The objective of the study was to establish differences in the taste intensity and hedonic responses of young and elderly subjects to five standardised commercial-like apple juice samples with varying amount of added sucrose (0-10% w/w). The results were intended to be of potential use as predictive tool for consumption level of fruit juices by ageing population. Thirty-five elderly (60-88 years) and thirty-three young adults (20-30 years) participated in the study, the last serving as a control group. Sweetness, sourness and degree of liking was evaluated. In the elderly the mean results showed flatter response of perceived intensity in both tastes as compared with young subjects. Elderly men seemed to be less sensitive than elderly women to changes in sucrose concentration and less positive in their most liked sample. In opposite, there was no difference due to sex in young adults neither in intensity slopes, nor in hedonic optimum distribution. Individual intensity and hedonic data (on the example of elderly and young male subjects) demonstrated high subject-to-subject variability, especially in elderly individuals. Within the young subjects the responses showed some regular and repeatable intensity/hedonic relations.
