PAGE\*MERGEFORMAT46金骏眉茶特征香气成分的鉴定及香气模拟研究摘要金骏眉茶是我国红茶正山小种的分支，品种名贵,产于福建省武夷山市。金骏眉茶外形细长如眉，圆重紧实，表层布有少量金色绒毛，进水后呈现琥珀金骏眉色，茶香带有淡淡蜜香，入口甘甜。本论文对金骏眉茶的研究内容为：首先基于HS-SPME提取金骏眉茶香气成分，分析金骏眉茶香气成分的构成；采用多种方式进行香气成分提取，研究不同条件下对金骏眉香气成分的提取影响；其次进行多种典型茶叶特征香气成分比较与香气成分研究；通过GC-0和GC-MS分析，分离出多种金骏眉的特征香味物质，通过香气遗漏重组实验，进一步验证香气物质的贡献性，得出对金骏眉茶香气最具有贡献性的物质苯乙醇；然后对金骏眉茶进行感官评价，包括花香、木香、草香、果香和酸香几方面，得出金骏眉得感官属性显着性差异最高的是花香，其次是果香，最后是草香、木香和酸香；通过将金骏眉茶应用在茶饮料加料香精和加香香精中，通过对茶饮料实验进行感官评价，对茶饮料加料加香研巧中有一定的创新和指导意义。关键词：金骏眉茶，特征香气，香气遗漏与重组，茶饮料加香ABSTRACTEyebrowteaMr.JinisabranchofChineselapsangsouchongblacktea,breedisrare,arefoundinwuyishancityinfujianprovince.Slendershape,suchaseyebroweyebrowtea,Mr.Jinroundheavycompaction,thesurfaceofclothhasasmallgoldenhairs,appearingafterwaterambercoloreyebrow,Mr.Jinhoneyteawithlightfragrant,theentranceissweet.Thisthesismainlyresearchcontentasfollows:firstofall,basedontheHSSPMEextractioneyebrowteaaromacomponents,Mr.Jinanalysisofthecompositionoftheeyebrowteaaromacomponents,theMr.JinAromacomponentsextractedwithavarietyofways,andsomeresearchunderdifferentconditionsontheinfluenceofextractingeyebrowaromacomponents;Mr.JinSecondlycomparingavarietyoftypicalcharacteristicsofteaaromacomponentsandaromacomponentsofresearch;ByGCandGC-MSanalysis0,isolatedfromavarietyofeyebrowcharacteristicsofflavorsubstances,Mr.Jinbyaromaomissionsrestructuringexperiments,furtherverifythecontributionofaromasubstancessex,itisconcludedthattheeyebrowteaaromaisoneofthemostcontributiontoMr.Jinsexualmaterial;AndsensoryevaluationwascarriedoutontheeyebrowteaMr.Jin,includingflowers,fruit,radixaucklandiae,grassandacidsweet,draweyebrowtoMr.Jinsensorypropertiesissignificantdifferenceofthehighestofflowers,followedbyfruit,finally,thegrassissweet,sweetandsoursweet;ByapplyingeyebrowMr.Jintea
