RESUMO

The naming and labeling of products can affect consumer attitudes and subsequent behavior, particularly in the case of new food products in the market. The present study explores the effects of name framing on consumer attitudes towards cultured meat (CM), which is currently in the early stages of development. With a sample of 1532 Chinese consumers, we integrated several pathways to explain the name-framing effect by examining three different terms ("cultured," "artificial," and "cell-based") for CM. Results indicate that "cultured meat" and "cell-based meat" are more appealing than "artificial meat." Name framings of CM affect consumers' perception of benefits more than that of risks. Our comprehensive model identified evoked affect (perceived disgust) and naturalness as two crucial predictors of attitudes. These two predictors also act as substantial mediators of perceived benefits, and they activate the mediation of perceived risks (an insignificant mediator in cognitive processing). In addition, perceived naturalness mediates the name-framing effect mainly through perceived disgust. Our findings have implications for future strategies for communicating about novel foods (like CM) to the public.

RESUMO

One novel strategy to shift food choices in digital shopping environments is to automatically recommend healthier alternatives when an unhealthy choice is made. However, this raises the question which alternative products to recommend. This study assesses 1) whether healthier food swap recommendations are effective, even though the unhealthy choice was made in the presence of visible FOP nutrition labels, and 2) how the similarity of the alternatives influences the acceptance of food swap recommendations. Based on a pre-test, similarity of the recommendation was operationalized in terms of animal-based versus plant-based options. A randomized controlled trial (healthy food swap recommendation conditions: none, similar animal-based, dissimilar plant-based, or mixed animal- and plant-based) with 428 Dutch participants was conducted in a simulated online supermarket. Additional healthier food swap recommendations improved the nutritional quality of the final basket compared to only providing Nutri-Score nutrition labels (-1.7 mean FSA score, p < .001, medium Cohen's d = -0.48). Compared to the dissimilar condition, acceptance of an alternative was more likely in the mixed (odds-ratio = 2.78, p = .015) and in the similar condition (odds-ratio = 2.24, p = .048), but the nutritional quality of the final basket did not differ between treatment conditions. Individuals in treatment conditions who did not receive any recommendation (i.e. only made healthy choices) had higher Nutri-Score familiarity and general health interest than individuals who received recommendations. This suggests that for individuals with higher knowledge and motivation FOP nutrition labels were sufficient, whereas for individuals with lower knowledge and motivation additional food swap recommendations can improve dietary choices. Food swap recommendations may act as meaningful reminders by disrupting the automatic choice process and triggering individuals to rethink their (unhealthy) choice.

RESUMO

This study aims to identify opportunities and barriers in developing and implementing Food Shopping Support Systems (FSSS) for healthier and more sustainable choices, given the growing consumer demand and persistent societal problems related to food. The study examined the social and technical value of FSSS in an early development stage through one-on-one expert interviews (n = 20) and consumer focus groups (4 groups, n = 19). Experts were employed in the fields of behavioral sciences, digital marketing, decision aids, software development, persuasive technologies, and public health and sustainability. Consumer participants were used to shopping online. Through a card sorting task followed by semi-structured interview questions, responses were elicited. Participants were presented with 17 cards in 5 rounds, each addressing a different topic related to decision support. Results show that support is perceived useful, particularly when suggestions are personalized, transparent, and justified (using labelling or informative text). Opportunities for uptake were presenting suggestions early in the shopping trip in a visible but non-disruptive manner, allowing autonomy to choose the type of guidance (e.g., show sustainable but not healthier suggestions) and to (not) provide personal data, and educating consumers. Negative attitudes were associated with support being disruptive or steering, being of low credibility, and unclarity about what is healthy or sustainable. Consumer participants expressed concerns about too generic suggestions in relation to health and lack of knowledge about labelling. They emphasized that excessive support and required effort, such as repeatedly providing data, can be burdensome. Experts also worried about limited consumer interest and not having the required data to provide support. Results from this study reveal the potential for successful digital interventions to encourage healthier and more sustainable choices and what this means for further development.

