Sensory Evaluation Techniques
Sensory evaluation can be divided in two categories of testing: objective and subjective. In objective testing, a selected or trained panel assesses the sensory attributes of a product, where subjective testing measures the consumers' overall preference or acceptance of a product. Tests include:
Descriptive testing
Used to determine whether two or more samples are perceived as different.
Discrimination testing
Identifies and describes the nature of the difference or the magnitude of difference between two or more samples.
Benchmarking testing
Compares test sample to a well-liked product. Benchmarking new products alongside the current market players provides information on how well new product should be accepted once placed on the market. It mainly involves consumer testing carried out with a high number of untrained panelists. In addition to consumer testing, descriptive analysis of the new product versus a well-liked competitor product provides useful information on which product attributes that are key drivers of consumers' acceptance.
Consumer Testing
Can be used to determine whether a product will be accepted by consumers or is preferred compared to another. It provides information on the overall acceptability of a product. It is carried out by a high number of untrained consumers to represent the population.
Sensory projects on Food and Consumer Products
For example, if the objective of the project is to determine how well a product is liked by consumers, then an acceptance test is the correct choice.
