黄大茶感官特征定量描述与风味轮构建

Sensory Characteristics of Yellow Large Leaf Tea by Quantitative Descriptive Analysis and Construction of Flavor Wheel

依据GB/T 16861—1997《感官分析通过多元分析方法鉴定和选择用于建立感官剖面的描述词》和定量描述分析研究黄大茶的感官风味特征。由评价小组自由产生描述词,初步得到110个描述词,通过删除快感术语、定量术语、近义术语等,并结合M值法和相关性分析对描述词进行删减、合并,最终整理得到27个描述词汇,以嗅觉和味觉为一级术语,香气、风味、基本味道、口感为二级术语,27个具体描述词为三级术语,绘制出黄大茶的风味轮,并对18个典型风味属性描述词设置了定量参比样,最终建立含有不同强度参比样的黄大茶感官描述词汇表,从而实现了黄大茶定性和定量的感官评审。
