The export routes of fresh fish products have largely depended on their shelf life. A large part of the products have been exported by air to minimize transport time from producer to consumer, but due to economic and environmental considerations, manufacturers have increasingly focused on shipping in recent years. 

It is therefore important to look for ways to extend the shelf life of fresh products, for example by improving packaging and improving temperature control throughout the process from fishing to consumers. But it is more than the direct cost of transportation and the growing environmental awareness in the world that plays into the competition of shipping and air transport. The results of the AVS projects Simulation of cooling processes and Integration of cooling research have indicated a clear difference in the stability of temperature control in shipping and air transport, in favor of the aforementioned mode of transport. The study is also part of the EU project Chill-on (FP6-016333-2).

In the current experiment, a precise comparison is made between the temperature fluctuations that products experience during transport from Dalvík to Bremerhaven, with flights on the one hand and ships on the other. The temperature and humidity through the transport chain are mapped with 24 - 29 sirens outside and inside the boxes of each shipment, thus obtaining a comprehensive picture of the heat load that the packaging must be able to protect against this valuable product. At the same time, changes in quality are assessed. The transport costs and shelf life of products will be assessed and the results used to obtain indications of the advantages and disadvantages of each mode of transport.

An interesting post can now be found on the website of Ríki Vatnajökull, www.rikivatnajokuls.is. The article discusses, among other things, how income can be increased by further linking tourism to basic industries.

Matís is working on studies of the effects of pre-cooling products before packaging with regard to the shelf life of products. The closer the product is to the optimum temperature during packing, the smaller the need for refrigeration in the actual transport process.

It is very important to lower the temperature of the product in small units before packing, otherwise there is a risk of slow and uneven cooling, as is the case with large packed units. The pre-cooling methods used in the experiments are liquid cooling and skin cooling, and the products are packed in a foam plastic box after trimming and cutting into nape pieces. The boxes are stored in temperature-controlled conditions where the actual transport processes are simulated. Changes in quality and damage processes are monitored at regular intervals. The results will then be used to assess the shelf life of products that have been packaged after or without precooling.

These pre-cooling experiments are useful for two AVS projects, i.e. Integration of refrigeration research (R 061-06) and Simulation of refrigeration processes (R 037-08) and are also part of the EU project Chill-on (FP6- 016333-2). In the first project, they are used for more purposeful process management and the publication of guidelines for the industry. In Simulation of cooling processes, more emphasis is placed on the transport processes and the connection between pre-cooling and the design and use of packaging in transport processes. The results of the pre - cooling experiments are useful in the development of heat transfer models for fresh fish in transport, which are used to improve transport processes.

Well over four hundred foreign students applied to attend courses in Iceland!

From March 10 to 18, an international course will be held in Iceland under the auspices of BEST in Iceland. BEST (Board of European Students of Technology) is a European association of university students in technology.

A total of 81 European universities in 30 countries are members of the association, but an Icelandic member association was founded by students at the University of Iceland in 2005. The main purpose of BEST is to offer students at member universities additional education in the form of short courses as well as giving students the opportunity to learn languages of other nations.

The course that will be held in Iceland next week is entitled “Eat that! Innovation in food technology and nutrition "and is run by BEST in close collaboration with Matís (www.matis.is) and the University of Iceland, in addition to which Reykjavík University, Landspítali University Hospital, Marel and Lýsi are involved in the project.

The course will cover "nutrition in innovation" from A to Z. During the week-long stay, the European students will listen to lectures by professors at the University of Iceland, Matís employees and working engineers, visit Icelandic companies and visit field guards. The students will also visit Gullfoss and Geysir and Jökulsárlón, among other places.

It should be noted that the students who found out in this course only have to pay for part of the fare to and from the country, but a grant was received from Europe in Youth for all other costs of the course for each participant.

There was great interest in the course, with a total of four hundred European university students applying. As the number of participants was limited, only 22 came to Iceland on this occasion. The number of applications shows that there is a great deal of interest among educated European young people to learn from Icelanders about food and nutrition as well as to get to know a country and a nation.

Please contact the President of BEST in Iceland for further information and interviews.

A new report has been published by Matís. The report is a summary of previous research on capelin roe.

In recent years and decades, various measurements and research on capelin roe in Iceland have been carried out at Matís ohf / Rannsóknastofnun fiskiðnaðarins. This is primarily a study of microorganisms, egg filling and water content. The report will cover microbial research carried out during the 1984 season, microbiological measurements in the period 2000-2008 and measurements of water content and egg filling 1984-2008.

The information that can be found there is exciting and relevant these days, as people are talking about the importance of capelin for the country's economy.

The full report can be found here.

For further information, please contact Margeir Gissurarson, margeir.gissurarson@matis.is.

Matís' employee, Hrönn Ólína Jörundsdóttir, defended her doctoral dissertation "Temporal and spatial trends of organohalogens in guillemot (Uria algae) in North Western Europe" on February 6, 2009 at Umildfild Stockholm University.

