摘　　要：对舌虾虎鱼的肌肉营养成分进行了分析,并对其营养品质进行了评价。结果表明,舌虾虎鱼肌肉(鲜样)中水分、粗蛋白、粗脂肪和粗灰分的质量分数分别为79.92%±0.96%、16.76%±0.30%、0.91%±0.07%和2.25%±0.14%。肌肉中含有18种氨基酸,总量为78.70%±0.57%(质量分数,干样),其中8种必需氨基酸(EAA)总量是32.26%±0.55%,占氨基酸总量的40.99%,其必需氨基酸的构成比例符合联合国粮农组织/世界卫生组织(FAO/WHO)的标准。舌虾虎鱼的第一限制性氨基酸为色氨酸,第二限制性氨基酸为(蛋氨酸+胱氨酸),必需氨基酸指数(EAAI)为63.88,4种鲜味氨基酸(DAA)总量为29.67%±0.30%(质量分数,干样)。脂肪酸中EPA与DHA质量分数分别为3.91%±0.11%和8.10%±0.60%,明显高于其它几种淡水经济鱼类。研究表明,舌虾虎鱼含有丰富的氨基酸和脂肪酸营养,具有较好的食用价值与保健作用。In order to understand the nutritive quality and nutrient components in the muscle of Glossogobius giuris and to evaluate the potential of the species as a diet source for Chinese sturgeon that is an endangered species only found in the coastal China Seas and the Yangtze River,the main nutrient components in the muscle of G.giuris were analyzed in this paper.Samples[body weight,（9.07 ± 1.87） g;body length,（8.17 ± 0.63） cm]were collected in the coastal area of Zhejiang Province.Analysis methods of nutrient components were based on the standards of GB 5009-85 and BT/T 14965-1994.Evaluation standards of the nutritive quality were based on the FAO/WHO＇s standard mode.The general nutrient compositions were determined with routine methods.Amino acid compositions were determined with amino acid analyzer.Fatty acid compositions were inspected with GC.The results showed that the content of moisture,crude protein,crude fat and crude ash in fresh muscle of G.giuris were 79.92% ± 0.96%,16.76% ± 0.30%,0.91% ± 0.07% and 2.25% ± 0.14% respectively.Eighteen common amino acids were found in the muscle of G.giuris including 8 kinds of essential amino acids（Thr,Val,Met,Phe,Ile,Leu,Lys and Trp）,2 kinds of half-essential amino acid（His and Arg）,8 kinds of nonessential amino acids（Asp,Glu,Ser,Gly,Ala,Tyr,Cys and Pro）.In dry sample,the total content of amino acids（TAA） was 78.70% ± 0.57% ;the contents of EAA,HEAA and NEAA were 32.26% ± 0.55%,7.55% ± 0.09% and 38.88% ± 0.34% respectively.Four kinds of delicious amino acids（DAA） accounted for 29.67% ± 0.30% in dry sample;the ratio of total delicious amino acids to total amino acids（WDAA /WTAA） was 37.70%.The essential amino acids index（EAAI） was 63.88,the ratio of total essential amino acids to total amino acids（WEAA /WTAA） was 40.99%,and the ratio of total essential amino acids to total nonessential amino acids（WEAA /WNEAA） was 82.96%.It was clear that the content of the different amino acids was stable and the constitutional rate
