Report on consumers’ general interest in alternative protein food products in Mediterranean countries (2025)
DOI: 10.13140/RG.2.2.20616.89608
The ProxIMed project aims to introduce proteins from sustainable sources into the Mediterranean food and feed systems to promote and establish the use of alternative proteins. To ensure that consumers accept the developed products and meet their expectations, this study analysed Mediterranean consum- ers’ general interest in alternative protein food products using a focus group study conducted in Türkiye, Tunisia, and Portugal. In the focus group study, two focused group workshops each were conducted for various food products, including pickles infused with proteins from tomato pomace and leaves, insect proteins, sesame cake and date by-products, and mycoproteins. The focus group workshops were audio recorded and subsequently analysed using qualitative data analysis methods. The results of this study show that the general interest and awareness of alternative proteins varies be- tween Mediterranean consumers and countries and also depends on the specific food products. Various factors influence the interest of Mediterranean consumers in new alternative protein food products, in- cluding cultural aspects or aspects related to the product. Alternative protein sources derived from fa- miliar or traditional agricultural products such as dates can enhance the openness to innovative alterna- tive protein products. Also, integrating the alternative proteins into popular staple food, can be a prom- ising strategy to introduce alternative proteins into Mediterranean diets. Interest in more uncommon alternative protein sources like mycoproteins and insect-proteins differed. In the case of mycoproteins, unfamiliarity with this protein source and lack of information about such products was detected. Insect- based products evoke a range of consumers’ reactions, from openness to disgust, and the appearance and presentation of the food products seem to have an essential impact on Mediterranean consumers’ acceptance. Critical factors for developing marketing strategies for alternative protein food products include, for example, a carefully designed pricing strategy, considering the specific economic situation of the target market, or a mix of different communication activities. Overall, the study identified various starting points to increase the interest in alternative protein food products in Mediterranean countries and thus enhance the success of integrating alternative proteins in Mediterranean diets.

Im Projekt wurde eine Studie an 39 Senioren in 2 Pflegeeinrichtungen durchgeführt. Ziel war es, Anreicherungstechniken für eine komplette Nährstoffanreicherung zu entwickeln, in verschiedenen Pflegeeinrichtungen durchzuführen, sowie die Entwicklung von neuen kostengünstigen Proteinformulierungen. Die Pflegekräfte können damit, dem Probanden die gewünschte Menge Proteinsahne geben und stellen so die Nährstoffaufnahme sicher. Zudem konnten bei der Studie Mahlzeiten für Bewohner mit Kau- und Schluckbeschwerden verbessert werden. Diese Personen bekamen vor der klinischen Studie täglich püriertes Essen. Um den optischen Eindruck zu verbessern, wurde dies in der Studie mit einem Texturierungsmittel versetzt und mit Silikonformen wieder in die originale 3D Form gebracht. Vor dem Servieren wurden die Lebensmittel aus den Formen gelöst, auf den Teller gegeben und erwärmt. Das Pflegepersonal bestätigt, dass die Bewohner ihr Essen wieder besser erkennen konnten und eine deutlich höhere Begeisterung für die Mahlzeiten haben. Ziel des 2. Projektteils war es, die Wirksamkeit personalisierter Preispromotionen für gesunde Lebensmittel in Supermärkte zu testen, um Konsumenten zu einer gesünderen Lebensmittelwahl zu bewegen. Hierzu wurden auf Basis von Verbraucherpaneldaten verhaltensbezogene Verbrauchersegmentierungen für verschiedene Warengruppen durchgeführt. Zur Bestimmung der Einflüsse von maßgeschneiderten Aktionen auf den Kauf von fettarmen Produkten wurden ein Modell und eine simulationsbasierte Methode entwickelt. Der Ansatz basiert auf einem gemeinsamen Modell aus Kaufereignis, Wahlentscheidung und Kaufmenge und wurde für verschiedene Ebenen umgesetzt. Zudem wurden die Absatzahlen verschiedener Filialen eines Lebensmittelhändlers für definierte Warengruppen vor und nach einer Preisreduktion untersucht. Die Ergebnisse einer Online-Studie zeigen, dass bei der Entscheidung für Joghurt die Inhaltsstoffe die wichtigsten Entscheidungskriterien für Probanden darstellen.

