Impact of circular economy information on sensory acceptability, purchase intention and perceived value of upcycled foods by young consumers.

The acceptability of upcycled foods is influenced by individual, context and product-related factors. This study aimed at investigating the impact of circular economy (CE) information on consumers' sensory acceptability, purchase intention and perceived value of upcycled foods, taking into account eating behaviours and personality traits that could be related to the consumers' sustainable consumption habits. To this aim, a group of young subjects (n = 80, 18-35 years old) participated in a two-step study. Firstly, an online questionnaire was administered to participants to gather information about their individual characteristics. Then, participants were divided into two groups, one receiving CE information (CE+) and one not receiving it (CE-), and they were asked to indicate the sensory acceptability, purchase intention and the perceived value of three upcycled foods, such as biscuits with grape pomace flour, beer brewed with leftover bread and a dairy product made from recovered crushed cheese. Questionnaire results showed that high individual responsibility, interest in healthy foods and high awareness of the social impact of their behaviours could be linked to a positive purchase intention for upcycled foods, as opposed to individual disgust sensitivity. No significant effect of CE information (p > 0.05) on sensory acceptability and purchase intention of all three upcycled foods was observed. Moreover, application of Principal Component Analysis (PCA) to the sensory data resulted in satisfactory classification of upcycled foods in terms of perceived values, explaining 86.83 % of data variability: the first principal component discriminated samples according to product category whereas the second principal component was able to clearly separate products according to CE information. Findings from this study provided valuable insights into the key individual characteristics that impact sustainable consumption habits, also highlighting the role of communication strategies in shaping consumer perceptions of upcycled foods so as to encourage a more sustainable consumption behaviour.
