贵人香葡萄酒氨基酸含量对产地特征性贡献的分析

Analysis of primary amino acids profiles of Italian Riesling white wines and their contribution to regional characteristics

摘要: 以张裕3大产区的16款贵人香葡萄原酒为实验样本,通过反相高效液相色谱法技术对其中的17种主要的游离氨基酸和总氨基酸进行了定性定量分析,并以17种氨基酸的含量作为参数进行主成分分析和聚类分析。结果表明,样品中17种氨基酸均能被检测到,其中不论是游离氨基酸还是总氨基酸,均为精氨酸、脯氨酸含量最多,约占氨基酸总量的40%～70%;通过主成分分析与聚类分析,可以看出不同产区的贵人香葡萄原酒在游离氨基酸和总氨基酸含量上都具有较为明显的产地特征性。

Abstract: Sixteen Italian Riesling white wines from three regional regions provided by YanTai ChangYu Pioneer Wine Company Limited have been analyzed for primary free and total amino acids by reversed-phase high performance liquid chromatography.The date were processed by principal componet analysis (PCA) and cluster analysis (CA) .The results showed that 17 amino acids were qualitied and quantitied in Italian Riesling white wines and as the most abundant amino acids, Arginine and Proline are accounts for 40% to 70% of the total amino acids content.From the results of PCA and CA, significant regional characteristics were observed in both free and total amimo acids content of Italian Riesling.
