摘要: 以英红九号红茶为供试材料,采用国家审评冲泡方法,对5类水样(超纯水、自来水、天然山泉水、天然矿泉水、纯净水)及其冲泡茶汤的色泽、pH、电导率、主要品质成分含量进行检测,并进行了相关性分析,研究不同类型水质对英红九号红茶茶汤色泽及其品质成分的影响。结果表明,水样的pH、电导率及溶解性总固体含量越高,茶汤明亮度越低,红色度越高;不同水质对茶汤中总儿茶素,特别是酯型儿茶素等浸出量的影响显著。

Abstract: Yinghong No.9 black tea was chosen as test material for investigation of the color, pH, electrical conductivity and main quality components of tea infusion when five types water (ultra pure water, tap water, natural mountain spring water, natural mineral water, purified water) were applied. Through correlation analysis, the effects of different water quality on the color and quality components of Yinghong No.9 black tea soup were studied. The results showed that pH, conductivity and soluble solids content of water samples increased, brightness of tea infusion decreased and redness increased, different water quality had significant influence on the total catechins, especially ester catechin.

Key words: water quality, black tea, Yinghong No.9, quality, physicochemical composition
