中文摘要 | 本試驗目的在探討大葉種臺茶八號茶菁原料對製成綠茶的兒茶素含量及品質之 影響,綜合採摘茶季、採摘葉齡、採摘葉數、葉面施肥等面向考量,藉以建立高EGCG 茶類產製技術,進而生產改善綠茶品質又可保留高EGCG 含量之茶類。由試驗結果 顯示,臺茶八號以2-3 或3-4 葉齡採摘,以及手採一心二葉或3-4 葉齡機採之茶菁原 料,能夠兼顧產量、綠茶品質及EGCG 含量,而且有無葉面施肥影響不大,可以做 為高EGCG 茶類產製技術之参考依據。 |
英文摘要 | The study was conducted to investigate the effect of tea leaf materials on the catechins content and quality of green tea made from TTES No.8. By tea season, leaf age, leaf number of plucking and foliar fertilization, in order to establish a high EGCG tea production and manufacturing technology, thus improving the quality of green tea, but also retains high EGCG content. The experimental results show that TTES No.8 of large-leafed cultivar plucked with 2-3 or 3-4 leaf age, tea leaf materials of hand-plucking as one bud two leaves, 3-4 leaf age mechanical plucking, can maintain yield, quality of green tea and higher EGCG content, and foliar fertilization had no obvious effect. The tea leaf materials could supply as a reference for high EGCG tea production technology. |
