中文摘要 | 烏龍茶(番庄)為本省桃竹苗茶區特有之高品質茶,以往皆以手採茶菁製造,本 試驗利用剪採茶菁試製烏龍茶,結果顯示剪採茶菁由於茶芽切口多及破碎葉多,在日光萎凋 及室內靜置攪拌過程中,茶菁含水量減少較手採者迅速且多,二者相差約5%左右;成茶折 造率剪採與手採茶菁相差不大,分別為26.4%及26.1%,唯粗製茶精製後,剪採茶菁之梗與 老葉及茶角約佔25%,而手採者約13%,兩者差將近一倍,至於精製後之容積率,剪採茶菁 製成者每1000立方公分可含納142.7克,手採者117.9克,兩者呈顯著差異;製茶品質以手 採者為佳,剪採茶菁滋味略帶苦澀,同時外觀亦遜於手採茶菁,唯剪採茶菁仍具烏龍茶特殊 風味,由此試驗結果顯示,利用剪採茶菁製造烏龍茶在理論與技術上應為可行,本試驗可提 供利用剪採茶菁製造烏龍茶方法之參考 |
英文摘要 | In Taiwan, Oolong tea used to be manufactured from hand-plucked tea leaves. Because of industrialization of the nation has made labour supply in shortage, resulting in high production cost of the tea. The objective of this study was to investigate the application of mechanically plucked tea leaves for making Oolong tea. The optimum condition of solar and indoor withering, and machine-rolling were also studied. There was significantly different on moisture loss during solar withering and indoor withering with shaking steps between hand-plucked and mechanically plucked tea flush. Mechanically plucked tea flush with much more broken leaves and buds showed higher decrease of moisture content than hand-plucked tea leaves. A yield of 26.4% and 26.1% of made tea was produced from machine-plucked and hand-plucked tea flush respectively. A high ratio of stalk and old tea flush respectively. A high ratio of stalk and old tea leaves was observed in made Oolong tea using machine-plucked tea flush than hand-plucked. Oolong tea produced from hand-plucked tea leaves had better appearance and low bulk density. As for the tea tasting quality, the tea made from hand-plucked tea leaves was better than that of tea made from machine-plucked tea leaves. |
