摘要: 为了研究广东地方红茶香气物质并确定主要呈香特征,本研究采用顶空固相微萃取方法结合气质联用技术准确地鉴定了红茶样品中香气物质种类及其对总体香气的贡献。结果表明,研究鉴定了50多种香气化合物,主要包含醇类、酯类、醛类、酮类和烯类、烷烃类等,其中醇类是最主要的物质,其次是酯类和醛类。所体现的花香、甜香、果香是广东红茶的香气特征。香气化合物中芳樟醇、橙花醇、水杨酸甲酯、氧化芳樟醇、壬醛是五种最主要的呈香物质,平均含量分别占总香气的37.55%、11.90%、8.89%、5.4%和5.21%。英德系列红茶中醇类物质最多;白毛系列红茶中醛类、酮类物质最多;烯类物质以单丛和福建系列红茶含量较高。

Abstract: For the purpose of studying the volatile aroma components in Guangdong black tea and determine the main aroma components, the headspace solid-phase micro-extraction method and gas chromatography-mass spectrometry were used to determine the aroma compounds in black tea samples and their contribution to the total aroma. Results showed that more than 50 aroma compounds were identified including alcohol, ester, aldehyde, ketone, terpene, hydrocarbon etc., among which the alcohol was the most important compounds and ester and aldehyde were next to flower-like, fruit-like, refreshing and sweet aroma were the main character of Guangdong black tea. Linalool, gerariol, methyl salicylate, linalool oxide and nonanal were the five most important compounds, representing 37.55%, 11.90%, 8.89%, 5.4% and 5.21% of the total aroma respectively. The alcohol was the most important compounds in Yingde tea population, the contents of aldehyde and ketone were more in Baimao tea population. Dancong and Fujian tea plant contained more terpene compounds.
