Temporal drivers of liking for oral nutritional supplements for older adults throughout the day with monitoring of hunger and thirst status

Participants seemed to be able to perform these rather sophisticated tasks quite well. Their use of the hunger scale was quite narrow and ONS consumed at the lab reduced hunger very moderately, at least compared to a regular meal being taken at home. Both products increased thirst by an average of 2 scale points along the ten sips, confirming that drinking an ONS increased thirst during tasting. Interestingly, no difference in liking was observed in the first sip, but one of the two products was slightly more appreciated on average over multiple sips. Temporal drivers of liking of this preferred product may be due to longer lasting praline and coffee-milk flavours and shorter metallic flavor and dry sensations.
