摘要:
选用日照球形绿茶和日照卷曲形绿茶为研究对象,采用顶空-固相微萃取法（Head-Space Solid-Phase Micro Extraction,HS-SPME）富集其香气物质,利用气质联用（Gas Chromatography and Mass Spectrometry,GC-MS）方法进行香气成分分析。结果表明:两种绿茶香气组分类似差异不显著,两者均为栗香型绿茶,有7种共同的主要香气成分:顺-己酸-3-己烯酯、脱氢芳樟醇、β-芳樟醇、2-正戊基呋喃、2-乙烯基-1,1-二甲基-3-亚甲基-环己烷、反-β-罗勒烯、D-柠檬烯,其他香气组分几乎相同,无明显差异。因此,两种绿茶在香气组分方面差异不显著,但在外形方面日照球形绿茶优于日照卷曲形绿茶。
Abstract:
The aroma components of Rizhao pelleted green tea and Rizhao curly green tea were determined by HS- SPME / GC- MS.The results showed that the aroma components of two kinds of green tea were almost the same, and the difference was not significant. Both were green tea with chestnut- like, they had 7 common aroma components such as cis- hexanoic acid, 3- hexenyl ester, hotrienol, β- linalool, 2- pentylfuran, 2- ethenyl- 1, 1- dimethyl-3- methylene- cyclohexane, trans- β- ocimene, D- limonene and so on.Other aroma components were almost the same, the difference was not significant. Therefore, the difference of aroma components between two kinds of green tea was not significant, but Rizhao pelleted green tea was better than Rizhao curly green tea in shape.
