摘    要: 对来自太湖五里湖的湖鲚(Coilia ectenes taihuensis)完成年龄鉴定、肌肉营养成分的测定和营养品质的比较。结果表明:湖鲚肌肉(鲜样)中蛋白质和脂肪含量显著高于其它常规经济鱼类。各年龄段湖鲚肌肉中均含18种氨基酸,1龄、2龄、3龄的氨基酸总量占干物质重量百分比分别是(73.32±0.12)%,(74.96±0.14)%,(75.82±0.17)%,其中必需氨基酸总量占总氨基酸百分比为(39.74±1.37)%,(40.42±2.71)%,(39.79±1.49)%,必需氨基酸指数分别为77.17,76.26,76.91,其评价标准满足FAO/WHO的要求,4种鲜味氨基酸总量占干物质重量百分比分别是(28.49±0.06)%,(28.97±0.07)%,(29.31±0.07)%;脂肪酸中EPA和DHA含量均很高,矿物元素比值合理。

Abstract:Age identification, measure of muscle nutrient content and nutritional quality comparison of Coilia ectenes taihuensis from Taihu Lake were completed The results showed that protein and fat content of C. ectenes taihuensis were relatively higher than those of others economic fishes. There were 18 kinds of amino acid in the muscle of C. ectenes taihuensis in different growth stages. The percentage of total amino acid to dry matter in the muscles of 1 year old, 2 year old and 3 year old C. ectenes taihuensis were 73.32±0.12, 74.96±0.14 and 75.82±0.17, respectively and the percentage of essential amino acid to total amino acid were 39.74±1.37, 40.42±2.71 and 39.79±1.49, respectively. The indexes of essential amino acid were 77.17, 76.26 and 76.91, respectively. The evaluation criteria of the above indexes met the requirements of FAO/WHO. There were higher EPA and DHA in C. ectenes taihuensis than those in other fishes. The ratio of mineral was relatively reasonable.
