Fishing and processing of live nephros for exportation

This was a pilot project aimed at defining conditions for efficient export of live lobsters. The project spanned the process from fishing to lobster marketing in Europe. The project succeeded in defining conditions for bringing live lobster from Hornafjörður to the market in Southern Europe. It was shown that it is possible to catch lobster in trawls for live export if it is ensured that precise quality categories take place on board the fishing vessel. Work processes were defined as minimizing discounts for short-term storage of lobster on land and for transport to the European market. A comparison with comparable Danish studies showed that survival was better in our process or 66% compared to 53%. However, there were higher discounts due to hake during trawling on Icelandic vessels, but this was supplemented by three times higher survival when transported ashore and short-term storage ashore (96 hours). It was shown that lobsters could be kept alive without discounts for up to 48 hours when transported to a foreign market. It was estimated that lobsters would need to live for at least 37 hours. in transit to reach the consumer in Europe. Prices in foreign markets were in line with market analysis. The project has therefore defined a work process that can be built on to start selling live lobster on the market in Southern Europe. However, it is necessary to master the catch of lobster traps in order to increase survival even further and reduce time-consuming sorting work in the process.

This research project was initiated to define conditions for optimized export procedure for Icelandic live nephrops. The project was based on holistic approach spanning the progress from catching nephrops to marketing of the live product in Europe. We were able to define conditions allowing for live export nephrops from Hornafjordur to Europe. We showed that it is possible to export live trawl fished nephrops but only after rigorous quality assessment. We defined workflow allowing for high survival rate of live nephrops during transportation and storage prior to exporting. Comparison with similar Danish project revealed that our setup allowed for higher survival rate or 66% compared to 53%. The survival rate after Icelandic trawl catching was lower than after Danish trawl catching. Survival rate during transportation and short time storage (96 hours) was three times higher in our setup. It was possible to keep nephrops alive for 48 hours in the export packaging, while it was assumed that such export would typically take up to 37 hours. Prices obtained in the pilot marketing tests were in the price range expected based on our marketing analysis. We have therefore defined a procedure suitable for initiating commercial export of live nephrops to Europe. However it is critical to build up capacity for creeling of nephrops in Icelandic waters to ensure higher survival rates and longer storage time of the live products. This would also reduce the extensive quality assessment needed if the nephrops is trawled.

Untapped opportunity in the Icelandic fishing industry

Þorsteinn Már Baldvinsson, CEO of Samherji, and Sveinn Margeirsson, division manager at Matís, discuss opportunities in the Icelandic fisheries sector at an open meeting on Thursday. Dec 3 at 08:30 at Hilton Reykjavik Nordica Hotel, Suðurlandsbraut 2.

The meeting is hosted by Matís, the AVS fund and the Association of Fish Processing Plants.

The aim of the meeting is to shed light on opportunities and possibilities for better utilization and increased value. Icelanders are at the forefront of the utilization of marine resources and have strong and powerful fisheries companies with years of experience in meeting the needs of the market. But our raw material is a limited resource and therefore it is necessary to make the best use of it and create great value from it.

It could be that we are missing out on opportunities by often exporting unprocessed raw materials, we can make better use of our well-educated people in development and marketing, we can make better use of the opportunities inherent in the source of the raw material, and so on.

This meeting can shed light on the future possibilities of the Icelandic fisheries sector.

Traditional foods 13 European countries

Matís participates in the European network of excellence EuroFIR on food databases and chemical content of food. A workshop on traditional foods in Europe has now been completed.

Five traditional foods were selected in each country, the production process was defined and then a number of nutrients were measured in the products. The Icelandic food was skyr, ham, pickled blood butter, dried fish and a delicious shark. This project was carried out in collaboration with the Agricultural University of Iceland.

Information on traditional foods has now been compiled and published in a loose-leaf folder. The text is in both English and the language of the country in question. The history of the food, its production and nutritional value are discussed. The information has been published on the EuroFIR project website and can be accessed at:

eurofir.org

A general report on traditional European food was also published and can be accessed at:

Importance of cooling: from tickets to the market - Meeting in the Westman Islands

Introductory meeting for the fishing industry and carriers in the Westman Islands - Matís ohf. and the University of Iceland.

Thursday 26 November An introductory meeting will be held on the results of the cooling projects Kælibót and Chill-on and Hermun kæliferla. Extensive experiments have been carried out in the field of cooling catfish from the market. Participants in the project are connected to different links in the chain: raw material handling, processing, transport and marketing. Various experiments from extensive research on cooling fish will be presented. The experiments were performed in the winter of 2008-2009 under real conditions. A comparison has been made of:

  • cooling capacity of different ice media and machines for their production
  • cooling methods during processing (liquid and erosive cooling)
  • different packaging for product packaging
  • different transport routes (ships and flights) and the effect of improved temperature control on the transport of chilled products.

