Basic components analysis and nutritive value evaluation of Anguilla bicolor pacifica muscle

Nutritiona1 components of Anguilla bicolor pacifica muscle were analyzed with routine methods. The results showed that contents of moisture, crude protein from fresh muscles were 62.56% and 15.85%. Except Tryptophan, 17 common amino acids were detected from muscles which include 7 essential amino acids (EAA) for human body. In dry sample, the total content of amino acids (TAA) was 36.33%, the content of EAA was 13.99%. The constitutional rate of the essential amino acids accorded with the FAO/WHO standard. The main limited amino acids of A. bicolor pacifica were Methionine+Cysteine and Valine. The essential amino acids index (EAAI) was 78.26. Five kinds of delicious amino acids (DAA) accounted for 16.58% in dry sample. The content of monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) in fatty acids were 44.41% and 16.70%. The total content of EPA (C20:5n-3) and DHA (C22:6n-3) in fatty acids was 7.33%. The result showed that A. bicolor pacifica had high edible value and health effect, and would be an important cultured species in the future.
