Abstract: Research involving measurements of sensory perception within the older adult population is complicated by difficulties with traditional testing methods for these individuals. A trend in food sensory testing is the use of rapid profiling techniques. These methodologies have been found to produce results very similar to those of a trained panel with a much smaller time commitment from panelists and at a much lower cost. Three rapid profiling techniques – Napping®, sorting and check-all-that-apply (CATA) – were tested in older adult populations (aged 60+). Participants (n=60) attended three sessions where seven commercially available instant and ready-made puddings along with two duplicate samples were evaluated using one of the three rapid profiling methods. All three methods appeared to produce valid results in the older testing group, however, higher panellist reliability, lower difficulty and higher percentage of correct completions led to the conclusion that CATA is the most appropriate rapid profiling test for older adults.
