Consumers’ acceptance of recycled water in meat products: The influence of tasting,attitudes and values on hedonic and emotional reactions

Community opposition to potable recycled water may extend to recycled water in food production. Past research on recycled potable water indicates that the closer the risk of personal contact or ingestion, the less acceptable it is. Despite purification and expert assurances, emotional responses, including disgust, may present as major psychological barriers to the environmental and commercial benefit of recycled water use in food production. Consumers (n = 101) were presented with meat products purported to be processed or containing recycled water (3 levels of proximity to ingestion) along with a control product (containing tap water). Hedonic and 18 emotional responses were elicited. Validated survey instruments were used to measure world views (values), beliefs supportive of environmental actions and food technology neophobia seeking to explain variation in hedonic and emotional responses. Surprisingly, consumers were found to be generally accepting and willing to try foods containing or in close proximity to recycled water when that water was collected, treated and returned to drinking water standards within the factory. All hypotheses pertaining to associated values, beliefs and neophobia were rejected. The study suggests that recycling water within a food factory, when supported by a credible and trustworthy source of information, is likely to be met with positive emotional and affective responses. Using a broad range of affective and emotional responses was useful in understanding acceptance of foods that may be associated with perceived risk.     

Exploring consumers’ perceptions of plant-based eggs using concept mapping and semantic network analysis

Plant-based eggs offer a healthy, animal-free, and more environmentally sustainable alternative to conventional eggs. Given the novelty of these products, it is vital to understand consumers’ perceptions before their market launch. Perception is based on product associations stored in consumers’ memory as semantic networks. In this study we used the graphic procedure concept mapping to elicit associations of 180 consumers from the UK and Italy to explore perceptions of three types of plant-based eggs, namely liquid, powder, and egg-shaped. Concept mapping also allowed to investigate the relevance that these associations have for the consumers. Results show more complex associations among participants in the UK than Italy for all three types of plant-based eggs. ‘Price’ is the most frequently mentioned association by consumers in both countries. In terms of relevance, participants evaluated ‘healthy’, ‘animal welfare’ and ‘sustainability’ as the most important and positive attributes of plant-based eggs. Furthermore, the semantic network analysis showed that the health benefits of plant-based eggs is quickly activated in consumers’ mind and should therefore be emphasized when marketing these products. ‘Use’ of plant-based eggs, e.g., baking, is also a key association, particularly in the UK for the egg-shaped version. However, ‘use’ was generally lower rated, suggesting that the limited applications of this product (only hard-boiled) may be perceived negatively. These findings provide insights into the psychology of consumers’ acceptance of plant-based eggs and have important implications for designing successful marketing strategies for promoting plant-based eggs.     

The whole beast: Consumers’ perceptions of and willingness-to-eat animal by-products

Satisfying the global demand for proteins and avoiding food waste are global challenges. Promoting the consumption of animal by-products might contribute to the solution. The goal of our study was to investigate the role that different factors play for consumers’ willingness to engage with animal by-products. For this, an online survey and experiment with consumers was conducted (N = 260). While food disgust sensitivity works as a barrier, social norms and culinary-based drivers increase people’s willingness to engage with animal by-products. To expand consumer interest, measures could focus on increasing familiarity and reducing negative expectations regarding the sensory qualities of the product.     

Consumers’ associations with herbal infusions and home preparation practices

The consumption of infusions is affected by many factors, namely those associated with culture, health and sensory properties. The main goal of this research was to explore and understand consumers’ perceptions and behaviours regarding consumption and preparation of herbal infusions, applying a mixed methodology: the evaluation of consumers’ behaviours, assessed through direct self-reported measures, and indirect methods, such as free word association and auto-videography. A total of 489 Portuguese consumers replied to a web-based questionnaire. Based on their frequency of consumption and availability, 60 participants were selected for an observational study. Over 27% of the participants had at least a daily cup of herbal infusion, and over 74% had it at least every week. At home, participants reported the use of teapots (44.1%) or mugs/cups (52.0%) to prepare their infusions, and mostly chose bags (77.7%). Approximately 80% of the respondents removed the bags or loose leaves after steeping, mainly based on the infusion colour (53.1%). The freeword association results show that daily and weekly consumers establish a stronger connection with the sensory, emotional, health and wellbeing dimensions of the product, while less frequent consumers only consider the composition of the herbal infusion. From the observational study, it was noticeable that most of the consumers take less than one minute to steep the infusions, clearly below the four to ten minutes recommended for the most popular herbal infusions, like lemon verbena or peppermint. These results emphasize the need for communication strategies focused on the preparation process to give consumers tools to improve their sensory experience.     

