摘要:

分别采用酸水解法与碱水解法测定白斑狗鱼(Esox lucius)的肌肉氨基酸含量,分析其氨基酸的种类与比例,并对其营养成分进行评价。结果表明:白斑狗鱼蛋白质中含有18 种氨基酸,总含量(以干质量计)为82.65g/100g,其中8 种为人体必需氨基酸,总含量43.58g/100g,占氨基酸总含量的53%;其必需氨基酸的构成比例基本符合食品法典委员会(FAO/WHO)的标准,氨基酸比值系数分为86.41,4 种鲜味氨基酸总含量为30.51g/100g。

关键词: 白斑狗鱼, 氨基酸, 营养成分

Abstract:

In order to evaluate the nutritional quality of Esox lucius muscle, its amino acid composition was determined and analyzed using an automatic amino acid analyzer. The amino acid composition of Esox lucius muscle consisted of 18 common amino acids including 8 essential amino acids that are required in human body. The total content of amino acids in a dried muscle sample was 82.65 g/100g and the content of essential amino acids was 43.58 g/100g. The ratio between essential amino acids and total amino acids was 53 %. The essential amino acid composition in Esox lucius muscle basically met the requirements of the food standard issued by FAO/WHO. The coefficient of amino acids ratio was 86.41. The content of four delicious amino acids in a dried muscle sample was 30.51 g/100g.

Key words: Esox lucius, amino acid, nutritional composition
