Analysis and Evaluation of Main Nutritive Composition in the Muscle of Wild Therapon jarbua
摘要
Abstract
Nutritional components in the muscle of wild Therapon jarbua were measured and analyzed by adopting national standard method. The results showed that the average contents of moisture, crude protein, crude fat and crude mineral in the muscle were 76.69%, 19.36%, 4.34%and 1.38%, respectively. 18 kinds of amino acid were detected from the muscle. The amount of hydrolytic amino acids in the total amino acids of the muscle of the fresh weight was 18.66%, with the highest for glutamic acid (2.98%) and the lowest for tryptophan (0.10%). The content of essential amino acids (EAA) was 7.63%, which make up 40.88% of the total amino acids and 80.83% of the total nonessential amino acids (NEAA). The content of delicious amino acids (DAA) was 7.20%, accounting for 38.60%of the total amino acids. The amino acid score (AAS) in the muscle were 0.97 in average value. The chemical score Nutritional components in the muscle of wild Therapon jarbua were measured and analyzed by adopting national standard method. The results showed that the average contents of moisture, crude protein, crude fat and crude mineral in the muscle were 76.69%, 19.36%, 4.34%and 1.38%, respectively. 18 kinds of amino acid were detected from the muscle. The amount of hydrolytic amino acids in the total amino acids of the muscle of the fresh weight was 18.66%, with the highest for glutamic acid (2.98%) and the lowest for tryptophan (0.10%). The content of essential amino acids (EAA) was 7.63%, which make up 40.88% of the total amino acids and 80.83% of the total nonessential amino acids (NEAA). The content of delicious amino acids (DAA) was 7.20%, accounting for 38.60%of the total amino acids. The amino acid score (AAS) in the muscle were 0.97 in average value. The chemical score (CS ) were 0.70 in average value.Based on a nutritional evaluation that incorporated the amino acid score (AAS) and chemical score (CS), tryptophan (Trp) and Valine (Val) were identified as the first and second limiting amino acid, respectively. 15 fatty acids were found in the muscle of T. jarbua. The saturated fatty acid(SFA), monounsaturated fatty acid(MUFA), and polyunsaturated fatty acid(PUFA) was 39.38%,23.56%and35.72%, respectively. The totals contents of DHA and EPA were 32.49%. In summary, T. jarbua is a fish with higher nutritional value and richer seafood taste.关键词
