Abstract:

Nutrient components in muscle of Semilabeo prochilus were analyzed and the nutritive quality of the meat were
evaluated in this study. The results showed that the ratio of flesh to body mass was (70.90 ± 3.20)%. Semilabeo prochilus
muscle contained (75.62 ± 1.17)% moisture, (20.04 ± 0.78)% crude protein, (3.67 ± 0.08)% crude fat and (1.34 ± 0.13)%
ash. A total of 18 amino acids were detected in muscle proteins, including the 8 essential amino acids. In dry sample, the
total content of amino acids was (79.83 ± 0.59)%. The content of essential amino acids was (33.95 ± 0.15)%. Five delicious
amino acids accounted for (35.69 ± 0.24)% of the total amino acids. Glu was the most abundant and Tyr was the least
abundant amino acid in Semilabeo prochilus muscle. The percentage of essential amino acids in total amino acids (EAA/
TAA) was 42.53%. The constitutional ratio of essential amino acids met the FAO/WHO standard. Amino acid score (AAS)
and chemical score (CS) analyses showed that the primary and secondary limited amino acid in Semilabeo prochilus muscle
were Try and Val, respectively. The essential amino acid index (EAAI) was 62.08. The contents of monounsaturated fatty
acids (MUFA), polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were
(45.33 ± 0.08)%, (26.04 ± 0.19)%, (4.75 ± 0.04)% and (7.35 ± 0.03)%, respectively. These results indicated that Semilabeo
prochilus was a fresh water fish with high nutritive value.
