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.

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.

The effect of liquid cooling at processing and different cooling techniques during transport of cod (Gadus morhua) fillets

The purpose of the experiments was to investigate the effect of different refrigeration techniques and the effect of temperature fluctuations on the quality and shelf life of cod fillets. The following cooling technology was investigated: Liquid cooling in brine during processing based on no cooling and the effect of temperature fluctuations during storage compared to a constant temperature (-1 ° C). In addition, the effects of using ice mats and dry ice on the storage of the wrecks were investigated. Temperature changes were monitored by temperature sensors at all levels. Samples were quality assessed by sensory evaluation, microbial and chemical measurements for up to 14 days from fishing (11 days from processing and packaging). Different treatment resulted in different freshness times and shelf life according to sensory evaluation. Groups that were liquid-cooled during processing had a shelf life of about 2-3 days shorter than fillets that were not cooled in this way. The reasons for this can be traced to the fact that the cooling brine contained a considerable amount of microorganisms, including the destructive bacterium Photobacterium phosphoreum, which is a very active producer of trimethylamine (TMA). Comparison of liquid-cooled fillets showed that the use of dry ice prolonged shelf life by 1-2 days compared to ice mats. Storage at -1 ° C did not have a significant effect on freshness time and shelf life compared to fillets where temperature fluctuations were applied according to sensory evaluation. The results of microbial and chemical measurements were consistent with these results.

The aim of the experiment was to investigate the effects of different cooling techniques and temperature fluctuations on the storage life of cod fillets. The following cooling techniques were studied: liquid cooling in brine at plant as compared to no special cooling at processing. The effect of real temperature (RTS) simulation during storage was compared to a steady storage temperature at -1 ° C. Additionally, the influence of using either dry ice or ice packs during storage was studied. The temperature history of each group was studied using temperature loggings. The samples were analyzed with sensory evaluation, microbial and chemical methods for up to 14 days from catch (11 days from packaging). The different treatments of the groups resulted in different lengths of freshness period and maximum shelf life according to sensory evaluation. Liquid cooling resulted in a 2-3 days shorter maximum shelf life than the group that was not receiving liquid cooling. This could be attributed to the fact that the cooling brine carried considerable amounts of microbes including the spoilage bacterium Photobacterium phosphoreum which is an active producer of trimethylamine (TMA). Comparison of the groups receiving liquid cooling showed that dry ice appeared to extend the shelf life of 1-2 days as compared to ice packs. Storage at -1 ° C did not have much influence on the freshness period or maximum shelf life. These results were confirmed by total volatile bases (TVB-N) and TMA analysis and microbial counts.

Development of industrialized cod farming: Control of growth and sexual maturation with advanced lighting equipment / Improved lighting technology for regulating sexual maturation of farmed cod

The overall goal of the project was to improve farming techniques in cod farming with the use of a new type of light in the goal of controlling the sexual maturity of cod. These are lights that emit a single wavelength that is better distributed over the aqueous phase compared to halogen lights that are traditionally used, and this new type of light has proven to be very effective in preliminary research. It was also investigated whether light control immediately at the juvenile stage could possibly contribute to this effect in the heifer fire. Continuous treatment with the lights at the juvenile stage did not affect the juveniles' growth, but there were indications of fewer growth defects in the juveniles. However, light control at the juvenile stage seemed to have a negative effect on the growth of the fish after transport to sea cages, in addition to which there were many unexplained declines in that group. Light control of fish in cages had a positive effect on the growth of the fish compared to fish kept during the natural light cycle in sea cage farming. The project also developed and standardized new methods for measuring the concentration of growth hormones in cod, and the method proved to be both sensitive and safe. The relationship between growth rate and concentration of growth hormone in the blood of the fish could not be demonstrated in this study, but the method offers great future potential in studies of, for example, the growth rate of wild cod. The project also carried out a detailed study of the effects of seaweed farming on the diversity and species composition of benthic fauna under pens. Extensive changes in the species composition of benthic animals were observed despite a small load associated with fire in the pens over a three-year period.

The overall aim of the project was to improve cod farming technology by delaying sexual maturation of cod by the use of a new lighting technology. The novel lights emit only one wavelength that is more effectively dispersed in water compared to the metal halogen lights traditionally used. Continuous manipulation using the novel light technology during the juvenile stage did not affect fish growth or survival. Indications of reduced frequency of deformities were however observed in this group. Light manipulation during the juvenile stage was further found to negatively affect fish growth following transfer to sea cages and significantly higher unexplained loss of fish was observed in this group. Continuous light manipulation during on growing in sea cages resulted in significantly improved growth of the fish compared with fish exposed to ambient light. New methods were furthermore developed for measuring the concentration of growth hormones in cod. A relationship between fish growth and the concentration of growth hormones could not be established. The method however provides an important tool for future studies of the growth of eg wild cod. Detailed studies of species diversity in bottom layers below the sea cages were also carried out, revealing extensive changes in species composition during the three-year study.
