How can you create a sensory panel that accurately represents your target population?

3 Determine your sample size

Another factor to consider when creating your sensory panel is the sample size, which refers to the number of panelists you need to obtain reliable and representative results. The sample size depends on several factors, such as the type of sensory test, the variability of the product and the panelists, the level of precision and confidence you require, and the budget and time constraints you have. Generally, a trained panel requires a smaller sample size (around 10-15) than an untrained panel (around 50-100), because trained panelists are more consistent and sensitive in their evaluations. However, you should always consult statistical methods and tools to calculate the optimal sample size for your specific case.

4 Recruit your panelists

Once you have decided on your panel type and sample size, you can start recruiting your panelists. You can use various methods and sources to find potential panelists, such as online platforms, databases, social media, referrals, or advertisements. However, you should always screen and select your panelists based on your criteria and objectives. For example, if you are testing a product for children, you should recruit children of the appropriate age group and their parents or guardians. If you are testing a product for a specific market segment, you should recruit panelists who match the demographic and psychographic profile of that segment. You should also exclude panelists who have allergies, intolerances, or aversions to the product or its ingredients, or who have medical or ethical reasons to avoid it.

5 Train or instruct your panelists

Depending on your panel type, you may need to train or instruct your panelists before conducting the sensory test. For a trained panel, you need to provide intensive and repeated training sessions to teach them how to identify, measure, and rate the sensory attributes of the product using standardized methods and scales. You also need to calibrate them regularly to ensure their consistency and accuracy. For an untrained panel, you need to provide clear and simple instructions to explain the purpose, procedure, and expectations of the sensory test. You also need to ensure their comfort and motivation by providing a suitable environment, equipment, and incentives.

6 Monitor and evaluate your panel

The final step in creating your sensory panel is to monitor and evaluate its performance and feedback. You need to check the quality and validity of the sensory data collected from your panelists, and identify and correct any errors, biases, or outliers. You also need to assess the satisfaction and engagement of your panelists, and solicit their suggestions and comments. By doing so, you can improve your sensory panel and test design, and ensure that you obtain reliable and representative results that reflect your target population.
