摘    要:利用常规肌肉营养测试方法测定分析5尾中华倒刺鲃(Spinibarbus sinensis)的肌肉营养成分。结果表明,中华倒刺鲃肌肉(鲜样)中粗蛋白质量分数19.22%,粗脂肪质量分数1.96%,水分质量分数77.0%,灰分质量分数1.62%,碳水化合物质量分数0.18%。肌肉中含有17种氨基酸,总量为73.61%(质量分数,干样),其中7种人体必需氨基酸(不包括色氨酸)总量是32.26%,占氨基酸总量的43.83%;其必需氨基酸的构成比例基本符合FAO/WHO的标准。中华倒刺鲃的限制性氨基酸为(蛋氨酸 胱氨酸)、缬氨酸和(苯丙氨酸 酪氨酸),必需氨基酸指数(EAAI)为71.34,4种鲜味氨基酸总质量分数为24.22%(干样)。脂肪酸中EPA与DHA质量分数分别为0.87%、3.08%,比其他经济鱼类均高,微量元素比值合理,表明中华倒刺鲃有较高的食用价值与保健作用。

关 键 词:中华倒刺鲃  肌肉  营养成分

Abstract:Nutritional components in the muscle of Spinibarbus sinensis were tested and analyzed with routine methods.Samples of 5 pond-cultured individuals were collected from Sichuan Freshwater Fisheries Institute in March of 2004.The results showed that contents of crude protein,crude fat,moisture,ash and carbohydrates of fresh muscles were 19.22%,1.96%,77.0%,1.62% and 0.18% respectively.The composition of amino acids of muscle was 17 common amino acids and 7 essential amino acids for human needs(no analysis was made for tryptophane).In dry sample the total content of amino acids was 73.61%;the content of essential amino acids was 32.26%;the percentage of essential amino acids in total amino acids were 43.83%;the ratio of amino acids to no-essential amino acids (EAA/NEAA) was 78.02%.It was apparent that the content of the different amino acids was stable and the constitutional rate of the essential amino acids accorded with the FAO/WHO Standard,fundamentally.According to nutrition evaluation in amino acids score(AAS) and chemical score(CS),the first limited amino acid was Met+Cys,and the second limited amino acid was valine and Phe+Tyr;the essential amino acids index(EAAI) was 71.34;in dry sample the content of four kinds delicious amino acids was 24.22%.The contents of EPA and DHA in fatty acids were 0.87% and 3.08%,which were higher than some other economic fishes;the composition of trace elements of Spinibarbus sinensis was reasonable.It was indicated that Spinibarbus sinensis is one of freshwater fishes with better nutritive value and raising value,deserving exploitation and utilization.
Keywords:Spinibarbus sinensis  muscle  nutritional components
