摘要
目的测定暗色等刺参的主要营养成分,评价其营养价值。方法分别采用凯氏定氮法、高温灼烧法、亚甲基蓝比色法测定海参中的粗蛋白、灰分、海参多糖含量,采用氨基酸自动分析仪测定氨基酸组成,采用电感耦合等离子体质谱法测定常量、微量无机元素。结果暗色等刺参的海参多糖含量为8.04%,蛋白质含量高达83.35%,且氨基酸组成丰富,其中甘氨酸、谷氨酸、丙氨酸含量相对较高。暗色等刺参富含人体所需的多种矿物质元素,常量元素中Ca、Mg含量较高,微量元素中Fe、Zn的含量较高。结论暗色等刺参富含蛋白质、海参多糖以及人体所需的无机元素,具有较高的食用价值和开发利用前景。
Objective To evaluate the main nutrients of Isostichopus fuscus(I.fuscus)and analyze the its nutritional value.Methods The crude protein content was determined by Kjeldahl method,the ash content was determined by high temperature burning method,the mucopolysaccharide content was determined by methylene blue colorimetric method,amino acid composition was analyzed by automatic method and the content of major and trace mineral elements was determined by inductively coupled plasma mass spectrometry(ICP-MS).Results The polysaccharide content of I.fuscus was 8.04%.The protein content of I.fuscus was 83.35%,which meaned high quality protein source.I.fuscus was rich in amino acids,and the content of glycine,glutamic acid and alanine was relatively high.It was rich in a variety of mineral elements required by the human body.The content of Ca and Mg in the major elements and the content of Fe and Zn in the trace elements was high.Conclusion I.fuscus is rich in protein,polysaccharides and inorganic elements needed by human body,which has high edible value and development and utilization prospect.
