摘要: 采用顶空固相微萃取法以及GC-MS联用技术对两种不同加工工艺加工的紫娟红茶香气成分进行提取和分析比较。结果表明,采用新工艺加工的紫娟红茶中鉴定出的香气成分主要为醇类、醛类、酯类等,不同加工方法制成紫娟红茶的香气成分存在差异,其中加入摇青的工艺发酵5.0 h的红茶香气成分有芳樟醇、苯乙醛、顺式-3乙烯基乙酸酯等,采用重萎凋并发酵3.5 h的香气成分有芳樟醇、水杨酸甲酯、苯乙醛、香叶醇等。

Abstract: By using headspace solid phase microextraction and GC-MS Ed on different machining process of Zijuan black tea aroma components extraction and analysis comparison. The results showed that the aroma components identified in the new processed Zijuan black tea were mainly alcohols, aldehydes, esters, etc. The different processing method, and its aroma components also have differences, shake green technology of fermented into them 5.0 h of black tea aroma components are: linalool, benzene acetaldehyde, cis-3 vinyl acetate, etc. By heavy wilting and fermentation for 3.5 h, the aroma components of the plant were linalool, methyl salicylate, phenylacetaldehyde, geraniol and so on.

Key words: Zijuan black tea, new process, shake green, headspace solid phase microextraction, aroma components
