    Exploring the association of personal factors with affective responses to plant-based meat alternatives with consideration of their perceived similarity to meat
    (Elsevier Ltd, 2025-12-01) Giezenaar C; Mehta A; Orr RE; Godfrey AJR; Foster M; Hort J
    Plant-based meat alternatives (PBMAs) have gained popularity as perceived sustainable replacements for meat, yet consumption remains limited. Understanding how personality traits shape PBMA consumption experience is therefore essential. This study surveyed 140 New Zealand consumers, assessing behavioural traits and attitudes related to willingness to reduce meat consumption/increase PBMA consumption. Participants completed tasting sessions evaluating commercially available PBMA products, based on flavour, texture, overall liking and emotions evoked, and sample perceived similarity to meat. Participants reported their demographic information, dietary habits, and frequency of meat and PBMA consumption. Results showed that higher social status derived from PBMA consumption were linked with higher liking ratings and citation proportion of ‘hungry’ for PBMAs. However, high negative attitude towards vegetarianism/veganism was linked to higher citation proportion for ‘unhappy’ for wholefood samples, while lower citation proportion for ‘unhappy’ for somewhat meat-like samples. High meat attachment was associated with lower perceived similarity to meat in both meat-like and somewhat meat-like samples. Additionally, the high meat consumption group reported lower texture and overall liking for meat-like samples. High variety seeking consumers (VARSEEK scores) were positively associated with flavour and overall liking for wholefood samples. Based on dietary groups, meat avoiders, generally driven by environmental and animal welfare concerns, reported more negative emotions such as ‘unhappy’ when tasting wholefood PBMAs compared to omnivores and flexitarians, despite their strong ethical and environmental motivations. The research highlights the impact of consumer behavioural traits and attitudes on their PBMA perception and acceptance, providing valuable insights for improving product development.

    Consumer responses to smoke-impacted pinot noir wine and the influence of label concepts on perception
    (Elsevier Ltd, 2025-02-01) Fryer JA; Dupas de Matos A; Hort J; Tomasino E
    While wildfire's impacts on wine have been considered a defect due to the introduction of smoke-related off-flavours, limited studies have investigated consumers responses to smoke-impacted wines. The aims of this work were (i) to explore how New Zealand consumers respond to smoke-impacted wine; (ii) confirm whether clusters of consumers existed and characterise them by their liking of smoky flavours in foods/beverages and subjective wine knowledge; and (iii) explore how different label concepts influence consumer responses. Participants responded to liking, emotions, and perceived sensory attributes of five blends of smoke-impacted wine with non-impacted wine, along with a smoke-impacted wine presented with four different label concepts. Two clusters of consumers were identified, with one disliking the smoke-impacted wine (smoke-dislikers) and the other cluster liking (smoke-liker). The smoke-liker cluster indicated a greater liking of smoke flavours in foods and beverages, along with a higher level of subjective wine knowledge. For the labels, the introduction of the label concept significantly increased liking of the wine for the smoke-dislikers, as well as had the power to elicit different emotions and sensory experiences. This research provides vital information to the wine industry as they adapt to future wildfire years, along with how the distinct sensory profile may not be detrimental to consumer acceptance and can be modulated by the type of information on label. Further research is needed to explore how different populations and wine styles correlate with these findings, and the effects of varying levels of smoke exposure in Pinot noir and other grape varietals.

    Cross-cultural differences and acculturation in affective response and sensory perception: a case study across Chinese immigrants and local consumers in New Zealand
    (Elsevier Ltd, 2025-01) Dupas de Matos A; Chen A; Maggs R; Godfrey AJR; Weerawarna N R P M; Hort J
    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.
