Consumer perception and emotional responses to plant-based cheeses

Abstract

Consumer interest in plant-based cheeses (PBCs) has increased in the last few years due to consumer concern for animal welfare, environmental impact, and health. In order to increase the acceptability of PBCs, sensory studies must be conducted. As such, the aim of this study was to evaluate the acceptability, sensory properties, and emotional responses to PBCs currently being sold in Canada. There were two different sensory trials conducted. In the first trial (n = 100), raw PBCs were evaluated, and in the second trial (n = 93) melted PBCs were evaluated. In both trials, five different PBCs were evaluated using nine-point hedonic scales, a check-all-that-apply (CATA) question, and the CATA variant of the EsSense25 profile. Participants were also asked to answer open-ended comment questions about PBCs. The results showed that participants thought PBCs are healthier than regular dairy cheese, but they did not like the flavour or textural properties of PBCs. PBCs that are buttery, smooth, and have soft attributes were preferred by the participants. Participants mainly disliked PBCs that were mouthcoating, rubbery, and had off-flavours. The PBCs with higher overall liking scores were associated with positive emotions.
