The same samples were used for both the projective mapping and ultra-flash profiling panels, and the trained descriptive analysis panels. Within these panels, two experiments (non-barium and barium) were conducted with nine samples of thickened liquid, ranging from thin to extremely thick, in each experiment. All samples were prepared at the University of Guelph, Canada. In the first experiment, a commercial thickening agent from Nestle Resource®: either Thicken Up® (TU; modified cornstarch) or Thicken Up Clear® (TUC; xanthan gum), was added to a base of Lemon Splash Water (Nestle Pure Life) according to the recipes shown in Table 1. In the second experiment, the same thickening agents were added to water (Nestle Pure Life) with 20% w/w added barium sulfate (E-Z-Paque®, 96%), in amounts shown in Table 1. The sample formulations were determined through preliminary trials and were confirmed to fall within the levels of the IDDSI framework and remain within those levels for a period of at least 3 hours post mixing.
Samples for both experiments were made using the same protocol. Samples were made by whisking the weighed thickener and/or barium sulfate into 22°C moving water with a stand mixer (Bosch Compact MUM4405) for 2 minutes, and then left to rest for 1 hour prior to serving. Samples were always kept at room temperature (22°C).
