Shelf-life Project and Management

Shelf-life Project and Management

Design a Shelf-life project

For a Shelf-life test, you can evaluate products at different moments. To do that you can include different sessions in your design which will correspond to different time points when the products will be tested.

Step 1. Generate a design with multiple sessions by clicking on Design (1)>Generate Design (2)>Repeat Design (3). In the example below, a design that will be repeated six times is created. This means that each product will be evaluated six times. 


Step 2. You can add a description of your Products (1) as well to your Sessions (2) and you can indicate the start and end date of each session. A session represents a timepoint, e.g. Day 1, Week 2, Week 4 etc.




Run the questionnaire:

Through a computer/tablet in a sensory booth:

  1. Click Allocate to open the allocate screen.
  2. Select the location/room you want to allocate the project to.
  3. Allocate your project to all booths in this room, or to one booth. Select your project in the drop-down list behind ALL.
  4. Select the session at which you want the project to start, for the first evaluation this is S1, for the next evaluation this is S2 etc.
  5. Click save to your changes.


Through email:

  1. In the project that you want to send click Distribution and add the panelists that you would like to be included in the tes. 
  2. Click then Contact Panelist for sending out the link of the questionnaire.  
  3. You can send an Invite, a Reminder to panelists that were invited but did not finish yet, or decide to send an Email to all your panel. 
  4. You can decide to send the questionnaire for all the sessions or just for a specific one. 



Shelf-life Data Analysis

Once the data are all collected, it is possible to analyse them through EyeOpenR. 
Step 1. Open EyeOpenR by clicking on Tools>Analysis Tools>EyeOpenR or directly from your project by clicking on Data>EyeOpenR logo.
 
Step 2. Select the method that you would like to use for the analysis. 


Step 3. In the Options setting, it is possible to analyse the Sessions separately. Each combination of a product and a session will then be considered as a separate product.

Product Database

Please note: this option is available within the professional license.

The Product Database (PDB) can help building Shelf-life tests as it keeps track of all the product information that can be used, and makes sure this information is consistent in your projects. The PDB can be created by clicking on Tools>Data Tools>Product Database.

Before products can be imported to be used in an EyeQuestion project, an excel file with product data has to be created. The image below shows an example of how an excel file can be created to be used with the PDB.

When you then add a product in your project, you can select it directly from the PDB. 


Shelf Life Management

Please note: this option is available within the corporate license and can be added as an extension to the professional license.

This option allows making schedules for your own product sample. It automatically connects with the Product Database (PDB).  
Step 1. When creating a Shelf-life Sample you need first to search for the products that you want to test according to a Shelf-life time schedule. 
Step 2. Once the product is selected, you can add information regarding the product production and a Batch and Sample Identifier. In the Time Points section is possible to add the information regarding the time interval that the product will be tested. 




Step 3. When it will be time to make the evaluation of the sample, EyeQuestion will notify you when is the moment to evaluate the sample in Design>Products.


Step 4. Once the product is evaluated, this information will be also stored in the Shelf-life Management. 

Step 5. Is it also possible to Generate a Report by clicking on
