The results showed that contents of crude protein, crude fat, moisture, ash and carbohydrates in muscle of S.sinensis and S.hollandi (fresh muscles) were 19.22%,18.02%; 1.96%,3.73%; 77.0%,76.5%; 1.62%,1.56% and (0.18%),0.15%, respectively. There were 17 amino acids and 7 essential amino acids for human needs in muscles of the two fish species (undetermination of tryptophane).Total contents of amino acids were 73.61% and 68.27%(in dry matter); the content of essential amino acids were 32.26% and 30.10%(in dry matter); the percentages of essential amino acids in total amino acids were 43.83% and 44.09%; ratio of essential amino acids to no-essential amino acids (EAA/NEAA) were 78.02% and 78.86% (in dry matter), respectively. Apparently, the content of the different amino acids were stable and the essential amino acids constitution accorded with the FAO/WHO Standard. According to nutrition evaluation, in the amino acids score (AAS) and chemical score (CS), the first limited amino acids the of two fish species were Met+ Cys and the second limited amino acids were valine and Phe+ Tyr; the essential amino acids index (EAAI) were 71.34 and 66.34, respectively; the content of four delicious amino acids were 24.22% and 22.59% in dry matter, respectively. There were higher EPA and DHA in S.sinensis and S.hollandi than in other economic fishes. For the two species, however, S.sinensis had better nutrition value than S.hollandi.Read More
