duo-trio test

A duo-trio test is a sensory evaluation method used to determine if a consumer can distinguish between two different products. In this test, participants are given a reference sample and then asked to identify which of two other samples matches the reference. It’s commonly used in food, beverage, and product development to assess differences or detect changes between products. The test is straightforward: participants choose the sample they believe is the same as the reference, helping producers understand if differences are noticeable to consumers.
