Product attributes and consumer acceptance of nutritionally enhanced genetically modified foods

Using data from a national survey, this study analyses US consumers’ acceptance of genetically modified foods that provide additional nutritional benefits. Using an ordered probit model, this study examines the relation between the willingness to consume genetically modified foods and consumers’ economic, demographic and value attributes. Empirical results suggest that despite having some reservations, especially about the use of biotechnology in animals, American consumers are not decidedly opposed to food biotechnology. Consumers’ economic and demographic variables are only weakly related to their acceptance of food biotechnology, especially when technology involves plant‐to‐plant DNA transfer. However, public trust and confidence in various private and public institutions are significantly related to their acceptance of food biotechnology. Overall, consumer acceptance of bioengineered foods is driven primarily by public perceptions of risks, benefits and safety of these food products.     

Foods produced using biotechnology: how does the law protect consumers?

This paper addresses the following subjects: biotechnology and consumers, concern about risks, consumer acceptance, labelling of foods produced using biotechnology, the legal approach to consumer protection, and consumer protection policies relating to biotechnology products in the European Union, the United States, Turkey and global institutions such as the Convention for Biological Diversity (CBD) and the World Trade Organisation (WTO). It is likely that biotechnology will gain ground much more rapidly in the twenty‐first century than in the past. Despite rapid, detailed and precise advances in gene technology, its applications have not been the received with a great deal of consumer enthusiasm. Consumers have approached genetically modified foods with considerable apprehension and opposition. Consumer concerns about bioengineered food products focus on the questions of human health, environmental and social risks and benefits. The most important stages in the process of marketing new foods produced using biotechnology are to demonstrate user need and consumer acceptance. Generally, the technical complexity of biotechnology makes it difficult for consumers to understand details of the product and the specific attributes of biotechnology applications. Scientific uncertainty, the nature of consumer concerns and general reluctance to accept biotechnology products, increase the importance of consumer protection. Legal protection is a very important factor in the solution of new social problems related to technological advances. More specifically, consumer and environmental law support consumer protection related to foods produced with biotechnology. The basic principles of consumer law can be re‐formulated as consumer rights. Environmental law is a new phenomenon, but precautionary principles and public participation in decision‐making for environmental law are relevant to consumer protection relating to bioengineered food products.     

Acceptance of Genetically Modified Foods with Health Benefits: A Study in Germany

A study was carried out in Germany in order to assess consumers' acceptance of genetically modified (GM) foods with health benefits (bread, yohurt and eggs). Acceptability of GM foods increases when its source does not involve animal products such as eggs. Three factors have been identified as direct antecedents of the acceptance of GM foods: respondents' attitude towards biotechnology, health consciousness, and time pressure, being the first one the most salient one. Price consciousness has an indirect positive impact (mediated by health consciousness) upon acceptance of GM products. Males were more likely to accept GM foods with health benefits.     

Genetically Modified Foods

ABSTRACT

This study outlines the controversy surrounding genetically modified organisms (GMOs) and how it impacts North American based food service companies' marketing policies. Recent developments have made foods derived from GMOs a strategic marketing challenge for food service franchise and chain operations. Headlines such as “Why McDonalds Pulled Frankenfries from Menus” have unwittingly put restaurants on the frontline of the battle over foods made from GMOs (Martin, 2000). A survey method was used to explore food service operations' views regarding consumer acceptance of GMOs, right to know issues (labeling) and the benefits of GMOs, as well as food service companies' strategic response to this emerging technology. Findings indicate that food service establishments were generally concerned about customer opinions and tend to prefer government mandated labeling of GMOs. They also tend to feel that GMOs offer potential benefits to their industry and that customer concerns may fade over time.     

