Sensory basis of refreshing perception: role of psychophysiological factors and food experience.
Refreshing is a term often used to characterize certain types of foods and beverages. This review first explores what is known from sensory and consumer studies on refreshing perception in relation to food and beverage consumption. It then presents and discusses the similarities between sensory characteristics perceived as refreshing with those perceived during and after drinking water. In general, refreshing drinks and beverages seem to help alleviate symptoms experienced during water deprivation, including thirst, mouth dryness and mental fatigue. The role that learning may have in the construction of refreshing perception during each food experience is also discussed. The review showed that a refreshing value (perceived or expected) tends to be associated with foods sharing some characteristics with water in terms of their sensory profile (clear, cold, liquid); and that food experiences may induce associative learning about perceptions of existing or new products marketed as refreshing.
