Announcement from Matís ohf.

Matís ohf received an announcement yesterday from its webmaster, Hugsmiðjan hf., That unscrupulous foreign parties had broken into the company's website. The purpose was to use the webmail server to send questionable messages to unsuspecting recipients. It is not known how many messages were sent in this way in the name of Matís, nor whether the recipients are in Iceland or abroad. Hugsmiðjan, however, quickly managed to block this illegal activity and immediately switched off the Matísvefs mail server.

On this occasion, Matís would like to apologize if any of the company's customers in Iceland have received unwelcome e-mails where the sender is registered at matis@matis.is, even with messy content. Matís regrets this but also hopes that the person in question has realized what was going on, as the content of the shipments is far from everything that Matís stands for.

Measures have been taken in collaboration with Hugsmiðjan to prevent this from happening again, and Matís would like to thank its responsive web hosting company for their quick handling.

NORÐURKVÍ - a new research project at Matís

Farming equipment, especially sea cages, has suffered extensive damage due to difficult environmental conditions in Iceland. In this light, the NORÐURKVÍ project is launched with the aim of designing and constructing sea docks that meet the strictest requirements for strength and durability for Icelandic conditions.

The project, which is carried out in collaboration with the Westfjords Nature Center, SINTEF Fisheries and Aquaculture, the Marine Research Institute, the Icelandic Meteorological Office and Hraðfrystihúsið Gunnvöra, will be guided by the following issues:

  1. Data on special Icelandic environmental conditions will be compiled
    which must be taken into account when designing sea cages for Icelandic conditions.
  2. Examine whether dock solutions currently on the market are suitable for environmental conditions in Iceland.
  3. Develop, if necessary, existing dock solutions to the current situation.
  4. Test the solutions found in the project under real conditions in Iceland with regard to their impact on the fish that are farmed in them and how they are suitable as a workplace.

This is an ongoing study that will yield results that will be useful to all parties involved in seaweed farming in Iceland.

Project manager is Jón Árnason.

The fast food at Höfn is lobster soup!

The fast food restaurant Kokkur in Höfn in Hornafjörður has started selling lobster soup through a carport. This is a gourmet lobster soup made from local ingredients. The Chef's Lobster Soup is the result of a collaboration with Matís, and the Chef has, among other things, been assisted by food designers and food scientists who work on behalf of Matís to make the idea of selling lobster soup through a car hatch a reality.

Experience
It is undeniably a special and powerful experience to buy such an impressive product as a gourmet lobster soup in a carport at a fast food place. To add to the excitement, the soup is served in a beautiful recyclable packaging and comes with a napkin that refers to the only true red checkered picnic tablecloth. A wooden spear with freshly grilled lobster is included with the soup.


Premium ingredients
The Lobster Soup brand is a coat of arms, which refers to the quality of the product and the fact that it is from the lobster capital of Iceland. The soup contains only premium ingredients, but the base is of course horned lobster.
Slow cooking - The key to making lobster soup is nutrition. No less than a full working day goes into the lobster soup making where the only true lobster flavor is conjured up with a right boil for a long time under the strict supervision of skilled chefs.

 
Food culture
The Chef's Lobster Soup is a unique high-quality fast food that has a strong reference to its origins and environment, but is at the same time an international delicacy. The product seeks to promote the strong lobster tradition of the area. In this way, you can experience a gourmet soup that would be worthy of any restaurant, in a quick, cheap and innovative way.


The collaboration between Matís and the Chef
The Chef's Lobster Soup is the result of a collaboration with Matís, which sells comprehensive consulting and access to product development facilities to transform ideas into quality food. The chef has, among other things, been assisted by food designers and food scientists working for Matís to make the idea of selling lobster soup through a car hatch a reality. 

 
History of the Chef
The brothers Jón Sölvi and Valgeir, opened the fast food restaurant Kokkur in style in November 2007, where all products are processed through a car hatch. It can be said that the term "fast food" has taken on a new and inspired meaning, but Jón Sölvi is an experienced artisan chef who had until then worked at the finest restaurants in the country. Opening a small place like Kokkur perfectly describes Jón's mentality. It is not the size but the quality and originality that matters in his mind.

Matís and Veiðimálastofnun in collaboration: research on the genetics of Icelandic salmonids

Matís Ohf and Veiðimálastofnun signed a framework agreement yesterday, Thursday 3 July, on strengthening co-operation between the companies. Einar K. Guðfinnsson, Minister of Fisheries and Agriculture, confirmed the agreement on that occasion. The signing took place in the premises of Matís-Prokaria, Matís' biotechnology department, at Gylfaflöt 5 in Grafarvogur. The collaboration between Matís and Veiðimálastofnun will be mainly in the field of genetic research and aquaculture.

