Test methods
Objective tests
Difference tests
Used to determine whether a sensory
difference between the two products
exists .
z.B.: Triangle test, Paired comparison test,Difference-from-control test
Descriptive tests
Used to determine the sensory
characteristics of a product or
determine the nature and intensity ofa difference between products.
z.B.: Flavour profiling, Quantitative Descriptive
Analyse (QDA)
Subjective tests
Affective tests
Used to measure preference and/oracceptance (laboratory, centrallocation or home use tests)
z.B.: Preference test, Acceptance test

Expert panel
2-5 panelists
Experts (e.g. flavourists)
Used for the higher school of
sensory evaluation, flavour
profiling, control purposes and
product development
Trained laboratory panel
5-20 panelists
For certain testing methods
specially trained panel
Used for difference tests, easy
quality control purposes;
mixed with experts for flavour
