Increased sales of marine products that are traceable to the EPCIS standard

The eTrace project (eRek) is now in its second year and its results are already attracting considerable attention. The purpose of the project is to define, develop and implement a traceability system based on the EPCIS standard and to examine whether it is suitable for food traceability.

Integrating food safety information with other real-time traceability information opens up opportunities to simultaneously increase product safety. 

This spring, an experimental run was carried out in Sweden on the software that has been developed in the project, where fish tanks were marked with RFID tags as soon as they were landed. RFID tags emit radio waves, which can be easily read and the tags were glued to the outside of pots, boxes and packaging. In this way, the movement of cod from fishing, through processing and all the way to consumers could be monitored automatically. The gloves were used to obtain information on the location and timing of RFID tags, through landing and processing in Simrishavn and to consumers in Gothenburg.

The implementations that have been developed in the project are promising and our Swedish cousins appreciated the further information about the fish in graphic form. Sales increased significantly for those products where traceability information was available and store owners were very pleased to be able to show consumers the product's path from fishing to the fish table. The RFID tags used in the test run proved their worth, but so far there have often been problems with the use of RFID tags in the wet and cold conditions of fish processing.

As mentioned above, the aim of the project is to develop and implement a traceability system based on the EPCIS standard. The system replaces the fact that information is collected manually, thus increasing automation and reducing the possibility of mistakes. The Swedish Fisheries Inspectorate (Fiskeriverket), which is a participant in the project, sees great potential for the EPCIS standard and RFID tags to meet the recent EU regulation no. 1224/2009, which states that member states must demonstrate the complete traceability of fish products. Their interest is also due to the fact that they believe that the system could be useful for fisheries management.

A similar experimental run is planned for Iceland this autumn, where this technology will be used to accompany fish from fishing, through processing and all the way to consumers in Europe.

Many companies and institutions are responsible for the project and Matís oversees certain aspects of its work, but Valur Gunnlaugsson and Sveinn Margeirsson have had their way and problems with Matís' work in the project. In addition to Matís, the Norwegian companies SINTEF and TraceTracker, Lund University, the technology company Roi4u and the Swedish Fisheries Inspectorate are among the participants in the project, which is funded by the SafeFoodEra program.

The role and fate of added phosphates in salted cod products / Role and fate of added phosphate in salted fish

The aim of the project was to evaluate the fate of added phosphate in salted fish. It is clear that its amount decreases with effect and dehydration. The same goes for phosphates that are naturally present in fish muscle. Therefore, the total amount of phosphate in dehydrated products is usually lower than in fresh fish. However, it has been shown that added phosphates (di- and triphosphates) are found in both processed and dehydrated fish. However, it depends on the amount of phosphate added to the product and the salting processes used, ie. whether phosphate was added to the fish by injection or brine. Little or nothing is detected in dehydrated products if brine is used. Differences between processes can be due to the method of salting (spraying / pickling), the type and initial amount of phosphate added and the duration of action. Further research is needed to evaluate the effect of different salting processes on the fate of phosphate in salted cod muscles.

The aim of this study was to investigate the fate of added phosphates in salted cod products. The content of both added phosphates and naturally occurring phosphates, decreases during salting and rehydration. The final content in rehydrated fish (approx. 1-2.5% NaCl) is usually below values in the raw fish. However, di- and triphosphates are present both in salted and rehydrated products. The amount depends on the quantity of added phosphates in the product and on the salting procedures applied. It seems that lower contents are present in brined products than in injected products. Differences may depend on the method used for adding phosphates (injection / brining), phosphate type and, initial content of added phosphates in the muscle after pre-salting and finally on the curing time. Further studies are needed to get accurate information on the effects of different salting procedures on the fate of phosphates in salted cod products.

