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.}, language = {en} } @article{StrotmannGoebelFriedrichetal.2017, author = {Strotmann, Christina and G{\"o}bel, Christine and Friedrich, Silke and Kreyenschmidt, Judith and Teitscheid, Petra and Ritter, Guido}, title = {A Participatory Approach to Minimizing Food Waste in the Food Industry—A Manual for Managers}, series = {Sustainability}, volume = {2017}, journal = {Sustainability}, number = {9(1)}, doi = {https://doi.org/10.3390/su9010066}, pages = {66}, year = {2017}, language = {en} } @article{StrotmannGoebelFriedrichetal.2017, author = {Strotmann, Christina and G{\"o}bel, Christine and Friedrich, Silke and Kreyenschmidt, Judith and Ritter, Guido and Teitscheid, Petra}, title = {A Participatory Approach to Minimizing Food Waste in the Food Industry—A Manual for Managers}, series = {Sustainability 9(1):66}, journal = {Sustainability 9(1):66}, issn = {2071-1050}, doi = {10.3390/su9010066}, year = {2017}, language = {en} } @incollection{SpeckRohnTeitscheidetal.2016, author = {Speck, Melanie and Rohn, Holger and Teitscheid, Petra and Langen, Nina}, title = {Assessing sustainable limits for meals - first results from the project NAH_Gast: Developing, Testing and Dissemination of concepts for sustainable production and consumption in the food service sector}, series = {Conference: Global Cleaner Production \& Sustainable Consumption Conference Accelerating the Transition to Equitable Post Fossil-Carbon Societies, At Sitges, Spain}, booktitle = {Conference: Global Cleaner Production \& Sustainable Consumption Conference Accelerating the Transition to Equitable Post Fossil-Carbon Societies, At Sitges, Spain}, year = {2016}, language = {en} } @article{StrotmannFriedrichKreyenschmidtetal.2017, author = {Strotmann, C. and Friedrich, S. and Kreyenschmidt, J. and Teitscheid, P. and Ritter, G.}, title = {Comparing Food Provided and Wasted before and after Implementing Measures against Food Waste in Three Healthcare Food Service Facilities}, series = {Sustainability}, volume = {9}, journal = {Sustainability}, number = {8}, issn = {2071-1050}, doi = {10.3390/su9081409}, pages = {1409}, year = {2017}, language = {en} } @article{HSArshamianSchemmeretal.2010, author = {HS, Seo and Arshamian, A and Schemmer, K and Scheer, I and Sander, T and Ritter, G and Hummel, T.}, title = {Cross-modal integration between odors and abstract symbols.}, series = {Neurosci Lett.}, volume = {478}, journal = {Neurosci Lett.}, number = {3}, pages = {175 -- 178}, year = {2010}, language = {en} } @article{GoebelLangenBlumenthaletal.2015, author = {G{\"o}bel, Christine and Langen, Nina and Blumenthal, Antonia and Teitscheid, Petra and Ritter, Guido}, title = {Cutting Food Waste through Cooperation along the Food Supply Chain}, series = {Sustainability}, volume = {7}, journal = {Sustainability}, number = {2}, pages = {1429 -- 1445}, year = {2015}, language = {en} } @incollection{LangenRhozyelGoebeletal.2017, author = {Langen, Nina and Rhozyel, Mounaim and G{\"o}bel, Christine and Speck, Melanie and Engelmann, Tobias and Rohn, Holger and Teitscheid, Petra}, title = {Displaying Sustainability Related Information on Meals - The Role of Design and Information Depth from a Consumer's Perspective}, series = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, booktitle = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, pages = {349 -- 359}, year = {2017}, language = {en} } @article{KalhoffVossAbrametal.2020, author = {Kalhoff, Hermann and Voss, Susanne and Abram, Fiona and G{\"o}bel, Christine and L{\"u}cke, Thomas and Kersting, Mathilde}, title = {Fate of a food nudging intervention during the Corona-pandemic: unexpected shopping ban on a small clinic bistro.}, series = {European Journal of Clinical Nutrition}, volume = {75}, journal = {European Journal of Clinical Nutrition}, doi = {10.1038/s41430-020-00728-x}, pages = {209 -- 211}, year = {2020}, abstract = {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).

