Evaluation of the validity of temporal sensory evaluation methods carried out by consumers on controlled stimuli delivered by a gustometer

Abstract

Temporal sensory evaluation is increasingly used with consumers. However, very few studies have investigated the repeatability and resolution of the methods used. Thus, this study aimed to fill in the gap by comparing the conclusions drawn from data collected using three temporal sensory methods performed with consumers on time model solutions delivered using a gustometer. One hundred and fifty consumers were recruited. After familiarization and a recognition task, they were divided into 3 panels, each using a different method to describe their temporal perception: Temporal Dominance of Sensations (TDS), Temporal Check-All-That-Apply (TCATA), and Attack-Evolution-Finish (AEF). Fourteen solutions of varying complexity were evaluated, including four evaluated twice. These solutions delivered by the gustometer varied in composition (including 3 to 5 sapid or aromatic compounds: acid, salty, sweet, lemon, and basil), in intensity levels (weak, medium, and strong), and in delivering order.The temporal resolution and the repeatability of the 3 sensory evaluation methods decreased with the complexity of the stimuli. While the sensory perception concurred with the composition of the solutions for simple stimuli, some unexpected results were observed when interactions between compounds occurred. Surprisingly, at the panel level, the conclusions were very similar to TDS and TCATA although they were supposed to measure different concepts (dominance vs. applicability). As expected, TDS and TCATA were superior to AEF in their capacity to highlight temporal changes during the tasting, but as a static method, AEF performed better to detect the presence of the compounds in more complex solutions. These results show that taking into account the temporal dimension in sensory perception is very challenging.
