As a part of the battle against climate change, many plant-based meat alternative products have been launched in recent years—without notable success. One explanation could be that consumers of meat alternatives are seen as socially deviant from those consuming animal-based protein products. This study adopts the BIAS Map framework, which has been underutilized in the food consumption research, in order to reveal the stereotypical beliefs, emotional responses, and behavioral tendencies that consumers of meat alternatives evoke in observers. An online experiment is conducted, participants (N = 3600) from four European countries evaluate fictitious consumers using three shopping lists that include meat products and their alternatives in varying combinations. The results reveal a conflicting picture of those who are believed to favor meat alternatives. They are seen as environmentally friendly, health-conscious people who adhere to high moral standards, and are worthy of admiration. But on the contrary, they also elicit fear, contempt, and anger in observers, who as a result socially exclude and even show aggression toward them. Second, the findings produce a novel insight regarding moderation effects related to observers' need for affiliation and status. Those high in need of affiliation demonstrate the strongest positive change in their relation to consumers who appear to favor both traditional meat products and their more modern alternatives. Additionally, those high in need of status tend to evaluate consumers favoring the modern alternatives as evoking more anger and envy, compared with consumers favoring traditional meat products. This study has several theoretical, managerial, and societal implications.
作为应对气候变化斗争的一部分,近年来推出了许多以植物为基础的肉类替代产品,但都没有取得明显的成功。其中一个原因可能是,肉类替代品的消费者被视为有别于动物性蛋白质产品消费者的社会异类。本研究采用了在食品消费研究中使用不足的 "偏见地图"(BIAS Map)框架,以揭示肉类替代品消费者唤起观察者的刻板印象、情绪反应和行为倾向。我们进行了一项在线实验,来自四个欧洲国家的参与者(N = 3600)使用三份购物清单对虚构的消费者进行评估,其中包括肉类产品及其不同组合的替代品。结果显示,那些被认为偏爱肉类替代品的人的形象是相互矛盾的。他们被认为是环保主义者、有健康意识的人,坚持高道德标准,值得钦佩。但恰恰相反,他们也会引起观察者的恐惧、蔑视和愤怒,从而在社会上排斥他们,甚至对他们表现出攻击性。其次,研究结果提出了一个新见解,即与观察者对从属关系和地位的需求有关的调节效应。那些对归属感需求较高的人在与消费者的关系中表现出最强烈的积极变化,他们似乎既喜欢传统的肉类产品,也喜欢更现代的替代品。此外,与青睐传统肉类产品的消费者相比,地位需求高的观察者倾向于认为青睐现代替代品的消费者会引起他们更多的愤怒和嫉妒。本研究具有若干理论、管理和社会意义。

This study aims to investigate the motivations, enablers, barriers and attitudes towards the vegan movement within people with distinct formal backgrounds in nutrition. To that end, a cross-sectional, qualitative study was conducted with two groups of vegan individuals: registered dietitians or undergraduate nutrition students (NUT) and non-health professionals (NHP). Participants filled out The General Knowledge on Nutrition Questionnaire and attended to focus groups, analyzed using MAXQDA software. Twenty individuals (NUT:7F,3M; NHP:9F,1M), with mean age of 32 ± 12 years, and 24 ± 4 kg/m2 BMI were assessed. NUT presented a higher score of nutritional knowledge. Both groups were motivated by animal welfare and environmental concerns, although NUT group was also influenced by personal relationships, while NHP group highlighted seeking health benefits. Being enrolled in a graduate nutrition program was viewed as a tool to have access to resources, people and knowledge that supported their dietary decisions. NUT group demonstrated greater concern about food quality, choosing unprocessed foods, whilst NHP group demonstrated ethical concerns, preferring to consume from small producers and local businesses. Participant's perceptions were also influenced by their experiences and knowledge, with NHP believing that vegan diets are inherently healthier, while NUT attributed the improved food quality to vegans' careful attention to their dietary choices. Our findings suggest that while both groups share common motivations, their different depths of nutritional knowledge seem to have important impacts on their experience in adhering to a vegan diet, highlighting the critical role of seeking knowledge on nutrition in supporting sustainable vegan dietary practices.
本研究旨在调查具有不同正规营养学背景的人对素食运动的动机、推动因素、障碍和态度。为此,我们对注册营养师或营养学本科生(NUT)和非卫生专业人员(NHP)两组素食者进行了横断面定性研究。参与者填写了《营养常识问卷》,并参加了焦点小组,使用 MAXQDA 软件进行分析。接受评估的 20 人(NUT:7F,3M;NHP:9F,1M),平均年龄为 32 ± 12 岁,体重指数为 24 ± 4 kg/m2。NUT 的营养知识得分更高。两组人的动机都是出于对动物福利和环境的关注,但 NUT 组还受到人际关系的影响,而 NHP 组则强调寻求健康益处。就读研究生营养学课程被视为一种工具,可以获得资源、人员和知识,从而支持他们的饮食决策。NUT 组更关注食品质量,选择未经加工的食品,而 NHP 组则更关注道德问题,倾向于从小生产者和当地企业购买食品。参与者的看法也受到他们的经验和知识的影响,非素食者认为素食本身更健康,而非素食者则将食品质量的提高归功于素食者对饮食选择的细心关注。我们的研究结果表明,虽然这两个群体有着共同的动机,但他们对营养知识的不同了解程度似乎对他们坚持素食的经历有着重要影响,这凸显了寻求营养知识在支持可持续素食实践中的关键作用。

