Age-related changes in oral and nasal physiology and their significance in aroma release and perception

Abstract

With aging comes many physiological changes, including those in the oral and nasal cavity, such as impaired olfactory function, reduced salivary flow and compromised dental status and function [1-3]. These changes may impact on aroma release and flavour perception, and subsequently the enjoyment of foods, leading a risk of undernutrition. This review aimed to summarise current literature on how olfaction is affected by aging, the major physiological parameter in flavour perception. With the worldwide projected increase in the older population, the economic and social burden of undernutrition is expected to be severe. Tackling this issue is of interest to both clinical practice and industry, as there is potential for new products to be developed which meet the needs and sensory preferences of this specific, increasing population.
