Abstract BACKGROUND Deep sea growth sea cucumber ( Stichopus japonicus ) ( DSG‐SC ) is considered a most nutritious and luxurious seafood in Asia. This study compared the proximate composition and nutritional quality of collagen, polysaccharides, amino acids ( AAs ) and fatty acids ( FAs ) in DSG‐SCs from different origins. RESULTS The contents of protein, ash, carbohydrate, fat, collagen, saturated fatty acids ( SFAs ), monounsaturated fatty acids ( MUFAs ), polyunsaturated fatty acids ( PUFAs ), total amino acids ( TAAs ), essential amino acids ( EAAs ), fucose and uronic acid differed among the origins. DSG‐SC of Dalian origin had lower contents of ash, fat, uronic acid, TAAs and EAAs but higher contents of protein, collagen, PUFAs , eicosapentaenoic acid ( EPA ), docosahexaenoic acid ( DHA ) and fucose compared with the other origins. DSG‐SCs had a higher proportion of PUFAs and were richer in polysaccharides than other seafood. Glutamate and glycine were the dominant AAs , while leucine and threonine were the most abundant EAAs . CONCLUSION DSG‐SCs are a good source of collagen, polysaccharides (especially fucose), EAAs (especially leucine and threonine) and PUFAs (especially EPA and DHA ). Dalian seems to be a promising origin to produce high‐value sea cucumber with high PUFA , fucose, collagen and protein contents. © 2015 Society of Chemical Industry