Drivers of choice for fluid milk versus plant-based alternatives: What are consumer perceptions of fluid milk?

Fluid milk consumption has declined for decades while consumption of nondairy alternatives has increased. A better understanding of why consumers purchase fluid milk or nondairy alternatives is needed to assist increased sales of milk or maintain sales without further decline. The objective of this study was to determine the extrinsic attributes that drive purchase within each product category. The second objective was to determine the personal values behind the purchase of each beverage type to give further understanding why particular attributes are important. An online conjoint survey was launched with 702 dairy consumers, 172 nondairy consumers, and 125 consumers of both beverages. Individual means-end chain interviews were conducted with fluid milk consumers (n = 75), plant-based alternative consumers (n = 68), and consumers of both beverages (n = 78). Fat content was the most important attribute for dairy milk followed by package size and label claims. Consumers of fluid milk preferred 1 or 2% fat content, gallon, or half-gallon packaging, conventionally pasteurized store-brand milk. Sugar level was the most important attribute for plant-based beverages, followed by plant source and package size. Almond milk was the most desirable plant source, and half-gallon packaging was the most preferred packaging. Means-end chain interviews results suggested that maintaining a balanced diet and healthy lifestyle was important to all consumer groups. Lactose free was an important attribute for plant-based alternative consumers and consumers of both dairy and nondairy. A distinguishing characteristic of those who only drank nondairy plant-based alternatives was that plant-based beverages contributed to a goal to consume less animal products, beliefs about animal mistreatment, and perceived lesser effect on the environment than fluid milk. Unique to fluid milk consumers was that fluid milk was perceived as a staple food item. These results suggest that the dairy industry should focus on the nutrition value of milk and educating consumers about misconceptions regarding dairy milk. Future beverage innovation should include the development of lactose-free milk that is also appealing to consumers in flavor.     

Beyond information seeking: Consumers’ online deliberation about the risks and benefits of red meat

Successfully engaging consumers in a dialogue may provide opportunities for better tailored and more effective communication about food-related risks and benefits. Using an online deliberation concept and software, VIZZATA™, we explored the validity of a behavioral measure of deliberation in an online environment in the context of consumers’ perceptions and information seeking about the risks and benefits of red meat. Participants from Belgium, Portugal and the United Kingdom (n = 150) were given the opportunity to engage in an asynchronous interaction with the research team about the information provided. Online deliberation was operationalized as an individual metric based on the number of questions asked in relation to the information, the number of comments left, the number of glossary terms accessed, and the time spent on deliberative activity. This operationalization provided a coherent measure of deliberation which was positively correlated with information recall about the risks and benefits of red meat. Participants who perceived the information about red meat risks and benefits as too complex engaged less with the information. The study herewith presents a novel method of investigating consumers’ deliberation about food issues that conceptualizes consumer engagement as more than just information seeking.     

The consumer’s perception of artificial food additives: Influences on acceptance,risk and benefit perceptions

Food additives, such as food colours or sweeteners, play an important part in food supply. For a variety of reasons, some consumers might regard the use of food additives, especially artificial ones, with suspicion; food additives are considered unnatural, unhealthy or even a public health risk. The goal of this study was to investigate consumers’ perceptions and the most essential variables related to the acceptance of food additives. Two versions of a paper-and-pencil questionnaire, one investigating artificial food colours and the other investigating artificial sweeteners, were distributed to a large sample of Swiss German households. The final samples for artificial food colours and artificial sweeteners comprised 506 and 487 participants respectively. The questionnaires contained items on consumers’ acceptance, risk and benefit perception, trust in regulators, knowledge of regulation and their preference for natural products. The relationships between variables were investigated in a path model, which was constructed based on a review of previous literature. The path coefficients suggested that risk and benefit perceptions significantly influence the acceptance of the two selected food additives. The risk and benefit perceptions were influenced by consumers’ knowledge of regulation, their trust in regulators, and their preference for natural products. In the discussion, the study’s findings are examined in terms of their implications for further research and for the development of concrete communication materials.     