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 f{\"u}r Ern{\"a}hrung; 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.}, language = {en} } @incollection{GoebelTeitscheidFriedrichetal.2017, author = {G{\"o}bel, Christine and Teitscheid, Petra and Friedrich, Silke and Langen, Nina and Speck, Melanie and Engelmann, Tobias and Rohn, Holger}, title = {Implementing Sustainable Business Models in the Hospitality Sector with the Help of a Mission Statement}, series = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, booktitle = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, pages = {323 -- 328}, year = {2017}, language = {en} } @inproceedings{GoebelTeitscheidFriedrichetal.2017, author = {G{\"o}bel, C. and Teitscheid, P. and Friedrich, S. and Langen, N. and Speck, M. and Engelmann, T. and Rohn, H.}, title = {Implementing Sustainable Business Models in the Hospitality Sector with the Help of a Mission Statement}, series = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, booktitle = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, doi = {10.18461/pfsd.2017.1734}, pages = {323 -- 328}, year = {2017}, language = {en} } @article{GoebelTeitscheidFriedrichetal.2017, author = {G{\"o}bel, C. and Teitscheid, P. and Friedrich, S. and Langen, N. and Speck, M. and Engelmann, T. and Rohn, H.}, title = {Implementing sustainable business models in the hospitality sector with the help of a mission statement}, doi = {10.18461/ijfsd.v8i2.827}, year = {2017}, language = {en} } @article{StrotmannNiepagenkemperGoebeletal.2017, author = {Strotmann, Christina and Niepagenkemper, Linda and G{\"o}bel, Christine and Fl{\"u}gge, Fara and Friedrich, Silke and Kreyenschmidt, Judith and Ritter, Guido}, title = {Improving Transfer in the Food Sector by Applying a Target Audience-Centered Approach—The Development of a Nonprofit Marketing Campaign Guide Based on a Case Study of the LAV Platform 9(4)}, series = {Sustainability}, volume = {9}, journal = {Sustainability}, number = {4}, issn = {2071-1050}, doi = {10.3390/su9040512}, pages = {512 -- 537}, year = {2017}, language = {en} } @incollection{SpeckRohnEngelmannetal.2016, author = {Speck, Melanie and Rohn, Holger and Engelmann, Tobias and Teitscheid, Petra and Langen, Nina}, title = {Indicator-based assessment for meals.}, series = {Proceedings of the 20th Conference of the Environmental and Sustainability Management Accounting Network (EMAN}, booktitle = {Proceedings of the 20th Conference of the Environmental and Sustainability Management Accounting Network (EMAN}, address = {L{\"u}neburg}, pages = {231}, year = {2016}, language = {en} } @incollection{LangenBauskeDubraletal.2017, author = {Langen, Nina and Bauske, Emily and Dubral, Ricarda and G{\"o}bel, Christine and Speck, Melanie and Engelmann, Tobias and Rohn, Holger and Teitscheid, Petra}, title = {Interventions to Guide Consumers towards Sustainable Nutrition out-of-home - the Perspective of Caterers vs. Guests}, series = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, booktitle = {Proceedings in System Dynamics and Innovation in Food Networks 2017}, pages = {339 -- 348}, year = {2017}, language = {en} } @article{TeitscheidLettenmeierGoebeletal.2012, author = {Teitscheid, Petra and Lettenmeier, Michael and G{\"o}bel, Christine and Liedtke, Christa and Rohn, Holger}, title = {Material Footprint of a sustainable nutrition system 2050 - Need for dynamic innovations in production, consumption and politics, 6 th International European Forum (Igls-Forum) on System Dynamics and Innovation in Food Networks February 13-17, 2012 - Innsbruck-Igls, Austria}, series = {Rickert U, Schiefer G: Proceedings in System Dynamics and Innovation in Food Networks 2012}, journal = {Rickert U, Schiefer G: Proceedings in System Dynamics and Innovation in Food Networks 2012}, issn = {2194-511X}, pages = {574 -- 583}, year = {2012}, language = {en} } @article{LangenOhlhausenSteinmeieretal.2022, author = {Langen, Nina and Ohlhausen, Pascal and Steinmeier, Fara and Friedrich, Silke and Engelmann, Tobias and Speck, Melanie and Damerau, Kerstin and Rohn, Holger and Teitscheid, Petra}, title = {Nudges for more sustainable food choices in the out-of-home catering sector applied in real-world labs}, series = {Resources, Conservation and Recycling}, journal = {Resources, Conservation and Recycling}, doi = {10.1016/j.resconrec.2022.106167}, year = {2022}, abstract = {Food production is responsible for approximately 17\% of Germany's greenhouse gas (GHG) emissions. 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.}, language = {en} }
