摘  要:
为研究靖安白茶的香气成分,采用顶空自动进样器对靖安白茶的挥发性成分进行提取,使用三重串联四极杆气-质联用(GC-QQQ-MS)技术对其进行鉴定。结果表明:样品在90℃平衡30min后,共分离并鉴定出37种香气成分,其中烷烃类7种、酯类6种、醇类6种、酮类6种、烯烃类4种、酸类3种、醛类2种、酚类1种,其他挥发性成分2种;香气成分中薄荷醇、柠檬烯、薄荷酮、异胡薄荷醇、壬醛、正己酸乙酯、长叶烯、芳樟醇、胡椒酮、棕榈酸的含量较高。靖安白茶香气成分主要为醇类和烯烃类,其中薄荷醇含量远高于其他组分。

摘  要:
The composition of aroma compounds in Jing'an White Tea was analyzed by headspace extraction and gas chromatography-triple quadrupole mass spectrometry(HS-GC-QQQ-MS).Results showed that a total of 37 major volatile compounds were identified,including 7 hydrocarbons,6 esters,6 alcohols,6 ketones,4 olefins,3 acids,2 aldehydes,1 phenols and 2 other compounds.Among them,menthol,limonene,menthone,isopulegol,nonanal,ethyl caproate,caryophyllene,linalool,piperitone and n-hexadecanoic acid were the major components.The main aroma components were alcohols and olefins in Jing'an White Tea,with menthol being the most abundant aroma component.
