Opportunities for the North Atlantic - Matís participates in the NORA conference in Reykjavík

From 18.-19. May, a conference will be held at the Hilton Reykjavík Nordica Hotel on behalf of the Nordic Atlantic Committee (NORA).

The purpose of this conference is to examine and explore the possibility of co-operation between parties that in one way or another have interests in the North Atlantic. Rannveig Björnsdóttir will give a talk, while Sjöfn Sigurgísladóttir, CEO of Matís, will chair one of the conference seminars.

The agenda of the conference can be found here.

NORA or the Nordic Atlantic Committee is part of the Nordic Council of Ministers and is part of Nordic co-operation in the field of regional affairs and regional co-operation. The Nordic co-operation environment and project-oriented work create NORA's good foundation for cross-border co-operation, based on Nordic goals and values.

NORA's activities are funded by the Nordic Council of Ministers and contribute from the four participating countries, the Faroe Islands, Greenland, Iceland and Norway.

The NORA Committee consists of three members from each of the participating countries, and the committee formulates a policy for NORA's activities for several years at a time.

NORA's head office is located in Þórshöfn in the Faroe Islands. In the other member countries, Iceland, Greenland and southern Norway, and western and northern Norway, national offices and contacts operate.

NORA contributes to strengthening co-operation in the North Atlantic area to make it a strong Nordic region, characterized by strong and sustainable development. This is done, among other things, by strengthening co-operation between the business community and research and development activities across borders.

It is therefore NORA's task:

  • to create a political and professional forum for discussion on solutions and policy-making and joint entrepreneurship in the North Atlantic area.
  • to establish and mediate project collaboration
  • to work towards development in accordance with the Nordic goals for sustainability.
  • to develop NORA as an attractive platform for Nordic co-operation with neighboring countries.

Reform of the food value chain

It is important to consider all aspects of the food value chain because each chain is never stronger than its weakest link.

The main results of the project "Reforms in the food value chain" have now been compiled in a report and published on Matís' website and can be found here along with detailed reports on Matís' aspects of the project.

The project was led by the Confederation of Icelandic Industries and carried out in collaboration with Kaupás, Norðlenska, Sláturfélag Suðurlands, the Research Center of the store, Matís and AGR action analysis.

The Technology Development Fund supported the project. The project focused on the process of meat products, which is a rather complex processing and requires both cooling and in some cases heating, throughout the processing process and throughout the store. Nevertheless, the results should be useful in other sectors of food processing.

Food manufacturers are encouraged to familiarize themselves with the contents of the report.

Matís has also published three other reports on individual aspects of the project; Product process mapping and product managementThe effect of the cooling chain on the shrinkage of meat together Suggestions for project descriptions for meat refrigeration chains.

Once again, it is confirmed that Icelandic seafood is clean and unpolluted!

A report has been published from Matís ohf. which is called Undesirable substances in seafood products - results from the Icelandic marine monitoring activities.

The report, which can be found here, shows the results of measurements of the amount of toxic pollutants in Icelandic seafood in 2008 and is part of a continuous monitoring project funded by the Ministry of Fisheries and Agriculture and has been ongoing since 2003. As in previous years of monitoring, the results of 2008 show that an edible part of fish caught in Icelandic waters contains very small amounts of organic pollutants such as dioxins, dioxin-like PCBs and pesticides (insecticides and plant toxins), compared to the maximums recognized by European countries. Oil and meal made from blue whiting, however, must be close to or exceed the permissible limits for certain substances. Cod liver can also exceed the permitted limits.

The data collected year after year in this project is used to build an increasingly accurate database on the state of Icelandic marine products with regard to pollutants. The report is in English and is accessible on Matís' website so that it can be used by producers, exporters, the government and others to promote the safety and wholesomeness of Icelandic fish products.

The results of measurements of cod liver, fishmeal and fish oil for feed preparation confirm the need to closely monitor the levels of persistent organic pollutants such as dioxins, PCBs and pesticides in these products in the spring. The concentration of the substances depends on the nutritional status of the pelagic fish stocks from which the products are processed and reaches its peak during the spawning season. The levels of dioxins and dioxin-like PCBs as well as individual pesticides stop exceeding the EU's permitted levels. This is especially true for blue whiting products.

A graphical presentation of the results of the monitoring project can be accessed on Matís' website via the link "Icelandic seafood - clean and unpolluted“.

The authors of the report are Hrönn Ólína Jörundsdóttir, Katrín Hauksdóttir, Natasa Desnica and Helga Gunnlaugsdóttir. The project manager is Helga Gunnlaugsdóttir, who provides further information, helga.gunnlaugsdottir@matis.is.

Are you creating skyr?

Matís is looking for collaboration with parties that produce skyr in a traditional way.

Skyr is a traditional Icelandic product that seems to have been made in Iceland since the settlement, but a dairy product under this same name was then known in all the Nordic countries. Skyrgerð, however, seems to have been preserved only in Iceland. Probably the sky during the settlement era has been different from what we know today, both more acidic and thinner. The production of skyr has changed significantly in the last century with the advent of its factory production. Various versions are now available from the factory
skyri, they all have in common that they are quite different from the homemade ones.

