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.
在本研究中，我们调查了滇池金线鲃和抚仙金线鲃肌肉中的营养成分。滇池金线鲃和抚仙金线鲃新鲜肌肉中的粗蛋白含量分别为21.7%和20.6%，粗脂肪含量分别为3.43%和2.66%，总氨基酸含量分别为19.23%和17.67%。必需氨基酸分别占滇池金线鲃和抚仙金线鲃总氨基酸的44.08%和43.69%。这两个物种的必需氨基酸指数（EAAI）值分别为70.00%和65.99%，滇池金线鲃优于抚仙金线鲃。最终，滇池金线鲃和抚仙金线鲃肌肉组织的氨基酸组成符合联合国粮食及农业组织以及世界卫生组织（FAO/WHO）的标准。根据氨基酸评分（AAS）的营养评价，这两种鱼的第一限制氨基酸均为胱氨酸+蛋氨酸。与其他商业鱼类相比，金线鲃属鱼类肌肉的营养价值总体上可被认为更好。
