Abstract: The present study aimed to analyze the chemical composition and nutritional quality of aquaculture sea cucumber Apostichopus japonicus in Fujian. The content of crude protein, fat, carbohydrate and ash were determined as (83.66 ± 0.17) %, (1.36 ± 0.01) %, (1.82 ± 0.01) % and (11.42 ± 0.26) %,respectively. Compared with other global common trade sea cucumbers, A. japonicus was found to possess better quality with higher protein, lower fat and less ash content. The content of total amino acids (TAA) was (72.13 ± 2.54) %; the ratio of essential amino acids and non-essential amino acids (EAA / NEAA) was (59.41 ± 1.05) %; the ratio of essential amino acids and total amino acids (EAA / TAA) was (37.27 ± 0.41) %; the ratio of flavour amino acids and total amino acids (FAA / TAA) was (45.79 ± 0.41) %; the ratio of medical amino acids and total amino acids was (64.43 ± 0.09)%; the ratio of Lys and Arg was (0.53 ± 0.02); the essential amino acids index (EAAI) was 69.93; the amino acid content was well balanced and fit for FAO / WHO ideal model. 5 common elements and 4 trace elements were detected, among which the major element was found to be phosphorus and iron, respectively. Overall, based on the results obtained, aquaculture sea cucumber A. japonicus was found to serve as a better source of food diet and natural antioxidants.
