摘要
为探究福建省诏安湾不同站位牡蛎营养价值及差异,本研究对诏安湾5个不同站位的牡蛎的基本营养成分、氨基酸、矿物质和脂肪酸组成含量进行测定,并分析评价其营养成分及差异。结果显示,诏安湾5个站位牡蛎的粗蛋白含量很高,以田厝站位最高;各站位牡蛎均检测出18种氨基酸,包括8种必需氨基酸和10种非必需氨基酸,峰琦站位牡蛎的氨基酸总含量最高,其呈味氨基酸也显著高于其他4个站位,FAO/WHO氨基酸评分也最高。5个站位牡蛎矿物质元素含量丰富,其中峰琦站位的Fe、Zn、Mn、Mg、K、Na和P含量最高;赤石湾站位的Cu、Se含量最高;南门站位的Ca含量最高。5个站位牡蛎均检出14种脂肪酸、9种不饱和脂肪酸,不饱和脂肪酸的含量很高,尤其是ω-3系列,其中寮雅站位牡蛎的脂肪酸和牛磺酸含量最高。
To explore the nutritional value and difference of oyster in different stations of Zhao'an Bay of Fujian Province,the contents of basic nutritional component,amino acids,minerals,and fatty acids of Crassostre angulata in 5 different stations of Zhao'an Bay were analyzed.The results showed that the contents of protein in 5 stations of of Zhao'an Bay were all high,especially in Tiancuo station which was the highest in the content of protein.18 kinds of amino acids were detected in these samples,among which there were 8 kinds of essential amino acids and 10 kinds of nonessential amino acids.The total content of amino acids in the oyster of Fengqi station was the highest,while the content of flavor amino acid and the FAO/WHO amino acid score were significantly higher than the other 4 stations.The mineral elements contents were rich in Zhao'an Bay and varied among 5 stations.The contents of Fe、Zn、Mn、Mg、K、Na and P in Fengqi station,the contents of Cu and Se in Chishiwan station,and the contents of Ca in Nanmen station were the highest.14 kinds of fatty acids were detected in 5 stations,including 9 kinds of unsaturated fatty acid with rich content,especially theω-3 polyunsaturated fatty acid.The content of fatty acid and taurine of oyster in Liaoya station were higher than the other 4 stations.