Matís – Prokaria showed on the same occasion a new sequencing machine, but the device can sequence large amounts of genetic material, for example for stem genetic analysis and in the search for interesting genes for new enzymes that can be used in the pharmaceutical, food and energy industries.

The collaboration has already begun and an extensive study is underway on the stock variability of Icelandic salmon and their movements in the sea around Iceland. This is part of an international research project on Atlantic salmon. Preliminary results indicate a large variability in salmon stocks in the rivers around the country. The goal of scientists is to be able to answer various questions by being able to trace the origin of salmon in the Atlantic Ocean to the year of origin or river system. This is a very ambitious goal as each country needs to do a lot of work both in sample collection and genetic analysis. Icelanders seem to have come a long way with work in this field and the aim is now to take the next step in the research related to sea salmon. The aim is to co-operate with the fishing fleet to collect samples from salmon that enter the vessels' fishing catch.

Most stocks of Atlantic salmon have declined sharply and are widely on the endangered species list. Very little is known about salmon seafaring and research has been based on traditional markings and research on ships at sea. In addition, research with electronic signals has recently begun in Iceland. This research that is currently being presented provides a stronger foundation for people's knowledge in this field. The collaboration between the companies will increase knowledge of the genetics and ecology of salmonids. This knowledge is then used in further research on the utilization and protection of the institutions for the benefit of the country and the nation.

Veiðimálastofnun has conducted stock genetic research on freshwater fish and Matís has conducted research and utilization of nature's genetic resources and has built up extensive knowledge and skills in genetic analysis of all kinds of organisms from the environment. Veiðimálastofnun and Matís will work closely together on research. These studies cover basic and practical research in natural and genetic sciences with a special emphasis on the stock genetics of salmon, trout and char. Such research is useful in fisheries management and in the development of fish farming and aquaculture.

Matís ohf is a public limited company owned by the state, which aims to strengthen international competitiveness and the development of Icelandic food production, promote the hygiene and safety of food and support the scientific activities of university institutions, innovation and start-ups, as well as fulfilling social obligations to individual industries.
 
Veiðimálastofnun is a research and service institution. The role of the Directorate of Fisheries is to study ecosystems in rivers and lakes, study fish stocks in freshwater, provide advice on fishing utilization and on the ecosystem and environment of rivers and lakes, for example in connection with construction, and maintain a database on natural habitats in freshwater.

Chemical composition and properties of saithe isolate

Iceprotein ehf produces protein from raw fish wood with acid and alkali treatment. This process results in two layers: the upper layer is a protein isolate and the lower layer is a liquid phase. The liquid phase contains proteins that have not been used so far but have potential as food ingredients and as dietary supplements. Saithe proteins have a good chance of being a substance in health food if they are treated correctly. This could increase the value of saithe as it is a cheap and underutilized fish species. The purpose of this experiment was to investigate the possibility of utilization of the lower layer from acid and alkali treatment from saithe. The composition and properties of this substance were identified and its potential as a health food ingredient was concluded. Saithe was treated with acid and alkali and the lower layer was collected. The liquid phase was microfiltered and the protein mass was washed. Analysis of the chemical composition of the raw material, electrophoresis (SDS-PAGE), lyophilization, examination of the relationship between protein solubility and acidity and measurement of ACE inhibitory activity were performed. The results show that the material was about 95% water, 4% protein, 0.16% fat and 0.5% minerals. The proteins were insoluble in water, mostly myosin and actin and were not measured by ACE inhibitory activity. Future plans are to hydrolyze the proteins with enzyme technology to make them soluble and bioactive. Experiments will also be made with the addition of antioxidants to the material before and after enzyme treatment to prevent the oxidation of fats that otherwise degrade the taste quality.

