Packaging method and storage time play a significant role in maintaining the quality, safety, and shelf-life of food. In this study, the quality such as acid value, peroxide value, total bacterial count, color difference, and flavor of Marsupenaeus japonicus Oranda was evaluated depending on the five packaging methods (T-N, P-N, P-O₂R, P-V, and P-N₂) and storage periods. Changes of acid value and peroxide value strongly depend on the existing oxygen of headspace in the Marsupenaeus japonicus Oranda packages. Regardless of packaging methods, the change in acid value, peroxide value, microbial growth and flavor of the Marsupenaeus japonicus Oranda occurred depending on the storage time. Especially, it is identified the quality changes of Marsupenaeus japonicus Oranda stored with P-N₂ package with less oxygen contents were retarded, compared to the them with T-N packaged with high oxygen contents.
