本文研究了樱桃酒的特征香气成分,通过数理统计分析不同产地的樱桃酒与特征香气成分之间的相关性。采用顶空固相微萃取(SPME)方法对不同产地的樱桃酒进行香气萃取,通过气相色谱-质谱(GC-MS)联用技术共确定41种香气成分,通过外标法对这些香气成分进行定量,并对数据进行聚类分析(AHC)。对样品进行GC-O分析,在此基础上计算香气物质的香气活性值(OAV)。OAV≥1的物质被确定为特征香气物质,共确定15种物质为樱桃酒的关键香气组分。采用主成分分析(PCA)研究不同产地的樱桃酒与特征香气成分之间的相关性。AHC结果表明:2个区域的樱桃酒可按产地分类。PCA结果表明:不同产地的樱桃酒和不同的香气活性物质之间存在一定的相关性。
In this paper, the characteristic aroma components of cherry wine were studied. The correlation between cherry wine and characteristic aroma components in different regions was analyzed by mathematical statistics. Aroma extraction of cherry wine from different regions was performed by headspace solid-phase microextraction (SPME). A total of 41 kinds of aroma components were identified by gas chromatography-mass spectrometry (GC-MS) Quantitative, and cluster analysis of data (AHC). The samples were subjected to GC-O analysis, on the basis of which the aroma activity value (OAV) of the aroma substance was calculated. OAV ≥ 1 substances were identified as characteristic aroma substances, a total of 15 kinds of substances identified as cherry wine key aroma components. Principal component analysis (PCA) was used to study the correlation between cherry wine and characteristic aroma components in different areas. AHC results show that: 2 regions of cherry wine by origin classification. PCA results show that there is a certain correlation between cherry wine and different aroma actives in different areas.