Development of Quality Index Method and shelf life of thawed mackerel (Scomber scombrus) / Development of Quality Index Method and storage life of thawed mackerel (Scomber scombrus)

The QIM method (Quality Index Method) is an objective, fast and reliable sensory evaluation method that has been developed to assess the freshness of fish. The aim of the study was to prepare a QIM rating scale for thawed mackerel (Scomber scombrus) stored in ice at 0 ° C and to test its use in a shelf life test. The mackerel was evaluated by sensory evaluation according to QIM and DA method (generic descriptive analysis), microorganisms (TVC and H2S producing) were also counted and histamine was measured for up to 9 days after thawing. The result of the study was the QIM method for thawed mackerel which was developed and tested in a shelf life test. Quality factor - QI (total grade) increased linearly with ice shelf life. The QIM method for thawed mackerel is based on an assessment of quality factors such as the appearance of redness, texture, color and shape of the eyes, the color and odor of the gills, the appearance of mucus in the gill and gill leaf and the intestinal dissolution, and the total fish can reach a maximum of 19. The project also developed a method (general descriptive analysis-DA) for evaluating boiled mackerel. The main characteristics of the mackerel immediately after thawing were the smell and taste of fresh oil, the smell of metal and the sweet smell / taste that faded with the storage period. What limited the shelf life were sensory properties that describe the symptoms of damage, such as the stench and taste that can be noticeable in fatty fish after prolonged cold storage. According to a sensory assessment of boiled mackerel fillets, the shelf life of thawed mackerel after five months of cold storage is about 4-6 days. The total number of micro-organisms and H2S-producing micro-organisms was lower than is usually seen at the end of the shelf-life of micro-organisms. Histamine was not detected (<5 ppm) in thawed mackerel during the 9-day ice-storage period.

The Quality Index Method (QIM) is an objective, rapid and reliable sensory method. The aim of the present study was to develop a QIM scheme for frozenthawed Atlantic mackerel (Scomber scombrus) stored in ice at 0 ° C and evaluate the scheme in a shelf life study. The mackerel was evaluated with sensory evaluation (QIM and generic descriptive analysis (DA)), microbial counts (Total viable counts (TVC) and H2S-producing bacteria) were estimated and histamine measured for up to nine days. The main result of this study vas the QIM scheme to evaluate freshness of frozen-thawed Atlantic mackerel storage in ice which was developed and tested in a shelf life study. The quality index - QI (sum of scores) increased linearly with storage time on ice. The QIM for thawed mackerel is based on the evaluation of quality parameters dealing with the appearance on back and belly side, texture, color and shape of eyes, mucus, color and odor of gills and appearance of gill filaments and dissolution of viscera. The maximum sum of scores (QI) can be 19. A method to evaluate cooked mackerel was also developed (general descriptive analysis-DA). Newly thawed mackerel had fresh oil, metallic and sweet odors and flavors. The main limitation of shelf life in chilled storage after thawing were sensory characteristics describing spoilage such as rancid odor and flavor which can be prominent in fatty fish species after extended frozen storage. According to sensory evaluation of cooked mackerel, the shelf life of thawed mackerel after five months of frozen storage is around 4-6 days. Counts of TVC and H2S producing bacteria were relatively low at the end of shelf life. Histamine was not detected (<5 ppm) in the thawed mackerel during the storage time of nine days on ice.

Matís plays a leading role in new multinational projects funded by the EU with the equivalent of ISK 860 million

Matís plays a leading role in two new and extensive multinational projects that the European Union has decided to support for three years, EcoFishMan and AMYLOMICS.

EU grants amount to a total of 5.5 million euros, equivalent to about 860 million ISK. Of this, Matís' share is a total of 950,000 euros for both projects, equivalent to about 150 million ISK. Matís manages both projects

This means that the EU transfers all funding to Matís, which then pays its domestic and foreign partners. A considerable part of the projects will be carried out at Matís 'offices in the countryside, as they are based, among other things, on Matís' good collaboration with companies all over the country. Master's and doctoral students will work on the projects.  

The European Union expects the EcoFishMan project to develop a new methodology that will be useful for changes and improvements to the Union's fisheries management system. Emphasis is placed on co-operation with fishermen, fishing and processing and on the utilization of information from electronic catch diaries. The aim of the project is to promote environmentally friendly, sustainable and economic management with a special emphasis on traceability and to minimize discards.

That EcoFishMan The project involves a total of 13 institutions, companies and universities in eight European countries, including the University of Iceland and the University of Tromsø in Norway. The project is expected to cost 3.7 million euros over three years and the EU's grant is 3.0 million euros.

