Although governments have implemented regulations to inform consumers on important product properties and protect consumers from deceptive information, empirical research on how consumers perceive, interpret and experience food packages have shown frequently that consumers may be misled by how information is presented and packages are designed. While communication in some domains is strictly regulated (health), claims in other domains are largely free (nature) and do not require substantiation. Subtleties in wording, image use and image style may affect the impressions consumers form. To support consumer decision making, legislators should not only provide rules and regulations that are formally correct, but also consider the effects a message and the way it is communicated (e.g., content, typeface, size, use of images, stylistic features) may have on buyers. While it may be unclear how best to support desirable behaviours, companies that take social responsibility can build on our work to develop their strategy.
Commercial food packages may contain multiple messages. Packaging designers try to integrate all messages into a coherent design. Designers may use text, images or stylistic features, but these mediums may differ in their suitability to communicate specific product benefits. To evaluate the usefulness and effectiveness of these three mediums, we not only obtained consumer evaluations of packaging designs, but we also monitored the designer’s experience during the design process.
For three products (orange juice, muesli bar, plain yogurt) we created three consistent packaging designs communicating a single benefit through all three mediums, which was either a  health,  environmental, or  production, sensory or social claim. Subsequently, we developed inconsistent packages communicating three different messages through the three mediums. In an online survey, each of the 18 package variants was evaluated by 59–92 participants.
Dummy regression analysis suggested that verbal claims had positive effects in communicating healthiness and environmental friendliness but elicited a negative tendency for sensory properties. The images we used indicated a positive effect for communicating worker conditions, but a negative effect for healthiness. Our stylistic elements suggested a positive effect for sensory appeal, but tended to have negative effects for environmental aspects. As regards designer dilemmas, we noticed that some images (e.g., in the medical domain) required specific graphic styles to make them acceptable for commercial use. Our findings suggest that consumers can handle multiple packaging messages, but finding an optimal configuration remains a design challenge.
An increasing number of people tend to eat alone due to social changes and an altered attitude towards cooking and eating practices. Anecdotal reports indicate that solo diners tend to use information and communication technology devices, for example, the smartphone, as part of the eating experience. While lab studies suggest that the devices contribute to an increased high-calorie food intake and decreased feeling of satiety, these studies disregard the everyday experience and motivation of solo diners. We conducted an exploratory study to investigate how solo diners use digital devices as part of their daily eating experience. Semi-structured interviews with solo diners (N = 12) were analyzed using thematic analysis in an inductive approach leading to six themes. The themes focus on (1) the perception of a meal; (2) the experience of a solo diner; (3) the purpose of using an information and communication technology device; (4) the perceived influence of the devices; (5) factors decreasing and increasing the use; (6) and the potential to promote healthier food consumption. Our results indicate that the use of digital devices while eating alone can lead to distraction, being unaware of the food texture and the amount that is eaten. The devices can also induce a positive influence by providing entertainment and mitigating negative emotions like loneliness and boredom. The devices have the potential to contribute to healthy eating practices by providing education and by influencing the speed of eating through elements of sound. Although the use of devices might negatively affect eating behavior, their ubiquitous presence also offers the opportunity to reach specific, vulnerable populations.
Disgust is a strong emotion of aversion. In the context of food, it is often referred to as a guardian of the mouth, preventing close contact with pathogens and the accidental consumption of poisons. However, disgust can also create a certain level of attraction and be part of positive experiences, even in the context of food. In this article, we discuss different ways of using disgust to influence eating behaviour and contribute to healthier food consumption. We outline ten different bridging concepts accompanied by various design exemplars on how to use disgust in the context of critical food design. In addition, we present four different lenses that can help to refine the design concepts.
Food experiences extend beyond the eating of food. They may involve fantasizing about food, perceiving the venue where you buy or consume it, seeing or smelling the food from a distance, touching its package or container, the tools you use to prepare and cook, the cutlery you use to eat, the way you dispose of the leftovers, and so on. In each of these stages, multiple sensory impressions conveyed by the senses of touch, audition, smell, vision, and taste contribute to the overall experience. This chapter presents a structured design approach in which all sensory modalities are aligned to contribute to the same product expression over multiple stages of consumer interactions. The approach is illustrated through a project aiming to enhance the experience of homemade cooking while using a kitchen appliance.
