    Vattenrening för ökad hygien vid odling av frilandsgrönsaker och bär2017Other (Other (popular science, discussion, etc.))
    Abstract [sv]

    Under senare år har ett flertal utbrottmed magsjuka kopplats till konsumtionav grönsaker, frukt och bär. Sjukdomsframkallandebakterier och virus, såsomnorovirus, Salmonella, toxinproducerandeE. coli, Campylobacter och Listeria. kanspridas från bevattningsvatten via grö-dan till människor och orsaka sjukdom.Smittat bevattningsvatten kan därförförorena frilandsproducerade grönsakeroch bär. Det är alltås viktigt att hakontroll på bevattningsvattnets kvalitet.Dessutom är det viktigt att känna tillvilken typ av kultur som vattnet skaanvändas till, eftersom risken för vidaresmitta till människor varierar mellanolika typer av kulturer. T.ex. är det störrerisk att använda kontaminerat vatten tillkulturer som äts råa utan uppvärmninghos livsmedelsproducenten eller konsument,eftersom det då inte finns nå-gon möjlighet att avdöda de oönskademikroorganismerna i ett efterföljandesteg. Genom rätt hantering och adekvatbehandling av bevattningsvattnetkan dess hygieniska kvalitet förbättras.Ibland finns det möjlighet för odlarenatt byta vattenkälla, men då detta inte ärpraktiskt möjligt kan det kontamineradevattnet renas innan bevattning. I dettafaktablad beskrivs två grundläggandetekniker för rening av bevattningsvattenvid frilandsproduktion, nämligen fotokemi(fotokatalys, UV) och filtrering(mekanisk filtrering, långsamfiltrering).Dessa används för att minska risken försmittspridning med bevattningsvattnet.

    Abstract [en]

    The food value chain system in Sweden is well established making it hard for small companies to develop new products and even harder to create new food supply systems Obstacles could lay at the beginning of the chain (food production or processing), at the end (marketing, consumer) or could even be related to the legislative regulation framing the food supply chain. Smaller actors often lack resources and networks to develop their sector. However, their degree of creativity, innovativeness, and engagement is high, and their energy is needed in the development of new sustainable food value chains.

    The aim of this project was to develop and apply a methodology for evaluating food value chains, focusing on profitable small-scale production systems in Sweden that show potential for fast development of new products that quickly reach the market. The work also included identifying Swedish raw food materials with growth potential and to identify how they could come into greater demand. Ten food value chains with high development potential in Sweden and for export were mapped and the main bottlenecks briefly described. Three food chains where selected based on a potential-difficulty-benefit matrix. The three selected food value chains were: (i) Hops, (ii) Swedish forest berries, and (iii) Land-based fish farming. These three food value chains where further studied looking at the whole value chain, from production to end consumer. Through literature review and contacts with relevant stakeholders (telephone interview, face-to-face interview, or workshop) the bottlenecks were clarified and potential solutions for increased demand where identified.

    Swedish hops production is carried out by passionate and engaged smaller actors, mostly on a hobby level, and the hops is used as an ingredient for beer. Germany and the USA produce about 75% of the worldwide production These hops varieties are not adapted to the Swedish climate and therefore result in a low volume and poor quality. However, domestic varieties have been grown in the past giving better yield under Swedish climate conditions. More work is needed to characterize the quality of Swedish hops. At the present time, knowledge about the characteristics of Swedish hops is low, explaining the lack of interest from brewers. In Sweden most hops are harvested by hand, making it nearly impossible to be profitable on the market. The mechanization of the harvesting step is necessary to move Swedish hops from a hobby to a commercial activity. No solutions are available on the Swedish market, RISE together with SLU is looking to develop a hops harvester fulfilling Swedish and EU regulations and adapted to small scale cultivation. At the end of the value chain, innovative products could increase the need for Swedish hops, for example by developing beers brewed with fresh hops. Moreover, hops have antiseptic characteristics and could potentially be used in other food products than beer.

