Free sorting task of chocolate proteins bars: Pilot study and comparison between trained and untrained panelists

Abstract

A free sorting task was applied to sort chocolate proteins bars by trained and untrained panelists. Trained and untrained panelists sorted the nine chocolate proteins bars samples into groups. They were then asked to describe in their own words after the sorting was done. Multidimensional Scaling and Correspondence Analysis were performed on these data. Results showed that trained and untrained panels sorted the chocolate proteins bars in a similar way (RV coefficient value). The results also show that the trained panel was significantly more objective than the untrained panel. However, comparable terms were used similarly by both panels and statistical results indicated that untrained and trained panels could be used for free sorting tasks as both panels were able to perform the test being discriminative. Practical ApplicationsThe free sorting task method was used for the first time to differentiate a complex food product with trained and untrained panelists. This task associated with word association was a success and enable the use of this sensory method to potentially understand a strategic local market with consumer feedback.
