Despite the perfect nutritional value of imperfect “ugly” produce, they are either never harvested or discarded, resulting in escalating farm-to-fork food waste problems in the USA. The purpose of this paper is to investigate US consumers’ perceptions of imperfect “ugly” produce and their willingness to purchase and consume these foods in their households.

Four focus group sessions with at least five voluntary participants per session were conducted. Each session used structured interview questions and the discussions were led by the same moderator. All sessions were recorded, transcribed and analyzed based on published focus group guidelines and recommendations.

The research study has revealed two categories of potential consumers, Influencers and Learners, when it comes to an initial understanding of “ugly” produce consumption. The study also identified nine themes (i.e. food safety, price sensitivity, location of sale, product display, name/label, purpose of use, fun, targeted education and food waste) that consumers hold regarding imperfect “ugly” produce.

Insights from this study provide strategies for sustainable food management that could help stakeholders along all points of the food chain save money, reduce hunger and diminish food waste in our communities.

This study serves to provide preliminary insights in approaching the issue of consumers’ perception of imperfect “ugly” fruits and vegetables from a research perspective. Although a limited number of real consumers from the local community participated, their rich and in-depth qualitative responses defined the scope and the defining questions that need further exploration.

The purpose of this paper is to review, through a systematic literature review, the different perspectives from which imperfect, ugly and suboptimal food products lead to food waste, as well as to ascertain which are the already proposed improvements, and to present further solutions to develop more sustainable food production and consumption.

A systematic literature review was conducted using PRISMA methodology and searching for the following keywords: “imperfect fruit”, “imperfect food”, “ugly fruit” and “ugly food”; the review was carried out within three databases (Emerald, Scopus and Science Direct-Elsevier), starting, since the topic is quite recent, from the first published article on this issue. Only peer-reviewed papers were selected.

Results reveal that, among 188 papers, only 49 fit the aim of the literature review, analysing what strategies can be used to ameliorate consumers' perception of suboptimal food in order to fight food waste. Specifically, four different interventions are suggested: on the supply chain, on personal experience and awareness campaigns, on promoting circular economy, and on marketing and advertising campaigns.

This paper fills a gap in literature since, by the authors' knowledge, this is the first literature review which analyses different strategies on food waste reduction linked to imperfect/suboptimal food, suggesting further steps which may be taken.

This study estimates the land footprint, nutrients and monetary value of persimmon loss in Brazil, and also consolidated the methodological approach for assessing resources related to food loss.

It uses data on the harvested area, production, production loss and production value of persimmon in Brazil from 2014 to 2019. The persimmon loss in Brazil was converted into macro- and micronutrients, land use and monetary value.

The average annual production loss, loss production value and land footprint of persimmon are 35,100 tons, US$12m  and 1,673 hectares, respectively. Persimmon loss represents the average loss per year of 6.6bn grams of carbohydrates, 1.6bn grams of food fibers, 7.2bn milligrams of vitamin C, 41.8bn micrograms of vitamin A, 4.5bn milligrams of calcium and 54.8bn milligrams of potassium. These nutrients have the potential to meet the nutritional daily needs of approximately 135,000, 176,000 people, 270,000, 164,000, 12,000 and 32m, respectively.

Through (1) research and innovation; (2) infrastructure development; (3) training and education; (4) collaboration and networking; and (5) market diversification and value addition, people can increase persimmon shelf life, reduce postharvest losses and create a resilient environment for small persimmon farmers. This approach promotes sustainability in the agri-food system and empowers stakeholders.

This investigation helps to understand the value of food loss, considering the use of natural resources, as well as the loss of nutrients and monetary value.

This study examines the effect of five price perception dimensions (price consciousness, price mavenism, sale proneness, price-quality schema, and prestige sensitivity) on consumer's perceived value (acquisition value, and transaction value), and how perceived value affects consumers' behavioral intentions (purchase intentions, and intentions to recommend). It also examines the moderation role of face consciousness.

A quantitative research methodology using online survey technique is employed to collect cross-cultural data from respondents from China (n = 371) and Egypt (n = 384). Structural equation model (SEM) via SmartPLS v.3.2.9 is conducted to analyze data.

The results show that consumers’ behavioral intentions toward suboptimal fresh produce are positively affected by both dimensions of perceived value. As well as, perceived value is influenced by different price perception dimensions. Moreover, face consciousness partially moderates the relationship between perceived value and behavioral intentions.

To best of the authors’ knowledge, it is the first study to associate price perception dimensions with purchase value dimensions in the context of suboptimal products. It also contributes to utility and purchase value theory by employing the distinct measures of both perceived acquisition value and transaction value, to enable us to obtain a better understanding of the whole picture of perceived value. In addition, it contributes to regulatory focus theory through the inclusion of face consciousness in the purchase value model. Moreover, up to the researchers' knowledge, prior investigation on these issues in Egypt and China as a cross-cultural research does not exist.

The purpose of this paper is to consider the factors that influence food plate waste in a UK university food service setting and the insinuated intention to waste food among staff and students.

The study conducted empirical research using an online questionnaire (n=260) at the university. The data were analysed descriptively and inferentially by IBM SPSS Statistics version 22.

Multiple factors influence the level of food plate waste including gender, different categories of food, plate size, portion size and palatability. Two recommendations to reduce plate food waste in the university food service setting include providing a variation in plate size and pricing strategy by portion rather than a whole meal, and communicating with staff and students in the food service setting.

