Communicating upcycled foods: Frugality framing supports acceptance of sustainable product innovations

A systematic literature review and future research agenda to study consumer acceptance of novel foods and beverages

In response to the rising global demand for healthier and more sustainable food resources, novel and unconventional food and beverages are being developed and incorporated into our diets. However, existing literature provides a limited understanding of consumers' acceptance of these innovations. This study undertakes a systematic literature review to examine the dynamics between consumers and novel foods and beverages. The objectives are to uncover the factors that influence consumer choices of these products, identify future research needs, and contribute to the development of effective marketing strategies for novel food and beverage adoption. This systematic review analyses 99 research papers, selected from an initial pool of 4,280, sourced from Scopus and Web of Science databases. The papers were published between 2011 and 2023 in journals listed by Australian Business Deans Council and classified as Q1 in the SJR journal ranking. The articles have been reviewed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) protocol and TCCM (Theory, Context, Characteristics and Methodology) framework. The findings highlight a reliance on data-driven methods and suggest that integrating relevant theories could enhance future research outcomes. Most studies focused on the acceptance of technology-based innovations in developed countries, indicating a need to explore novel foods and beverages in developing regions. Consumer-related factors, especially psychological aspects, were the primary focus, suggesting opportunities to investigate additional variables, such as product-related and situational factors, that influence acceptance. Finally, the predominance of quantitative research indicates a potential benefit in incorporating qualitative and multi-method approaches to gain deeper insights into consumer attitudes and motivations.

Unboxing the dilemma associated with online shopping and purchase behavior for remanufactured products: A smart strategy for waste management

Despite an unprecedented shift in favor of sustainable consumer purchase patterns globally, the overall adoption of refurbished products is still scarce. Earlier empirical investigations have tested aspects affecting consumer purchase intentions concerning remanufactured products, yet they largely ignored risks hindering consumers from opting for them. In order to fill the given theoretical gap, the study tests both inhibiting and igniting factors affecting consumer's remanufacturing products purchase behavior through the use of Stimulus Organism Response (SOR) theory. SOR assists in better understanding consumers' digital purchase behavior toward remanufactured products. Moreover, the study extends the knowledge by examining the impact of Perceived Environmental Benefits, Seller's Reputation, Price Sensitivity, and Social Influence on Consumer's Purchase behavior for remanufactured products. It also investigates the mediating role of the Perceived Risk of Remanufactured Products, followed by the moderating role of Consumers Trust. A useable sample data of 361 was collected through structured questionnaires and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results indicated the inverse relationship between increased price sensitivity and purchase behavior concerning remanufactured products, and all other stated variables reflected a significant association with consumer purchase behavior. Likewise, both mediating and moderating roles were found to be significant. Along with theoretical contributions, the study contains numerous practical directions for policymakers, industry stakeholders, and researchers to increase consumers' purchase behavior toward remanufactured products.

Impact of circular economy information on sensory acceptability, purchase intention and perceived value of upcycled foods by young consumers

The acceptability of upcycled foods is influenced by individual, context and product-related factors. This study aimed at investigating the impact of circular economy (CE) information on consumers' sensory acceptability, purchase intention and perceived value of upcycled foods, taking into account eating behaviours and personality traits that could be related to the consumers' sustainable consumption habits. To this aim, a group of young subjects (n = 80, 18-35 years old) participated in a two-step study. Firstly, an online questionnaire was administered to participants to gather information about their individual characteristics. Then, participants were divided into two groups, one receiving CE information (CE+) and one not receiving it (CE-), and they were asked to indicate the sensory acceptability, purchase intention and the perceived value of three upcycled foods, such as biscuits with grape pomace flour, beer brewed with leftover bread and a dairy product made from recovered crushed cheese. Questionnaire results showed that high individual responsibility, interest in healthy foods and high awareness of the social impact of their behaviours could be linked to a positive purchase intention for upcycled foods, as opposed to individual disgust sensitivity. No significant effect of CE information (p > 0.05) on sensory acceptability and purchase intention of all three upcycled foods was observed. Moreover, application of Principal Component Analysis (PCA) to the sensory data resulted in satisfactory classification of upcycled foods in terms of perceived values, explaining 86.83 % of data variability: the first principal component discriminated samples according to product category whereas the second principal component was able to clearly separate products according to CE information. Findings from this study provided valuable insights into the key individual characteristics that impact sustainable consumption habits, also highlighting the role of communication strategies in shaping consumer perceptions of upcycled foods so as to encourage a more sustainable consumption behaviour.

