Sensory Panel

Definition of sensory panel:

Sensory panels are a way to examine all aspects of products. The sensory panel s provide an evaluation of products in terms of appearance, taste, mouthfeel, and taste.

A sensory panel in market research refers to a group of individuals who are trained to evaluate and provide feedback on the sensory attributes of products, such as taste, smell, texture, and appearance. These panels are used to gather objective data on consumer preferences and perceptions. of various products, which can be valuable for product development, quality control, and marketing strategies. The panelists are typically selected based on their ability to detect. and articulate sensory differences., and are often required to undergo rigorous training to ensure consistency. and reliability in their evaluations. The insights provided by sensory panel can help companies. make informed decisions about product formulation, packaging, and positioning in the marketplace. 

Types of panelists:

Sensory panels are classified into three categories, trained, semi-trained, and consumer panels.
Trained panel: A trained panel consists of a small number of members. (5-10 people) who must be carefully selected and trained.
Semi-trained panel: This panel usually consists of about 25 to 30 members. who are somewhat familiar with product quality and classification.
Consumer Panel: Consumer or untrained panel members should be representative of the age., gender, race, and income groups of potential consumers., who are randomly selected. Normally more than 80 members are required to form a consumer panel

Types of sensory panel tests:

Different sensory tests are used in different situations.

Difference or discriminative sensory panel tests: 

The difference test is designed to detect the difference between two or more samples. Types of difference tests:

Paired Comparison sensory panel Test

It is a test of two products (for example, A and B) and the task of the panel is to compare them. and determine whether the samples are similar or not. Paired Comparison tests are usually used to compare new and old processing techniques., change ingredients in a product, test consumer preferences, and more.

Duo-trio sensory panel Test

This test is a modified paired comparison test. In this test, a sample identified as a reference is first provided to the panel members for evaluation. And two coded samples, one of which is similar to the reference, are presented. And the participant is asked to determine which of these two samples is the same as the reference sample.

Triangle Test:

 It is a three-product test. In this test, all samples are coded and the task of the panel. is to determine which two are more similar or which one is more different from the other two.

Multiple Sample Test

A test that includes more than 3 stimuli is classified as a multiple sample test.


In this method, a certain score is given to each sensory feature. The scoring method is the most widely used among all sensory methods. due to its diversity, simplicity, and ease of statistical analysis.


In the ranking method, two or more samples are provided to the participants. and they are asked to sort them according to the intensity. of a specific feature in ascending or descending order.

Hedonic Rating: 

In the hedonic method, the psychological states of liking and disliking are measured on a rating scale.

Descriptive Analysis: 

It involves providing quantitative descriptions of a product., taking into account all the senses that are perceived: such as the sense of sight, hearing, smell, taste, movement, etc.

Acceptance/Preference Testing

This test refers to measuring interest or preference for a product. Preference can be measured directly by comparing. two or more products with each other.
