The triangle test is an example of which type of sensory test?

• A. Descriptive test
• B. Affective test
• C. Difference test
• D. Preference test

Answer: (C)

In sensory evaluation, tests are categorized by what they measure: discrimination (difference), descriptive profiling, affective (acceptability), and preference. The triangle test is a discrimination test. It presents three coded samples—two identical and one different—and asks tasters to pick the odd one out. This setup is all about detecting whether a perceptible difference exists between samples, not about describing the attributes that change or judging how much one sample is liked or preferred. It’s not about describing flavors or textures (that would be descriptive), not about how much someone likes a product (that would be an affective test), and not about which sample is preferred (that would be a preference test). The triangle test specifically assesses whether a difference can be perceived.
