生晒参 红参和黑参中氨基酸成分分析及营养评价

Analysis and Nutritional Evaluation of Amino Acid Components in Sun-cured Ginseng Red Ginseng and Black Ginseng

以生晒参、红参和黑参作为研究对象,通过氨基酸自动分析仪对3种不同参中氨基酸组成进行定性和定量分析。在综合营养评价中,使用了必需氨基酸与总氨基酸的比率(EAA/TAA)、必需氨基酸与非必需氨基酸的比率(EAA/NEAA)这2个氨基酸评价指标进行评价。结果表明,3种参中均含有被检测的17种氨基酸,生晒参氨基酸总量为43370.89 ng/mg,红参氨基酸总量为28061.76 ng/mg,黑参氨基酸总量为87514.84 ng/mg,其中生晒参的EAA/TAA为0.39,EAA/NEAA为0.64,与FAD/WHO规定的优质蛋白标准最为接近。综上所述,生晒参是高药用价值的植物蛋白来源,对人参食品药品的相关方向研究与开发具有重要意义。

This article took sun-cured ginseng,red ginseng and black ginseng as the research objects,qualitative and quantitative analysis of amino acid composition in three different types of ginseng was conducted using an amino acid analyzer.In the comprehensive nutritional evaluation,two amino acid evaluation indicators were used:the ratio of essential amino acids to total amino acids(EAA/TAA)and the ratio of essential amino acids to non essential amino acids.The results indicate that all three different types of ginseng contain 17 detected amino acids,the total amount of amino acids in sun-cured ginseng was 43370.89 ng/mg,the total amount of amino acids in red ginseng was 28061.76 ng/mg and the total amount of amino acids in black ginseng was 87514.84 ng/mg,among them,the EAA/TAA of raw sun-cured ginseng was 0.39 and the EAA/NEAA was 0.64,which was closest to the high-quality protein standard specified by FAD/WHO.In summary,sun-cured ginseng was a high medicinal value source of plant protein and this experiment was of great significance for the research and development of ginseng food and medicine.