  • Dr. Anna Kristín Daníelsdóttir, division manager at Matís, will be project manager and dr. Sveinn Margeirsson, Matís's division manager, will be with her on the project's science committee.

The AMYLOMICS project will utilize the diverse ecosystems of geothermal areas in Iceland to develop heat-resistant enzymes for use in the starch and sugar industries. Heat and acid resistance are essential properties in such industrial processes, but can be found in the enzymes of organisms in thermal areas.

Among the participants in AMYLOMICS is a French company Rocket Frères, which is one of the largest in Europe in the production of starch and derivatives, with an annual turnover of about 7 billion euros. Roquette Frères will be testing enzymes that will be developed in the project for testing and innovation in its production.

  • Dr. Guðmundur Óli Hreggviðsson, subject manager at Matís, will be project manager. Two other Icelandic companies, directly involved in the project, Roche Nimblegen and Prokazyme.

14 points out of 15 possible in a professional evaluation!

Sjöfn Sigurgísladóttir, CEO of Matís, says that the two projects and the EU's support for them are good news for the Icelandic scientific community and recognition for Matís:

"EU research grants are in great demand and there is a lot of competition for them. EcoFishMan received 14 points out of 15 possible in the opinion of the EU professional committee, which is a great result and returned the project to Matís and partners. With this, we become even more established in international scientific co-operation, and of course it is a special gift for Icelanders to now receive substantial funds into society from abroad during these times of recession and austerity. "

More about EcoFishMan
The European Union's Common Fisheries Policy does not deliver the desired results. Suffice it to say that close to 90% fish stocks in the jurisdiction of EU countries are overfished and a third of the stocks are in danger of extinction because they fail to regenerate. Discards are a major problem, for example it is estimated that 30-55% cod catches from the North Sea are discarded.

One of the goals of the EcoFishMan project is to analyze what has been successful in Icelandic fisheries management and "export". At the same time, there are plans for more co-operation with those who work in fishing and processing in the fishing industry.

Among the Icelandic parties that will be approached for professional knowledge are  Directorate of Fisheries, Association of Fish Processing Plants, National Association of Icelandic Fishermen, Marine Research Institute, Ministry of Fisheries and Agriculture, National Association of Small Boat Owners and several Icelandic companies that produce technical equipment for the fishing industry, such as TrackwellVaki and Marel.

More about AMYLOMICS
The biotechnology project AMYLOMICS is the idea of Matís' experts and Iceland will largely be its forum. The diversity of geothermal areas in Iceland is unique and Matís has extensive expertise in their ecosystem. The project is based on developing technology to utilize this special Icelandic genetic source, producing enzymes with certain, important properties and exploring possibilities for utilization in various areas of the chemical and food industry.

Among the participants in AMYLOMICS is the French company Rocket Frères, which is one of the largest in Europe in the production of starch and derivatives, with an annual turnover of about 7 billion euros. Roquette Frères will be testing enzymes that will be developed in the project for testing and innovation in its production.

The company Roche Nimblegen also participates in the project and will, in collaboration with Matís, develop and improve methods for obtaining genes from hot springs.

Overview

"Enhancing quality management of fresh fish with improved product management and traceability from fishing and to consumers." (Enhancing quality management of fresh fish supply chains through improved logistics and ensured traceability) is the title of the doctoral dissertation.

Dr. Ingibjörg Gunnarsdóttir, professor and vice-dean of the Faculty of Food and Nutrition, will chair the ceremony, which will take place in hall 105 at Háskólatorg and will begin at 15:00.

Opponents are Dr. Morten Sivertsvik, "Forskningsleder" at Nofima in Stavanger and Dr. Hjörleifur Einarsson, professor at the University of Akureyri.

The supervisors and the doctoral committee were the following Sigurjón Arason, associate professor at the University of Iceland and chief engineer at Matís ohf, Dr. Gunnar Stefánsson Associate Professor at the Faculty of Industrial Engineering, Mechanical Engineering and Computer Science at the University of Iceland, Dr. Sigurður G. Bogason specialist at the University of Iceland and Dr. Sveinn Margeirsson, division manager at Matís ohf.

