Analysis and evaluation for the nutrition components of Percocypris retrodorslis muscles

The muscular nutritional content of Percocypris retrodorslis was analyzed and evaluated by conventional biochemical analysis methods. The results showed: The crude protein content and crude fat content of fresh muscle samples in P. retrodorslis were (17.80±0.33) % and (1.03±0.17) %. There were 17 amino acids in the dry samples of muscles, and the content of total amino acid contained (51.44±1.97) %, including 7 essential amino acids. The proportion of essential amino acids in P. retrodorslis samples was consistent with FAO/WHO standards. The lysine (Lys) had the highest amino acid score (AAS) and chemical score (CS) of 0.98 and 0.75, respectively. There were 11 fatty acids in the dry samples of muscles, including 4 saturated fatty acids (47.74±5.45) % and 7 unsaturated fatty acids (51.19±4.71) %. A total of 10 mineral elements were detected in P. retrodorslis samples and the proportion of these mineral elements were reasonable. According to the results, P. retrodorslis is delicious and nutritious, and has great development potential.
