There is great interest among the fishing industry in Matís' experiments with daymarks

In recent months, Matís has been responsible for experiments with logos on board fishing vessels to increase traceability and information flow within the value chain of marine products. 

Several types of tags have been tried, as well as the amount of information that appears on the tags and their utilization after the catch comes ashore. There is a growing interest among shipping companies to use data such as this, as all parties in the value chain are becoming much more aware than before of the values inherent in information and traceability.

Matís employee defends his master's thesis today

Aðalbjörg Birna Guttormsdóttir, master's student in environmental science at the University of Iceland will today, at 15:15 in room V-157 in VR2, defend their master's thesis in environmental and resource science. The master's thesis bears the name Life Cycle Assessment on Icelandic cod product based on two different fishing methods.

Aðalbjörg's project is carried out in collaboration with Matís, the Faculty of Engineering at the University of Iceland and the fisheries companies Vísir hf and Fisk Seafood hf. The excerpt from the dissertation states, among other things:

Life cycle analysis (LCA) enables us to get a complete picture of the life cycle of a product or service. In this MS project, 1 kg of lightly salted loose-frozen cod fillets with red and bone caught with bottom trawls on the one hand and on the line on the other are compared. Information was collected from two Icelandic fisheries companies, FISK Seafood, which owned and operated the trawler Hegranes SK and Vísi hf, which owns and operates the liner Kristín ÞH. Data were collected from the processing sites of both companies, FISK Seafood in Sauðárkrókur and Vísir hf in Þingeyri. The product was then transported from processing through transport to Seville in Spain where the product is sold. The main results are that cod caught in bottom trawls have a significantly greater environmental impact within all the environmental factors that were taken into account. The greatest environmental impact is to be found in the fisheries themselves, which is due to the vessels' use of oil. To catch 1 kg of the finished product, the fishing vessel with the bottom trawl burns 1.1 liters of oil while a liner uses 0.36 liters. There is also a significant environmental impact within the cold stores, as the processing takes place mainly due to the refrigerants used there. The transport of the product is also a major factor in the environmental impact, as the product is transported by refrigerated long distances and transported by sea in refrigerated containers to Europe with the associated environmental impact. So-called soot traces were calculated, which indicate greenhouse gas emissions converted into carbon dioxide equivalents. The footprint of 1 kg of cod caught by bottom trawl is 5.14 kg of carbon dioxide equivalent, while the footprint of the same amount of longline cod is 1.58 kg of carbon dioxide equivalent.

Mercury in trout from Þingvallavatn

Matís and the research company Laxfiskar held a meeting to present the results of a joint study of the amount of mercury in trout from Þingvallavatn. 

The study was based on human nutrition and was carried out to draw a picture of the amount of mercury in Þingvallaurrið, taking into account their size and prehistory. The meeting was held on Wednesday, 27 May 2009, at 14:00 in Sjávarútvegshúsið, Skúlagata 4, on the 1st floor.

The results of the study show that mercury is measurable in Þingvellir trout. Mercury can be very toxic, especially for brain development. The maximum level of mercury in salmonids according to Icelandic and European regulations is 0.5 mg / kg. Foods that exceed the maximum levels set in Icelandic regulations may not be distributed or sold because such foods may be harmful to the health of consumers. The amount of mercury in Þingvallaurrið is in the range of 0.02 - 1.02 mg / kg. The results of the study showed that there is a strong correlation between the length of Þingvellir trout and the amount of mercury. Trout longer than 60 cm are very likely to contain mercury in quantities exceeding the permissible limits. The smaller trout is on average below the permitted limits and is therefore safe to consume. It is recommended that trout that are longer than 60 cm are not used for food but that they are released back into the water as they are important for the growth and development of the trout stock in Þingvallavatn. The results showed that the mercury pollution was found in comparable amounts in trout all over Þingvallavatn. However, evidence was found that mercury pollution may be higher in one area. It is therefore considered desirable to carry out further research to investigate possible regional differences in the concentration of mercury in the vicinity of Þingvallavatn.

Regarding the risk of consumers consuming foods with higher mercury concentrations, it is worth noting that it is especially important that individuals in certain risk groups, such as pregnant women and women who are breastfeeding, avoid such foods.

The study was funded by Orkuveita Reykjavíkur's Environment and Energy Research Fund (UOOR).

New production method for marrow mixture for injection into fish products

The main problems with the use of marlin in fillets have been related to its stability and other quality factors. With improved marrow properties and stability for injection, it is a more promising option as a raw material in various products leading to its added value.  