Gender differences in consumers’ acceptance of genetically modified foods

Research has shown that women are less accepting of genetically engineered products than men. We expect two mechanisms to be at work here. First, in consumer behaviour theory, more knowledge is assumed to lead to more acceptance. We assumed that for genetically engineered foods, this general principle does not apply since long‐term consequences are not known yet. The well‐informed consumer is likely to be comparatively more concerned with this lack of knowledge. We call this the information paradox. Theory on the topic is relatively recent. The results of this study will help to distinguish consumer behaviour with regard to new types of food as compared with traditional foods. Second, we assumed that there is a gender factor included in attitudes toward foods. In general, women still plan food and household purchases. A tentative attitude and an accompanying reluctance toward food innovation are adopted when buying food for children. We call this the gender paradox. In this exploratory study we use data from the Eurobarometer. Eurobarometer surveys have been executed since 1973 by the European Commission among the adult population of European Union member countries (n > 10 000), monitoring the evolution of public opinion. Analysis of these surveys shows that gender differences exist in the acceptance of genetically modified (GM) foods in Europe. Women tend to be less accepting toward genetically modified foods. This supports our gender hypothesis. However, no evidence was found to support the assumed information paradox. It seems that knowledge leads to acceptance, also of GM foods, but more so for men than for women.     

Debunking the myth of general consumer rejection of green genetic engineering: Empirical evidence from Germany

The emergence of a more sustainable economy in Europe was accompanied by a range of bio‐based products and technologies. As a prominent example, green genetic engineering opens up multiple options to increase agricultural production, but its public acceptance seems to vary by application area. Risk perception explains consumer acceptance of green genetic engineering, which is a necessary precondition for wider technology adoption. This study investigates risk perceptions for four major sources of risk: health related, environmental, socioeconomic and ethical. Data were collected in a laboratory experiment in Germany, with a total of 439 participants. A between‐subject design was employed. The four experimental treatment groups comprised two policy scenarios, namely one only permitting research and development and the other allowing full commercialization of genetically modified products, and two product end‐uses, bioenergy and food. The study shows significant end‐use differences in both the type of policy scenario and the risk dimension in question. In particular, health risks were generally perceived to be lower for bioenergy than food whenever full commercialization was pursued. Furthermore, full commercialization of genetically modified food prompted higher concerns about personal health, whereas use of crops for bioenergy production was broadly related to higher levels of socioeconomic risk. Finally, although the majority of consumers identified health risks as being most relevant, the consequences for the environment evoked the greatest degree of risk perception. In general, our findings lend support for the notion that the policy regime is the most important determinant for risk perception, followed by the type of risk dimension and level of trust in industry.

Genetically modified foods: Consumer awareness,opinions and attitudes in selected EU countries

The dynamic development of biotechnology in recent years has raised serious public concerns about the possible risks arising from genetically modified organisms (GMOs). The aim of this study was to investigate consumer opinions regarding genetically modified (GM) foods. The research also aimed at verifying the differences in the attitudes of respondents from two, relatively culturally diverse research sites. To obtain empirical data a face‐to‐face survey was conducted in 2015. It covered a total of 976 randomly selected individuals. The study was performed in the capital of the United Kingdom—London and the Polish capital—Warsaw. The results of the study show that almost half of the respondents were familiar with the GMO concept. According to the respondents, the greatest benefits arising from the genetic modification are: enhanced shelf‐life of food and crops' resistance to extreme climatic conditions. The main disadvantages were: unpredictable consequences of deoxyribonucleic acid (DNA) modification, production of species‐specific toxins and food allergenicity. Over two thirds of people surveyed support the idea of the obligatory labeling of GM foods. The information presented on food packaging should primarily include potential contraindications to the consumption, indication that food was produced using transgenic sources and a warning about potential allergenicity. An almost equal number of respondents showed intention for purchasing GM food products, an intention to act otherwise, or was not decided. As many as 27.7% of survey participants showed negative attitudes toward GM foods, whereas only 19.8% predominantly positive. It is worth noticing that, with only one exception, no statistically significant differences were observed between the opinions of Polish and British respondents.     