This systematic overview tries to link scientific knowledge on human perception and appreciation mechanisms to culinary practices. We discuss the roles of the human senses during eating, starting out with basic mechanisms of taste and smell perception, up to principles of aesthetics. These insights are related to how foods are experienced, how ingredients are combined, the use of flavor bases in cuisines, the creation of a full course meal, the choice of a beverage with a dish, and how people learn to appreciate new foods.
Food design is a relatively new discipline that requires designers to become familiar with several areas that are not currently covered in many design curricula, such as agriculture, the food industry, culinary processes and the hospitality industry. To inspire, enrich and facilitate food design processes, we developed and tested a card set reflecting the richness of the food design field. After literature review, we clustered findings into seven main categories: agriculture, industrial processing, distribution & marketing, kitchen management, eater, consumption situation, and policy & legislation. Each category is represented by five topic cards and one overview card. The card set is accompanied by instructions for six exercises. Testing the card set among individual designers and student groups showed that it was considered useful in multiple stages of the design process. In the beginning of the design process, it was used to gain overview and to inspire. Along the process, it enhanced brainstorming, facilitated discussions, and was used to create scenarios and refine ideas. In later stages, the variety of topics was helpful in evaluating whether all important design aspects had been considered.
What makes food design different from other types of industrial product design? Based on over twenty years of professional design practice and food experience research, the authors present a variety of insights – clustered in five overarching themes – that provide an invaluable view on the specifics of the food realm for practicing designers in this field. First of all, foods are based on materials that used to be alive, which makes them highly perishable. Before the widespread introduction of mass transportations systems, foods were usually produced and consumed in the same region. But food technologists continuously try to improve the ways to preserve foods and invest in packaging that protects them in order to increase shelf life and to make them more widely available, while consumers seem to demand more and more freshness. The second challenge is presented by the need to make the food system more sustainable, addressing agricultural production and its impact on biological diversity and the quality of the living environment and also focusing on the amount of waste generated in terms of food or its packaging material. Third, the food people eat is absorbed and transformed into the building blocks of their bodies. Food fulfils a basic human need, and thus, there is a challenge to provide people access to the right amount of safe and nutritious food, in order to keep them healthy. Fourth, food is a source of sensory stimulation that enriches people’s lives. This provides a new sensory spectrum to design for – including flavour and mouthfeel – and it challenges designers to trigger appetite, rather than aesthetics. The fifth challenge addresses preparation practices and the associated cultural differences. Because food stuffs can be prepared in multiple ways, many different products can be created, varying from raw to highly processed, and addressing multiple consumer needs, eating occasions and market segments. These five themes provide interesting challenges for designers that should be tackled in order to provide a healthy and sustainable future for the next generations on this planet.
Affluent societies face several challenges involving the relationships between people and their food, including the rise of welfare diseases and the huge amount of food wasted. These problems are partly due to the operation of the market economy, in which companies develop products that cater to momentary desires of individual consumers. To tackle societal problems, we need to develop different approaches in line with people’s long-term goals and providing benefits to the community, the environment, and society. To achieve enduring changes in behavior, designers can create series of interventions that address all stages people typically go through. In addition, designers, companies and users should be prepared to share the responsibility associated with the potential impact of new product introductions.
The colour of the background on which products are presented may affect their perceived attractiveness. In order to find out on which type of background various fresh food products look most attractive, we presented five different vegetables (tomato, carrot, yellow bell pepper, eggplant, mushroom) on five different backgrounds with neutral grey colours varying in degree of blackness: 5, 30, 50, 65, and 90%. Forty-six participants provided colour matches for the vegetables and evaluated them on 10 attributes.
Overall, the blackness of the backgrounds had little or no effect on the perceived colour of the vegetable. Only for carrots we found a small but significant difference, mainly between the 5% and 90% blackness backgrounds. On the darkest background, the carrot would be perceived as a bit lighter, more saturated, and more yellow rather than red, compared to the lightest background.
Differences in perceived attractiveness on the grey backgrounds varied between 0.3 and 1.0 units on a 9-point scale. Attractiveness and expensiveness ratings for most vegetables were highest on the 90% blackness background. In comparison to our previous study where we presented vegetables on hued backgrounds, differences between mean attractiveness ratings were smaller. Because mean attractiveness ratings in the current study were higher, we expect that grey backgrounds are more likely to present vegetable assortments with a variety of hues in an attractive way than hued backgrounds.
Although experiences are personal and subjective, researchers can investigate them by observing people’s expressions and behavior. This permits to deliberately design these events and see how changes in the design affect people’s experiences. By focusing on experiences rather than products, the effects that products and associated services have in human life and their contribution to the consumer’s well-being are emphasized. This chapter discusses the concept of experience and some of the tools that were developed to create particular experiences.
