RapiTests for Sensory: - Combines internet with in situ exposure of products - Is Central Location (CL) based - Uses either incentivized street intercept respondents or screened “expert” consumers - Adapts to different sensory evaluation methods - Is conducted in major cities of Europe and worldwide

6. Adapted methods for different needs, requirements (1/2) Consumers + Expert Consumers Panel Position several products on a map according to their similarity (the closer, the more similar). Analysis: Photo decryption, analysis Napping Projective mapping Quantitative Descriptive Analysis or profiling monadically characterises a product by scores, on a linear scale, through several consensual descriptors Analysis: Principal component analysis (PCA) QDA / DA (see example next slide) Profiling to profile, distinguish and map products. A monadic characterisation of a product by scoring, on a linear scale, several descriptors chosen by the consumer. Analysis: Generalised procrustes analysis Free Choice Profiling Creation of groups of similar products, which is quite easy and suitable when testing a larger number of products. It is possible to identify potential consumer sub-groups by the way in which they perceive, and thus better understand the “individual” reactions. Also enables comparisons between professionals, expert consumers and general consumers. Analysis: Multidimensional scaling Free Sorting Consumer / Expert Consumer Objectives

7. An Example: Quantitative Descriptive Analysis Method Test (QDA) Recruitment Training Tie break among alternatives Tasting Grid answering Recruitment Vocabulary generating Test (Preparation when no experts) Although some sensory evaluation methods might be complex and take some time for respondents to complete, RapiTests speed ensure that results are delivered very rapidly once fieldwork is completed

8. Adapted methods for different needs, requirements (2/2) Consumers Expert Consumers Panel JAR measures levels of a product’s attribute relative to a respondent’s theoretical ideal level. These scales have an anchored midpoint of “just about right” or “just right”. Wit Ideal Profile Method, scaling of several products on a set of relevant sensory attributes (both perceived and ideal intensity is asked) and on hedonic aspects. JAR (Just About Right) scaling and Ideal Profile Method Elicitation process to generate vocabulary differentiating a product from the others Repertory grid Quickly assesses, profiles and maps products through potential sensory attribute choices (without scaling) Analysis: cross tabs & factorial analysis CATA (Check All That Apply) Consumer Objectives Obtains a sequence of the dominant sensations occurring in mouth/usage/ during consumption of the product. TDS is found to better enhance the sequence of sensations over time. TDS (Temporal Dominance Sensation) Comparative characterisation of several products by ranking, on a linear scale, several descriptors chosen by each assessor. Flash Profile Expert Consumer Objectives

10. Outputs examples The significancy tests (t-test) compare measures, and are suitable for small samples. To get a t-test for example on the extent of the preference we divided the mean measure by the standard error. When a red letter is placed next to a measure, it means it is significantly higher to the other measure of the indicated column(s). Lower case characters (i.e. “b”) show significant superiority for a 90% I nterval Confidence , upper case at (i.e. as above “B”) 95% IC. Analysis conducted in collaboration with
