中文摘要: 对不同树龄来源的英红九号红茶的茶多酚、氨基酸、可溶性糖、茶黄素等主要品质成分含量进行测定,并对干茶品质进行感官审评。结果表明:除可溶性糖含量新树红茶稍高于老树红茶外,其他品质成分,如茶多酚、氨基酸、咖啡碱、黄酮类、水浸出物、儿茶素总量和茶黄素总量都是老树红茶显著高于新树红茶。审评结果表明,老树红茶在茶叶外形、香气、汤色、滋味等方面均优于新树红茶,与品质成分的趋势一致。

Abstract:The main components of tea polyphenols,amino acids,soluble sugar,theaflavins etc.in Yinghong NO.9 black tea from tea trees of different ages were measured,and sensory tests of dry tea quality was carried out.The results showed that soluble sugar content of black tea from the new tree was slightly higher than that from the old tree.But other quality components,such as tea polyphenols,caffeine,amino acids,flavonoids,water extract,total catechins and theaflavins,their contents of black tea from the old tree were significantly higher than those of the new tree.The results of the sensory tests of dry tea quality showed that the tea shape,aroma,tea infusion,taste of black tea from the old tree was superior to that of the new tree.
