| 摘 要： | 为了测定蓝圆鲹(Decapterus maruadsi)肌肉中的营养成分,并对其营养价值进行系统的分析及合理的评价,采用国家标准生化测定方法检测蓝圆鲹肌肉中的水分、粗蛋白质、粗脂肪、粗灰分、氨基酸、脂肪酸及矿物质。结果显示,蓝圆鲹肌肉中水分含量为75.00%,粗蛋白质、粗脂肪及粗灰分的干重含量分别为79.52%、9.88%和4.16%;共检出18种氨基酸,总含量为75.24%(干重),必需氨基酸占氨基酸总含量的30.08%,谷氨酸含量最高(11.40%),主要的限制氨基酸是色氨酸和缬氨酸,必需氨基酸指数EAAI为83.32;共检出17种脂肪酸,棕榈酸含量最高(2.60%),EPA+DHA含量为2.20%;富含磷(P)、钾(K)、钙(Ca)、钠(Na)、镁(Mg)等矿物质元素,常量元素中磷的含量最高(2 193.99 mg/kg),微量元素中铁的含量最高(22.25 mg/kg)。研究表明,蓝圆鲹是高蛋白低脂肪、营养价值及经济价值均较高的优质海洋经济鱼类,具有较好的综合开发利用价值。

| Abstract: | To determine the nutritional composition of Decapterus maruadsi muscles and systematically analyze the nutritional value of Decapterus maruadsi muscles so as to give it a reasonable evaluation , the national standard biochemical assay method was applied to detect the moisture , crude protein , crude fat , crude ash , amino acids, fatty acids and minerals of the Decapterus maruadsi muscles.The results showed:The moisture content in muscles of Decapterus maruadsi was 75.00%, the dry weight content of crude protein , crude fat and crude ash were 79 .52%, 9 .88%and 4 .16%respectively .18 kinds of amino acids were detected with the total content of 75.24%(dry weight), in which the essential amino acids accounted for 30.08%of total amino acids .The content of was glutamic acid the top ( 11 .40%) .The main limiting amino acids were tryptophan and valine , and essential amino acid index ( EAAI) was 83.32.17 kinds of fatty acids were found in muscles with the top content of palmitic acid ( 2 .60%) , and the total content of EPA and DHA was 2.20%.The mineral elements were rich in muscles , such as P, K, Ca, Na, Mg, etc.The top major element of P was 2 193.99 mg/kg and the top trace element of Fe was 22.25 mg/kg.It is concluded that Decapterus maruadsi is a kind of the high quality economic fish that have high protein and low fat , high nutritional value and high economic value .It has great potential for comprehensive exploitation and utilization . |
