Abstract：In order to clarify characteristics of the muscle quality and nutritional composition of Selenotoca multifasciata, the contents of main nutrients including amino acids, fatty acids and some of minerals were analyzed and evaluated in 10 g of dorsal and abdominal muscles in 15 marine cultured S. multifasciata [body weight of (481.5±78.3) g]. The results showed that there were (67.50±0.20)% of moisture, (18.60±0.33)% of crude protein, (12.20±0.08)% of crude fat and (1.40±0.12)% of crude ash in muscle of S. multifasciata. The detected 17 amino acids accounted for 57.01% of the total content in dry muscle tissue, including 22.55% of essential amino acids, with the first limiting amino acid of valine (Val) and the second limiting amino acid of methionine+cystine (Met+Cys). A total of 24 fatty acids were detected, including 8 saturated fatty acids (41.43%), 7 monounsaturated fatty acids (36.29%) and 9 polyunsaturated fatty acids (22.28%). In the 8 minerals, the macronutrient potassium and the trace element zinc were abundant at 3830.00 mg/kg and 6.80 mg/kg, respectively. The findings indicated that the essential amino acid composition of S. multifasciata is reasonably balanced, and rich in fatty acids and high in minerals, and has high nutritional value, which provides a nutritional theoretical basis for the promotion of the culture and diversification of the processing and utilization of S. multifasciata.