Upcycling in the context of biotechnology-based solutions for food quality, loss, and consumer perception

Wasted food is the single biggest contributor to greenhouse gases. Globally, attempts are being made to both reduce surplus food and divert it into food-to-food operations. This opinion piece covers upcycling and biotechnology-mediated solutions on a technology continuum as a part of the bigger whole to solve this problem. Upcycling is an approach to divert foods that would otherwise be wasted into higher uses that would also have tangible benefits to the environment and society. Likewise, biotechnology can help farmers produce crops with longer shelf life and that satisfy cosmetic standards. Uncertainty, either in the form of food safety, technology, or neophobia in the case of upcycled foods or genes (cisgenic or transgenic) in the case of biotechnology, is a hurdle. Communication and consumer perception should be researched. Both upcycling and biotechnology can provide practical solutions, but their acceptance depends on communication strategies and consumer perception.

Towards halving food waste: A comparative study using orange juice by-product in dairy desserts

By-products upcycling to produce ingredients has increased in the last years. However, the perception of foods with these ingredients must be studied to find the proper way to inform the consumer. The aim of this work was to study the purchase intention and healthiness and environmental friendliness perceptions of a flan dessert, enriched with orange juice by-product fibre. The effect of different product categories (ready-to-eat, powdered form, home-made type), fibre origin claim, and the addition of a sustainability logo in the packaging were studied through an online survey carried out in Spain (n = 342) and Uruguay (n = 307). Data were analyzed by PLS and cluster analysis. Both Spanish and Uruguayan participants considered the product category the most important attribute in purchase intention and in healthiness and environmental friendliness perception, being the home-made product preferred by both. Logo presence was more important for purchase intention and perceived environmental friendliness, while information about fibre origin was more important for healthiness perception. The home-made product with a logo and the claim about fibre origin was the one that had the highest perception of being healthy and environmentally friendly in both populations. Logo presence affected positively purchase intention for both groups, but the relative importance was higher in the case of Spanish consumers. The allegation "source of fibre" also increased healthiness and environmental friendliness perceptions, although not the purchase intention in Spain. Cluster analysis identified different groups of consumers on each country, who gave different relative importance to each attribute in purchase intention.

The Need for Consumer-Focused Household Food Waste Reduction Policies Using Dietary Patterns and Socioeconomic Status as Predictors: A Study on Wheat Bread Waste in Shiraz, Iran

Current household food waste (HFW) reduction plans usually focus on raising consumer awareness, which is essential but insufficient because HFW is predominantly attributed to unconscious behavioral factors that vary across consumer groups. Therefore, identifying such factors is crucial for predicting HFW levels and establishing effective plans. This study explored the role of dietary patterns (DP) and socioeconomic status (SES) as predictors of HBW using linear and non-linear regression models. Questionnaire interviews were performed in 419 households in Shiraz during 2019. A multilayer sampling procedure including stratification, clustering, and systematic sampling was used. Three main DPs, i.e., unhealthy, Mediterranean, and traditional, were identified using a food frequency questionnaire. Results indicated that a one-unit rise in the household’s unhealthy DP score was associated with an average increase in HBW of 0.40%. Similarly, a one-unit increase in the unhealthy DP score and the SES score increased the relative likelihood of bread waste occurrence by 25.6% and 14.5%, respectively. The comparison of findings revealed inconsistencies in HFW data, and therefore the necessity of studying HFW links to factors such as diet and SES. Further investigations that explore HFW associations with household characteristics and behavioral factors will help establish contextual and effective consumer-focused plans.

European Consumers Attitudes toward Ethnic Foods: Case of Date Fruits

This study focuses on the perception of ethnic foods by European consumers. The aim of this work is to enrich the literature on the analysis of consumer perception of ethnic foods by focusing on the socio-demographic characteristics of consumers, the possible role played by product attributes, psychographic characteristics, and willingness to pay for these products, specifically date fruits. We surveyed a representative sample of 1123 Italian and French consumers. Using an ordered logit model, we found that, as for any other product, geographical indication, region of production, organic character, and fair trade are attributes that individuals consider in their purchase decisions for ethnic foods. Similarly, country of origin is a source of quality for ethnic foods such as dates. The results reveal that women, more educated individuals, and Generation Z (younger individuals) have a higher willingness to pay for organic, fair trade, and GI-labeled ethnic foods. Finally, this willingness to pay is driven more by product knowledge than by cognitive closeness to the ethnic food.
