    Understanding cross-cultural variation in perception is essential for identifying culture-specific factors impacting product acceptability. While immigrants may initially maintain their preferences, acculturation levels vary. To understand to what extent immigrants can be used as a proxy to model overseas markets, this study investigated short (CHS) and long-term (CHL) Chinese immigrant responses to plain yoghurts compared to New Zealand (NZ) Europeans (E). Three groups (CHS, CHL and NZE, n = 222) evaluated liking of, emotional response to, and sensory perception of 10 plain yoghurts. Groups liked yoghurts similarly. Notably, NZE rated emotions lower than both immigrant groups, with a few exceptions. Both Chinese groups rated most emotions similarly, but CHL rated some closer to NZE. Positive emotions correlated with higher liking scores. However, cross-cultural differences existed for ‘guilty’ which was associated with yoghurts liked by NZE; and for ‘wild’ and ‘mild’ associated with yoghurts disliked by both immigrant groups. Citation proportions for some sensory attributes differed among all groups, dependent on the sample. But level of acculturation between immigrant groups was limited. Sweetness, vanilla, stone fruit and cream flavours, smoothness, and creaminess drove liking across all groups, whereas only the Chinese valued umami, undoubtedly due to positive associations with it. Some effects of acculturation for long-term immigrants were evident, but responses were often closer to their short-term counterparts. Therefore, immigrants in general provide a useful proxy for measuring consumer responses in early stages of product development for this overseas market, but with consideration of their residence time in the host culture.

    Profiling the novel plant-based meat alternative category: Consumer affective and sensory response in the context of perceived similarity to meat
    (Elsevier Ltd, 2024-07) Giezenaar C; Orr R; Godfrey AJR; Maggs R; Meika F; Hort J
    Plant-based meat alternatives (PBMAs) are increasingly popular and may contribute towards reduction of negative environmental impacts associated with the meat industry. Inferior sensory characteristics of PBMAs, compared to conventional meat products, remain a barrier for uptake of these products. This study aimed to profile a wide range of PBMAs for perceived similarity to meat, consumer liking, emotional response and sensory experience, and to determine consumer drivers of liking for this product category. Twenty-one PBMAs, spanning a broad range of product types (burger patties, sausages, meatball alternatives, chicken/beef pieces, bacon alternative, turkey roast alternative) and main protein ingredients (extruded plant proteins, tofu, or legumes/vegetables) representative of PBMAs available to Aotearoa New Zealand consumers, were tasted and evaluated by 140 Aotearoa New Zealand residents. Samples ranged widely in their perceived similarity to meat (median value range: 1.0–4.0 on a 5-point-scale) and overall liking ratings (mean ± SD, range: 35.1 ± 1.2––77.7 ± 17.4 on a 100-point hedonic scale). Overall liking ratings were driven mostly by liking for flavour, followed by texture, and less so by appearance. Sensorially, sample differentiation was mostly associated with variation in meat-related flavours and textures, or vegetable-related attributes. Notably meat flavour was the main driver of liking, and a very strong relationship (r = 0.92) was observed between perceived similarity to meat and overall sample liking ratings. Meat-like samples were also associated with positive emotional terms, whereas samples made from wholefoods were associated with negative emotional terms. Textural terms (‘gluey/slimy’, ‘pasty/doughy’) associated with wholefood products were also negative drivers for liking, and should be avoided in future PBMA products. In conclusion, the general population maintains a strong preference for PBMAs that are similar to meat, validating ongoing efforts to improve the meat-like properties of new and emerging products. PBMAs made from wholefoods require extensive product development to achieve consumer satisfaction across the category.

    Understanding consumer acceptability of verjuice, its potential applications and sensory and chemical drivers of liking
    (Elsevier Ltd, 2024-07) Dupas de Matos A; Reis MG; Maggs R; Hort J
    The wine sector is working to add value, enhance sustainability and reduce waste, yet often creating new products with unknown consumer acceptance. Verjuice, juice made from discarded unripe thinned grapes, is an example. Whilst verjuice has various culinary uses, its versatility in beverages continues to expand. However, its sensory drivers of liking when consumed as a drink, and their potential impact on its application remain unclear. Chemical drivers of sensory characteristics are also unknown representing a critical knowledge gap needed to guide product innovation. This study aimed to provide new knowledge regarding consumer acceptability of verjuice by identifying its sensory drivers of liking as a beverage, evaluating its potential use in different applications and identifying chemical drivers of its sensory characteristics. New Zealand consumers (n = 93) evaluated 13 verjuice samples from different countries. Furthermore, verjuice familiarity and its influence on emotional response was investigated to determine likely future consumer engagement. Sweetness was the most positive driver of liking in verjuice overall, followed by fruity and floral notes, smoothness, and to a lesser extent citrus flavour. Consumers expressed varied preferences for verjuice’s sensory profile, with fruity, floral, and honey flavours driving beverage application, whilst winey and green apple notes were more associated with culinary scenarios. Some association between chemical parameters and sensory attributes were evident (e.g. sugars were highly associated with perceived sweetness, fruity, and floral attributes; these attributes also shared proximity with 1-hexanol and cyclohexanol). The general idea of verjuice elicited positive valence emotions, but consumers who were ‘not familiar’ felt more curious, and those ‘familiar’ felt happier and more satisfied. Findings highlight the potential to tailor verjuice for specific applications by understanding desired sensory profiles and related chemical parameters. Recognising the interplay between familiarity level and emotional response is crucial for positioning the product in the marketplace and fostering consumer engagement. Marketing initiatives are needed to increase verjuice familiarity and support product innovation, leading to increased product appeal.