This study examines the socio-economic trade-offs required to foster public acceptance of green hydrogen production in Germany, focusing on regional differences in compensation needs for affected households near green hydrogen plants, based on a survey conducted in 2022/23. Using a choice-based conjoint experiment and Willingness-to-Accept (WTA) analysis, the preferences of households in three focus regions were analysed, emphasising their resistance to importing renewable electricity over locally sourced alternatives. Results indicate that urban areas require significantly higher compensation payments due to dense populations and limited production capacity, while industrial regions have lower compensation requirements due to fewer affected households and large-scale production. The study also evaluates the feasibility of financing compensation payments through cost savings by importing renewable electricity from Spain. Although economically viable under certain policy scenarios, such savings are insufficient to offset compensation costs in densely populated areas. The findings highlight the inevitability of imports due to Germany's limited renewable energy capacity but underscore the necessity for region-specific compensation schemes to address different regional preferences. Policymakers are requested to define transparent compensation mechanisms, prioritise localised renewable energy production where feasible, and establish international partnerships for cost-effective electricity imports. These strategies will ensure a balanced approach to advancing Germany's green hydrogen economy while maintaining public support.

Thanks to their environmentally friendly properties, bio-based insulation materials can positively contribute to reducing CO2 emissions. Despite this, private homeowners often opt for conventional alternatives, which is reflected in the low market share of bio-based insulation materials, e.g., in Germany. To analyze the factors influencing the installation of bio-based insulation materials by private homeowners, this paper uses an expanded version of the Theory of Planned Behavior (TPB). A total of 1194 private homeowners in Germany who have already realized or planned insulation activities were surveyed via an online panel. The findings indicate that Perceived Environmental Knowledge and Environmental Concern are significant predictors for Subjective Norm, Attitude, and Perceived Behavioral Control, which in turn have a significant positive influence on Intention. In addition, the Perceived Effectiveness of Support Programs is identified as having a significant but negative influence on Intention. The behavior of installing bio-based insulation materials is positively influenced by both Intention and Perceived Behavioral Control. The results support policymakers and marketers in developing marketing and education campaigns and feed into approaches for promotion measures for bio-based insulation materials.

Forecasting sales and identifying purchase-driving attributes of perishable products with explainable artificial intelligence based on the example of yogurt (2025) British Food Journal , S. 1-21.
DOI: 10.1108/BFJ-03-2025-0291
Understanding the product attributes that drive consumer purchases is crucial for retailers and marketers to remain competitive. However, extrinsic and intrinsic attributes are often analysed in isolation, overlooking their complex interplay in real-life sales scenarios. This study aims to investigate how intrinsic and extrinsic yogurt attributes influence sales forecasts and consumer purchasing decisions.This study addresses this limitation by evaluating the positive or negative impact of yogurt attributes on sales forecasts, representing properties that support high sales figures of these attributes. Forecasts were generated using the machine learning (ML) method eXtreme Gradient Boosting (XGB), a decision tree-based ensemble learner. This model was trained on four years of data that included diverse yogurt attributes available to consumers at the point of sale, such as price and nutrient facts. A subsequent SHapley Additive exPlanations analysis provided a detailed overview of extrinsic and intrinsic attributes supporting high sales figures. The corresponding code is publicly available at https://github.com/grimmlab/Forecasting-Perishables-with-XAI.XGB achieved strong forecasting performance with an R2 score of 0.89. Calorie content emerged as the most important intrinsic attribute, while price was identified as the most influential extrinsic feature.These findings offer valuable insights for marketers, retailers, and product developers, highlighting the complex interplay of product attributes in shaping yogurt purchase behaviour and showcasing the practical application of ML and explainable artificial intelligence in consumer analytics.This study offers practical insights into the interpretation of ML forecasting models in retail environments. Furthermore, it offers a holistic approach to extrinsic and intrinsic attributes affecting perishable food product purchases.
