摘 要：
Nutritional composition in muscle of tetraploid loach,diploid loach and Paramisgurnus dabryanus were determined by using conventional method.Results showed that the level of protein in muscle of tetraploid loach,diploid loach and Paramisgurnus dabryanus were 18.68%,18.69% and 18.20% respectively;while the fat were 0.796%,0.106% and 1.203% respectively.Humidity in muscle of three kinds of loach were 79.81%,79.52% and 78.40% respectively,while the ash were 0.951%,1.188% and 1.162%.Seventeen common amino acids and 9 essential amino acids were found in muscle of three kinds of loach.The total content of amino acids were 17.57%,18.11% and 17.47% respectively.The content of essential amino acids content were 7.84%,7.98% and 7.76% which accorded with the standard of FAO/WHO.The content of delicious amino acids were 6.98%,7.33% and 6.95%,respectively.The content of protein,17 common amino acids,total amino acids and essential amino acids were similar in muscle of tetraploid loach and diploid loach,but they both were higher than that in Paramisgurnus dabryanus.