Consumers’ attitudes towards and acceptance of 3D printed foods in comparison with conventional food products

Little research currently exists in the literature on consumers’ perceptions of 3D printed foods; thus, present research aimed to investigate this topic. Two focus groups (n = 8 and 12) were conducted to identify what consumers believe about 3D food printing. Responses from the focus groups were used to create an online survey investigating consumer attitudes towards 3D printed foods in comparison with conventional foods, as well as consumer beliefs about 3D food printing. Based on the results of the survey, three clusters were identified: the markedly interested cluster (n = 140), moderately interested cluster (n = 98) and the not interested cluster (n = 91). The markedly interested cluster wanted to know more about 3D printed food, and believed it could reduce the cost of food and benefit people in the future. The moderately interested cluster was excited to try printed food. Conversely, the third cluster believed 3D printed foods were unacceptable and not safe to consume.     

Consumers’ perceptions of organic food attributes and cognitive and affective attitudes as determinants of their purchase intentions toward organic food

The current study investigates how consumers perceive organic food attributes, which in turn influence their utilitarian and hedonic attitudes and intentions to purchase organic food. Specifically, consumers’ perceptions of nutritional content, ecological welfare, and price attributes of organic food have strong effects on utilitarian attitudes as well as hedonic attitudes toward buying organic food, while perceptions of the sensory appeal attribute have a strong effect on hedonic attitudes. Interestingly, consumers’ perceptions of the natural content attribute of organic food are not a significant determinant of the two dimensions of attitude. Lastly, utilitarian and hedonic attitudes play an important and influential role in determining behavioral intentions to purchase organic food. This study raises questions about the lack of a theoretical framework in previous organic food studies. Therefore, a modified S–O–R model is applied to provide theoretical support for organic food research. In addition, this study employs a bi-dimensional approach to attitudes (i.e., utilitarian and hedonic attitudes), contributing to a better understanding of consumers’ expectations and perceptions in their behaviors regarding organic food.     

A review of the structure,function, and application of plant-based protein–phenolic conjugates and complexes

Interactions between plant-based proteins (PP) and phenolic compounds (PC) occur naturally in many food products. Recently, special attention has been paid to the fabrication of PP–PC conjugates or complexes in model systems with a focus on their effects on their structure, functionality, and health benefits. Conjugates are held together by covalent bonds, whereas complexes are held together by noncovalent ones. This review highlights the nature of protein–phenolic interactions involving PP. The interactions of these PC with the PP in model systems are discussed, as well as their impact on the structural, functional, and health-promoting properties of PP. The PP in conjugates and complexes tend to be more unfolded than in their native state, which often improves their functional attributes. PP–PC conjugates and complexes often exhibit improved in vitro digestibility, antioxidant activity, and potential allergy-reducing activities. Consequently, they may be used as antioxidant emulsifiers, edible film additives, nanoparticles, and hydrogels in the food industry. However, studies focusing on the application of PP–PC conjugates and complexes in real foods are still scarce. Further research is therefore required to determine the structure–function relationships of PP–PC conjugates and complexes that may influence their application as functional ingredients in the food industry.     

Consumers’ associations with wellbeing in a food-related context: A cross-cultural study

Consumers’ perception of wellbeing in a food context can affect food choices and might provide a more holistic evaluation of products than overall liking or healthfulness scores. However, considering that wellbeing is a broad concept which lacks of a unique definition, it is necessary to explore how consumers perceive wellbeing in a food-related context. The present work aims at exploring consumers’ associations with wellbeing in a food-related context, taking into account the views of consumers from five countries: Brazil, France, Portugal, Spain and Uruguay. A total of 755 consumers were asked to complete a questionnaire comprising five open-ended questions about foods and wellbeing. The elicited terms were translated into English, coded and grouped into categories. The frequency of mention of the categories was determined and differences among countries were evaluated. In the five countries wellbeing was mainly associated with calmness, health, happiness, food products, positive emotions and satisfaction with specific aspects of life. The effects of foods on wellbeing were strongly related to physical health, pleasure and emotional aspects. Meanwhile, consumers regarded sensory characteristics, manufacturing processes, nutritional composition and context of food consumption as the main factors underlying food-related wellbeing. Vegetables, fruits, fish and seafood, meat products, grains and cereals, and dairy products were the main foods recognized as positive for wellbeing, whereas foods high in fat, salt and sugar, meat products, junk food and fried food were perceived as harmful. Significant differences among countries were identified in the frequency of mention of the categories elicited in the five questions, suggesting that culture affected consumers’ associations with wellbeing.     