RESUMO

BACKGROUND: Online grocery stores offer opportunities to encourage healthier food choices at the moment that consumers place a product of their choice in their basket. This study assessed the effect of a swap offer, Nutri-Score labeling, and a descriptive norm message on the nutrient profiling (NP) score of food choices in an online food basket. Additionally explored was whether these interventions made it more motivating and easier for consumers to select healthier foods and whether potential effects were moderated by consumer health interest. METHODS: Hypotheses were tested with a randomized controlled trial (RCT) in a simulated online supermarket. Dutch participants (n = 550) chose their preferred product out of six product options for four different categories (breakfast cereals, crackers, pizza, and muesli bars). Participants were randomly allocated to one of eight groups based on the interventions in a 2 (Nutri-Score: present, not present) X 2 (swap offer: present, not present) X 2 (norm message: present, not present) between subject design. The primary outcome was the difference in combined NP score of product choices, for which a lower score represented a healthier product. RESULTS: Swap offer (B = - 9.58, 95% CI: [- 12.026; - 7.132], È 2 = 0.098) and Nutri-Score labeling (B = - 3.28, 95% CI: [- 5.724; -.829], È 2 = 0.013) significantly improved the combined NP score compared to the control condition (NP score M = 18.03, SD = 14.02), whereas a norm message did not have a significant effect (B = - 1.378, 95% CI [- 3.825; 1.070], È 2 = 0.002). No evidence was found that interventions made it more motivating or easier for consumers to select healthier food, but situational motivation significantly influenced the healthiness score of food choices for both swap offer (b = - 3.40, p < .001) and Nutri-Score (b = - 3.25, p < .001). Consumer health interest only significantly moderated the influence of Nutri-Score on ease of identifying the healthy food option (b = .23, p = .04). CONCLUSIONS: Swap offer and Nutri-Score labeling were effective in enhancing healthy purchase behavior in the online store environment. TRIAL REGISTRATION: This study was retrospectively registered in the ISRCTN database on 02-09-2021 ( ISRCTN80519674 ).

RESUMO

Concern about the welfare of production animals is growing among various stakeholders, including the general public. Citizens can influence the market for premium welfare products by expressing public concerns, and consumers-the actors who actually purchase products-can do so through their purchasing behavior. However, current market shares for premium welfare products are small in Europe. To better align purchase behavior with public and individuals' concerns, insight is needed into determinants that influence the intention to purchase premium welfare products. A cross-sectional online survey of 787 Flemish milk consumers was conducted to investigate attitudes toward and intention to purchase animal-friendly milk. More than half of the sample (52.5%) expressed the intention to purchase animal-friendly milk. Linear regression modeling indicated that intention was positively influenced by (1) higher perceived product benefits from animal-friendly milk (milk with more health benefits and higher quality); (2) higher personal importance of extrinsic product attributes such as local production and country of origin; (3) higher personal importance of animal welfare; (4) a more natural living oriented attitude toward cows; and (5) a more positive general attitude toward milk. Intention was negatively influenced by (1) a stronger business-oriented attitude toward cows; and (2) by a higher personal importance attached to price. These insights in key components of purchase intention can assist producers, the dairy industry, and retailers to position and market animal-friendly milk.

RESUMO

Intensive agricultural practices and current western consumption patterns are associated with increased ecological pressure. One way to reduce the ecological impact could be a shift to more sustainable food choices. This study investigates consumer opinions towards a series of food choices with a lower ecological impact. The investigated food choices range from well-known meat substitutes to alternatives which are more radical or innovative and that require an adaptation of food habits and cultural patterns. Results are obtained through a survey among 221 Flemish respondents in Spring 2011. Many consumers underestimate the ecological impact of animal production. Well-known alternatives such as organic meat, moderation of meat consumption and sustainable fish are accepted, although willingness to pay is clearly lower than willingness to consume. Consumers are more reluctant to alternatives that (partly) ban or replace meat in the meal. Opportunities of introducing insects currently appear to be non-existent. Five consumer segments were identified based on self-evaluated ecological footprint and personal relevance of the ecological footprint. The segments were termed Conscious, Active, Unwilling, Ignorant and Uncertain. A profile in terms of demographics, attitudinal and behavioral characteristics is developed for each segments, and conclusions with respect to opportunities for sustainable food choices are discussed.

RESUMO

The segment of organic products occupies an increasingly important place in dairy assortments. The European Union (EU) introduced a new EU organic logo in 2010 with the aim of harmonizing its organic sector and boosting consumer trust in organic food. This study focuses on organic yogurt and investigates consumer awareness and knowledge of the new EU logo. Consumers evaluate organic yogurt as superior compared with conventional yogurt on healthiness, environmental friendliness, quality, and safety. More frequent buyers of organic yogurt have a stronger belief that organic yogurt is superior. The willingness-to-pay for organic yogurt ranged from a premium of 15% for nonbuyers to 40% for habitual buyers, indicating the market potential for this product. A structural equations model reveals the positive association between knowledge, attitudes, and the frequency of purchasing and consuming organic yogurt. Nevertheless, consumer awareness of the EU organic logo remains rather low, which suggests a need for more effective information campaigns and marketing actions.

