Sensory testing in new product development: Working with older people

Résumé

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 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 elderlypeople should be required and the precautions to take during a sensory test with elderly subjects.
