title: [Analysis of the nutritional components in muscle of Sinocyclocheilus grahami and S. tingi].
abstract: In this study, we investigated the nutritive composition in the muscle of Sinocyclocheilus grahami and S. tingi. The contents of crude protein in the fresh muscle of S. grahami and S. tingi can be described as being 21.7% and 20.6%, crude fat were 3.43% and 2.66%, and total amino acid were 19.23% and 17.67%, respectively. Essential amino acids accounted for 44.08% and 43.69% of total amino acids of S. grahami and S. tingi, respectively. The values of essential amino acid index (EAAI) of the two species were 70.00% and 65.99%, respectively, with S. grahami being better than S. tingi. Ultimately, the amino acid composition of S. grahami and S. tingi muscle tissue met the standards of the Food and Agriculture Organization of the United Nations as well as those of the World Health Organization (FAO/WHO). According to the nutritive evaluation in amino acid score (AAS), the first limited amino acids of both fish were cystine+methionine. Compared with other commercial fish, the nutrition value of the muscle of Sinocyclocheilus fish can generally be considered as being better.
