The triangle test can indicate whether two products are different or not or more often to ensure that both products are identical. These tests are usually performed when a manufacturer need to change a production process, or switch providers for an important ingredient, but these changes should not affect the finished product, so a triangle test will be asked to know if these changes have altered these products.
A specific protocol will be prepared by the system so that the tasters are not influenced in one way or another, then the system will help to capture and then give statistical results concerning the identity or difference between the products tested.
The implementation of these tests in Tastel is extremely simple, the first phase involves the setting up of the experimental design:
Next to identification and design of the questionnaire are requested, it is also possible to add images on the questionnaire.
Without further manipulation, this initialization allows the display of the questionnaire in the box's input, but also the availability of forms that allow Word© forms deported data entry via Mail attachments.
Immediate results can be displayed as an extent of the data entry. These results can indicate whether the products are significantly different (with the risk alpha) or not, in the second case, the beta risk indicates the risk taken when considering the products to be identical. The given information can also control the number of judges needed in these tests.
In this example, the results can see that both products are different, and therefore to incorporate the ingredient of supplier of X influences the final product (B product in the experimental design) with notes typed less floral and more bitter. Therefore, even if this ingredient may be cheaper, it will be not adviced to buy the ingredient of this supplier due to differences generated on the considered finished product.
It is also possible to ask follow-up on triangle tests to identify a period long enough differences that arise between a standard product and an aging product, for example.
