光唇鱼与厚唇鱼肌肉营养成分的研究

目的]比较光唇鱼和厚唇鱼的肌肉营养成分与氨基酸含量。方法]对光唇鱼和厚唇鱼的肌肉营养成分进行测定,并探讨了2种鱼的营养价值。结果]光唇鱼粗蛋白含量为19.4%,高于厚唇鱼(18.9%)。光唇鱼粗脂肪含量为1.05%,比其他鱼类低,具有良好的适口性。光唇鱼氨基酸总量达13.19%,也高于厚唇鱼(13.04%)。光唇鱼的必需氨基酸总量为5.31%,而必需氨基酸的占氨基酸总量的40.27%,均高于厚唇鱼。从与鱼肉味道相关的4种鲜味氨基酸来看,光唇鱼为5.11%,也高于厚唇鱼。结论]该研究为光唇鱼和厚唇鱼的配合饲料研制和人工繁殖提供理论依据。

Study on the Nutritional Components in the Muscles of Acrossocheilus fasciatus and Acrossocheilus labiatus

Objective] The research aimed to compare the nutritional components and amino acid content in the muscles of Acrossocheilus fasciatus and Acrossocheilus labiatus.Method] The nutritional components in the muscles of A.fasciatus and A.labiatus were determined and the nutritional values of two fish varieties were discussed.Result] The content of crude protein in A.fasciatus was 19.4%,higher than that of A.labiatus(18.9%).The content of crude fat in A.fasciatus was 1.05%,lower than that in other fishes.Therefore,A.fasciatus had a good edibility.The total amount of amino acids in A.fasciatus reached 13.19%,higher than that of A.labiatus(13.04%).The amount of essential amino acids in A.fasciatus was 5.31% and the proportion of essential amino acids in total amount of amino acids was 40.27%,which were both higher than that of A.labiatus.The content of four kinds of flavor amino acids that was related to the flavour of fish in A.fasciatus was 5.11%,higher than that in A.labiatus.Conclusion] The research provided theoretical basis for the production of the compound feed and the artificial breeding of A.fasciatus and A.labiatus.