Data from online product reviews offers a novel avenue for the sensory characterisation of food. But, little research has investigated the quality of sensory information in the online reviews. The aim of this research was to investigate consumer online reviews as sources of sensory attributes of food products (starting with a minimum of 1000 online reviews per product), and to assess how the resulting sensory product profiles compare to profiles obtained in a central location test with 105 consumers using rate-all-that-apply (RATA) questions. A case study was conducted with five unflavoured coffee samples. A semi-automated approach, combining natural language processing and sensory science expertise was used to clean online review data, develop a sensory lexicon, and analyse the frequency of attributes used by consumers. It was possible to develop online review-based sensory product profiles and discriminate the five samples on this basis. Consumers used a small set of broad, mostly intensity related sensory terms (e.g. ‘Bold/rich’, ‘Strong/intense’, ‘Smooth’, ‘Weak/bland’) more frequently than descriptive terms. Canonical analysis showed high agreement between new method and RATA for product discrimination and between two group of descriptors. The first group (including ‘Coffee Flavor,’ ‘Rich in Flavor’, and ‘Smell of Coffee’) is associated with the intensity of flavour of coffee, while the second group describes characteristic flavour of coffee (including ‘Bold’, ‘Dark’ ‘Body’). Furthermore, care should be taken when implementing these findings in food categories with lower levels of consumer engagement, where consumer comments relating to sensory properties in online reviews may be less frequent.
来自在线产品评论的数据为食品的感官特征描述提供了一条新途径。但是,很少有研究对在线评论中感官信息的质量进行调查。本研究的目的是调查消费者在线评论作为食品感官属性来源的情况(每种产品至少有 1000 条在线评论),并评估由此得出的产品感官特征与在中心位置测试中使用 "全部适用"(rate-all-that-apply,RATA)问题对 105 名消费者进行测试后得出的产品感官特征的比较情况。对五种无味咖啡样品进行了案例研究。采用半自动化方法,结合自然语言处理和感官科学专业知识,清理在线评论数据,开发感官词典,并分析消费者使用属性的频率。在此基础上,可以建立基于在线评论的产品感官档案,并对五个样本进行区分。与描述性术语相比,消费者更频繁地使用一小套广泛的感官术语(如 "大胆/丰富"、"强烈/浓郁"、"柔滑"、"微弱/平淡"),这些术语大多与强度有关。卡农分析表明,新方法与 RATA 在产品鉴别以及两组描述词之间具有很高的一致性。第一组描述词(包括 "咖啡风味"、"风味浓郁 "和 "咖啡香味")与咖啡风味的强度有关,而第二组描述词(包括 "浓郁"、"深沉 "和 "醇厚")则描述了咖啡的特征风味。此外,在消费者参与度较低的食品类别中应用这些研究结果时应小心谨慎,因为在这些类别中,消费者在在线评论中对感官特性的评论可能较少。

