Sensory Discrimination Testing: Linking Internal Panelists and Consumers

Taught by Dr. Benoît Rousseau

Abstract:

 

Discrimination testing is one of the favorite investigative tools at CPG companies when studying the suitability of an ingredient change or the relevance of a product improvement. The tetrad, triangle, or 2-Alternative Forced Choice (2-AFC) methods involve simple experimental designs and have the potential of delivering valuable decisional information in a cost-effective and timely manner.


One potential weakness of a company’s internal discrimination testing program is that it might not accurately predict the consumer’s experience so that its results could lead to incorrect decisions: The market release of a product change that consumers will reject, or the non-release of a cost-reducing option that consumers would have accepted.

 

To increase the accuracy and relevance of an internal panel’s recommendations, the sensitivity link between consumers and internal panelists should be studied. In this webinar, we will describe how this can be done from a theoretical and practical point-of-view. We will review the key ideas behind Thurstonian modelling, a theory that provides a unique framework to link different method and panel performances, as well as describe academic and industrial applications of these ideas. We will conclude by illustrating how these insights will result in optimized study specifications from a methodological and internal sample size perspectives.

This webinar is intended for a general audience of sensory professionals and graduate students. No detailed technical knowledge is assumed.
