摘要
对我国浙江、厦门和海南生产的丁香鱼干进行营养成分分析和评价,结果显示:浙江、厦门和海南产区的丁香鱼干蛋白质含量分别为45.25%、42.42%、38.95%,脂肪含量分别为4.71%、3.42%、3.05%。3个产区的丁香鱼干总氨基酸含量为34.4%～38.7%,组合比例均衡,其中含有人体所必需的各种氨基酸,蛋氨酸为第一限制氨基酸,赖氨酸含量高达3.86g/100g,鲜味氨基酸的含量占总氨基酸含量的48.23%。丁香鱼干脂肪含量较低,但富含高不饱和脂肪酸,DHA含量为21.21%～25.83%,含有丰富的Ca、P、Fe、Zn、Se等微量元素,对不同产区的丁香鱼干的重金属等有毒有害物质分析结果表明其均符合国家相关安全卫生标准,说明丁香鱼干是一种品质好,有较高营养价值的海产品。
In this study,the nutrient components in dried Engraulis japonicus from the sea areas near Zhejiang,Xiamen and Hainan were analyzed and evaluated. The results showed that protein contents in dried Engraulis japonicus from Zhejiang,Xiamen and Hainan coastal areas were 45.25%,42.42% and 38.95%,and fat contents were 4.71%,3.42% and 3.05%,respectively. Dried Engraulis japonicus from the three sea areas exhibited a proportional balance in total content of amino acids in the range of 34.4% to 38.7%. All essential amino acids essential for human body were contained in dried Engraulis japonicus from the three sea areas,and methionine acted the first limited amino acid,and lysine content was up to 3.86 g/100 g and flavor amino acids represented 48.23% of the total amount of amino acids. Dried Engraulis japonicus was low in fat but rich in polyunsaturated fatty acids,especially DHA,of which the content was between 21.21% and 25.83%,and Ca,P,Fe,Zn,Se and other trace elements. The detection and analysis of heavy metal elements and other toxic substances in dried Engraulis japonicus indicated that all the dried products from these three coastal areas met national safety and health standards. Therefore,dried Engraulis japonicus is a kind of marine product with good quality and high nutritional value.
