Although acceptability is commonly used to examine liking for food products, more studies now emphasize the importance of measuring consumers' conceptualizations, such as emotions for food products. It is also important to identify how consumers perceive the sensory attributes of food products, as illustrated by the increasing involvement of consumers in product characterization. The objective of this paper is to examine the use of a wheel-format questionnaire to obtain both an emotional and sensory profiles for food products using a hands-on consumer tool. Terms selected were product-specific and the rate-all-that-apply (RATA) approach was used as a scaling technique. Three different experiments demonstrated that the EmoSensory® Wheel could discriminate within and between food product categories. The added value of the RATA approach was illustrated in the sample discrimination for some food products when using the weighted attribute scores for analysis. The tool was used in both blind and informed conditions to illustrate its applicability across different experimental designs. In general, the respondents did not find the task tedious when using the wheel-questionnaire format, demonstrating the potential for collecting information in a more facile way. Although further studies with other food products are needed, this paper shows the potential for using this wheel format to obtain information about consumers' emotional and sensory profiling of food products.
尽管可接受性通常用于检验对食品的喜好程度，但现在越来越多的研究强调测量消费者概念化的重要性，比如对食品的情感。识别消费者如何感知食品的感官属性也很重要，消费者对产品特性的参与度不断提高就说明了这一点。本文的目的是使用一种便于操作的消费者工具，通过轮式问卷来获取食品的情感和感官特征。所选术语是特定于产品的，并且使用适用即打分（RATA）方法作为一种量表技术。三项不同的实验表明，情感感官轮能够区分食品类别内部和之间的差异。在使用加权属性得分进行分析时，RATA方法的附加值在一些食品的样本区分中得到了体现。该工具在盲测和知情条件下都得到了使用，以说明其在不同实验设计中的适用性。总体而言，受访者在使用轮式问卷形式时并未觉得任务乏味，这表明以更简便的方式收集信息具有潜力。尽管还需要对其他食品进行进一步研究，但本文展示了使用这种轮式形式获取有关消费者对食品情感和感官特征信息的潜力。
