摘要
为探究甘肃河西走廊产区不同品种、不同区域、不同年份的葡萄酒品质差异,本研究基于电子鼻气体识别技术,利用葡萄酒中的特征香气化合物筛选出对香气物质灵敏的传感器,并进一步对各个香气化合物在传感器上进行类别归属,然后对葡萄酒进行鉴别。结果表明,不同特征香气化合物可归属到传感器W2和W7,这两根传感器可以作为判断不同葡萄酒间气味特征区别的重要媒介。葡萄酒鉴别分析中,主成分(PCA)模型能对不同品种、不同区域、不同年份的葡萄酒进行区分。电子鼻W2传感器的识别属性可作为区分美乐和赤霞珠葡萄酒的重要依据,也可鉴别新鲜葡萄酒,W2和W7传感器的识别属性可区分武威与张掖、武威与嘉峪关葡萄酒。本研究可为阐明甘肃河西走廊产区不同品种、不同区域、不同年份的葡萄酒香气特征提供参考。
This study aims to investigate the wine quality variations in terms of the grape varieties,regions,and vintages in Hexi Corridor area.The electronic nose gas recognition technology was used to select the sensitive sensor for aroma substances based on the characteristic aroma compounds in wine.Each aroma compound was further classified on the sensor for accurate identification of wine.As the results,the distinctive aroma compounds can be ascribed into sensors of W2 and W7,which served as the crucial tools for discerning variations in odor characteristics among wines.The principal component analysis(PCA)model was able to differentiate wines based on their varieties,regions,and vintages.The results demonstrated that the recognition properties of the W2 electronic nose sensor can serve as a crucial foundation for discriminating between Merlot and Cabernet Sauvignon wines.Additionally,the recognition capabilities of both W2 and W7 sensors could distinguish the Wuwei and Zhangye wines,as well as the Wuwei and Jiayuguan wines.Furthermore,the W2 sensors could be also used to identify the fresh wines.Overall,our study offers valuable insights into the aroma characteristics of wines from different grape varieties,regions,and vintages in the Hexi Corridor area.
