中文摘要: 六堡茶是有着特殊风味的后发酵茶,其香气是影响消费者选择的重要因素。该试验先采用顶空搅拌子吸附萃取(headspace stir bar sorptive extraction,HS-SBSE)技术和气相色谱-质谱联用技术分析六堡茶香气成分,通过香气相对气味活性值(relative odor activity value,ROAV)筛选出参香、枣香六堡茶关键成分。试验结果显示,六堡茶样品共鉴定出来51种挥发性香气化合物,其中参香六堡茶共鉴定出α、β-紫罗酮、雪松醇等13种关键香气成分,枣香香六堡茶共鉴定出β-紫罗酮、水杨酸甲酯、芳樟醇等15种关键香气成分。该研究为六堡茶香型的鉴定、品质调控提升、生产工艺研究提供理论数据。
Abstract:Liupao tea is a post-fermented tea with a distinct flavor,and its aroma is an important factor that affects consumer choice.In this study,the aromatic components of Liupao tea were analyzed via headspace and stir bar sorptive extraction and gas chromatography-mass spectrometry.The key components of Shenxiang and Jujube Liupao tea were screened using relative odor activity value.A total of 51 volatile aroma compounds were identified from Liupao tea samples,among which 13 key aroma components were identified from Shenxiang Liupao tea(such as α、β-rhodopone and cedarol)and 15 key aroma components were identified from Zaoxiang Liupao tea (including β-rhodopone,methyl salicylate,and linalool).This study provides theoretical data for the identification of aroma type,quality control and improvement,and production process research of Liupao tea.
