摘    要:可视化技术被引入葡萄酒香气成分数据的分析,以达到鉴别区分不同产区葡萄酒的目的。葡萄酒分析样品是2005年赤霞珠干红葡萄酒产品。5个产区是河北昌黎、新疆玛纳斯、云南弥勒、宁夏贺兰山东麓和河北沙城。香气成分用二氯甲烷连续萃取,有机相真空浓缩之后进行GC-MS分析检测。共鉴定并半定量分析出5个产区赤霞珠干红葡萄酒中68种香气成分,对原始色谱分析数据进行标准归一化处理,将信息映射到0,1]之间的灰度图空间,然后根据数据可视化原理,用Vc 构建含多种香气成分信息的二维灰度图,直观表征不同产地赤霞珠干红葡萄酒的香气成分信息。研究结果是一种反映葡萄酒化学信息的条形码技术,该技术转换葡萄酒香气成分色谱数据之后得到二维灰度图,能够良好区分不同产区的赤霞珠干红葡萄酒。

关 键 词:葡萄酒  赤霞珠  香气成分  可视化

Abstract:To classify several wines from different origins,data visualization was introduced to wine aroma compounds.Sample wines were collected from five famous wine production regions: Hebei Changli,Xinjiang Manasi,Yunnan Mile,the eastern region of Helan Mountain of Ningxia and Hebei Shacheng,China.Volatiles of wine were extracted by dichloromethane,then the collected dichloromethane was concentrated and submitted to GC-MS.Sixty eight aroma compounds were identified and semi-quantified.After standardizing and normalizing,data information was compressed in gray map space of 0 to 1.Data visualization was completed with Vc program and the gray map can express the information of wine aroma compounds.The research outcome was a bar code technology of wine chemicals.Five gray-scale maps were converted from respective data of wine aroma compounds,which can distinguish Cabernet Sauvignon dry red wines from different origins easily.
Keywords:Wine  cabernet sauvignon  aroma compounds  data visualization
