Abstract:In order to explore the manufacturing suitability for Zijuan tea,the aroma components of Zijuan black tea were extracted by fully automated HS-SPME,and were identified by GC-MS.Then comparison of the aromatic components and contents between Dianhong tea was made.The results showed that 83 kinds of aroma components were identified in Zijuan black tea and 82 kinds in Dianhong tea,alcohol was the major aromatic components in these two kinds of tea,representing 44.42% and 44.99% of the total peak area respectively.The major aromatic compounds of Zijuan black tea were linalool,linalool oxide,phytol,caffeine,6,10,14-trimethyl-2-pentadecanone,hexadecanoic acid and geraniol,respectively,while the major aromatic compounds of Dianhong tea were linalool,hexadecanoic acid,linalool oxide,phytol,geraniol,caffeine and methyl salicylate.The aromatic components in these two kinds of tea were found very similar and 77 of them were identical,the contents of aldehydes,esters and acids compounds in Zijuan black tea were lower than that in Dianhong tea,but the contents of other compounds are higher than Dianhong tea.
