以岳西翠兰为研究对象,寻找一个合适的冲泡温度,使茶叶中对人体有益的成分浸出量最大。以生物化学方法测定了不同冲泡温度下茶水中的氨基酸和茶多酚的含量,再综合考虑氨基酸、茶多酚和酚氨比来确定一个最适的冲泡温度。实验结果表明岳西翠兰在用100℃沸水冲泡时,茶多酚的浸出量过大而使茶汤呈苦涩味,随冲泡温度降低,当冲泡温度为50℃时,茶多酚的浸出量趋于最佳。氨基酸浸出量则随着冲泡温度的降低而升高,酚氨比随冲泡温度的降低而降低,而酚氨比值越低,茶汤的口味就越好。初步认为岳西翠兰的最适冲泡温度为50℃。
以嶽西翠蘭為研究對象,尋找一箇閤適的遲泡溫度,使茶葉中對人體有益的成分浸齣量最大。以生物化學方法測定瞭不同遲泡溫度下茶水中的氨基痠和茶多酚的含量,再綜閤攷慮氨基痠、茶多酚和酚氨比來確定一箇最適的遲泡溫度。實驗結果錶明嶽西翠蘭在用100℃沸水遲泡時,茶多酚的浸齣量過大而使茶湯呈苦澀味,隨遲泡溫度降低,噹遲泡溫度為50℃時,茶多酚的浸齣量趨于最佳。氨基痠浸齣量則隨著遲泡溫度的降低而升高,酚氨比隨遲泡溫度的降低而降低,而酚氨比值越低,茶湯的口味就越好。初步認為嶽西翠蘭的最適遲泡溫度為50℃。

Yuexi Cuilan is the object of our study, looking for a suitable brewing condition, to make the tea beneficial to hu- man body. By the biological chemical method, we determined the content of amino acids and tea polyphenols at different temperatures. Then we combined amino acids and tea polyphenols to determine an optima/brewing temperature. Experimen- tal results showed that the content of tea polyphenols was excessive resulting in the tea a bitter taste when temperature brew- ing was 100~C boiling water, and with a lower brewing temperature 50~C, the content of polyphenols resulted in a better taste. While the content of amino acid increased along with the brewing temperature decreased. Therefore the ratio of tea polyphenols to amino acids was lower. Generally, the lower ratio means the better taste of tea. According to the experimental results, we can initially think the optimal brewing temperature of Yuexi Cuilan is 50℃.
