岭头单枞乌龙茶做青过程中芳香成分的变化研究
CHANGES IN AROMATIC CONSTITUENTS OF LINGTOU DANCONG OOLONG TEA DURING GREEN-MAKING
【摘要】 用气相色谱———质谱法分析了岭头单枞乌龙茶做青过程中香气组分的变化,结果表明:从萎凋叶→第1次摇青静置叶→第3次摇青静置叶→第5次摇青静置叶,芳香物质种类增多、精油总量增加,说明做青对岭头单枞乌龙茶香气形成起着重要的作用。
【Abstract】 Changes in aromatic constituents of Lingtou Dancong Oolong tea in the process of green-making were monitored with gas chromatography and mass spectrometry. The results showed that the number of kinds of aromatic constituents and the total amount of aromatic oils increased steadily from leaf withering to the first and second and third swaying and laying tea leaves. It is, therefore, concluded that green-making plays an important role in aroma formation in Oolong tea.
