Abstract

Abstract: Apostichopus japonicus ( A. japonicus ), the main trade sea cucumber species, is one of Asia's top five luxury seafoods. Commercially, live seafood has a higher value than processed seafood products. A. japonicus can easily self-melt due to its lack of a protective exoskeleton, making it difficult to transport to the consumers living in inland markets. In this study, live A. japonicus were tested to determine this species-appropriate storage surroundings, time and temperature ranges that maintains the species' optimal quality during transport. The status score, water quality, and low field nuclear magnetic resonance (LF-NMR) analysis were used to evaluate the transportation effect on live sea cucumber species. Testing revealed that at 4 °C, an A. japonicus could stay in excellent condition for 6 days and in good condition for 8 days. The results indicated a combination of seawater with oxygen as most effective to maintain a quality product during storage and transportation. This research also demonstrated that LF-NMR analysis could be developed into a rapid and undamaged technique to monitor live seafood's health condition. Our research would help this high-value seafood sell to the markets of inland areas and benefit the commercial growth of the sea cucumber aquaculture industry. Highlights: An effective technique was developed for transportation of live sea cucumber. Apostichopus japonicus can remain in very good condition for 6 days during transport. Most individuals of Apostichopus japonicus remain in good condition for 8 days during transport. LF-NMR and MRI analysis was used to monitor the healthy condition of Apostichopus japonicus .
