container.
