摘要
This review summarises the investigations and findings made on the factors affecting the quality of black tea in Sri Lanka. The chemical composition of tea flush and their contribution during manufacture including polyphenols, theaflavin, thearubigin, polyphenoloxidase and pectin towards quality have been reviewed. Tea quality in relation to fermentation period, flavour compounds and clones, Mn content, chlorophyll content, climatic condition and shade, manuring and storage are the other aspects covered.