Skyr is an important part of our cultural heritage in Iceland and it is therefore important to gain more knowledge about this product. Nevertheless, little research has been done on traditional skyr and its diversity. Matís is currently seeking research on the composition and properties of traditional skyr and is therefore looking for collaboration with parties that still practice skyr in the traditional way.

Undesirable substances in seafood products - results from the Icelandic marine monitoring activities year 2008

In 2003, at the initiative of the Ministry of Fisheries, monitoring of undesirable substances in marine products began, both products intended for human consumption and products for the fish oil and flour industry. The purpose of the monitoring is to assess the condition of Icelandic marine products with regard to the amount of contaminants. The data collected in the monitoring project will also be used in risk assessment and to build up a database on contaminants in the Icelandic ecosystem. Coverage of contaminants in marine products, both in the mainstream media and in scientific journals, has many times demanded the response of the Icelandic government. It is necessary to have scientific results available that demonstrate the actual condition of Icelandic seafood in order to prevent damage that may result from such coverage. Furthermore, the limits of contaminants are under constant review and it is important for Icelanders to participate in such a review and support their case with scientific data. This shows the importance of regular monitoring and that Iceland conducts independent research on such an important issue as marine product pollution. This report is a summary of the results of the monitoring in 2008. Assessment of the state of Icelandic marine products with regard to contaminants is a long-term project and will only be carried out through continuous monitoring. Every year, the missing data is carefully reviewed and the aim is to fill in the blanks. In 2008, the following were measured: dioxins, dioxin-like PCBs and PCB substances, PBDEs, PAHs as well as ten different types of pesticides, in marine products intended for human consumption as well as products for the fish oil and flour industries. A special effort was made to measure PBDE and PAH substances in 2008 and very few of these substances were measured in Icelandic seafood. As before, a small amount of undesirable substances was generally measured in Icelandic seafood in 2008. Oil and flour made from blue whiting, however, tend to be close to or exceed the permitted limits for certain substances.

This project was started in 2003 at the request of the Icelandic Ministry of Fisheries and Agriculture. Until then, monitoring of undesirable substances in the edible portion of marine catches had been rather limited in Iceland. The purpose of the project is to gather information and evaluate the status of Icelandic seafood products in terms of undesirable substances. The information will also be utilized for a risk assessment and gathering of reference data. This report summarizes the results obtained in 2008 for the monitoring of various undesirable substances in the edible part of marine catches, fish meal and fish oil for feed. The monitoring began in 2003 and has now been carried out for five consecutive years. The evaluation of the status of the Icelandic seafood products in terms of undesirable substances is a long term project which can only be reached through continuous monitoring. For this reason, we carefully select which undesirable substances are measured in the various seafood samples each year with the aim to fill in the gaps in the available data over couple of year time. In 2008, data was collected on dioxins, dioxin-like PCBs, marker PCBs, ten different types of pesticides, PBDEs and PAHs in the edible part of fish, fish liver, fish oil and meal for feed. Samples collected in 2008 generally contained low concentrations of undesirable substances. These results are in agreement with our previous results obtained in monitoring programs 2003-2007. This year (2008) special emphasis was placed on gathering information on PBDE and PAHs and the results reveal that these compounds are in very low amounts in fish and fish products and most PAHs are actually below detection limits. Blue whiting meal and oil can contain undesirable substances in concentration close to or exceeding the maximum level set by the EU.

Improved fertilization of halibut eggs

The main bottlenecks in sea fish farming are the early stages of development and the supply of quality eggs, larvae and juveniles. The egg quality of fish varies greatly and is mainly assessed by the fertilization rate and performance of eggs and larvae, but is controlled by various factors. It is very important for the management and performance of companies to be able to assess roe quality as soon as possible. The aim of this project was to define factors that affect the fertilization rate of halibut eggs and that can possibly be controlled. At the same time, experiments were carried out with different methods of fertilization where the amount of seaweed was changed or substances were added to the environment during fertilization. Fish in two spawning groups were followed up and extensive research was carried out on the characteristics and bacterial flora of roe doses. The results show that there is not much variability in the measures examined and there is no significant correlation with the fertilization rate, which indicates that they are unlikely to have a decisive effect on egg quality. However, the results indicate that the composition of the total bacterial flora and the composition of essential fatty acids are different in eggs with a higher fertilization rate and can therefore affect the quality of eggs. The main results of fertilization experiments indicate that the addition of glucose at a certain concentration in the roe environment can lead to a 10% increase in the fertilization rate of roe, which offers the possibility of a large increase in income for aquaculture companies. Extensive research is planned on the further effects of glucose admixture on roe performance as well as larval performance and quality.

