If a product developer wants to know whether there is a difference in how tartness of two beverages is liked, which sensory testing would be appropriate?

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

Answer: (A)

When you want to know if people like the tartness of two beverages differently, you’re measuring a consumer liking response. Acceptability testing captures exactly that: how much respondents like each product. You’d have people taste both beverages, rate their liking (often on a hedonic scale), and compare the results to see if there’s a significant difference in preference for the tartness. This directly tells you whether one beverage’s tartness is liked more than the other. Discrimination tests would only reveal if tasters can tell the beverages apart at all, not whether they prefer one level of tartness. Descriptive tests would describe the intensity of sensory attributes (like how tart each sample is) but not how much they’re liked. A difference test likewise focuses on whether a perceptual difference exists, not on liking. So the acceptability test is the appropriate choice for assessing differences in how tartness is liked.