To meat or not to meat? Comparing empowered meat consumers’ and anti-consumers’ preferences for sustainability labels

An increasing awareness of the impact of high levels of meat consumption on health and environmental sustainability is leading to a growing number of consumers reducing or avoiding meat. To address gaps in the literature, we compare and contrast the importance of the seven sustainability-related labels for three consumer groups (meat eaters, meat reducers and vegetarians) using a choice experiment involving 600 UK respondents (200 meat eaters, 200 meat reducers, 200 vegetarians). Type of meat, price and fat content labels have the largest overall impact on consumer choices. The impact of carbon footprint, method of production, origin and brand labels varies across consumer groups.We subsequently use latent class analysis to identify heterogeneous intra-group consumer segments, based on their preferences, and highlight the socio-demographic differences between them. For meat eaters, three consumer segments are identified (empowered, traditional and price conscious meat eaters). Meat reducers are divided into health curtailers and sustainable consumers, while only one segment of vegetarians is identified. By drawing on signalling theory and the consumer empowerment and anti-consumption literature, we identify links between sustainable consumption, consumer empowerment and anti-consumption and provide valuable insights for policymakers and practitioners seeking to utilise food labels to encourage more sustainable consumption.     

Americans’ acceptance of black soldier fly larvae as food for themselves,their dogs,and farmed animals

This paper investigates consumer attitudes towards Hermetia illucens larvae (aka Black Soldier Fly Larvae; BSFL) and other insects in two forms: dried whole insects and insect flour incorporated into a familiar food. In two studies, we assessed the willingness of American adults to try eating them directly, eating animals fed on them, and feeding them to their pet dog. Participants were significantly more willing to try food made with insect flour than to eat the whole insects, with the same pattern emerging for acceptability of insects in dog food. BSFL were roughly as acceptable as other insects (crickets, mealworms, ants). On average, participants had negative attitudes towards eating BSFL on their own, but the majority were willing to try foods containing BSFL in the form of insect flour or rendered fat. There are also suggestions in the data that indirect routes of consumption (e.g., consuming animals that have eaten insects, or feeding insects to one’s dog) are more acceptable than direct consumption. Our results suggest that BSFL are relatively well-received by consumers and are a promising alternative to the farmed animals more commonly used in pet food.     

Consumers’ attitude towards food by-products: the influence of food technology neophobia,education and information

The aim of the present study was to investigate how food technology neophobia level, socio-economic variables and information about novel foods and technologies may affect consumers’ attitude towards uses of food by-products in relation to positive effects on environment and consumers’ health. Results suggested that education and, most of all food technology neophobia and information, can be critical factors in facilitating the widespread adoption of new food technologies. Moreover, positive attitudes towards food by-products were found, even in people characterised by a greater food neophobia and lower education level. These positive attitudes could be considered a starting point for the food industry to design novel recycling strategies of food by-products in the perspective of the circular economy.     

Extruded meat alternatives made from Maillard-reacted beef bone hydrolysate and plant proteins: part I – Effect of moisture content

This study investigated the effects of moisture content (MC) on the physicochemical properties of extruded meat alternatives made from Maillard-reacted beef bone hydrolysate and plant proteins. Samples were extruded at 170 °C (maximum barrel temperature), at 3.6 kg h⁻¹ (liquid feed rate) and at 1.8, 2.2, 2.6 and 3.0 kg h⁻¹ (dry feed rates) to obtain MC of 60%MC, 56%MC, 52%MC and 49%MC, respectively. Meat alternatives at 52%MC showed the greatest degree of texturisation. However, meat alternatives at 49%MC were the closest in terms of both textural and microstructural properties to reference sample, boiled chicken breast. Results from protein solubility suggested that a large amount of aggregated proteins were associated with hydrogen bonds, while disulphide bonds were the main contributor in the formation of fibrous structure in meat alternatives. Results showed that the change in MC as process parameter played an important role in the formation of fibrous structure in extruded meat alternatives.     

A comparative analysis of experts’ and consumers’ perceptions of regionality in Australian wine purchase decisions

This study provides insight into consumers’ perception of regionality when purchasing regional wine in terms of regional specialisation for style, volume of production of the wine style, quality of the wine, heritage of the wine region and the distinctiveness of the wine styles produced in the wine regions of Australia. Data were collected from 203 Australian wine consumers through an online survey. The study compares the results of this study with Easingwood et al. [2011. The drivers of wine regionality. Journal of Wine Research, 22(1), 19–33.] study on experts’ opinion of regionality drivers. This paper will expand knowledge on how consumer involvement levels impact decisions relating to purchasing regional wine. This study is of value to academics and wine practitioners alike. It contributes to the wine literature by providing a new perspective on consumers’ perception and draws attention to the risk of drawing conclusions about wine consumption based on experts’ opinions as being reflective of the average consumers’ purchase decision-making.