Iceprotein ehf processes proteins from fish raw material with a pH-shift method. The pH-shift method results in two phases: the upper layer being the protein isolate and the lower layer a liquid phase containing insoluble proteins. These insoluble proteins have not been utilized so far but are potential food ingredients or nutritional supplements. If handled in the right manner, saithe proteins have good potential as ingredients in health foods. This way it would be possible to increase the commercial value of saithe which is an underutilized and inexpensive fish species. The purpose of this investigation was to explore the possibilities of utilizing the lower layer from saithe processed with the pH-shift method. The chemical composition and functional properties of the proteins in the lower layer were analyzed and their potential as health food ingredients explored. Saithe was processed with the pH-shift method and the lower layer was collected. The liquid phase was filtered and the protein mass was washed. The chemical composition was determined, the samples were subjected to electrophoresis (SDS-PAGE), freeze-dried, the relationship between solubility of the protein and pH was investigated, and the ACE-inhibiting function was measured. The results demonstrated that the material was 95% water, 4% protein, 0.16% fat and 0.5% minerals. The proteins were insoluble in water and consisted mostly of myosin and actin and did not show ACE-inhibiting activity. The future plan is to hydrolyze the material using enzyme technology to make them soluble and bioactive. Experiments in which antioxidants are added to the material will also be performed before and after enzyme treatment to prevent lipid oxidation which can have a negative effect on the product.

Undesirable substances in seafood products– results from the monitoring activities in 2006

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 of 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 assessments and to influence the setting of maximum levels for undesirable substances, for example in Europe. 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 2006. It is a long-term goal to assess the condition of Icelandic seafood in terms of the amount of undesirable substances. This goal can only be achieved through continuous monitoring for a long time. Each year, the monitoring is aimed at adding the most needed data and thus making the database more accurate and comprehensive with each passing year. in marine products intended for human consumption and in fishery and flour products.

This project was started in 2003 at the request of the Icelandic Ministry of Fisheries. 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 the setting of maximum values that are now under consideration within the EU. This report summarizes the results obtained in 2006 for the monitoring of various undesirable substances in the edible part of marine catches, fish meal and fish oil for feed. This project began in 2003 and has now been carried out for four consecutive years. One of the goals of this annual monitoring program of various undesirable substances in seafood is to gather information on the status Icelandic seafood products in terms of undesirable substances, this is a long-term goal which can be reached through continuous monitoring by filling in the gaps of data available over many years. For this reason, we carefully select which undesirable substances are measured in the various seafood samples each year with the aim to eventually fill in the gaps in the available data over couple of year time. The results obtained in 2003, 2004 and 2005 have already been published and are accessible at the Matis website (IFL Report 06-04, IFL Report 33-05 and IFL Report 22-06, respectively). In 2006, data were collected on, polychlorinated dibenzodioxins and dibenzofurans (17 substances), dioxin-like PCBs (12 substances), marker PCBs (7 substances), 10 different types of pesticides, polybrominated flame retardants PBDE as well as trace elements and heavy metals.

Fat tolerance of cod

The purpose of this study was to investigate the effect of fat content in feed on the growth and cleaning of cod of different sizes. Knowledge of the nutritional needs of fish is a necessary prerequisite for the preparation of feed for them. Two-size cod (120 g and 600 g) were fed (in triplicate) for 12 weeks on feed containing 10.0%, 13.5%, 21.2%, 24.5% and 27.7% fats in dry matter. Different fat content did not affect growth (SGR), body mass index (CF), fillet utilization, liver fat content or fillet fat content. In the smaller fish, the feed index (FCR) decreased with increased fat in the feed. The feed fat did not affect the fat content of offal without liver in the smaller fish (120g) but in 600 g fish the fat in the intestines increased with increased fat content of the feed. The fat content did not affect the proportion of gutted weight of the total weight in the 600 g fish, but in the smaller fish the proportion decreased with increased fat in the feed. Liver ratio (HSI) in 600g fish was not dependent on the fat content of the feed, but there was a positive correlation between feed fat and HSI in the 120 g fish. This means that the fat tolerance of cod in terms of liver ratio depends on the size of the fish.

Detailed knowledge of the nutritional requirements of fish is essential for feed formulation. The aim of this research was to investigate the effects of different lipid content in diets for Atlantic cod of different size. Cod of two size groups (initial weight 120 grams and 600 grams) were fed, in triplicate, for 12 weeks diets containing 10.0%, 13.5%, 21.2%, 24.5% and 27.7% lipid in dry matter. Different lipid content in the diet did not affect growth (SGR), condition factor (CF), fillet yield, lipid content in liver or lipid content in fillet. In the smaller fish, FCR was reduced with increased diet lipid. The lipid content in the diet did not affect the lipid content of intestines in the 120 grams fish but in the 600 grams fish there was a positive correlation between lipid content in diet and intestines. Dietary lipid did not affect gutted weight (calculated as the percentage of round weight) in the 600 grams fish but in the 120 grams fish, the percent gutted weight decreased with lipid content of the diet. The Heposomatic index (HSI) in the 600 gram fish was not affected by the lipid content of the diet but dietary lipid content significantly affected the HSI in the smaller fish. This indicates that the lipid tolerance of Atlantic cod, with respect to the effect on HSI, is size dependent.

