皖南地区出口“屯绿”香气成分研究
目的揭示屯绿香气成分特点及风味特征。方法基于顶空固相微萃取-气质联用结合主成分分析法对屯绿香气成分进行研究。结果 6个屯绿样品共鉴定出71种挥发性成分,主要包括9种醛类物质、11种醇类物质、11种酮类物质、13种烯类物质、10种烷烃类物质、3种酯类物质、14种芳香类化合物。香气成分主要集中于醛类、醇类、酮类、烷烃类、烯类,相对含量介于43.23%~67.52%。结论采用主成分分析法,共提取4个主成分,包含8种醇类成分、7种酮类成分、9种烯类成分、5种醛类成分、3种烷类成分、2种酯类。...

Bibliography: | Objective To reveal the aroma and flavor characteristics of Tunliv tea. Methods The aroma components of Tunliv tea were investigated based on headspace-solid phase microextraction-gas chromatographymass spectrometry(HS-SPME-GC/MS) combined with principal component analysis method. Results Totally 71 kinds of volatile components were identified in 6 Tunliv tea samples, mainly including 9 kinds of aldehyde, 11 kinds of alcohols, 11 kinds of ketones, 13 kinds of alkenes, 10 kinds of alkanes, 3 kinds of esters, and 14 kinds of aromatic compounds. The aroma components were mainly concentrated in aldehydes, alcohols, ketones, alkanes and alkenes, with a relative content of 43.23%~67.52%. Conclusion A total of 4 principal components were extracted by principal component analysis, including 8 kinds of alcohols, 7 kinds of ketones, 9 kinds of alkenes, 5 kinds of aldehydes, 3 kinds of alkane and 2 kinds of esters.
