Visual merchandising of pastries in foodscapes: The influence of plate colours on consumers’ flavour expectations and perceptions

The aim of our research is to find out how pastries should be visually merchandised in retail environments most effectively. In particular, we want to answer the question whether the colour of the surface (black vs. white) against which pastries are presented influences consumers’ expectations (sensory and hedonic), i.e., before tasting (stage 1) and perceptions (sensory and hedonic), i.e., after tasting (stage 2). In addition, we seek to detect any differences in sensory and hedonic evaluations as well as purchase intentions between stage 1 and stage 2.For this purpose, we conducted two studies on a special type of pastries, i.e., macarons: first, based on our observational research, we selected the most popular macaron flavours (colours): pistachio (green), raspberry (pink), coffee (light brown), chocolate (dark brown), lemon (yellow), and vanilla (off-white); second, we carried out a between-participants experiment among 432 participants.Our results reveal that customers seem to show a high degree of identification of the actual flavour in stage 1, with some doubts related to the colours light brown, yellow, and dark brown. Moreover, the assessment of the sensory attributes of crunchiness, creaminess, and sweetness, as well as the hedonic value and purchase intent appear to be higher in stage 2 than in stage 1. Furthermore, no main effects of the plate colour on the evaluations of greasiness, crunchiness, creaminess, and sweetness, as well as the hedonic value and purchase intent in stage 1 and stage 2 could be found. However, while the expectation of greasiness for the macaron colours green, pink, light brown, lemon, and off-white is higher when served on a black plate, for the colour dark brown, the expectation of greasiness is higher when served on a white plate. Finally, managerial implications for retailers, like, bakeries, pastry shops, restaurants, or caterers, are provided, the limitations of our research are mentioned, and avenues for further research are given.