The main bottle necks in intensive marine aquaculture are the first stages and the supply of high quality eggs, larvae and juveniles. Egg quality is highly variable and has been defined in many ways mainly the fertilization rate and the viability of fertilized eggs and larvae. Multiple factors affect egg quality and an early assessment of egg quality is of great importance for hatchery management. The objective of this work was to define indicators for halibut egg quality that could possibly be regulated. Furthermore, the effects of variable fertilization methods have been tested, that is, variable amounts of seawater and addition of various chemicals during fertilization. Batches of eggs were collected from two spawning groups and extensive examination carried out on their characteristics and bacterial composition. The results show very little variability in the factors examined and no correlation with the fertilization rate that indicates insignificant importance for egg quality. However, the bacterial composition and the fatty acid composition were different in the batches of eggs with higher fertilization rate compared to lower indicating its importance for egg quality. The fertilization experiments indicate that the use of a certain concentration of glucose during fertilization could result in 10% increase in the fertilization rate which could bring about an increased operation success for the aquaculture companies. Comprehensive studies are scheduled to further investigate the effect of additional glucose on egg viability and larval survival as well as quality.

The effect of cooling methods at processing and use of gel-packs on storage life of cod (Gadus morhua) loins - Effect of transport via air and sea on temperature control and retail-packaging on cod deterioration

The purpose of the experiments was to investigate the effect of different cooling during processing and temperature fluctuations in transport with and without a cooling mat on the shelf life of cod necks. In processing, it was compared to use no pre-cooling for filleting, liquid cooling and skin cooling (CBC) which is always liquid-cooled. The effect of simulated temperature fluctuations in transport temperature changes (RTS) was compared with storage at a constant temperature (-1 ° C). The effects of using a cooling mat in storage and transport were also assessed. Samples were quality assessed by sensory evaluation, microbial and chemical measurements. Temperature was monitored with thermometers. Skimmed cod fillets in foam plastic boxes were transported to Bremerhaven by air and ship, where they were repackaged in air and aerated packages (MAP) and stored at 1 ° C. Chemical and microbiological measurements were performed to monitor quality changes. The temperature of the erythema necrosis was lower than in the first 2 days of the experiment. The cooling mats had a certain effect of lowering the temperature when temperature fluctuations were in the process and lower temperatures were maintained throughout the storage period. However, the use did not affect the duration of freshness or shelf life according to sensory evaluation. The number of microorganisms was somewhat lower if temperature fluctuations occurred in the process, but there was little difference at a constant temperature. Storage at a constant, low temperature (-1 ° C) prolonged shelf life by approx. 3 days according to sensory evaluation and it was in accordance with microbial counts and measurements of TVB-N and TMA. Experiments in Bremerhaven showed that the number of microorganisms was generally lower when using aerated packaging compared to airborne fish. This was especially noticeable in the flying fish. The fish transported by ship was still stored for as long as the fish transported by air. This is due to the fact that the flying fish experienced greater temperature fluctuations during transport and its surface temperature measured 4 ° C on arrival in Bremerhaven. The transport time by ship was much longer (+48 hours) but the surface temperature was below 2 ° C on receipt. The use of cooling mats had little effect on the temperature during transport, but nevertheless the surface temperature was slightly lower in fish with cooling mats on arrival in Bremerhaven both by air and by ship.

The main aim of the experiment was to investigate the effects of different cooling techniques during processing and temperature fluctuations during transport on the storage life of cod loins with and without gel packs. The following cooling techniques were studied: combined blast and contact (CBC) cooling (with liquid cooling prior to the CBC cooling), only liquid cooling and where no special cooling was used prior to deskinning and trimming. The effect of real temperature simulation (RTS) during storage was compared to a steady storage temperature of -1 ° C. The samples were analyzed with sensory, microbial and chemical methods. The temperature was monitored from packaging using temperature loggers. CBC cooled loins were transported to Bremerhaven via air and ship freight after packaging in EPS boxes. The fish was repacked in air and modified atmosphere and stored at 1 ° C. Deteriorative changes were evaluated by microbial and chemical indicators. CBC cooling resulted in a lower temperature profile the first two days of the experiment. The use of gel packs lowered somewhat the temperature increase in the products when RTS was applied and lower temperature was maintained during the entire storage period. According to sensory evaluation, the use of gel packs did not result in prolonged freshness period or shelf life. According to microbial and chemical analysis no marked difference was seen whether gel packs were used or not in groups stored at a steady temperature. However, microbial counts were somewhat lower and slower formation of TVB-N and TMA occurred in RTS groups where gel packs were used compared to no gel packs. Storage at a steady -1 ° C resulted in extended shelf life of three days according to sensory evaluation. This was confirmed by microbial and chemical analysis as lower microbial counts, TVB-N and TMA values were generally obtained in the steady temperature group than in the group receiving the RTS treatment. The storage studies carried out at Bremerhaven on modified atmosphere vs. air packed loins showed generally lower microbial counts, especially in the air transported fish. Deterioration process of air and sea freight fish was however similar. Re-packaging of sea freight fish at a later stage did not significantly affect its deteriorative process compared to re-packed air freight fish. This might be due to the fact, that the air freight fish was subject to high temperatures during transport and surface temperature reached over 4 ° C. The sea freight fish had a much longer transport phase, but arrived with surface temperatures below 2 ° C. This shows that not only the time of re-packaging but also the temperature profile during transport are important factors influencing the deteriorative process and shelf life. Gel packs did not have significant cooling effect in this experiment. However the surface temperature in boxes with a gel pack was slightly lower than in boxes without a gel pack independently of transport mode used.