HEALTH DIET: A summary of the main categories of health foods and scientific evidence of their effectiveness

Foods that are considered to be able to improve human health can be classified as health foods such as unchanged organically grown foods, dietary supplements and target foods. In the first part of this dissertation, definitions and regulations are reviewed, the material and function of popular health products and permitted health claims are discussed. According to regulations, food supplements are foods that are intended as a supplement to a regular diet, but targeted foods are often defined as foods that have been modified in order to increase their health effects. The second part of the dissertation deals specifically with proteins in health products with an emphasis on the bioactivity of peptides. Bioactive peptides have a beneficial effect on health beyond normal nutritional value. They can have physiological effects on the activity of the gastrointestinal tract, cardiovascular system, immune system and nervous system. The effects of peptides in these systems are reviewed. The potential of fish muscle protein in the healthcare product market is being considered. Nowadays, a very large amount of underutilized by-products from seafood, and research has therefore focused a lot on finding ways to utilize and increase their value. The target food market is booming at the moment and is forecast to expand. Seafood has a positive health image among consumers and therefore health products that contain fish muscle protein could have an impact. However, it requires the right taste, texture and bioactivity to be delivered to the consumer, in addition to which the products need to be introduced to the products in a targeted and powerful way.

Food that has the potential of improving health can be categorized as health food eg organic food, dietary supplements and functional food. Definitions, regulations, composition and functionality of popular health food and permitted health statements, are discussed. According to regulation dietary supplements are foods that are intended as an addition to a normal diet, however functional food is commonly referred to as food that has been fortified to enhance its positive effects on health. The latter part of this paper discusses proteins in health foods with emphasis on bioactive peptides. Bioactive peptides have a positive effect beyond their regular nutritional value. They have been shown to have a biological effect in the alimentary canal, the heart and the vascular system, the immune system and the nervous system. The mechanisms involved are reviewed. The potential of fish protein in the functional food market will also be addressed. Today, great quantity of marine by-products are underutilized. Therefore, emphasis has been within the research community on finding methods to utilize and enhance their value. Currently the functional food market is blooming and is expected to grow in the following years. Marine products have a positive health image among consumers, thus health products containing fish proteins could be a great success. To be realized, this requires that the right taste, texture and bioactivity is delivered to the consumer accompanied by a good advertisement campaign.

Matís ohf's Chemistry Research Department offers interested students in chemistry or biochemistry a scholarship for a master's degree (MSc) in the field of trace chemical analysis
The title of the project is Analysis of toxic and non-hazardous chemical forms of arsenic in fishmeal by HPLC-ICP-MS

A brief description of the project
There is a lot of arsenic in the ecosystem in organic compounds as well as in inorganic form and more than 50 natural chemical forms of arsenic have been found. Seafood naturally contains a high concentration of the total arsenic compared to, for example, agricultural products. Most arsenic in seafood, on the other hand, is bound in an organic form called arsenobetanide, which is completely safe for humans and animals. As in agricultural products, other forms of arsenic are found in marine products, such as inorganic arsenic (arsenite and arsenate), methylene-arsenic compounds (mono, di, tri and tetra), which are highly toxic and thus dangerous to human health.

The morphology of arsenic in seafood is important because the bioavailability and toxicity of arsenic are highly dependent on its chemical form. Nevertheless, current regulations on the content limits of arsenic in food and feed only take into account the total arsenic in food / feed components and do not take into account the toxic chemical form of arsenic. Research into the chemical forms of arsenic and the transformations of these substances is important for understanding the danger to us posed by arsenic in seafood.

Objectives
The aim of this research project is to develop chemical analysis methods that can detect both toxic and harmless chemical forms of arsenic in fishmeal and not just the total amount of arsenic as is done today. HPLC-ICP-MS chemical analysis equipment will be used to analyze new and known arsenic forms in fishmeal.

This project recently received a grant from the AVS research fund and will be carried out in collaboration with Síldarvinnslan hf. and Vinnslustöðin hf, in addition to which other fishmeal producers are involved in the project.

Location
Matís & HÍ. There is also a possibility that part of the study will take place at foreign universities and research institutes with which Matís collaborates.

Matís' supervisor is Dr. Sasan Rabieh, who is an expert in this field and leads the development of this new research area at Matís. This structure includes support for students for master's studies in this field. Possibility is
Part of the study should take place at foreign universities and research institutes.
