Which sensory test is used to determine whether tasters can perceive a difference between two similar samples?

• A. Triangle test
• B. Descriptive test
• C. Difference test
• D. Acceptability test

Answer: (C)

This question is about whether tasters can tell two similar samples apart. A difference test is built for exactly that purpose: it checks if a perceptible difference exists between products that are designed to be similar. When two samples are presented, the goal is to determine if the testers can perceive any difference between them, rather than describing the flavors or measuring how much people like the product. A paired comparison setup is a common way to implement a difference test: two samples are presented side by side and tasters indicate which one is different (or if they’re the same). This focuses on the ability to perceive a difference, not on characterizing attributes or overall liking. Other options serve different aims. A descriptive test trains tasters to describe sensory attributes like sweetness or aroma, not whether a product differs from another. An acceptability test asks about liking or preference, not whether a perceptible difference exists. A triangle test involves three samples and asks which one is different, which is still a difference test but requires three samples rather than focusing on comparing two. So the test that best fits the goal of determining whether tasters can perceive a difference between two similar samples is the difference test.
