Very few studies today validate the use of various sensory tools among elderly subjects, although the population is ageing rapidly. This chapter deals with applied sensory assessment in the food sector. It first presents heterogeneity factors in this population: physical and psychological health and dependency, decrease of chemosensory capacities, changes in oral-motor skills and modifications of cognitive abilities. Then, a study aiming at comparing the capacity of young and more or less dependent elderly subjects to use a discrete scale (discriminatory power and repeatability) in a monadic sequential presentation is described. Finally, recommendations are given about the cases where a panel of elderly people should be necessary and the precautions to undertake during a sensory test among elderly subjects.
