摘要:本文以不同配方的桃味茶饮料为研究对象,开展评价小组和消费者对其产品重要感官属性的感官评价,采用方差分析、蛛网图和主成分分析等统计分析方法,多角度进行风味特征关联性分析,并利用偏好图技术对定量描述分析(quantitative descriptive analysis,QDA)结合消费者喜好数据进行处理。结果显示:4 款桃味茶饮料风味属性各具特点,采用主成分分析结合方差分析和蛛网图更能直观展示出样品风味的区别与联系;通过偏好图分析技术初步发现了驱动消费者喜好的桃味茶饮料属性,从而为该类饮料产品开发提供指导。

Abstract: This article focused on the sensory evaluations of peach- flavored tea beverages with different formulas,which were conducted by both sensory panel and consumers. The statistical analysis including analysis of variance(ANOVA),cobweb map and principal component analysis (PCA) were used to analyse the relationship amongsensory attributes. And the preference mapping was adopted to study the data of QDA and consumer preference. Theresults showed that the 4 kinds of peach-flavored tea beverages have their own sensory characteristics. Moreover,thedifferences and the relationships of the sample’s flavor were shown much more intuitively by using PCA ,ANOVAand cobweb map. And the drivers of consumers’liking of peach-flavored tea beverages were initially found by usingpreference mapping,so as to provide guidance for the development of such beverage products.