Consumer involvement and acceptance of biotechnology in the European Union: a specific focus on Spain and the UK

Biotechnology stands out as a clear‐cut example of an industry where legislation on new technologies has been shown to be linked with public attitudes. Indeed, consumer consultation has played a leading role in the acceptance of genetically modified (GM) food as well as in government policy and legislation. This paper examines the issue of consumer consultation by analysing how public opinion has conditioned the acceptance of GM food in the European Union in general and specifically in Spain and the UK. We draw upon the evidence of two Eurobarometer surveys (46.1 and 52.1) to argue that consumer decision making on new technologies is an information‐dependent factor explaining consumer rejection to non‐transparent introduction of GM food. Individuals feel ill‐prepared to make decisions and rely on trusted information advisors such as consumer organizations. Findings suggest significant information dependency as well as widespread heterogeneity in attitudes towards the applications of biotechnology. Finally, the role played by information channels indicates that consumer participation should precede the adoption of communication policies, as they might need to adapt to the specific cultural characteristics of each country.     

Perceptions and Attitudes of Singaporeans towards Genetically Modified Food

This study examines the perceptions and attitudes of Singaporean residents who attended the first public lecture on genetically modified (GM) food in the country. Scales were developed for the underlying consumer concerns, and their relationship with one another and with demographic variables were examined. Slightly more than half of those who attended the talk (n= 417) indicated that they were worried about GM foods and 86 percent agreed or strongly agreed that GM foods should be labeled. Issues relating to health, ethics, and perceived benefits were the major underlying concerns. These were related to several demographic variables and also to perceived knowledge about biotechnology. Women were more concerned about the ethical and health aspects compared to men. Those with post‐graduate education were the least concerned about health and ethical issues and more likely to buy GM foods if consumer benefits are shown. Married respondents were less concerned about health issues compared to single ones. Also, those with children under fifteen years of age were less concerned about health issues compared to others and more likely to buy GM foods if consumer benefits are shown. Respondents subscribing to the Hindu religion were more likely than others to buy GM foods If benefits are shown. Also, those who considered themselves vegetarians were more concerned about the ethical aspects of GM foods compared to others.     

An Open Mind Wants More: Opinion Strength and the Desire for Genetically Modified Food Labeling Policy

Two opposing viewpoints exist in the literature; some suggest consumers are unconcerned and do not desire any genetically modified labeling, while others indicate the opposite. The mixed results may be because consumers make finer distinctions than surveys have called for, and have evaluation schemes sensitive to information about the benefits and risks associated with genetically modified foods. We find consumers are quite nuanced in their preferences for genetically modified labeling policy. Unexpectedly, consumers with less‐defined views desire mandatory labeling of the most stringent type, while consumers with stronger viewpoints (either pro‐ or con‐genetically modified) are more relaxed in their labeling requirements.     

Consumer Buying Behavior of Genetically Modified Fries in Germany

A purchasing experiment in which genetically modified and conventional fries were offered for sale at mobile fast food stands in Germany was conducted to identify factors influencing the willingness of consumers to purchase genetically modified fries. In total, 331 purchasing decisions were made: 56.5% decided to purchase conventional fries, 22.4% genetically modified fries, and 21.1% no preference. A logistic regression model analyzing questionnaires found that worry about pesticides, frequency of organic food purchases, the acceptability of genetically modified foods with environmental benefits, and perceptions of health risks from genetically modified foods significantly impact the willingness to purchase genetically modified fries.     

Labelling genetically modified food products: consumers’ concern in the United Kingdom

An online survey method was used to collect data regarding the concern and attitude of UK consumers towards genetically modified (GM) food labelling. Questionnaires were sent to 9000 participants of the online panel via emails, and 2568 consumers completed the online survey. The response rate was 29%. This study found that more than 75% of the consumers questioned were concerned about the labelling of food products with GM ingredients. Eight perceived risks and benefits of agro‐biotechnology were identified to be associated with consumers’ attitude towards GM food labelling. Among them, three were perceived benefits, such as reduced use of chemicals in crop production, improved nutritional content, and increased yields. The five perceived risks were health risks, environmental risks, moral considerations, image of multinational corporations as the primary beneficiaries of biotechnology, and growing control of multinational corporations over farming. While all five perceived risks from GM food played a statistically significant role in shaping the overall attitude towards GM labelling, improved nutritional content due to application of biotechnology was the only benefit that was statistically significant. Age of the respondents was the only demographic variable playing a statistically significant role in shaping the attitude of respondents towards GM food labelling. Older respondents were more likely to be concerned about the existing GM labelling practices than younger respondents.     