Experiments are now underway where the best methods for each link in the chain are selected together and the whole chain is run in one experiment under real conditions. Transport processes have been mapped in terms of time and temperature, and refrigeration simulators will be used to set up those processes for storing products. In this way, the necessary measurements can be performed without the transfer from the sampling site to the laboratory interfering with the results. At the same time, transport to foreign markets will be imitated by sending fish to the Westman Islands. Foreign participants Chill-on (www.chill-on.com/) have arrived in the country and will test their technology with this transfer.

Nordic Values in the Food Sector - Matís is organizing a Nordic conference on 15-17. nov nk.

The food industry plays an important role in the Nordic countries. In recent years, emphasis has been placed on the safety, sustainability, purity, hygiene and traceability of food produced in the area.

The conference will focus on these key issues in an era of growing international trade in raw materials and processed foods. The connection between food and the origins, culture and cuisine of the Nordic countries will also be discussed.

Topics at the conference will include:

  • Food security in the world of globalization
  • Interaction between animal welfare, health and food analysis in the market
  • Innovation in the food sector
  • Nordic culture and identity vs. innovation
  • The position of the Nordic food industry and the potential of the world market

The aim is to provide an overview of the position of the Nordic food industry in terms of international security and innovation. Efforts will be made to define challenges and future opportunities for Nordic food.

Do consumers and industry share the authorities' emphasis on sustainability, quality, purity, health and traceability? Which items are considered most important? How do consumers perceive food safety messages? How can the Nordic countries contribute to the international arena in the future in terms of resource management and use? Where are international standards heading and how can policy makers and industry stakeholders influence them? Are Nordic governments and private companies creating technical barriers due to their emphasis on concepts such as safety, cleanliness, health, sustainability and traceability? What future opportunities and challenges does Nordic food face?

Representatives from different stakeholders will discuss these issues from their point of view. The conference is intended for the food industry, scientists, consumer organizations, policy makers and the authorities. The results will be published on the conference website.

Heat transfer model of halibut, freezing and thawing - an opportunity for further value creation

The Matís report "Freezing and thawing of halibut - experiments and CFD simulation" has been published, which was prepared in the project Simulation of cooling processes. 

The freezing and thawing of halibut was experimentally studied and CFD models were constructed using the thermal and hydrological software FLUENT. The project has already demonstrated the unequivocal utility of such models for the transport processes of fresh produce, but the results of this report show that the same applies to frozen products. 

In the freezing experiment, whole pallets of semi-frozen halibut were placed in a cold store and the air temperature and the temperature of halibut in different places on the pallet were measured with thermometers. The time taken for the halibut to freeze from -10 to -5 ° C below -15 ° C ranged from one to four days depending on the location of the pallet.

height in a single halibut bag after 10 hours. heat load (12.6 ° C ambient temperature) according to CFD model. The initial product temperature was -26.0 ° C

In thawing experiments, both individual bags and twenty bags, stacked on pallets, were examined in the temperature-controlled cold rooms of Matís and UI. Heating of a frozen product was mapped under conditions that may occur during unloading from freezer trawlers or 10 - 20 ° C air temperature. The results of the experiments were compared with the results of three-dimensional heat transfer models, and there was generally a good agreement between them. At 10 p.m. storage at 12.6 ° C air temperature raised the temperature in individual bags from about -26 ° C to approx. -5 ° C. At such a long temperature load, the temperature in pallet bags rose from -22.5 ° C to -17 to -3 ° C, which shows how homogeneous the heat distribution can be with prolonged heat load. The results of the CFD model showed that 10 m / s wind during loading significantly accelerates the thawing of frozen fish on pallets.

Fish market for the general public

An interesting summary has been presented about the possibilities of a fish market for the general public, where visitors and pedestrians can get to know the inexhaustible possibilities of Icelandic seafood and get acquainted with the products and buy exciting ingredients for cooking.

Why is it not common in this country for the public to be able to buy fresh fish on the quayside or at the fish market? Iceland is known for its great and good fishing grounds and fish products of high quality. Why not make more of an experience related to the fish, both for Icelanders and for tourists? Many people are interested in the idea of a fish market, but for some reason it has not been implemented.

The AVS project "Fish Market for the Public" is now complete. The project was about exploring the basis for establishing fish markets in Iceland for the general public and tourists. Proposals were also made on how to handle such a market. The main purpose was to encourage the establishment of (retail) fish markets around the country and thereby strengthen the connection between consumers and seafood. There has been a lot of interest in the project and everything points to such a market being established in Reykjavík soon.

These proposals review the state of fish markets in Iceland and what "retail fish markets" can offer. Examples of fish markets abroad are taken, various ways of setting up a retail fish market are reviewed, and the main steps that need to be kept in mind when setting out are reviewed. Finally, an example is taken of the process of original idea work for the establishment of a retail fish market in Reykjavík.

The authors hope that this summary will spark interest in and contribute to the establishment of fish markets for the general public across the country.
