In the recent years, the consumer choices have been focused on health-promoting plant-based food and their preferences are oriented towards regional foodstuff from local productions. Therefore, an important factor for vegetables grown Trentino-Alto Adige (Italy) is to point out the added value of alpine farming to evaluate the nutritional values of farming products. Omics technologies (e.g. genomics, transcriptomics, proteomics and metabolomics) are aimed at investigating the assessment of different pools of molecules and how they are translated into the structure, function, and dynamics of a biological system or systems in order to provide a comprehensive characterization of a specific organism. Research use the omics techniques to exhaustively understand the functionality of food components. Several sophisticated chromatographic methods, spectroscopic techniques and chemometric tools are applied to give an insight into a comprehensive overview of the intrinsic quality, typicality and regionality of specific plant-based foods in the present PhD thesis: apples and potatoes. The quality of these foods is evaluated by quantifying the secondary metabolites to investigate their nutraceutical values. The aim of this PhD project is to use several analytical techniques (LC-MS, UV-VIS) that are capable of comprehensively characterizing the food metabolome with particular emphasis on those components with high nutritional values. The data analysis and data handling of omics data requires advanced bioinformatic, statistical, and chemometric tools. Potatoes and apples are chosen as target matrices for these studies for their relevance in the local economy and for the peculiar chemical composition of particular interest for their health-promoting proprieties. The information is acquired using several sophisticated chromatographic and spectroscopic techniques, such as ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC– MS/MS) and UV/VIS. It is integrated to chemometric approaches (principal component analysis (PCA), partial least square regression (PLS), and data fusion) to achieve a comprehensive targeted chemical characterization. The sampling procedures gathers, in the case of the potatoes study, reference cultivars that may be found in the common retailers of Trentino/Alto-Adige and different production areas, the apples of 22 cultivars were harvest from the fields of the Laimburg Research Centre (Vadena, Italy) to guaranty comparability of the obtained data. Our results may be used as solid foundation for a reliable evaluation of apples and potatoes healthy "potential" value based on cutting-edge techniques, which are capable of providing comprehensive data regarding the alpine food quality parameters with high efficiency and reliability

Malmö vill enligt sitt eget miljöprogram vara “Sveriges klimatsmartaste stad”. Alla livsmedel som köps in av kommunen ska vara ekologiska, och klimatgasutsläppen från maten ha minskat med 40% före utgången av 2020. Det ekologiska målet ser ut att kunna nås, men klimatgasutsläppen har endast gått ner med 15% i skrivande stund. Staden driver nu en ny satsning för att klara målsättningen. Denna undersökning granskar det förfarande som Malmö stads miljöförvaltning tagit fram och sätter det i relation till forskning om klimatkommunikation och beteendeförändring. Det är vanligt att utvärderingar av utbildningar fokuserar på deltagarnas attityd till utbildningen, istället för de beteendeförändringar som utbildningen uppmanar till. Genom gruppintervjuer med utbildare och projektdeltagare, samt innehållsanalys av utbildningsmaterialet söker undersökningen svar på frågan: leder miljöförvaltningens utbildning till ett förändrat beteende hos utbildningens målgrupp? Även om vi utifrån respondenterna kan konstatera att få konkreta förändringar hittills har skett i verksamheterna, har vi kunnat identifiera hinder, förbättringsåtgärder och kartlägga hur deltagarna på olika sätt förhåller sig till utbildningarna och till målet. Vi konstaterar att metoden för hur satsningen ska bedrivas inte använder sig av ett teoretiskt ramverk eller är konsekvent förankrad i vetenskap. Vi konstaterar att kommunen har en stark position för att verkliggöra miljövänligt beteende hos sina anställda, men att kommunen underutnyttjar potentialen. Konsekvenser och möjligheter diskuteras. / Malmö, according to its own environmental program, wants to be "Sweden's most climate friendly city". All food purchased from the municipality should be organic and the greenhouse gas emissions should decreased by 40% by the end of 2020. The ecological target seems to be achievable, but climate emissions have only fallen by 15% at the time of writing. The city is now running a new venture to meet the goals. This study examines the procedure developed by Malmö City Environmental Management in relation to research on climate communication and behavioral change.It is common for evaluations of education to focus on the attitudes of the participants, rather than the behavioral changes that the education encourages. Through group interviews with educators and project participants, as well as content analysis of the educational material, the survey seeks to answer the question: Does the management of the environmental administration lead to a change in behavior in the education target group?Even though, according to the respondents, few changes have taken place so far, we have been able to identify obstacles, improvement measures and map how the participants relate to the education and the goal in different ways. We note thatthe method of conducting the venture does not use a theoretical framework or is consistently rooted in science. We note that the municipality has a strong position to realize environmentally friendly behavior among its employees, but that the municipality underuses the potential. Consequences and opportunities is discussed.

Individual food choices have a considerable impact on public health and the environment. The incidence of nutrition-related diseases has been continuously increasing during the last decades. Diets higher in plant-based foods have shown to be healthier and more environmentally sustainable.Many urban social innovation projects based on citizen engagement and community building are able to influence food consumption habits. However, there is a large variety of projects, which target specific population groups and focus on different sustainability issues. To understand how social innovation projects located in Germany, and especially Berlin, use citizen engagement and community creation to encourage nutritious and sustainable food choices, the research team conducted a qualitative research study consisting of semi-structured interviews and participant observations. The results were compared and validated using different social change, social innovation, network and leadership theories. When people with various backgrounds come together over a shared purpose and interact with each other, they can influence each other’s opinions and behaviors. A physical community setting was shown to be efficient to create awareness about sustainable and nutritious food choices. In order to include all population groups, citizens need to feel heard and understood, and have to be directly engaged in the decision-making process. A need for a leadership figure or a democratic leadership group is highlighted, and a combination of ‘transformational leadership’ and ‘authentic leadership’ styles proved to be the most effective. Urban food social innovation projects tend to cooperate with each other, as well as with other leaders and organizations, influencing them and serving as role models. These findings can help social innovation projects that implement citizen engagement and community building practices to efficiently promote nutritious and plant-based food choices among an urban population. Since this study is based on a limited number of organizations in Berlin and other regions of Germany, further research in other urban and/or rural environments is needed.