The dissertation deals extensively with persistent organic pollutants in the Nordic countries, such as PCBs and the insecticide DDT, as well as their metabolites, which were mainly measured in long-range eggs. The substances were measured in eggs from Iceland, the Faroe Islands, Norway and Sweden to obtain a geographical comparison.

The results show that the North Atlantic ecosystem is less polluted than the Baltic ecosystem, but various pollutants were found to be in similar concentrations in these areas and it is necessary to investigate further why this is the case. Fluorinated alkanes, which come from outdoor clothing, have recently been found in significant amounts in nature, measured in long-tailed eggs from Iceland, the Faroe Islands, Norway and Sweden and were in some cases in higher concentrations in eggs from the North Atlantic than in the Baltic Sea. Brominated fire retardants, which are used in electronics, among other things, were measurable everywhere and it seems that it is possible to identify the different origins of the substances that reach the North Atlantic, on the one hand from North America and on the other from Europe.

A comparison was also made of the amount of pollutants in seven Icelandic bird species, i.e. heron, eider, osprey, elephant, herring gull, black-backed gull and skimmer. The foam was found to have a significant high concentration of pollutants, including PCB compounds and the insecticide DDT, and it is important to study the health condition of the foam.

It is clear that part of the pollution measured in the Icelandic ecosystem travels through ocean and air currents to Iceland, but on the other hand a significant part is due to Icelanders' use of goods that contain various pollutants.

Supervisors were dr. Åke Bergman Professor of Environmental Chemistry at Stockholm University, dr. Professor Anders Bignert, Swedish Museum of Natural History and dr. Mats Olsson Professor Emeritus. The opponent was Dr. Derek Muir, Environment Canada.

The examination committee consisted of dr. Kristín Ólafsdóttir, Associate Professor at the University of Iceland, dr. Björn Brunström, professor at Uppsala University and dr. Conny Östman, Associate Professor at Stockholm University.

Future Days 2009 will be held on Friday 20 February in the premises of Háskólabíós.

Due to enormous changes in the Icelandic economy and economic situation, a record participation among students can be expected this year. Framadagar is therefore an ideal platform for companies to reach the future workforce of the nation by introducing themselves and their activities and thus gain a certain advantage over the competitive parties in the race for the most qualified staff.

More information can be found at www.framadagar.is and with Jón Haukur Arnarson, jon.h.arnarson@matis.is or Steinar B. Aðalbjörnsson, steinar.b.adalbjornsson@matis.is.

The project was funded by the Student Innovation Fund in the summer of 2008 and was carried out by Hugrún Lísa Heimisdóttir, a student who had completed her first year in biotechnology in the field of resources at the University of Akureyri. The student's project was part of a larger project, “Bætibakteríur í lúðueldi”, which was carried out in collaboration with Matís ohf., The University of Akureyri, Fiskey hf and the University of Hólar with a grant from the Technology Development Fund (2006-2008).

The aim of the project as a whole was to look for possible beneficial bacteria in the halibut farming of Fiskey hf. and which could then be added to the environment of halibut larvae for the purpose of improving the growth and performance of the larvae.

The first few weeks are the main bottleneck in halibut farming and other marine fish, but then the larvae feed on live feed animals. The forage animals carry a large number of bacteria and the larvae at this stage of development need to rely solely on a non-specific immune response. There is therefore great interest in the use of supplementary bacteria in the aim of controlling the composition of bacterial flora in the environment and gastrointestinal tract of larvae and making it more positive for the larvae.

Treatment with a mixture of three types of potential beneficial bacteria turned out to give significantly better results to halibut larvae in the early stages of rearing, and in the student's project the focus was therefore on the other side of the beneficial bacteria, ie. the aspect of the bacterial properties that can be studied and measured in the laboratory. One of the characteristics of powerful supplemental bacteria is to inhibit the growth of unwanted bacteria and the student researched this and various other properties of the bacteria. It is also important to look for cost-effective ways to produce the bacteria in large quantities and store and transport them without losing their properties. Freeze-drying is a convenient and desirable way to store and transport bacteria, and the student examined the growth of the bacteria and their growth-inhibiting effect in both fresh and freeze-dried cultures.

The main results of the project showed that the supplementary bacteria had an inhibitory effect on the growth of dominant bacteria in some samples but little or no effect on the growth of dominant bacteria in other samples. This could indicate that in some larvae the bacterial flora is rich, which has gained a good foothold there and therefore it is difficult to influence the growth of the bacteria. Therefore, it is important to treat with supplemental bacteria early in the breeding process in order for the desired bacteria to gain a foothold there. The results also indicated that the three bacterial strains grow better in the presence of each other than alone.

It can therefore be said that the student's project has shed clear light on the properties of the additive bacteria and the most suitable methods of their production for use in the early stages of halibut farming.

The project was carried out under the guidance of Rannveig Björnsdóttir, lecturer at the University of Akureyri and other experts at Matís ohf. in Akureyri. For further information, contact Rannveig at 422-5108.