RESUMO

This research investigates the attitudes and intentions of Chinese consumers about cultured "meat" (CM). We also investigate framing effects through the names used for these products ("cultured meat," "artificial meat," and "cell-based meat") and the effect of information provision. Of the 1532 consumers in our sample, most had not heard of "cultured meat" or "cell-based meat" before, although 70% had heard of "artificial meat". Around 44% of the participants indicated that they would be willing to try CM, and 32% would be likely to purchase it. Participants disliked the terms "cultured meat" and "cell-based meat" less than they disliked the term "artificial meat," although the latter was the most familiar to them. The provision of neutral information on the production process increased consumer support for CM, but the effect was limited. Prior knowledge and naming terms were strong predictors of attitudes and willingness to buy. A key implication is that stakeholders should cautiously apply framing strategies when introducing CM to the public.

RESUMO

Overweight, obesity and cardiometabolic diseases are major global health concerns. Lifestyle factors, including diet, have been acknowledged to play a key role in the solution of these health risks. However, as shown by numerous studies, and in clinical practice, it is extremely challenging to quantify dietary behaviors as well as influencing them via dietary interventions. As shown by the limited success of 'one-size-fits-all' nutritional campaigns catered to an entire population or subpopulation, the need for more personalized coaching approaches is evident. New technology-based innovations provide opportunities to further improve the accuracy of dietary assessment and develop approaches to coach individuals towards healthier dietary behaviors. Pride & Prejudice (P&P) is a unique multi-disciplinary consortium consisting of researchers in life, nutrition, ICT, design, behavioral and social sciences from all four Dutch Universities of Technology. P&P focuses on the development and integration of innovative technological techniques such as artificial intelligence (AI), machine learning, conversational agents, behavior change theory and personalized coaching to improve current practices and establish lasting dietary behavior change.

RESUMO

This study evaluates the attitudes and perspectives of different stakeholder groups (agricultural producers, pesticide manufacturers, trading companies, retailers, regulators, food safety authorities, scientists and NGOs) towards the concepts of cumulative and aggregate exposure assessment of pesticides by means of qualitative in-depth interviews (n = 15) and a quantitative stakeholder survey (n = 65). The stakeholders involved generally agreed that the use of chemical pesticides is needed, primarily for meeting the need of feeding the growing world population, while clearly acknowledging the problematic nature of human exposure to pesticide residues. Current monitoring was generally perceived to be adequate, but the timeliness and consistency of monitoring practices across countries were questioned. The concept of cumulative exposure assessment was better understood by stakeholders than the concept of aggregate exposure assessment. Identified pitfalls were data availability, data limitations, sources and ways of dealing with uncertainties, as well as information and training needs. Regulators and food safety authorities were perceived as the stakeholder groups for whom cumulative and aggregate pesticide exposure assessment methods and tools would be most useful and acceptable. Insights obtained from this exploratory study have been integrated in the development of targeted and stakeholder-tailored dissemination and training programmes that were implemented within the EU-FP7 project ACROPOLIS.

RESUMO

Both cisgenesis and transgenesis are plant breeding techniques that can be used to introduce new genes into plant genomes. However, transgenesis uses gene(s) from a non-plant organism or from a donor plant that is sexually incompatible with the recipient plant while cisgenesis involves the introduction of gene(s) from a crossable--sexually compatible--plant. Traditional breeding techniques could possibly achieve the same results as those from cisgenesis, but would require a much larger timeframe. Cisgenesis allows plant breeders to enhance an existing cultivar more quickly and with little to no genetic drag. The current regulation in the European Union (EU) on genetically modified organisms (GMOs) treats cisgenic plants the same as transgenic plants and both are mandatorily labeled as GMOs. This study estimates European consumers' willingness-to-pay (WTP) for rice labeled as GM, cisgenic, with environmental benefits (which cisgenesis could provide), or any combination of these three attributes. Data were collected from 3,002 participants through an online survey administered in Belgium, France, the Netherlands, Spain and the United Kingdom in 2013. Censored regression models were used to model consumers' WTP in each country. Model estimates highlight significant differences in WTP across countries. In all five countries, consumers are willing-to-pay a premium to avoid purchasing rice labeled as GM. In all countries except Spain, consumers have a significantly higher WTP to avoid consuming rice labeled as GM compared to rice labeled as cisgenic, suggesting that inserting genes from the plant's own gene pool is more acceptable to consumers. Additionally, French consumers are willing-to-pay a premium for rice labeled as having environmental benefits compared to conventional rice. These findings suggest that not all GMOs are the same in consumers' eyes and thus, from a consumer preference perspective, the differences between transgenic and cisgenic products are recommended to be reflected in GMO labeling and trade policies.

