Final answer:
A paired comparison test is used in sensory testing to determine which sample matches a reference sample.
Step-by-step explanation:
The described sensory test is a paired comparison test, a method employed in sensory evaluation. During this evaluation, panelists are provided with a reference sample alongside two distinct samples. Their task is to discern and select the sample that best corresponds to the reference. This test is particularly valuable for determining the likeness or similarity of samples to a standard, contributing valuable insights into product quality, consistency, and sensory attributes. Paired comparison tests are widely utilized in industries such as food, cosmetics, and manufacturing, offering a systematic approach to evaluating and ensuring product uniformity and meeting consumer expectations.