The effect of knowledge types on consumer‐perceived risk and adoption of genetically modified foods

Scientists have asserted that genetically modified (GM) food offers financial, environmental, health, and quality benefits to society, but the realization of such benefits depends on consumer acceptance of this new technology. Consumer concerns about GM food raise questions about what consumers know about GM food and to what extent this knowledge translates into their evaluations of GM products. The present research empirically examines the effect of both objective and subjective knowledge on perceived risk and, in turn, key consumer behaviors associated with GM food. The results reveal that objective knowledge about GM food significantly reduces performance and psychological risks, whereas subjective knowledge influences only physical risk, and the valence of that impact depends on the level of the consumer's objective knowledge. Furthermore, different risk types enhance consumers' information search and reduce their propensity to buy GM food. The overall findings thus suggest the need for cooperation among government, scientific institutions, and the food industry to foster effective communication strategies that increase consumers' objective knowledge, reduce their risk perceptions, and encourage consumer adoptions of GM technology. © 2007 Wiley Periodicals, Inc.     

Determinants of Consumer Attitudes and Purchase Intentions With Regard to Genetically Modified Food – Results of a Cross-National Survey

Previous research has shown consumers to be highly sceptical towards genetic modification in food production. So far, however, little research has tried to explain how consumers form attitudes and make decisions with regard to genetically modified foods. The paper presents the results of a survey which was carried out in Denmark, Germany, Italy, and the United Kingdom to investigate the formation of consumer attitudes towards genetic modification in food production and of purchase decisions with regard to genetically modified yoghurt and beer. Altogether, 2031 consumers were interviewed in the four countries.Results show that attitude formation and decision-making are more comparable among Danish, German, and British consumers than with Italian consumers. Italian consumers turned out to be significantly less negative towards genetic modification in foods than particularly Danish and German consumers. Across countries, the attitude towards genetic modification in food production was deeply embedded in more general attitudes held by the consumers, in particular attitude towards nature and attitude towards technology. These general attitudes were found to influence perceived risks and benefits of the technology. Purchase decisions with regard to the two product examples were almost exclusively determined by attitudes towards purchasing the products. These were, in turn, significantly influenced by the overall attitude towards genetic modification in food production through their effects on beliefs held by consumers regarding the quality and trustworthiness of the products.The results suggest that attitudes towards genetically modified foods are quite strong, despite their lack of basis in actual product experience. Likewise, the strong relation of product-specific attitudes to the attitude towards using genetic modification in food production suggests that at present consumers reject the technology overall rather than evaluate products on a case-by-case basis. This situation may, however, be changed by a possible increased availability of genetically modified food products on the consumer market.     

Finns and functional foods: socio‐demographics,health efforts,notions of technology and the acceptability of health‐promoting foods

Eating is increasingly characterized by concerns over health and well‐being. New types of foods designed to promote health or to reduce the risk of diseases, known as functional foods, have been entering the market since the 1990s. This article focuses on the appropriation of functional foods among Finnish consumers from the perspective of acceptability. We analyse the relationship between consumers’ views of functional foods and their socio‐demographic backgrounds, health efforts and notions of food, health and technology. The article is based on a survey of a representative sample of Finnish consumers (n = 1210). The data were collected by using computer‐assisted telephone interviews and analysed by factor analysis and analysis of variance. The factor analysis resulted in four dimensions of acceptability: (1) experiences of functional foods; (2) views on product quality and safety; (3) societal concerns over current developments; and (4) views on regulation and research. According to the results, the differences in consumer views of functional foods were to some extent linked with age and education but better explained by the differing roles of food and health in people’s lives and the acceptability of modern food technologies. Efforts to lower blood cholesterol and/or blood pressure, the use of dietary supplements, regarding healthy eating as very important and having an optimistic outlook on the use of technology in food production were all related to more optimistic views of functional foods. Finns seem to have a relatively trusting position on functional foods. Familiarity of functional foods in Finland, absence of serious food scandals, the health‐oriented Finnish culture and the generally high level of societal trust may account for this optimism.     

