摘　　要：本实验在传统茶叶感官审评方法的基础上,探讨定量描述分析法(quantitative descriptive analysis,QDA)和适合项勾选法(check-all-that-apply,CATA)评价黄大茶香气感官特性的应用可行性。QDA过程中10名优选评价员自由使用描述词,根据几何平均值M筛选16个描述词,建立具有不同强度参比样的黄大茶感官描述词汇表;CATA法通过问卷设计了18个香气描述词、10个情绪描述词,由招募的100名消费者评价员对问卷词汇进行评判。结果表明,CATA法和QDA法均筛选出相似的感官描述词及香气感官特性:其中QDA法准确率高,能够准确区分香气强度差异;CATA法能够相对轻松、快速且低成本地从消费者中获取香气特征差异。此外,通过引入消费者喜好度检验明确了低焙火和高嫩度的黄大茶更受欢迎。本研究利用QDA法和CATA法明确了黄大茶的香气感官特性及消费者对黄大茶的喜好,可为黄大茶生产企业提供参考,有助于促进黄大茶消费市场繁荣。Based on the traditional tea sensory evaluation method,this study examined the feasibility of the application of quantitative descriptive analysis(QDA)and check-all-that-apply(CATA)in the evaluation of sensory aroma characteristics of large-leaf yellow tea.In the QDA,10 selected panelists generated descriptors freely,and selected 16 descriptors according to the geometric mean value to established a sensory vocabulary for large-leaf yellow tea with reference samples of different intensities.A total of 18 aroma descriptors and 10 emotion descriptors were designed by CATA,and the vocabulary of the questionnaire was evaluated by 100 consumers recruited.The results showed that CATA and QDA could select similar sensory descriptors and aroma characteristics.QDA had higher accuracy and could distinguish the difference in aroma intensity.CATA was a relatively easy,fast and low-cost method for obtaining differences in aroma characteristics from consumers.In addition,consumer preference test results showed that low-roasting and high-tenderness large-leaf yellow tea was more popular with consumers.This study can provide a reference for large-leaf yellow tea manufacturers and help in making the large-leaf yellow tea consumption market flourish.
