A1 - Ritter, Guido T1 - A methodological approach for the on-site quantification of food losses in primary production: Austrian and German case studies using the example of potato harvest JF - Waste Management N2 - In the last decade, in many European Countries more and more measures have been initiated aiming at the prevention of food losses and wastes along the entire value chain. In order to evaluate or monitor such important measures it is crucial to obtain quantitative information on generated food waste amounts, subsequently enabling the quantitative evaluation of the measure’s outcomes and efficiency. Currently there is a paucity of quantitative information, particularly on food losses that are directly generated during harvesting processes. Up to date, no method is available or standardised aiming at the in-situ or on-site quantification of food losses during harvest. Using the example of the potato harvest, this study presents a practical approach for determining potato losses. To test the applicability of the developed method, on-site measurements were conducted directly on the field at five different locations in Austria and Germany. Our method enables the quantification of food losses based on defined areas along the harvested potato rows, where the analyser manually collects potatoes during their harvest. Hereby, two types of potato losses needs to be considered: non-harvested, under-sized potatoes that remain under the earth and the harvested ones, which are rejected on-site because of quality requirements regarding their size, shape, and state of health. Our study shows that between 1 and 9% of field losses (based on yield potential) can be generated during the potato harvest. In future, this method may be the basis for standardised protocols in order to be able to derive cultivar-specific benchmarks and, consequently, to develop measures for preventing food losses. In general, more case studies and evidence-based ground-up measurements on other cultivars and for other regions are needed focusing on the on-site quantification of post-harvest losses.

Diese entstehen tagtäglich über alle Stufen von Lebensmittelwertschöpfungsketten, wobei in Industrieländern insbesondere Privathaushalte negativ hervorstechen. Gleichzeitig weisen Privathaushalte das größte Vermeidungspotenzial auf. Das Ziel der vorliegenden Arbeit ist, einen Beitrag zur Ausschöpfung dieses Potenzials zu leisten, indem Empfehlungen für eine zielgruppenorientierte Kommunikation zur Lebensmittelabfallreduktion hergeleitet werden. Eine quantitative Onlinebefragung (n = 801), die hinsichtlich Alters- und Geschlechterverteilung repräsentativ für die deutsche Bevölkerung ist, wurde im Sommer 2018 durchgeführt. Basierend auf einer systematischen Literaturrecherche wurden Gründe für das Entstehen von Lebensmittelabfällen in Privathaushalten ermittelt und mit Items zu Kommunikationspräferenzen kombiniert abgefragt. Mittels Faktorenanalyse und anschließender hierarchischer Clusteranalyse wurden sechs Konsumentensegmente identifiziert, die sich hinsichtlich ihres Verhaltens, Einstellung und Wissens bezogen auf Lebensmittelabfälle unterscheiden. Die Cluster wurden anhand demografischer Variablen sowie ihrer Kommunikationspräferenzen charakterisiert. Das Resultat der vorliegenden Arbeit sind konkrete Empfehlungen zur zielgruppenorientierten Kommunikation in Bezug auf Lebensmittelabfallreduktionsmaßnahmen. Die statistisch signifikanten Gruppenunterschiede hinsichtlich der Faktoren für das Entstehen von Lebensmittelabfällen unterstreichen den Bedarf der Zielgruppenorientierung, um effektive Maßnahmen zu entwickeln, die schlussendlich einen Beitrag zu einer nachhaltigen Entwicklung leisten. Forschungsbedarf wurde hinsichtlich einer präziseren Charakterisierung der Konsumentensegmente bezüglich ihrer Kommunikationspräferenzen festgestellt.

JF - European Journal of Clinical Nutrition N2 - In a pilot study, we wanted to influence the food selection of employees in a pediatric clinic bistro aiming to increase the sale of “healthy” grain buns (number and proportion of all sold buns). During basic assessment, the mean weekly sale of grain buns was 98 (52.3%) and in the second week of highlighting them on a green napkin under a transparent hood (intervention 1) reached 124 (54.6%). However, just when starting intervention 2 (position in front of the display), the bistro was closed due to the Coronavirus pandemic. Thus, necessary public health measures stopped our interventional public health experiment.

Testing effects of smaller portions and information in a behavioral model. JF - Appetite N2 - To contribute to a better understanding of consumer food leftovers and to facilitate their reduction in out-of-home settings, our study analyzes the effects of two common intervention strategies for reducing leftovers in a holistic behavioral model. Based on a quasi-experimental baseline-intervention design, we analyzed how the display of information posters and the reduction of portion sizes take an effect on personal, social and environmental determinants in a structural equation model. Applying data from online surveys and observations among 880 guests (503 baseline, 377 intervention) during two weeks in a university canteen, the suggested model allows to assign effects from the two interventions on plate leftovers to specific changes in behavioral determinants. Portion size reductions for target dishes are found to relate to lower levels of plate waste based on conscious perception, represented in smaller portion size ratings. Effects from seeing information posters are found to base on changed personal attitudes, subjective norms and perceived behavioral control. However, depending on how an individual reacts to the information (by only making an effort to finish all food or by making an effort and additionally choosing a different dish in the canteen) there are opposite effects on these determinants and consequently also on plate leftovers. Overall, the differentiated results on intervention effects strongly support the benefits of more holistic and in-depth analyses of interventions to reduce plate leftovers and therefore to contribute to more sustainable food consumption in out-of-home settings.

