Sensory claims provide a compelling way of differentiating products in a crowded market.  However, before making any claim about the taste of a food or beverage, it is essential to have up to date and relevant evidence to support that claim. Discrimination tests are often essential for this purpose but often not well understood.

In our experience many discrimination tests (evaluating differences or similarities between samples) are designed around practical constraints (cost/availability) rather than on sound statistical principles. This workshop looks at methods for defining similarity/difference thresholds, as well as test methods and analyses for robust sensory claims testing.

This is a practical session where you will get:

  • Presentation of the main discrimination tests of interest
  • Quantifying test risks
  • Importance of looking at confidence intervals as well as significance tests
  • Are Difference/Similarity Tests the same?
  • Comparison of different methods (e.g. Triangle v Tetrad)
  • How to quantify a difference – proportion of distinguishers v d-prime? What are the advantages of each?
  • Replicating to increase sample size – is it OK?
  • Making sensory claims – does your data support your claim? Is your data robust enough?
  • Hands on experience in setting up and running discrimination tests using EyeQuestion and EyeOpenR
  • A tour of the logic8 facilities
