中文摘要:
      测定分析了10尾黄斑篮子鱼的肌肉营养成分。结果表明,黄斑篮子鱼肌肉(鲜样)中水分、粗灰分、粗蛋白和粗脂肪的质量分数分别为74.52%、1.09%、19.64%和4.71%。肌肉中含有18 种氨基酸,总量为68.33%(质量分数,干样),其中8 种人体必需氨基酸(EAA)总量是30.40%,占氨基酸总量的44.48%;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。黄斑篮子鱼的限制性氨基酸为(蛋氨酸+胱氨酸)和色氨酸,必需氨基酸指数(EAAI)为61.07,4 种鲜味氨基酸(DAA)总量为24.36%(质量分数,干样)。脂肪酸中EPA与DHA质量分数分别为3.13%和18.03%,明显的高于其它几种经济鱼类;矿物元素比例合理,微量元素中锌和硒含量较丰富,表明黄斑篮子鱼具有较高的食用价值与保健作用。
英文摘要:
      Nutrient components in the muscle of Siganus oramin were investigated in this paper. Sample fish(n=10) were collected from t he South China Sea, near Qionghai city of Hainan Province in May of 2006. The ex amination results showed that the content of moisture, crude ash, crude protein and crude fat in fresh muscle of S. oramin were 74.52%, 1.09%, 19.64 % and 4.71%, respectively. Eighteen common amino acids were found in the muscle of S. oramin, including 8 essential amino acids(EAA), 2 half essential amino acids (HEAA) and 8 nonesse ntial amino acids (NEAA). In dry sample, the total content of amino acids(TAA) was 68.33%; the content of EAA,HEAA and NEAA were 30.40 %,6.40% and 31.55% respectively. Four kinds of delicious amino acids(DAA) accounted for 24.37% in dry sample; the ratio of total delicious amino acids to total amino acids (WDAA/WTAA) was 35.66%. The essential amino acids index(EAAI) was 61.07, the ratio of total essential amino acids to total amino acids (WEAA/WTAA) was 44.48%, and the ratio of total essential amino acids to total nonessential amino acids(WEAA/WNEAA) was 96.35%. It was clear that the content of the different ami no acids was stable and the constitutional rate of the essential amino acids met the Food and Agriculture Organization of the United Nations/World Health Organ ization (FAO/WHO) Standard. According to nutrition evaluation in amino acids sco re (AAS) and chemical score (CS), the first limited amino acid w as Met + Cys and the second limited amino acid was Trp. 10 saturated fatty acids (SFA), 6 mono unsaturated fatty acids (MUFA) and 9 poly unsaturated fatty acid s (PUFA) were found in the muscle of S. oramin. The contents of EPA and DHA in fatty acids were 3.13% and 18.03%, respectively, which were much higher tha n those of most fish species. The composition of mine ral elements in the muscle of S. oramin was reasonable and the t race elements such as Zn and Se were rich. In conclusion, this investigation ind icated that S. oramin is a nutritive and delicious food fish, an d it could be a potential aquaculture species.