    Only about four percent of the berries that are produced by the Swedish forests every year are picked. The largest volumes picked are for bilberry (Swedish: blåbär), lingonberry, and cloudberry and most of them are washed and frozen in Sweden. Processing of berries, however, has to a large extent moved out of the country while the products produced for the Swedish market are quite traditional, low-processed foods such as jams, juices and dessert soups. The majority of the Swedish berries mainly bilberries due to their nutritional content are exported and are further processed into value added powders or extracts in Asia and Europe. In Sweden this kind of value chain is under developed largely due to knowledge barriers and to the currently very traditional market. However, there is a great consumer interest in berries and they have a perceived healthiness also in Sweden. Consumers are also increasingly aware of the origin of berries used as ingredients in products such as jams, purees and juice, as well as in health food products. To fill this gap between consumer interest/demand and raw materials available new businesses can be developed. To facilitate such development there is a need for knowledge generation and transfer along the whole value chain (picking, processing, product development and consumer studies), which can be generated by starting up new innovation and research projects. It is also of importance to facilitate networking, for example in the ‘berry network’ (coordinated by RISE), as the creation of a new value chain will require different businesses to cooperate. Also, product development projects will need support for testing, pilot production, and possibly in finding investment funding for new equipment.

    Land-based fish farming is small in comparison to traditional fish farming in Sweden, but several actors see a great potential in this system which has a lower impact on the environment compared to conventional fish farms. For instance, the Swedish farmer federation (LRF) has invested in a land-based fish farm recently. As in other EU-countries, the number of active farms in Sweden is decreasing and some see the potential to recycle unused animal stables into fish farms. A major bottleneck for land-based fish farming is current legislation as it is based on conventional fish farming and therefore does not consider the environmental benefits of land-based systems. Knowledge should be spread to relevant authorities and policy makers to open a dialog and facilitate the development of a relevant regulatory framework. Regarding the production phase, access to sustainably produced feed and technical competence are lacking. Moreover, as the technology is costly learning through trial and error would not be recommended. A testbed dedicated to land-based fish farming could support companies who wish to try modifications to their system. Furthermore, smaller producers have difficulties in finding processing solutions for their products; e.g. slaughterhouses and conditioning. Two potential solutions would be to develop a land-based fish farm cooperative and/or mobile systems that could take care of smaller productions. Finally, the competition on the market is tough as land-based fishes are competing with large-scale conventional fish farms from Norway and Asia. To overcome this bottleneck, the sector could develop its own certification as well as increasing the consumers awareness and knowledge.

    Some conclusions could be applied to all the studied food chains. For instance, each value chain can be seen as a puzzle with many pieces. In order to develop new food value chains many separate pieces need to fall into place. Therefore, it is necessary to increase collaboration between stakeholders but also to have a stakeholder driven coordination of this collaboration. The stakeholders within the developing value chains often do not have all the resources to carry out this task, especially if they are small businesses. The development of cooperatives also seems to be a solution to overcome bottlenecks in the studied food chains. Likewise, logistics in the developing value chains have a great margin for improvement. Furthermore, this project focused on value chains where food commodities are the end product but investigating the potential for non-food uses would also be of interest.

    The method used in this project can be replicated to other value chains with potential of development. It would help the users to get a holistic view of the current bottlenecks and facilitate contact between stakeholders. The list of bottlenecks can be followed up and used as an indicator to evaluate if the value chain in moving forward.

    Relationship between anthocyanins, proanthocyanidins, and cell wall polysaccharides in grapes and red wines. A current state-of-art review2022In: Critical reviews in food science and nutrition, ISSN 1040-8398, E-ISSN 1549-7852, Vol. 62, no 28, p. 7743-Article, review/survey (Refereed)
    Abstract [en]

    Numerous research studies have evaluated factors influencing the nature and levels of phenolics and polysaccharides in food matrices. However, in grape and wines most of these works have approach these classes of compounds individually. In recent years, the number of publications interconnecting classes have increased dramatically. The present review relates the last decade’s findings on the relationship between phenolics and polysaccharides from grapes, throughout the entire winemaking process up to evaluating the impact of their relationship on the red wine sensory perception. The combination and interconnection of the most recent research studies, from single interactions in model wines to the investigation of the formation of complex macromolecules, brings the perfect story line to relate the relationship between phenolics and polysaccharides from the vineyard to the glass. Grape pectin is highly reactive toward grape and grape derived phenolics. Differences between grape cultivars or changes during grape ripeness will affect the extractability of these compounds into the wines. Therefore, the nature of the grape components will be crucial to understand the subsequent reactions occurring between phenolics and polysaccharide of the corresponding wines. It has been demonstrated that they can form very complex macromolecules which affect wine color, stability and sensory properties.