Worldwide, billions of ultra-thin plastic bags for fruits and vegetables are used annually for convenience, contributing substantially to environmental pollution. To address this issue and better understand the drivers and barriers to adopting greener or packaging-free shopping behavior, this study examines real-life purchase decisions at the point of sale. A field experiment was conducted in four German supermarkets, combining structured observations of more than 3,000 fruit and vegetable purchases, followed by 413 quantitative interviews. Results show that more than half of consumers already avoid single-use plastic bags for bulk produce. Behavioral intentions, perceived knowledge, involvement, and emotional response contribute significantly to different packaging choices, whereas subjective norms, perceived behavioral control, and environmental concerns have only a limited impact. This study advances theoretical research with empirical insights from real-world consumer behavior and provides practical guidance for stakeholders seeking to foster sustainable consumer behavior.

The intensive use of plastics, especially single-use packaging, in the food industry significantly impacts the environment. Reducing conventional food packaging is, therefore, a global challenge. While consumers drive market acceptance, it is essential to better understand their decision-making processes. Despite numerous studies, gaps remain in comprehending how consumers form preferences and behavioral intentions regarding sustainable food packaging, particularly concerning their affective and cognitive appraisals. This field study investigated 492 participants directly at the point of sale in four supermarkets across Germany, ensuring that participants were actively engaged in food-purchasing decisions, with their attention already focused on grocery shopping. The study reveals the multifarious factors influencing consumers' preferences and behavioral intentions toward environmentally friendly food packaging alternatives. By applying a structural equation model, it becomes evident that consumer choices are predominantly driven by preferences and emotions rather than knowledge and rational considerations. Environmental concerns also strongly influence consumer awareness and preferences; however, other factors have a greater impact on their behavioral intentions. Our study's distinct approach provides valuable insights into consumer decision-making and highlights that emotionally engaging consumers can strengthen their intrinsic motivation for responsible plastic packaging choices.
Transitioning from fossil fuels to renewable energies is imperative for Germany to reduce CO2 emissions and achieve greenhouse gas neutrality by 2045. Green hydrogen holds great potential to contribute to this energy transition by enabling the storage of surplus renewable energy. However, Germany's green hydrogen production industry is still in its infancy, with only a few green hydrogen plants existing. Studies examining the public's acceptance of green hydrogen production are scarce in this context. Still, high societal acceptance can contribute to the future expansion of green hydrogen production in Germany in terms of speed and volume. Therefore, our study aims to identify significant factors influencing the German population's acceptance of green hydrogen production within various acceptance groups with differing preferences for future green hydrogen production systems. We conducted an online survey (n = 1203) in Germany in 2022/2023, incorporating a choice experiment. Through subsequent latent class analysis, four acceptance groups with distinct preferences regarding local green hydrogen production were identified: Unconvinced citizens, Security-conscious citizens, Regional electricity consumers and Financial beneficiaries. A discriminant analysis identified 9 out of 11 factors as significant for distinguishing between these acceptance groups regarding their preferences for local green hydrogen production: trust in plant safety, trust in project managers, risk/benefit perception, environmental self-identity, negative attitude towards renewable energies, positive attitude towards renewable energies, emotions, age, and gender. However, no significant effects were observed for experience with green hydrogen and distance to the place of residence. Based on our results, it is recommended that required renewable energy for green hydrogen production should be produced as close to the green hydrogen plants as possible. It must be ensured and communicated to the public that the (planned) green hydrogen plants meet high safety standards and pose a very low risk of fire or explosion. The neighbouring population should also benefit through annual heating cost savings and financial participation. Implementing these measures can increase acceptance of local green hydrogen production, facilitating the transition towards a more sustainable energy future in Germany and beyond.
