项目摘要
We made the joint羊esearch contract of two遥ears collaboration with Indian Tea Research Association (TRA) and Tocklai Tea Experimental Station (TIES). Accordingly, we performed the researches as follows:1) Investigation of the manufacturing of Darjeeling tea “Second flash"in India. At the end of May 2006, three researchers from Japan visited TTES at Tocklai, Assam and also Darjeeling in India. We, together with two researchers from TTES, visited several tea gardens in Darjeeling to see the tea manufacturing and the state of the insect擁nfestation. We also collected the tea samples at two gardens. We observed that two kinds of insects, jassid (green leaffly: Empoasca flavescens Fabr.) and thrips (Taeniothrips setiventris Bagnall), are mainly involved in the insect infestation in Darjeeling. In June 2007, Japanese researchers visited TTES. The in様aboratry breeding of the insects was performed at TTES, and the tea leaves artificially infested by the insects were prepared to analyze the effec … More ts of the infestation on the characteristic aroma formation of the tea.2) Elucidation of the characteristic aroma formation of Darjeeling tea “Second flash"produced with the insect擁nfested leaves. The samples collected at the Darjeeling tea gardens in 2006 were analyzed by GC-MS, and it was suggested that insect infestation is involved in the aroma formation such as monoterpene alcohols and hotrienol. It was also evident from the experiments in 2007that insect infestation is mainly concerned with the characteristic aroma formation. The other experiments conducted at a Japanese tea garden demonstrated that the infestation by tea green様eafhopper (a very similar insect to jassid) is involved in the formation of 2,6-dimethylocta-3,7-diene-2,6-diol.3) Attempts to develop a new manufacturing process of CTC black tea. We suggested to the TTES researchers that they should apply the concept in manufacturing Taiwan oolong tea to Indian black tea manufacturing to improve the quality of the flavor of CTC black tea. According to our suggestion, they tried the tea manufacturing with a pilot plant at TTES, and found that the additional processes of some mechanical damages on tea leaves during the withering may improve the quality of the tea flavor.

我们与印度茶叶研究协会(TRA)和托克莱茶叶试验站(TIES)签订了两个羊EAR合作的联合遥研究合同。为此,我们开展了以下研究工作:1)大吉岭茶“秒闪”在印度的生产情况调查。2006年5月底,三名来自日本的研究人员访问了印度托克莱、阿萨姆邦和大吉岭的TTES。我们和TTES的两名研究人员一起参观了大吉岭的几个茶园,参观了茶叶的制作和昆虫擁的栖息状况。我们还在两个花园采集了茶叶样品。我们观察到两种昆虫,Jassid(绿叶绿叶:Empoasca visescens Fabr.)和蓟马(Taeniothrips Setiventris Bagnall),主要参与了大吉岭地区的虫害。2007年6月,日本研究人员访问了TTES。在TTES进行了様人工流产育种,并制备了人工侵染的茶叶进行…效应分析虫害对茶叶特征香气形成的影响更大。2)大吉岭茶“二闪”香气特征形成的阐明,以昆虫擁叶片为原料。对大吉岭茶园2006年采集的样品进行了GC-MS分析,结果表明,单萜醇和三烯醇等香气物质的形成与害虫的侵染有关。从2007年的实验中也可以看出,昆虫的为害主要与特征香气的形成有关。在日本茶园进行的其他实验表明,茶绿叶蝉(様eafhop)(一种与贾西德非常相似的昆虫)的危害与2,6-二甲基-3,7-二烯-2,6-二醇的形成有关。3)试图开发一种新的四氯化碳红茶制造工艺。我们建议TTES研究人员将台湾乌龙茶的制造理念应用到印度红茶生产中,以改善CTC红茶的风味品质。根据我们的建议,他们在TTES进行了茶叶生产的中试,发现在茶叶枯萎过程中增加一些机械损伤的工艺可能会改善茶叶的品质。较少
