研究收集了浙江省特别荣誉名茶西湖龙井和浙江省十大名茶2013年不同等级的78个样品,进行感官审评与理化分析。感官审评发现,浙江省“十大名茶”随着等级下降,茶叶风味品质逐渐降低,级差明显。对不同样品的理化成分按照等级进行一般判别分析,趋势较好。文章对浙江省“十大名茶”的香气、滋味类型,香气和滋味中的缺陷类型与数量进行了归纳与统计。在此基础上,总结出浙江省“十大名茶”品质特征,对各个名茶的香气、滋味类型进行了解析与重构,首次绘制完成了浙江省“十大名茶”香气、滋味风味轮。
78 samples of different grades（including top famous tea and special famous tea in Zhejiang province）were collected in this research. Through the sensory evaluation, an obvious flavor changes between different grades were found. While processing the data of chemical compounds in different grade samples with discriminant analysis, a well judgment can be shown, which is essentially in agreement with the sensory evaluation result. The quantity of samples with different aroma and taste types was counted, and then the characteristics of each tea were summarized. Flavor wheels were drawn after the analysis and reconstitution of the flavor types.