In multisensory environments, odours often accompany visual stimuli, directing attention towards congruent objects. While previous research shows that people fixate longer on objects that match a recently smelled odour, it remains unclear whether odours directly influence product choices. Since odours persist in real-world settings, we investigated the effects of repeated odour exposure on visual attention and product choice, accounting for potential olfactory habituation. In a within-participant design, 30 participants completed a task where either a lemon odour (experimental condition) or clean air (control) was paired with congruent lemon-based food images, which varied to prevent visual habituation. We measured eye movements and choice preferences for these food products.
Results revealed that participants exhibited longer gaze durations and more frequent fixations on food products congruent with the lemon odour. Repeated odour exposure had no effect on gaze patterns, as participants consistently focused on odour-congruent products throughout the experiment. The intensity and pleasantness of the lemon odour remained stable over time, suggesting no olfactory habituation occurred with this food-related odour. Despite this stable visual attention and odour intensity and pleasantness, participants began to diversify their product choices, selecting fewer odour-congruent items over time.
These findings suggest that while odours continue to direct attention towards matching products, repeated exposure may reduce their influence on product choice, highlighting the complex role of olfactory stimuli in decision-making. The study provides insights into how odours interact with visual cues and influence consumer behaviour in prolonged exposure scenarios.
在多感官环境中,气味往往伴随着视觉刺激,将人们的注意力引向一致的物体。虽然先前的研究表明,人们会对与最近闻到的气味相匹配的物体停留更长时间,但气味是否会直接影响产品选择仍不清楚。由于气味会在现实世界中持续存在,我们研究了重复接触气味对视觉注意力和产品选择的影响,并考虑了潜在的嗅觉习惯。在一个参与者内部设计中,30 名参与者完成了一项任务,在该任务中,柠檬气味(实验条件)或清洁空气(对照组)与以柠檬为基础的同义食物图像配对,为防止视觉习惯化,这些图像会发生变化。我们测量了参与者的眼动和对这些食品的选择偏好。结果显示,参与者对与柠檬气味一致的食品表现出更长的注视时间和更频繁的凝视。重复接触气味对注视模式没有影响,因为参与者在整个实验过程中始终专注于气味一致的产品。随着时间的推移,柠檬气味的强度和愉悦度保持稳定,这表明参与者对这种与食物有关的气味没有产生嗅觉习惯。这些研究结果表明,虽然气味会继续引导人们关注匹配的产品,但反复接触可能会降低气味对产品选择的影响,这突出了嗅觉刺激在决策中的复杂作用。这项研究深入揭示了气味如何与视觉线索相互作用,并在长时间接触的情况下影响消费者的行为。

In recent years, there has been significant interest in studying hedonistic food experiences using neurophysiological methods within the field of neuroscience. Understanding the neural mechanisms behind the perception of pleasure and aversion to food stimuli has implications for both the fundamental processes of human sensory and emotional taste processing and for addressing health-related issues such as obesity and eating disorders.
In our study, we used functional near-infrared spectroscopy (fNIRS), heart rate (HR), electrodermal activity (EDA), and electromyography (EMG) to measure brain and peripheral nervous system reactions to pleasant and neutral foods.
Using fNIRS, we found that while the insula was activated in response to subjectively pleasant food, the right precentral gyrus was activated in response to neutral taste. This finding suggests interhemispheric asymmetry in relation to neutral taste. The EMG results demonstrated that the corrugator facial muscle was sensitive to neutral food, whereas the zygomaticus facial muscle was sensitive to pleasant food. EDA responses were larger for pleasant food, and HR increased in response to all food stimuli.
The convergence of neuroimaging and peripheral physiological results provides a powerful framework for advancing our understanding of hedonistic responses to food. By elucidating the neural and physiological bases of food hedonics, researchers can gain insights into the complex nature of human appetite.
近年来,人们对利用神经科学领域的神经生理学方法研究享乐主义食物体验产生了浓厚的兴趣。了解对食物刺激的愉悦感和厌恶感背后的神经机制,对人类感官和情绪味觉处理的基本过程以及解决肥胖和饮食失调等健康相关问题都有意义。在我们的研究中,我们使用功能性近红外光谱(fNIRS)、心率(HR)、皮肤电活动(EDA)和肌电图(EMG)来测量大脑和外周神经系统对愉悦和中性食物的反应。这一发现表明,大脑半球之间在中性味觉方面存在不对称性。肌电图结果表明,皱纹肌对中性食物敏感,而颧面肌对愉悦食物敏感。神经影像学和外周生理学结果的融合为我们进一步了解对食物的享乐主义反应提供了一个强有力的框架。通过阐明食物享乐主义的神经和生理基础,研究人员可以深入了解人类食欲的复杂本质。

The paradox of choice: How indulgent options enhance subsequent healthy decision-making in consumers with low dietary self-control 选择的悖论:放纵的选择如何促进低饮食自控能力消费者的后续健康决策

