Abstract

Novel and reformulated food, in particular protein-enhanced drinks, provide an important strategy to promote healthy eating. Despite their availability, protein-enriched foods are not widely accepted, likely owing to their unexpected “taste”. Those expectations change with experience and exposure may improve product acceptance. However, the sensory drivers of this phenomenon are unknown. In this randomised, controlled, multi-center trial with pre and post intervention measurements, 100 healthy adult participants consumed either a novel protein-enriched milk drink (PD) or a conventional milk drink (CD) for seven days. Participants evaluated familiarity and hedonic value of the taste, smell, and flavor of different milk drinks including the intervention drinks in the laboratory before and after a seven day exposure. A novel protein-enhanced drink was evaluated after intervention only. Exposure to PD increased familiarity of its smell, taste, and especially flavor. The perception of the other non-exposed drinks was unchanged. PD exposure also led to increased taste familiarity of a novel protein drink suggesting that the “acquired taste” transfers to other protein drinks. While PD hedonic ratings were unaffected by exposure, increased familiarity was positively associated with hedonic ratings for all three sensory modalities smell, taste, and flavor. No changes in the perception of any drink were observed in the group consuming the CD. The transfer of the acquired taste familiarity to a novel drink after 7-days of exposure to an unfamiliar protein-enriched drink indicates that exposure may increase acceptance of similar drinks.