An overview of student design projects shows how these insights and design tools can be used to inspire innovations in the food domain, with topics varying between attempts to improve nutritional lifestyle, enriching the emotional experiences that food products evoke, and connecting people through the meals they prepare and consume. Using the approaches presented here could contribute to new ways of tackling the imminent challenges the world faces in the food domain.
Even though designers are specifically trained to create and build new products, their contribution to innovation in the food industry is relatively small. The industry seems unfamiliar with the ways in which designers operate and may be unaware of the added value they may provide. Therefore, this article identifies the potential roles that designers could fulfil within large food companies. The development of new consumer products requires knowledge of target consumers, production technology and the business environment. These three types of expertise are often concentrated in different departments. Although highly experienced product experts such as culinary chefs may be able to integrate this knowledge, involving designers may be a more fruitful strategy. First of all, designers tend to approach design challenges holistically, which broadens the scope of the project. As a consequence, designers will provide more innovative solutions, which can guide multiple project aspects simultaneously (production, packaging, marketing). Second, designers shape their own tools, which will engage the others involved. Third, designers are equipped to manage the product development process and can facilitate cooperation between the disciplinary experts. Fourth, designers can play a role in bringing together and integrating the knowledge from the different disciplines. By strengthening these roles, large food companies can deliver innovations that address actual consumer needs, provide a positive contribution to society and consolidate long-term profitability and growth.
For designers, foods represent interesting prototyping materials, which are firmly rooted in daily, cultural practices and can be enjoyed through all the senses. Their regional, seasonal and perishable character challenges designers to connect consumers with agriculture, trading and processing methods.
Designers can play a significant role in providing the world population with food that is produced in a sustainable way, is tasty and healthy and can form the centrepiece in culinary experiences. However, design students will need to acquire more knowledge specific for the food domain if they want to qualify as cooperation partners for other food professionals. In addition, because the food domain is vast and diverse, food design education could focus on various application domains, resulting in design students with different profiles.
In this article, I make a distinction between designing for a person who consumes food at home or is eating out. The first case emphasizes the food itself in the home situation, including food production, packaging, food buying, shelf life, preparation, serving, handling leftovers and waste disposal. In the second case, the consumer’s meal experience depends on the atmosphere in the restaurant, interactions with serving staff, the offerings on the menu and quality of the dish. In addition, several processes take place outside the consumer’s view, such as food preparation, storage, personnel management and business administration.
Based on these topics and comparison with adjoining educational curricula, a list of training topics is derived. For all food designers, this consists of general design capabilities, food science, cooking skills, consumer insights and sustainability issues. In addition, the ‘eating at home’ designer should gather knowledge on agricultural production, food technology and food industry business, whereas the ‘eating out’ designer will need to focus mainly on food product knowledge, culinary technology, equipment engineering, restaurant design, consumer dining behaviour and hospitality business.
The variety of fruits and vegetables in today’s supermarkets is enormous. We investigated how color may lead consumers to anticipate differences in product properties. Forty volunteers rated the expected properties for carrots with different colors presented in pictures, together with their familiarity, purchase intention, and intended preparation method on 7-point scales. We found most positive expectations for the typical and most familiar kinds of orange carrots. Lower saturation of orange was associated with lower attractiveness and freshness, whereas higher orange saturation was evaluated as more artificial. Brown spots on carrots were associated with disease and such carrots were regarded less healthy. Carrots in atypical colors were rated as less familiar, attractive and healthy than orange ones. In comparison with the orange carrots, red carrots were expected to taste sourer and spicier, purple and yellow carrots were rated less nutritious and more artificial, with purple carrots expected to taste more bitter and yellow ones more sour. White and white-green carrots rated lower on sweet, and higher on sour, bitter, and spicy. These carrots were considered less ripe and less nutritious than orange ones. These results indicate that color hue and saturation have substantial impact on consumers’ expectations about sensory and functional properties, including freshness and nutritional value. Some of these expectations may be derived from associations to other vegetables, as reflected by high ratings for spiciness (red pepper) and taste intensity (turnip, radish). However, low attractiveness ratings also suggest that consumers may be reluctant to try unfamiliar variants, at least at first glance. Although atypical colors produce culinary opportunities, commercial success may be limited until consumers integrate them in their everyday habits.
