Sensory tests can be analytical (based on differences) or affective (based on acceptability or preference): analytical tests. There are two types of analytical tests: difference/discriminative and descriptive. Used to determine if there are differences between two products. Typically a control and a test sample are used. Examples of difference/discriminative tests include triangle test and duo-trio test. Triangle test: participants are given 3 number coded samples and told to choose the sample that is most different. Two of the samples are usually the same (only the researcher knows this). Typically used when the difference between the products is qualitative. Example of a triangle score sheet and table 3. 1: triangle test design. Duo-trio test: one reference sample is presented, followed by two test samples (one of which is the same as the reference).
