초록

본 연구에서는 총 5종의 T-N, P-N, P-O2R, P-V 및 P-N2 포장방법에 따른 보리새우 오란다의 산가, 과산화물가, 일반세균수, 색도 및 향 성분의 변화를 조사하였다. 산가 및 과산화물가를 분석한 결과, 질소치환 포장기법인 P-N2 포장방법을 적용한 보리새우 오란다의 산패가 가장 느리게 진행되는 것으로 확인되었다. 또한, 일반세균수 변화를 분석한 결과, P-N2 포장방법을 적용한 보리새우 오란다 내 미생물 성장속도가 감소하는 것을 확인하였다. 색도 변화를 분석한 결과, 포장방법에 따른 유의적인 차이는 크게 없지만, 저장기간이 늘어남에 따라 비효소적 갈변 반응으로 인하여 L*값은 감소하고, a*값 및 b*값은 증가하는 것을 확인하였다. 보리새우 오란다의 향 성분 분석 결과, T-N 포장방법이 적용된 보리새우 오란다의 향 성분은 저장기간에 따라 가장 크게 변화하는 것으로 확인되었다. 5종의 포장방법중, 질소치환 포장방법이 보리새우 오란다의 품질변화 속도를 효과적으로 감소시키는 것을 확인하였다.

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.