The United Nations University School of Fisheries provided Mai Thi Tuyet Nga with a scholarship and Matís ohf. provided her research facilities. The study belonged to the projects CHILL-ON (project no. FP6-016333-2) funded by the 6th Framework Program of the European Union and Hermun kæliferla which is funded by the AVS Fisheries Research Fund, the Technology Development Fund and the University of Iceland Research Fund.  

Abstract from the study: "Strengthened quality management of fresh fish with better planning and traceability from fishing and to consumers."

The aim of the project was to: Strengthen quality management of fresh fish with better planning and improved traceability from fishing and to consumers. Part of the research was to obtain an overview of the knowledge of the directors of companies related to the fishing industry on traceability and their cost awareness in the choice of transport routes and packaging when making decisions on the choice of transport processes for marine products. Analysis of transport processes was a necessary part of the project in order to obtain a comprehensive overview of the status of the industry and the transport processes. The results of the analysis revealed which links in the supply chain could be improved in terms of shelf life, procedures, equipment, environmental impact, etc. The project investigated how temperatures evolve through the transport chain for both aviation and sea; fillet processing, pre-cooling, the effect of different packaging, - the function of storage and containers and also during the transfer of goods in the chain. The results of these components of the project were used to assess the heat load experienced by the products in the processes and used to predict shelf life. The results of the project will be used to make decisions about which processes should be improved in the supply chain so that it is most useful in optimizing the overall process. 

The advantages and disadvantages of air and sea transport for fresh fish were analyzed. The results of the temperature mapping showed a much more stable temperature in container transport by ship than by air transport. In particular, there is a risk of heat stress in air transport chains when a product is moved between different links in the refrigeration chain. Other factors in the supply chain that can affect the quality and shelf life of fresh fish are pre-cooling before packing, the location of boxes on pallets in the case of poorly temperature-controlled cooling chains and the length of the chains. 

TTI (Time Temperature Indicators) was also analyzed in the project where equipment was tested for fresh fish products and its use to assess product quality limits. TTI tests were performed in storage trials to verify that the rate of product quality change was consistent with the performance of the TTI equipment.

The doctoral dissertation is based on six scientific articles, of which one article is already published in an international scientific journal and another is approved.

Mai Thi Tuyet Nga was born on December 23, 1971 in Vietnam. She completed her B.Sc. degree from the Department of Aquatic Products Processing Technology at Kaliningrad State Technical University (KGTU), Kaliningrad, Russian Federation in 1995 and M.Sc. degree from the Faculty of Aquatic Products Processing, Nha Trang University (NTU), Nha Trang, Vietnam in 2000. Mai Thi Tuyet Nga has been a teacher of food science since 1996 at Nha Trang University (NTU). Mai Thi Tuyet Nga is married to Tran Quang Hung and they have two daughters Tran Mai Linh and Tran Mai Khanh Huyen.

New project - Utilization of slag from fish processing

The main goal of the project is to utilize in a profitable way the catch that comes ashore in Þorlákshöfn with catch that is not gutted at sea.

The project manager for the project is Þorbjörn Jónsson at Atvinnuþróunarfélag Suðurlands and the partners are: Matís ehf., Auðbjörg ehf, Atlantshumar ehf., Hafnarnes Ver hf., Frostfiskur ehf., Lýsi hf., Landgræðsla ríkisins, Búnaðarsamband Suðurlands and
MS Selfoss.

The project is funded by the AVS Fisheries Research Fund.

The aim is to establish a start-up company at the end of the project and the company will focus on the utilization of the slag for fertilizer production. The expected by-product of the production process is crude oil

The use of sludge for fertilizer has a long history around the world. In Iceland, it was common in the first half of the last century to plow fields. Slug is suitable as an organic fertilizer for both vegetables and other plants and grasses. Studies have shown that the nitrogen content of fish slag is better utilized than nitrogen from synthetic fertilizers, as a large part is lost by evaporation. The slag has a much longer activity in fertilizer value as the elements are in organic form and are released more slowly into the soil.