This qualitative study aims to identify basic recommendations of good practice for the food-processing industry in order to prevent and handle food loss and waste. For this purpose, a comprehensive literature review was conducted in the field of food waste prevention and data was collected from thirteen German companies. The findings summarize the recommendations of good practice, which cover the entire supply chain from supplier to consumer and beyond. The analysis showed that the participating companies are already partially aware of operational measures, even if they are applied or mentioned without a systematic approach. Furthermore, the analysis revealed that most activities relate to internal matters, like processing, employees and utilization. However, the responsibility of foodprocessing companies does not end with internal processes to reduce food waste. The results show that some companies are already aware of their responsibility to be involved along the entire supply chain. Finally, the results show that the needs of consumers and suppliers must also be considered in order to reduce food waste, in addition to direct reduction measures. This paper highlights nine important stages and 53 basic recommendations for companies to address food loss and waste in order to improve their practices.

With increasing annual customers, the sector’s impact on the environment is also growing continuously. At the same time, public catering offers a lever to promote sustainable nutrition that has rarely been used so far. Small changes in kitchen practices and food offers can thus be multiplied into a significant positive impact on environmental challenges, such as climate change or loss of biodiversity due to the large number of servings. In contrast to private households, management decisions in public catering can influence the food- related environmental impact of thousands of customers. This article deals with the nationwide level of greenhouse gas (GHG) emissions and resource use in the German public catering segment “business” and its saving potentials by different scenarios of unsupported and supported recipe revision. In this paper, we define "unsupported" as the intuitive optimization of recipes by employees of public catering businesses. In contrast, “supported” approaches had to meet specific target goals, for example of the Deutsche Gesellschaft für Ernährung; engl. German Nutrition Society or the sustainable level. Specifically, we will test how (A) an unsupported recipe revision, (B) a recipe revision based on dietary recommendations and (C) a recipe revision using scientific guidance affect the environmental impact of a dish. As a methodological framework, an online survey of public catering companies was conducted as well as a scenario analysis at menu level and at nationwide level. The results are based on empirical data on the one hand, and on extrapolations on the other. The results show that the nationwide implementation of recipe revision according to scientific guidance—such as concrete target goals for the GHG emissions per serving—can save up to 44% of resource use in the German business catering sector (which corresponds to 3.4 million tons of resources per year) and as much as 40% of GHG emissions (0.6 tons GHG emissions per year). Even in the scenario of unsupported recipe revision, GHG and resource savings of up to 20% can be realized. The results show that public catering can reduce its material and carbon footprint by 20% overnight. Moreover, the findings show indications for the sustainable transformation of public catering. Nevertheless, it must be noted that these are some first steps of the transformation, which will require further changes with even greater impacts and political activities.

After retail, out-of-home catering is the second largest food sales channel in Germany. A variety of means on both the supply and demand side are necessary to stimulate, facilitate and encourage a more sustainable development and minimise GHG emissions in this sector. Nudges are one of these. This paper's focus lies on the demand side. Set in real-world laboratories, we use a standardised empirical approach to compare different nudging interventions belonging to the area of physical environment and consumers’ choice making process. We compare the effects of the same intervention across different settings and the effect of different, sequential nudging interventions in the same setting. Data was collected in eight workplace and school cafeterias in Germany over two project iterations (2016/2017; 2019/2020). A similar intervention design was applied. Comparability was assured by a harmonised menu. The first project iteration revealed that only one nudge (top menu position, +22.5%) led to significant increases in sustainable food choices, while results from the second iteration showed that all nudge interventions (best counter position, +11.6%; top menu position, +6,9%; label plus information, +15.9%) positively influenced consumer choice. Possible explanations such as the stricter compliance to the experimental design in the cafeterias but also societal developments such as the appearance of the Fridays for Future movement are discussed. As results vary between specific locations and settings, our findings suggest that nudges need to be adjusted to situational conditions for achieving highest efficacy.

Derartige Empfehlungen sprechen die Deutsche Gesellschaft für Ernährung (2009), der aid infodienst (2010), die Verbraucherzentrale Nord­ rhein­Westfalen (2010) und andere Institutionen zum Warmhalten von Speisen in der Gemeinschaftsver­pflegung aus.

Insgesamt gestattet die vorhandene Datenlage keine fundierte Beurteilung, ob das Warmhaltesystem eine Schulverpflegung von ausreichender ernährungsphysiologischer Qualität ermöglicht. Die empfohlenen Warmhaltezeiten werden in der Praxis häufig überschritten, was zumindest die sensorische Qualität, aber auch den Nährstofferhalt beeinflussen dürfte.

This study reports the results of the first direct quantification and economic assessment of surplus bread conducted in Italy, involving a panel of 12 bakeries and their branches located in the Lazio region, which compiled a daily diary for 5 months. They are small-scale bakeries which reflect the typical structure of the Italian businesses in the bakery sector, producing fresh bread and selling it directly to consumers. The surplus bread measured during the study consists of 6,694 kg in total, with an average quantity of 4.83 kg/day per bakery. Studying the three main products (common bread, focaccia bread and bread rolls), the average rate of surplus is respectively 5.88 %, 3.99 % and 5.28 % of the production. The corresponding economic loss represents, on average, 5.44 % of the daily turnover. A set of factors seems to exert highest influence on the generation of surplus, as the range of production, location and number of customers. When surplus bread occurs, in 63 % of the cases it is managed on alternative routes to avoid disposal. Even if detected surplus bread does not necessarily become waste, it indeed represents a big loss for bakeries.