Through four studies, we establish that when consumers with low dietary self-control are presented with both healthy and indulgent food options, rather than being limited to only healthy or indulgent choices, their likelihood of selecting a healthy option in a subsequent choice significantly increases. We contend that the presence of an indulgent option along with a healthy option enhances the relative appeal of health-related goals by prompting tradeoff analyses between competing goals of health and indulgence. We found that this effect is particularly pronounced among consumers who exhibit limited self-control over dietary consumption. Our research not only contributes theoretically to the field of consumer successive decision-making but also offers practical implications for individuals and organizations seeking to design effective interventions for individuals highly susceptible to unhealthy dietary choices.
通过四项研究,我们证实,当低饮食自制力的消费者同时看到健康和放纵的食物选项,而不是仅限于健康或放纵的选择时,他们在随后的选择中选择健康选项的可能性会显著增加。我们认为,放纵选项与健康选项同时存在,会促使人们在健康与放纵这两个相互竞争的目标之间进行权衡分析,从而增强健康相关目标的相对吸引力。我们发现,这种效应在对饮食消费自我控制能力有限的消费者中尤为明显。我们的研究不仅在理论上对消费者连续决策领域有所贡献,而且还为个人和组织设计有效的干预措施提供了实际意义,这些干预措施针对的是极易做出不健康饮食选择的个人。

Our research not only contributes theoretically to the field of consumer successive decision-making but also offers practical implications for individuals and organizations seeking to design effective interventions for individuals highly susceptible to unhealthy dietary choices.</div></div>","PeriodicalId":322,"journal":{"name":"Food Quality and Preference","volume":"124 ","pages":"Article 105371"},"PeriodicalIF":4.9,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142701209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growing interest in organic food is driven by consumer concerns about the impact of conventional agricultural practices on human health, and environment. It is crucial to understand the factors that influence consumer preference of organic food. Consumer preferences for organic food has been largely investigated using traditional methods which have limitations in terms of data validity, reliability, time, and cost. This study used social media data to investigate main factors influencing consumer perceptions and preferences of organic food using X’s API. The data were analysed by text mining, and topic modelling.
The results reveal that organic production, sustainability, origin, shelf-life, and price are the five most important factors that influence consumers’ choices for organic food. Organic milk was used as the representative organic food product with attributes and levels established from the social media data analysis. A conjoint analysis was used with a sample of Vietnamese consumers. Sustainability is the most important attribute affecting organic consumer food choices followed by organic production, price, shelf-life, and origin. Segmentation analysis identified two clusters of consumers: in cluster 1 sustainability is the most importance attribute while in cluster 2 organic production is the most importance one.
In conclusion, this study underscored the potential of social media data as a valuable source for understanding consumer behaviour and preferences in the context of organic food consumption. In addition, this study emphasized the significance of sustainability as a critical attribute in consumer decision-making with lower environmental impact influencing consumers’ likelihood to purchase organic food products.
消费者之所以对有机食品越来越感兴趣,是因为他们担心传统农业生产方式会对人类健康和环境造成影响。了解影响消费者对有机食品偏好的因素至关重要。对消费者有机食品偏好的调查大多采用传统方法,这些方法在数据有效性、可靠性、时间和成本方面存在局限性。本研究使用社交媒体数据,利用 X's API 调查影响消费者对有机食品看法和偏好的主要因素。结果显示,有机生产、可持续性、原产地、保质期和价格是影响消费者选择有机食品的五个最重要因素。有机牛奶作为有机食品的代表产品,其属性和等级是通过社交媒体数据分析确定的。对越南消费者样本进行了联合分析。可持续性是影响消费者选择有机食品的最重要属性,其次是有机生产、价格、保质期和产地。分类分析确定了两个消费者群组:在群组 1 中,可持续性是最重要的属性,而在群组 2 中,有机生产是最重要的属性。此外,本研究还强调了可持续性作为消费者决策中的一个关键属性的重要性,即较低的环境影响会影响消费者购买有机食品的可能性。

