Differences in citation proportions in CATA questions can be interpreted as differences perceived intensity of sensory attributes

CATA (check-all-that-apply) questions enjoy high popularity for sensory product characterization with consumers. Amidst extensive methodological characterization, the meaning of term citation frequency has received modest attention only,
possibly hindering further uptake. The present research performed a more detailed exploration of the relationship between CATA responses and perceived intensity of sensory attributes. In addition, the following question was addressed:
How many consumers are necessary to interpret differences in CATA citation proportions as a proxy of differences in perceived intensity? The present research includes new empirical data from four consumer studies conducted in New Zealand and China under central location test conditions and a re-analysis of
one consumer study. When dealing with samples with clear differences, the percentage of consumers selecting a sensory term for describing samples tended to be linearly correlated to average intensity ratings. A median of 15 consumers was
needed for CATA to show good linear correlations with average intensity ratings, and the minimum number of consumers needed to reach the threshold for a good correlation was generally lower than 30.