Biotechnology in the agricultural sector: a challenge to consumer welfare

The promises and pitfalls of agricultural biotechnology have long been debated. The public is often thwarted because consumers frequently perceive as risky, and therefore undesirable, those advances that they do not understand or of which they are unaware. A comparative study of the introduction of a biotechnology innovation in the United States (US) and in the European Union (EU) is a case in point. In the US, despite concerns of consumer protection and environmental groups that the use of genetically produced growth hormone in milk‐producing cows will adversely impact the safety of the milk supply, scientific evidence and governmental findings appear to indicate that milk from treated cows is identical in quality, taste and nutritional value to milk from untreated cows. Experience to date in the US demonstrates some consumer resistance to milk from those cows that have received the growth hormone, which typically leads to a 10% increase in milk production. In fact, if there is no perceived differentiation between the two forms of milk, the issue offers little choice to consumers at large, and may result in economic benefit only to selected dairy farmers, as well as the producers of the genetically produced growth hormone. This situation in the US is an example of dysfunctional technology transfer, with perceived desirable benefits to a few, and perceived undesirable benefits to society‐at‐large. The information suggests that the US may have reacted hastily in approving the use of bovine growth hormone in milk‐producing cows. The EU has taken a divergent approach by enacting moratoriums against its use. The differences identified in this study, contrasting responses to the bovine somatotrophin issue in the US and EU – driven in part by general consumer attitudes towards biotechnology – may provide insights into the issues and challenges that will be faced by both advocates and opponents of global proliferation of certain advances in biotechnology.     

Consumer acceptance of food irradiation: a test of the recreancy theorem

Consumers living in both developed and developing nations rely upon foods that have been produced and processed in many countries and in a wide variety of ways. Therefore, it is not surprising that they express concerns about the safety of their food supplies. A technology proposed to improve consumer trust in food safety is irradiation. Despite extensive education efforts and endorsements given by many health‐related organizations worldwide, food irradiation has been slow to gain widespread acceptance. This ineffectiveness of diffusion efforts might indicate a need to broaden our theoretical perspectives of consumer acceptance of controversial technologies. Most theoretical approaches explain acceptance primarily as a function of perceived risks associated with a technology. The recreancy theorem, in contrast, explains acceptance as a function of public trust in societal institutions to effectively manage a technology. This study investigated the extent to which the recreancy theorem explained acceptance of food irradiation by US consumers, while statistically controlling for perceived risk and social‐demographic variables. The study used a longitudinal field design to survey one adult each in 116 households located in the Minneapolis, Minnesota area during the first large‐scale market test of irradiated food. The results indicate that the recreancy theorem might provide a valid conceptual approach to gaining a broader understanding of consumer acceptance of controversial new technologies.     

A Second Generation of Genetically Modified Food

Abstract

The aim of this research was a cross-cultural investigation of views regarding Genetically Modified Organisms, specifically food crops, to determine if there were significant differences in the views of French and American respondents. In addition, we sought to introduce the issue of possible consumer benefits of second generation GMOs into the research by examining differences in acceptance of value-enhanced GMOs compared with first generation GMOs for both French and American respondents. Both first and second generation GMOs are better accepted by American respondents than by French respondents, but respondents in both countries perceive a direct benefit from second generation GM foods with at least a less negative attitude toward them. In addition, respondents indicated factors which would make it more likely that they would purchase such enhanced GM foods.