The research contributes, along with previous studies, by focussing here on participants’ food waste intention in food service settings and evidencing the factors of influence.

The research contributes to understanding on participants’ food waste intention in food service settings.

This chapter analyzes consumers’ social representations associated with food waste and their influence on their behavior. A series of semi-structured face-to-face interviews was conducted with 22 individuals, who were heterogeneous in terms of age (21–64, mean age 42), gender, SPC, geographical location, and family situation. The second set of data collection involved administering a questionnaire to 76 consumers aged between 19 and 37 in France. They were asked to give four synonyms on the basis of key words (waste and food waste) and to classify 20 terms presented to them from the most to the least significant as regards the theme of food waste. The results show that food waste depends on the individual’s emotional and gustatory, health-related, economic and/or symbolic, and moral representations. The central core of social representations is around the nature/culture of food. Managerial action should focus on the revalorization of foods and to restoring meaning to the eating/food relationship, orienting consumers toward the hedonic, ethical and symbolic values of food products, and experiences.

This paper seeks to understand children’s responses to food waste in school by exploring children’s views on food waste and empowering them to discuss and develop their own solutions.

Using creative problem-solving approach and photovoice technique, the authors conducted focus group discussions with 28 primary school children in the UK.

Children have a clear understanding of the consequences of food waste for individuals, society and the environment. They displayed negative emotions concerning food waste and responded positively to the possibility of food recycling. Their solutions to reduce food waste will require multiple stakeholder engagement, including self-regulation, peer-monitoring, teacher supervision and family support. However, rather than relying on intervention schemes that require significant adult involvement, children placed a heavy emphasis on self-regulation, playing an active role in addressing food waste in school.

This research extends previous understanding, by showing children as agentic consumers who can shape food waste solutions in school. These findings are of use to primary teachers and local education authorities, to aid children in developing their own solutions to reduce food waste in their own schools.

The purpose of this study was constructed a behavioral observation scale for avoiding food waste from the point of view of Chinese cuisine, used as an evaluation tool to examine food waste in the process of food preparation for hospitality students in Taiwan.

The status of food handling in the preparation process was understood through a literature review and interviews. In addition, the indicators that may cause food waste behaviors were established, and the observation and self-evaluation scales of food waste behaviors in the preparation process were developed.

Avoiding water waste, removing excessive edible parts, avoiding waste on seasonings, avoiding cooking for too long and avoiding water stains in the cleaning process were considered by both the observers and the students as items for improvement in the cooking process. The results of this study will help in understanding the intervention in the teaching practice of avoiding students’ food waste behaviors.

This study can only be based on the test results of the current observation behaviors. Meanwhile, many factors need to be taken into consideration, such as the differences in the amount of knowledge students have about food waste, the differences in preparation techniques, and other different factors, which may lead to differences in the research results.

The behavioral observation and self-evaluation behavior scales of “exploring food waste behaviors in the preparation process” were developed and implemented for the current status. The differences between the results of the observation scale and the self-evaluation scale were compared. In addition, the behaviors that may cause students’ food waste were pointed out. Then, the direction of the teaching content was formulated, and the curriculum plan integrating the content of avoiding food waste into teaching was evaluated. Furthermore, the scales can be applied to kitchen staff handling food materials to understand the current situation of their food handling, which can be used as a driving tool for restaurants to reduce food waste.

The purpose of this paper is to focus on food consumption as part of the wicked problem of obesity. Specifically, the authors seek to explore the complex interplay between stakeholders such as food producers, marketers, health and medical practitioners and policymakers and their influence on the ways in which individuals consume food and also chart a course forward using a systems approach, social marketing techniques and social enterprise to develop solutions to effect change.

This is a conceptual paper that proposes the food system compass to understand the complex interplay between stakeholders.

This new tool will provide social marketers with an improved understanding of the complexity of interactions between stakeholders and outcomes and integrating the necessity for coordination within and across micro, meso, exo and macro levels of the system as well as across sectors, institutions and stakeholders.

This is a conceptual paper and proposes the food system compass which offers a foundation for future research to expand upon.

This paper seeks to advance the theoretical base of social marketing by providing new insights into the trans-disciplinary and dynamic circumstances surrounding food consumption and obesity and highlights leverage points where joint actions can be facilitated with actors across and between micro, meso, exo and macro levels.

This paper aims to examine if the response device (smartphone vs computer) used by participants in online data collections affects their responses. The screens of smartphones and computers differ in size, and the main hypothesis here is that screen size is likely to be influential when stimuli with aesthetic qualities are shown on the screen.

Two experiments, in which pictures of food items were used as stimuli, were conducted. In each experiment, the screen size of the participants’ devices used for the responses was a measured factor.

Participants with large screen devices responded with a higher level of (a) positive emotions and (b) attractiveness perceptions than participants with small screen devices.

The results highlight that the participant’s device can be a confounding factor in research projects comprising online data collections. Screen size thereby represents an additional factor calling for caution in the “exodus to cyberspace” that characterizes many contemporary researchers’ data collection activities.

When data are collected online, participants’ can use devices that differ in terms of screen size (e.g. smartphones, tablets and computers), but the impact of this factor on consumer behavior-related response variables has hitherto not been examined in existing research.