RESUMO

The organic meat industry in the United States has grown substantially in the past decade in response to consumer demand for nonconventionally produced products. Consumers are often not aware that the United States Department of Agriculture (USDA) organic standards are based only on the methods used for production and processing of the product and not on the product's safety. Food safety hazards associated with organic meats remain unclear because of the limited research conducted to determine the safety of organic meat from farm-to-fork. The objective of this review is to provide an overview of the published results on the microbiological safety of organic meats. In addition, antimicrobial resistance of microbes in organic food animal production is addressed. Determining the food safety risks associated with organic meat production requires systematic longitudinal studies that quantify the risks of microbial and nonmicrobial hazards from farm-to-fork.

RESUMO

Liquid smoke extracts have traditionally been used as flavoring agents, are known to possess antioxidant properties, and serve as natural alternatives to conventional antimicrobials. The antimicrobial efficacies of commercial liquid smoke samples may vary depending on their source and composition and the methods used to extract and concentrate the smoke. We investigated the MICs of eight commercial liquid smoke samples against Salmonella Enteritidis, Staphylococcus aureus, and Escherichia coli . The commercial liquid smoke samples purchased were supplied by the manufacturer as water-based or concentrated extracts of smoke from different wood sources. The MICs of the commercial smokes to inhibit the growth of foodborne pathogens ranged from 0.5 to 6.0% for E. coli, 0.5 to 8.0% for Salmonella, and 0.38 to 6% for S. aureus. The MIC for each liquid smoke sample was similar in its effect on both E. coli and Salmonella. Solvent-extracted antimicrobials prepared using pecan shells displayed significant differences between their inhibitory concentrations depending on the type of solvent used for extraction. The results indicated that the liquid smoke samples tested in this study could serve as effective natural antimicrobials and that their inhibitory effects depended more on the solvents used for extraction than the wood source.

RESUMO

International attention has been focused on minimizing costs that may unnecessarily raise food prices. One important aspect to consider is the redundant and overlapping costs of food safety audits. The Global Food Safety Initiative (GFSI) has devised benchmarked schemes based on existing international food safety standards for use as a unifying standard accepted by many retailers. The present study was conducted to evaluate the impact of the decision made by Walmart Stores (Bentonville, AR) to require their suppliers to become GFSI compliant. An online survey of 174 retail suppliers was conducted to assess food suppliers' opinions of this requirement and the benefits suppliers realized when they transitioned from their previous food safety systems. The most common reason for becoming GFSI compliant was to meet customers' requirements; thus, supplier implementation of the GFSI standards was not entirely voluntary. Other reasons given for compliance were enhancing food safety and remaining competitive. About 54 % of food processing plants using GFSI benchmarked schemes followed the guidelines of Safe Quality Food 2000 and 37 % followed those of the British Retail Consortium. At the supplier level, 58 % followed Safe Quality Food 2000 and 31 % followed the British Retail Consortium. Respondents reported that the certification process took about 10 months. The most common reason for selecting a certain GFSI benchmarked scheme was because it was widely accepted by customers (retailers). Four other common reasons were (i) the standard has a good reputation in the industry, (ii) the standard was recommended by others, (iii) the standard is most often used in the industry, and (iv) the standard was required by one of their customers. Most suppliers agreed that increased safety of their products was required to comply with GFSI benchmarked schemes. They also agreed that the GFSI required a more carefully documented food safety management system, which often required improved company food safety practices and increased employee training. Adoption of a GFSI benchmarked scheme resulted in fewer audits, i.e., one less per year. An educational opportunity exists to acquaint retailers and suppliers worldwide with the benefits of having an internationally recognized certification program such as that recognized by the GFSI.
