Trained panelists are usually preferred for which type of sensory testing?

• A. Discrimination
• B. Affective
• C. Preference
• D. Descriptive

Answer: (D)

Descriptive sensory testing relies on a trained panel because it requires a precise, standardized description of many attributes and their intensities. Panelists learn a shared vocabulary for attributes such as aroma notes, flavors, textures, and aftertastes, and they rate how strong each attribute is in each sample using calibrated scales. This training and calibration ensure measurements are repeatable and comparable across samples and panelists, producing a detailed sensory profile or fingerprint of the product. Affective or preference testing focuses on how much consumers like or dislike a product, which is driven by personal response rather than specific attribute measurements, so it typically uses untrained consumer panels. Discrimination tests are about detecting whether samples differ at all, which can be done with trained or untrained testers but does not yield the attribute-by-attribute profile that descriptive testing provides.
