Introduction to Sensory Techniques
Pages 6

This introduction is in three parts. The first part lists some reasons why sensory tests are

performed and briefly traces the history of their development. The second part introduces

the basic approach of modern sensory analysis, which is to treat the panelists as measuring

instruments. As such, they are highly variable and very prone to bias, but they are the only

instruments that will measure what needs to be measured; therefore, the variability must

be minimizes and the bias must be controlled by making full use of the best existing

techniques in psychology and psychophysics. In the third part, a demonstration is

provided of how these techniques are applied with the aid of seven practical steps.