The color of the background on which products are presented may affect their perceived attractiveness. We presented five different vegetables (tomato, carrot, yellow bell pepper, cucumber, eggplant) on four different background colors (orange or blue, either light or dark). Although the backgrounds did not affect the direct color perception of the vegetables, they did affect their perceived attractiveness, with quite different backgrounds proving optimal for the various vegetables. These outcomes suggest that it is difficult to find non-neutral background colors on which a large number of vegetables can be presented in an optimal way.
Methods originally developed for the sensory evaluation of foods are increasingly being applied to other product categories, ranging from personal care products to car interiors and air conditioning units. Furthermore, because an increasing number of food products tend to be available in packages from which they can be consumed directly, the sensory properties of packages have become an integral part of consumers’ food experiences and require thorough investigation. In addition, food consumption in everyday life takes place within a physical, social, and cultural context. This asks for a reconsideration of the role of sensory analysis in the product development process. To seduce consumers in highly saturated markets, products should not only provide good quality and be appealing, but they should offer interesting and engaging experiences. Therefore, research on sensory evaluation needs to be linked to research on product aesthetics, product meaning, and product emotions. Capturing the entire consumer experience requires an integral approach, in which research approaches from various academic fields are combined and integrated. For this approach to succeed in industrial companies, many different departments will need to work together in close cooperation.
Fluid food products are always consumed from a container: a package, a cup, a bowl, and so on. The properties of this container may affect how the food is experienced. In the present study, we develop a method to study the effects of container properties on the experience of drinking beverages. Participants either evaluated empty cups made from different materials, or they evaluated the experience of drinking hot tea or a chilled softdrink from these cups. In all three conditions, the same set of attributes was used. The results suggest that for many attributes the drinking experience followed the experience of the cups. However, some deviations were also evident. Ratings on the cold-warm item increased when hot tea was consumed from some of the cups, probably related to the increase of the outside temperature of the cup. Differences between conditions for other items (e.g., robust-fragile, strong-weak), however, do not seem to be related to physical changes of the cup and may have a semantic or emotional origin.
During the various stages of user–product interactions, different sensory modalities may be important and different emotional responses may be elicited. We investigated how a dehydrated food product was experienced at different stages of product usage: choosing a product on a supermarket shelf, opening a package, cooking and eating the food. At the buying stage, vision was the most important modality, followed by taste. Smell was dominant at the cooking stage, and taste was the most important sensation while eating the food. Analysis of the emotional dynamics showed that ratings for satisfaction and pleasant surprise tended to be lowest during the buying stages. Fascination and boredom ratings tended to decrease gradually over the course of the experiment. Comments mostly reflected responses to sensory qualities, usability aspects, and the nature of the product. At the purchase stage, pre-existing attitudes and stereotypes towards the product group seemed to play a major role in affective reactions, while in the other stages when other modalities were actively involved, participants’ emotional judgements reflected mainly their direct sensory experience.
This study examines the influence of packaging design on taste impressions. Building forth on research addressing transfer effects of symbolic associations from one sense to another, in this study it was studied if, and to what extent, potency-related associations portrayed by shape curvature and color saturation of yoghurt packages transfer to subsequent taste experiences. Furthermore, the influence of participants’ sensitivity to design was taken into account. Data were collected during a field study in the entrance hall of a large supermarket. Results indicate that associations portrayed by shape curvature in particular transfer to taste experiences, but that these effects are most pronounced for participants with a sensitivity to design. In addition, the findings presented indicate that shape curvature and color saturation may impact more general product evaluations and price expectations as well.
Emotions experienced by healthy individuals in response to tasting or eating food were examined in two studies. In the first study, 42 participants reported the frequency with which 22 emotion types were experienced in everyday interactions with food products, and the conditions that elicited these emotions. In the second study, 124 participants reported the extent to which they experienced each emotion type during sample tasting tests for sweet bakery snacks, savoury snacks, and pasta meals. Although all emotions occurred from time to time in response to eating or tasting food, pleasant emotions were reported more often than unpleasant ones. Satisfaction, enjoyment, and desire were experienced most often, and sadness, anger, and jealousy least often. Participants reported a wide variety of eliciting conditions, including statements that referred directly to sensory properties and experienced consequences, and statements that referred to more indirect conditions, such as expectations and associations. Five different sources of food emotions are proposed to represent the various reported eliciting conditions: sensory attributes, experienced consequences, anticipated consequences, personal or cultural meanings, and actions of associated agents.
