Item 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 JPlant-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.Item Perception and acceptance of high seaweed content novel foods (Ulva spp. and Undaria pinnatifida) across New Zealand and Singaporean consumers(Elsevier BV, amsterdam, 2024-12) Chen A; Lim AJ; Lin JWX; Oh G; Teo PS; Bowie D; Deb-Choudhury S; Samuelsson LM; Chan JCY; Ng SB; Foster M; Giezenaar C; Hort JEdible seaweeds are gaining global popularity as nutritious and sustainable food sources, extending beyond Asian into Western diets. To investigate consumer perception and acceptance of high seaweed content foods, two novel products, seaweed dumplings and pasta, were developed using the mixture of Ulva spp. and Undaria pinnatifida as a primary ingredient. Consumer evaluations were conducted in New Zealand (NZ, n = 157) and Singapore (SG, n = 176). Results showed low overall liking and willingness to purchase for both products in each country, though NZ consumers rated them more positively in terms of liking, healthiness and sustainability than SG consumers. Willingness to purchase was positively correlated with ratings of liking, healthiness, and sustainability. Emotional responses differed by country and product, with more NZ participants reporting positive emotions (e.g., pleased, happy, hopeful and loving) and dumplings evoking more activate emotions (e.g., energetic, shocked and amazed). Umami taste enhanced overall liking in both countries, while slimy texture (NZ) and fish-like flavour (SG) decreased overall liking. These results underscore the current challenges in consumer acceptance of high seaweed content novel foods, but also highlight cross-cultural differences that can guide the development of seaweed-based foods in global markets.Item 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 JPlant-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.
