Abstract:

The muscle of A. hasta living in the sea area near Lianyungang was subjected to composition analysis and nutritional evaluation. The contents of moisture, crude fat, crude protein, and crude ash in the muscle of A. hasta were 76.32%, 1.52%, 18.06% and 1.23%, respectively. Eighteen common amino acids were found in the muscle of A. hasta, among which glutamic acid content was the highest (2.27%), and the ratios of total essential amino acids to total amino acids (WEAA/ WTAA) and to non-essential amino acids were 46.79% and 87.93%, respectively. According to the nutritional evaluation on amino acid score (AAS) and chemical score (CS), the first limited amino acid was tryptophan. The essential amino acid index (EAAI) was 75.95. The values of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), and eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) were 37.97%, 22.20%, and 10.20%, respectively. These results indicate that A. hasta muscle possess high nutritional value and health care function and thus, has promising prospects for further development.