Considering global plastic waste pollution, current production and consumption patterns must be changed. Various measures address this challenge, which can be divided into efficiency, consistency, and sufficiency. Sufficiency has become more critical as research on sustainable consumption and packaging-related behavior has shown that efficiency and consistency strategies alonecannot solve environmental challenges. A deeper understanding of consumers’ packaging-related behavior is necessary to promote sufficiency-oriented consumption patterns and support consumersin everyday implementation. This study aims to investigate consumers’ packaging-saving practices in the fast-moving consumer goods (FMCG) sector and to explore to what extent the practices differ in their actual feasibility in everyday life. For this purpose, we conducted an online survey in Germany with open-ended questions (n = 299). We evaluated the open-ended questions using qualitative content analysis. Overall, the results show that reducing plastic packaging plays a significant role in the participants’ everyday lives. However, the extent to which plastic packaging is avoided or reduced varies by consumption sector. This study extends research on plastic packaging avoidance and reduction to non-food consumption sectors. It also provides essential impulses for actors from science, politics, and industry regarding how consumers can be more strongly supported in their packaging-related behavior in the future, through targeted measures.
Predictive models are increasingly crucial in navigating heterogeneous markets. This study develops a predictive model approach to forecast consumer cluster membership in the green fast-moving consumer goods sector, focusing on bio-based products like adhesives and plasters. Through two online surveys in Germany, we identified key factors acting as drivers and barriers, demonstrating their effectiveness in distinguishing similar consumer segments across both product categories. Utilizing multinomial logistic regression, we crafted a prediction model that accurately forecasts cluster membership, providing novel insights into consumer behavior towards non-food bio-based products. This facilitates the development of targeted business and marketing strategies, optimizing resource allocation in market research activities. Our findings offer significant contributions to understanding the dynamics influencing consumer choices in the bio-based product market.
To achieve greenhouse gas neutrality by 2045, Germany must reduce its CO2 emissions, and German policies aim to ramp up domestic green hydrogen production. So far, green hydrogen production in Germany is still in its early stages, with few existing green hydrogen plants. Amongst other factors, public acceptance is crucial for successfully expanding green hydrogen production. However, few studies have investigated the acceptance of green hydrogen plants or production. Thus, this study aims to identify key factors influencing the acceptance of green hydrogen plants in Germany, focusing on the influence of participation in green hydrogen projects. A nationwide online survey (n = 1203) collected data from 1203 respondents living in regions with existing or planned green hydrogen plants in Germany. A multiple linear regression model identified eight key factors that influence the acceptance, including trust in plant safety, trust in project managers, information, risk/benefit perception, experience with green hydrogen, and gender, all having a significant positive impact on the acceptance of green hydrogen plants in Germany. Conversely, participation in the form of consultation and environmental self-identity negatively influence the acceptance of green hydrogen plants in Germany. The results support political decision-makers and stakeholders in realising future green hydrogen projects with high societal acceptance and address potential concerns, thus facilitating the transition towards a more sustainable energy future in Germany and elsewhere.

Es scheint ein allgemeines Bewusstsein dafür zu geben, dass es sowohl ökologisch als auch sozial notwendig und erwünscht ist, den Einsatz von Kunststoffen auf Basis fossiler und damit endlicher Ressourcen zu reduzieren. Zugleich sind sie jedoch aus dem Konsum- und Lebensalltag nicht mehr wegzudenken: Ein Leben ohne Kunststoffe ist für etwa ein Viertel der deutschen Bevölkerung unvorstellbar – auch wenn zugleich der Wille bekundet wird, auf Kunststoffe aktiv zu verzichten (29 %) bzw. man dies eigentlich tun möchte (48 %) (Blesin et al. 2017).