This involves both improved utilization of by-products and improved utilization of products. When injecting into fillets, the marlin has become part of a more expensive product and the export value is therefore more compared to the export value of the marlin.

The aim of the project "Membrane blasting" was to develop a new production method for a blending mixture for injection into fish products based on leveling (membrane blasting), but the project is now complete. The process developed is successful in terms of stability, water resistance, appearance and sprayability of the mixture. The effects on micro-organisms varied according to the raw materials and processes used, but they were not noticeable in all cases. If the pressure is sufficient, however, the number of microorganisms can be reduced. The benefits of injecting fish products lie in the increased utilization and quality of injected products that can yield significant benefits at minimal cost. Injected products were more sensitive to freezing than cooling in terms of weight loss after injection. However, the risk with chilled products is always that the shelf life is reduced as microorganisms spread easily around the muscle by injection.  

The benefit of this production method is not only the increased utilization of fish products for injection. The value of the marlin also increases significantly just by becoming part of a more valuable product such as fillets or fillet pieces.

The project was funded by AVS and Tækniþróunarsjóður. Partners were Matís ohf, Síldarvinnslan hf and Iceprotein hf.

Article by Matís employees in Food Chemistry

An article was recently published in the peer-reviewed journal Food Chemistry on the antioxidant activity of Icelandic seaweed (Tao Wang, Rósa Jónsdóttir, Guðrún Ólafsdóttir. 2009. Total phenolic compounds, radical scavenging and metal chelation of extracts from Icelandic seaweeds. Food chemistry, 116, 240-248).

These are results from the project Gold in Aegir's fists (Novel antioxidants from Icelandic marine sources) sponsored by the AVS fund.

Algae contain polyphenols that have high bioactivity, including antioxidant activity. Two years ago, many algae species were collected, the total amount of polyphenols was determined, and their antioxidant activity was assessed by several antioxidant assays. The brown algae, seaweed, seaweed, seaweed, seaweed, seaweed and algae were collected, as well as salsa and seaweed, which are red algae, and marijuana, which is green algae. It was found that the highest levels of polyphenols were found in the brown algae, especially in the seaweed, and there was a strong correlation between the levels of polyphenols and the antioxidant activity of the algae. Preliminary evidence also shows that seaweed has an antihypertensive effect (ACE inhibitory activity), but this needs to be examined further.

Based on these results, it was decided to collect more seaweed and saliva and research further. The next article from the project is ready for publication, but it only deals with salts and the isolation of anti-corrosion substances from them.

The Arctic Tilapia project that has been worked on at Matís is funded by the Technology Development Fund and the goal of the project is to develop products that make tilapia whitefish fish in a closed farm that uses cooling water from a large steam power plant economically in Iceland. Ragnar Jóhannsson division manager at Matís ohf. runs the company Arctic Tilapia together with others and their goal is to grow tilapia fish in Iceland. In order for this to happen, product marketing channels must be in place and secure. It is not possible to compete in frozen fish markets because competition from East Asia is too fierce. A prerequisite for cost-effectiveness is to sell the fish in valuable markets in Europe, such as the market for fresh fillets, but in order to do so, the fillets must be transported by sea and certain associated freshness problems must be solved. The future vision is that low heat from the steam power plants can be used to produce large quantities of fillets for valuable markets.

The project “Microbiology and Spoilage Trail in Nile perch ( Lates niloticus) "Lake Victoria, Tanzania" was worked on at the Fisheries Inspectorate's laboratory in Tanzania and at Matís. The project was funded by the United Nations Fisheries University (UNU) and by the National Fish Quality Control Laboratory (NFQCL) -Nyegezi "in Tanzania.

The main objectives of the project were to study the natural microflora of Nile perch and the shelf life of raw fish and processed fish fillets under ideal laboratory conditions and under normal processing conditions in four fish processing companies on Lake Victoria in Tanzania.

Nile perch is a very important commercial fish for the countries that have fishing rights in Lake Victoria and is important for the export income of these countries. The fish is mostly exported in fresh or frozen fillets. Most exports are to EU countries and fresh fillets are exported by air. As limited studies have been performed on the microbial condition and shelf life of Nile perch, the aim of the study was to obtain basic information on the microbiological factors that most affect the shelf life. Specific culture methods were used to investigate which microbial groups had the greatest effect on the spoilage process, in addition to which certain chemical measurements and sensory assessments were used to assess the freshness of the product. The results can then be important in evaluating the success of new processing and transport methods in the production and distribution of Nile perch.
