摘要/Abstract

摘要： 咖啡冲煮控制图在咖啡行业有着广泛的应用。借鉴咖啡评价指标,以六安瓜片为研究对象,将体现风味平衡度和浓度的萃取率（Extraction yield,EY）及总溶解固体（Total dissolved solids,TDS）用作评价茶汤的质量指标。应用生存分析法确定实现六安瓜片茶汤最大消费者接受度的最佳EY范围为2.53%~4.57%,最佳TDS范围为0.14%~0.28%,并以此为“理想”区域建立了六安瓜片冲泡控制图,在消费者层面和专家层面均得到了验证。研究表明,采用茶水比（g∶mL）为1∶30~1∶15,温度在85~100 ℃时,第一泡茶汤在33 s内调节冲泡时间,第二泡茶汤在15 s内调节冲泡时间,第三泡茶汤在13 s内调节冲泡时间,可以得到“理想”区域的茶汤。本研究为科学地冲泡六安瓜片及其他绿茶提供了理论支持。

Abstract: The Coffee Brewing Control Chart is widely used in the coffee industry. According to the evaluation indices of coffee, this study applied extraction yield (EY) and total dissolved solids (TDS), which represent flavor balance and strength respectively, as quality indices to evaluate Lu'an Guapian green tea (LAGP) infusion. The optimum range of EY and TDS which yielded the maximum consumer acceptance were estimated by survival analysis. EY ranged from 2.53% to 4.57%, and TDS ranged from 0.14% to 0.28%. The LAGP Brewing Control Chart was established regarding the optimum range as the “ideal” zone. The chart was verified by both consumers and experts. This study indicates that when tea to water ratios (g∶mL) ranged from 1∶30 to 1∶15, brewing temperature ranged from 85 ℃ to 100 ℃, regulating brewing time of the first, second and third infusion less than 33 s, 15 s and 13 s, respectively, the ideal infusion can be gained. The study scientifically provided theory basis for guiding green tea brewing like LAGP.

Key words: Lu'an Guapian green tea, quality indices, survival analysis, brewing control chart, brewing parameters