Edible insects are sustainable sources of animal protein. Although insects are novel foods in Western societies, the Asia-Pacific region preserves traditional entomophagy cultures. In parts of the Asia-Pacific region, the amount consumed gradually declined with each passing generation. Reviving the entomophagy tradition among the younger generation is crucial for the future market for edible insects. This study examined young consumers’ perceptions of edible insects and the psychological determinants of their consumption. This study was conducted in Japan, which is a typical example of generational differences in insect consumption due to traditional eating habits. We adopted the theory of planned behavior (TPB) to identify psychological determinants of entomophagy and conducted two online surveys among 391 and 342 young Japanese consumers, respectively. We extended the original TPB by adopting a treatment–control design in which respondents in the treatment group received information on product availability. The results revealed that edible insects remained a novel food among respondents. The TPB revealed that subjective norms and perceived behavioral control (PBC) were determinants of consumption intention, whereas intention and PBC were determinants of behavior. Information on product availability had a significant positive impact on intention; however, it had little impact on behavior. Furthermore, we found that food safety control was the most valued product attribute and hedonistic attributes were prioritized over functionalist attributes. Based on these findings, this study proposes possible promotional strategies that provide valuable insights for marketers and policymakers in Japan and other countries to revive the entomophagy tradition among younger generations.
食用昆虫是可持续的动物蛋白质来源。虽然昆虫在西方社会是新奇的食物,但亚太地区却保留着传统的昆虫食文化。在亚太地区的部分地区,昆虫的食用量随着时代的变迁而逐渐减少。在年轻一代中恢复昆虫嗜食传统对未来的食用昆虫市场至关重要。本研究考察了年轻消费者对食用昆虫的看法及其消费的心理决定因素。本研究在日本进行,由于传统饮食习惯,日本是昆虫消费存在代际差异的典型例子。我们采用计划行为理论(TPB)来确定昆虫消费的心理决定因素,并分别对 391 名和 342 名日本年轻消费者进行了两次在线调查。我们对原有的 TPB 理论进行了扩展,采用了处理-对照设计,其中处理组的受访者获得了有关产品供应的信息。结果显示,食用昆虫在受访者中仍然是一种新奇的食物。主观规范和感知行为控制(PBC)是消费意向的决定因素,而消费意向和感知行为控制则是行为的决定因素。产品供应信息对消费意向有显著的积极影响,但对消费行为的影响很小。此外,我们还发现,食品安全控制是最受重视的产品属性,享乐主义属性优先于功能主义属性。基于这些发现,本研究提出了可能的推广策略,为日本和其他国家的营销人员和政策制定者提供了宝贵的见解,以恢复年轻一代的昆虫食性传统。

This research evaluates the potential of using visual textural complexity as a subtle yet effective strategy to direct consumer preferences towards more sustainable food choices, addressing the urgent need to reduce greenhouse gas emissions in the food industry.
Using a traditional Turkish rice pudding, sütlaç, as a case study, we prepared four variants with varying textural complexities (ranging from simple to complex) by reducing the portion size by half and gradually adding soft, crispy, crunchy, and airy textured food layers onto it. Two parallel sets of variants were formulated to minimize potential bias from differences in composition and visual properties of the layers. One hundred participants individually evaluated paired visual stimuli of these variants under two experimental conditions: non-informative, which included only visuals, and informative, which included visuals with accompanied by sample information.
Paired binary analysis revealed consistent preference for variants with higher levels of visual textural complexity, especially those with three layers (soft, crispy and crunchy), regardless of experimental conditions and product formulations. Although sample information affected preference scores, variants with certain levels of textural complexity were still preferred over the traditional sample (p < 0.05). Preferences for sample variants over the control reduced the carbon emission over 31 %. The study links the impact of visual textural complexity on preferences to the Elaboration Likelihood Model (ELM) and demonstrates that this strategy can effectively direct consumer preferences towards more sustainable options. Adopting the insights from this study can assist food producers and marketers in contributing to the broader goal of reducing carbon emissions.
本研究评估了将视觉纹理复杂性作为一种微妙而有效的策略来引导消费者偏好更可持续食品选择的潜力,以满足减少食品行业温室气体排放的迫切需要。我们以土耳其传统米布丁(sütlaç)为案例,通过将分量减半并逐渐添加柔软、酥脆、松脆和空气质地的食物层,制作了四种不同纹理复杂性(从简单到复杂)的变体。为了最大限度地减少因各层食物的成分和视觉特性不同而可能造成的偏差,我们设计了两组平行的变体。100 名参与者在两种实验条件下分别对这些变体的配对视觉刺激进行了评估:无信息(仅包括视觉效果)和有信息(包括视觉效果并附有样本信息)。配对二元分析表明,无论实验条件和产品配方如何,参与者都一致偏好视觉纹理复杂度较高的变体,尤其是有三层(软、脆和嘎嘣脆)的变体。尽管样本信息会影响偏好得分,但与传统样本相比,具有一定纹理复杂度的变体仍然更受偏好(p <0.05)。与对照组相比,对样本变体的偏好减少了 31% 以上的碳排放量。该研究将视觉纹理复杂性对偏好的影响与阐释可能性模型(ELM)联系起来,证明这一策略可以有效地引导消费者偏好更可持续的选择。采用本研究的见解可以帮助食品生产商和营销人员为实现减少碳排放这一更广泛的目标做出贡献。
