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 report deals with the regional supply situation of biogenic products in three application areas (natural cosmetics, outdoor equipment, building materials) in Bavaria and the views and estimations of consumers on this situation. Based on the outcome of the analysis, recomendations for policy and other actors are derived.

Bio-based products represent a promising alternative to fossil-based products and contribute to reduce negative environmental consequences caused by the latter. As consumer behavior is crucial for market penetration of bio-based products, this review analyses the current state of the art in consumer research on bio-based products and aims to identify research gaps and future research needs. This review is based on a systematic synthesis of 59 scientific journal articles and one book chapter on consumer studies related to bio-based products. Peer-reviewed studies in English language, with a research focus on consumer issues related to bio-based products of plant origin, that aim to replace fossil resources, have been included in the review. Most reviewed studies investigated bio-based plastics and composites, used a quantitative research approach, have been based on established consumer theories and used non-probability sampling techniques. While consumer preferences and attitudes, conviction as well as knowledge and perception related to bio-based products were focus of many reviewed studies, consumer awareness, liking and purchasing of bio-based products have been studied rarely or not at all. The results show that many consumers are not aware of the existence of bio-based products, related knowledge is low, and labels and brands are often unknown. Additionally, some consumers have wrong assumptions about the environmental impact of bio-based materials. Consumer preferences vary between product groups, but often factors like price or functionality are more important than bio-based materials. High purchase intentions and an increased willingness to pay are found e.g. for bio-based packaging products, disposable products and plant containers (in particular for female and environmentally-concerned consumers). The review identifies important research gaps and conclusions for future research needs such as e.g., to realize more studies in countries of the global south, analyze actual purchase behavior and the regional supply situation related to bio-based products.

Investigating unconscious human behaviours is a complex issue, given that people have hardly access to their unconscious. Food-related behaviour is one of these behaviours in which the unconscious plays a central role. Therefore, the connection of the unconscious and food-related behaviour is difficult to comprehend. Hence, our exploratory study deals with the relationship between implicit motives as an important part of the unconscious and their relationship with food-related behaviour. For this purpose, we used the Operant Multi-Motive Test (OMT), which offers information about implicit motives of individuals. Based on 37 qualitative problem-centred interviews conducted in Bavaria, Germany, we identified seven eating action types that we combined with the results derived from the OMT. These deliver profound insights into how people eat due to their identity. The approach of this study is explorative and provides a first insight into a possible relationship between implicit motives and food-related behaviour that are presented descriptively. Our initial results show that a relationship between implicit motives and food-related behaviour can be assumed, although it cannot be directly deduced from the sole analysis of food-related behaviour. However, nutrition consultancies, food companies, policy makers and advisors may be interested in these insights related to understanding the impact of the unconscious on food-related behaviour.

Public acceptance of agricultural technologies is an important determinant of their success. In the case of autonomous crop robots, recent research from Germany suggests that societal acceptance of the technology plays an important role for farmer acceptance of crop robots. Yet little research has been conducted so far into how the public perceives autonomous agricultural technologies like crop robots. Investigating the public’s opinion on crop robots will provide answers to one of farmers’ questions in the decision to invest in crop robots. Through consumer segmentation and hypotheses-based characterization, specific consumer groups with differing attitudes towards crop robots are identified. Two discrete choice experiments on digital and autonomous methods of weed management (n = 675) and tractor size and degree of autonomy (n = 645), conducted as part of a larger representative consumer survey in Germany (n = 2,012), are submitted to a Hierarchical Bayes estimation and subsequent latent class analysis. The identified consumer segments are characterized in a hypotheses-based approach with hypotheses centering on consumer attitudes measured as 5-point Likert-type items and as spontaneous image associations. Both subsamples can be segmented into three groups, which are comparable between the experiments in their socio-economic composition. Results suggest that the German public is largely positively inclined towards autonomous agricultural technologies. The method of weed control is considered more important than the vehicle type (i.e., conventional tractor or crop robot) and vehicle size is considered more important than degree of autonomy. Only the respective smallest consumer segments in the two experiments indicate indifference or a more conservative perspective. Participants’ attitude towards environmental preservation appears to have a positive influence on their evaluation of autonomous agricultural technologies. To the authors’ best knowledge, this is the first investigation into the public opinion of crop robots, based on a large sample representative of the German population in four socio-demographic variables. It indicates that the German population is most interested in the reduction of agrochemicals in plant production and will also accept autonomous agricultural technologies to achieve this goal. Policymakers should make use of these insights when communicating about novel technologies in agriculture and extension agents should relay this information to farmers, particularly those already interested in investing in crop robots.
