摘要:以白牡丹为研究对象,探究不同茶水比、冲泡时间、冲泡温度对白牡丹冷泡法感官品质和主要成分含量的影响,得出白牡丹冷泡法最佳冲泡组合为冲泡100 min、茶水比1∶50、冲泡水温20 ℃。通过冷泡、热泡对比以及冷泡4 h的感官审评及呈味物质含量对比分析表明,白牡丹冷泡法具有一定的优越性,值得推广。

Abstract: This study used white peony tea as the research material to explore the effects of different tea/water ratio, brewing time and brewing temperature on the sensory evaluation and main component contents of white peony tea by cool-brewing method. The results indicate that the best tea-brewing combination was that brewing for 100 minuteswith the ration of tea to water at 1g :50 mL, and the water temperature was 20 ℃. The comparison of the sensory evaluation and taste compound contents by the cool brewing, hot brewing and the cool-brewing for 4 h show that cool-brewing style of the white peony tea has certain advantages and is worthy of promotion.
Keywords: white tea, cool brewing, sensory evaluation, biochemical components
自明朝推行茶叶泡饮法以来,人们已习惯现泡现饮的饮茶方式[1],但随着现代生活节奏的加快,便捷化的茶叶冷泡方式开始被大众广泛了解和接受。冷泡茶,简单来说就是用冷水(常温或者冷藏的矿泉水、纯净水)来冲泡茶叶。与热泡茶相比,冷泡茶的冲泡方法独特,可以较好保留茶叶中的多酚类成分。有研究表明,茶叶冷泡后多酚类和咖啡碱的溶出率相对于热泡茶减少,而茶氨酸和多糖类的溶出率要比传统热泡茶高,可减少茶汤苦涩味,增加鲜醇感;且降低茶汤中咖啡碱含量,可减缓其对胃的刺激性,因此敏感体质或胃不太好的人都比较适合饮用[2-3]。总体而言,冷泡茶具有方便、健康、可久泡的特点。
白茶,属轻微发酵茶,是我国传统的六大茶类之一,品类包含白毫银针、白牡丹、贡眉、寿眉等。近年来,白茶在国内发展迅速,被认为最具保健功效的茶叶之一[4]。白茶性寒凉,是民间常用的降火良药。自古以来,就有许多关于白茶清凉解毒、治疗养护麻疹患者的记载。……
