ABSTRACT: Nutrigenomics is a new and promising development in nutritional science which aims to understand the fundamental molecular processes affected by foods. Despite general agreement on its promise for better understanding diet¿health relationships, less consensus exists among experts on the potential of spin-offs aimed at the consumer such as personalised nutrition. Research into consumer acceptance of such applications is scarce. The present study develops a set of key hypotheses on public acceptance of personalised nutrition and tests these in a representative sample of Dutch consumers. An innovative consumer research methodology is used in which consumers evaluate short films which are systematically varied scenarios for the future of personalised nutrition. Consumer evaluations of these films, which are pre-tested in a pilot study, allow a formal test of how consumer perceptions of personalised nutrition drive consumer acceptance and through which fundamental psychological processes these effects are mediated. Public acceptance is enhanced if consumers can make their genetic profile available free at their own choice, if the actual spin-off products provide a clearly recognisable advantage to the consumer, and are easy to implement into the daily routine. Consumers prefer communication on nutrigenomics and personalised nutrition by expert stakeholders to be univocal and aimed at building support with consumers and their direct environments for this intriguing new development. Additionally, an exploratory segmentation analysis indicated that people have different focal points in their preferences for alternative scenarios of personalised nutrition. The insights obtained from the present study provide guidance for the successful further development of nutrigenomics and its applications.

ABSTRACT: Methods of production are becoming more important to consumers in their decisions about whether or not to buy or consume a certain product. This decision making process is influenced, among other things, by the images consumers have with regard to the product and its method of production. In this research, consumer images regarding plant breeding technologies were ascertained by means of focus group discussions. Thirty-five respondents, divided into four homogenous groups, were given descriptions of three plant breeding techniques and challenged to provide and discuss their images of these technologies. The discussions resulted in images about genetic modification, genomics, and conventional breeding. It was interesting to see that elaboration of the descriptions changed the consumers¿ images, especially regarding the positioning of genomics in relation to the other two technologies. Whereas initially consumers¿ images placed genomics close to genetic modification, further discussion and clarification resulted in a re-positioning of genomics closer to conventional breeding.

ABSTRACT: Understanding of the determinants of consumer confidence in the safety of food is important if effective risk management and communication are to be developed. In the research reported here, we attempt to understand the roles of consumer trust in actors in the food chain and regulators, consumer recall of food safety incidents, consumer perceptions regarding the safety of particular product groups, personality characteristics, and sociodemographics, as potential determinants of consumer confidence in the safety of food. Consumer confidence in the safety of food was conceptualized as consisting of two distinct dimensions, namely, "optimism" and "pessimism." On the basis of a representative sample of 657 Dutch consumers, structural equation modeling was applied to simultaneously estimate the effect of the determinants on both "optimism" and "pessimism." The results indicated that, to a considerable extent, both optimism and pessimism about the safety of food arise from consumer trust in regulators and actors in the food chain and the perceived safety of meat and fish rather than other product categories. In addition, support was found for the notion that optimism and pessimism are conceptually distinct, as these dimensions of confidence were partly influenced by different determinants. The results of this study imply that consumer confidence in the safety of food could be enhanced by improving both consumer trust in societal actors, and consumer safety perceptions of particular product groups.

ABSTRACT: Determinants of consumer adoption of innovations have been studied from different angles and from the perspectives of various disciplines. In the food area, the literature is dominated by a focus on consumer concern. This paper reviews previous research into acceptance of technology-based innovation from both inside and outside the food domain, extracts key learnings from this literature and integrates them into a new conceptual framework for consumer acceptance of technology-based food innovations. The framework distinguishes `distal¿ and `proximal¿ determinants of acceptance. Distal factors (characteristics of the innovation, the consumer and the social system) influence consumers¿ intention to accept an innovation through proximal factors (perceived cost/benefit considerations, perceptions of risk and uncertainty, social norm and perceived behavioural control). The framework's application as a tool to anticipate consumer reaction to future innovations is illustrated for an actual technology-based innovation in food science, nutrigenomics (the interaction between nutrition and human genetics).

ABSTRACT: Information regarding the method of production of food products influences the decision-making process of consumers. The aim of this study is investigate to what extent information about genomics biases consumer decision making. We investigate the exact source of the biasing nature by separating the effect on consumer beliefs and the salience of those beliefs. The effect of information is tested through an information condition concerning two breeding methods, namely classical breeding and breeding enabled by genomics. The results show that consumer preferences are influenced by the information on production technology. More specifically, the consumer preferences change because consumers alter the salience of their beliefs towards the product.

ABSTRACT: The Quality Guidance Model was extended beyond sensory properties to include credence motivations like healthiness, environmental friendliness, naturalness, and safety. This Extended Quality Guidance Model was built and tested to explain consumer preferences from consumer perceptions, expert sensory judgments, and metabolite features of tomatoes. The different type of features (sensory, technical, and consumer perceptions) made it possible to explore the actionability of the features in predicting consumer preferences both in-store and upon consumption.

ABSTRACT: Abstract: In response to the potential for negative economic and societal effects resulting from a low level of consumer confidence in food safety, it is important to know how confidence is potentially influenced by external events. The aim of this article is to describe the development of a monitor that enables changes in consumer confidence in food safety and consumer food choice behaviour to be assessed in conjunction with changes in institutional activities and food safety incidents. Results of the first assessment of longitudinal data on consumer perceptions of food safety will be presented to provide the basis for the development of such a monitor. A better understanding of the interrelationships between antecedents and behavioural consequences of changes in consumer confidence in food safety over time will improve understanding of the effectiveness of public policy, and allow the development of best practice in risk communication and risk management.
