Nutritional components analysis and nutritive value evaluation in Epinephelus septemfasciatus muscles

Nutritional components in muscle of Epinephelus septemfasciatus were analyzed with routine methods. The results showed that contents of crude protein, crude fat and dressed fish of fresh muscles were 19.6%, 2.70% and 76.73%, respectively. The total content of amino acids was 18.33%, the content of essential amino acids was 7.59%, the percentage of essential amino acids in total amino acids was 41.40%. The five delicious amino acids accounted for 8.22% and the amount of polyunsalturated fatty (PUFA) was 32.45%. The essential amino acids index (EAAI) was 82.38. The content of EPA and DHA was 6.11% and 12.78%, respectively. It was apparent that the content of the different amino acids was stable and the corrtrition rate of the essential amino acids accorded with FAO/WHO standard. The composition of mineral and trace elements of the fish was reasonable. It was indicated that E. septemfasciatus is a fish species with better nutritive value and therefore E. septemfasciatus will be an important cultured species in t
