An introductory meeting was held today in the project Cycle Economy of Meat Production. This is an exciting collaborative project between Matís and Kjarnafæði / Norðlenska that deals with the utilization of by-products from meat production.
The meeting of course took into account the current disease control rules and took place through teleconferencing equipment, as can be seen in the attached picture.
The aim of the project is to improve the production and handling of raw materials by identifying opportunities for the utilization of by-products from slaughter. Based on the results of an analysis that has already taken place on by-products at Kjarnafæði / Norðlenska, it is proposed to study two main options in the project; on the one hand, to investigate the possibility of utilization and processing of animal blood and, on the other hand, the utilization of general slaughter waste as a raw material for pet food production. A life cycle analysis will also be performed on current processes and the new processes that will be analyzed. The novelty of the project is the use of known solutions to improve domestic utilization and production and to develop products that are new in Iceland.
The recognized protective genotype against scrapie in sheep, ARR, has now been found for the first time in an Icelandic sheep. This is a great meeting because this is a genotype that is internationally recognized as a protector and has been worked on in many parts of Europe to eradicate horseradish with good results.
The genotype has never before been found in sheep in Iceland, despite extensive searches. Matís has been offering scrub gene analysis since 2004. Matís has traditionally sequenced the scraping gene in about 3,500 sheep and never before found this variability. Specialists at the University of Iceland Laboratory of Pathology at Keldur have also conducted a systematic search for this genotype for years.
Matís received samples for analysis from an extensive research project carried out by RML, the University of Iceland Laboratory of Pathology at Keldur and Karólína Elísabetardóttir, a sheep farmer in Hvammshlíð. The analyzes confirmed the previous result, but at the same time four additional related artefacts were found on the farm that carry this genotype.
Matís is currently working in collaboration with Stefanía Þorgeirsdóttir, a specialist at the University of Iceland's Experimental Center for Pathology at Keldur, on the introduction of new methods for diagnosing the scraping gene. The aim of the study is twofold. First, to add more genetic sites to the regular analysis, including the newly discovered protective genotype (site 171) and possibly more variable sites within the scraping gene. Secondly, ways will be sought to increase the efficiency and capacity of scrapie analyzes, with the aim of reducing the cost of analyzes so that it will be possible to reduce the price of analyzes to farmers.
Stykkishólmsbær and Matís have reached an agreement on the development of co - operation in the municipality of Stykkishólmur with an emphasis on education, innovation, research and business development within the municipality. Both parties to the agreement will make the most of their respective strengths and infrastructure.
Stykkishólmsbær held a brainstorming meeting with Matís, KPMG and representatives of the business community in the area on 26 November. Representatives of the business community were educated and a lively discussion ensued about the opportunities for increased value creation and the strengthening of the business community regarding sustainable food production in the area.
Growth in employment and innovation in Stykkishólmur
The mayor, together with the chairman of the Business and Innovation Committee, visited companies in Stykkishólmur in order to become better acquainted with the activities of companies and institutions in the town as well as the available challenges and opportunities and explore how Stykkishólmsbær can better support the interests of the business community in its policy and advocacy..
"The economy is a foundation based on each place and the lifeblood of all societies. It is important to be in good contact with the business community and understand its needs, " according to Jacob.
The town council of Stykkishólmsbær appointed a working group to strengthen the town's economy, which is now working to identify opportunities for strengthening the economy on the basis of regional strengths that will be useful in the town's employment strategy. The working group includes representatives from the Association of Local Authorities in Western Iceland and the Institute of Regional Development. Among other things, it looks at value creation in connection with the sustainable utilization of Breiðafjörður's resources. Is the agreement of Matís ohf. and Stykkishólmsbær are part of the same journey.
"With this, Stykkishólmsbær wants to ensure favorable conditions for companies, be a driving force for good works and support research and innovation," underlines Jacob.
Agreement signed at a brainstorming meeting in Stykkishólmur
Several representatives of the business community in Stykkishólmur, together with the mayor and the chairman of the business and innovation committee, had a brainstorming meeting with representatives from Matís and KPMG on 26 November.
The meeting discussed research, innovation, start-up activities, food production and responsible utilization of Breiðafjörður's resources with the aim of promoting sustainable utilization of resources and increased value creation in the area. At the end of the meeting, Jakob Björgvin Jakobsson, mayor, and Oddur Már Gunnarsson, CEO of Matís, signed an agreement on cooperation between Stykkishólmsbær and Matís.
There is a lot of growth and development in the field of sustainable product and food production in Stykkishólmsbær and the goal of Stykkishólmsbær and Matís is to support as much as possible individuals and companies in the area for value and innovation in the food industry and further processing of regional products, and thus promote increased prosperity, food security, food security and improved public health for Icelandic society.
Recently, a report was published on the results of continuous monitoring of undesirable substances in seafood from the resource for the year 2021. For years, Matís has been responsible for tasks related to collecting data and publishing a report on this systematic monitoring.
The aim of the project is to demonstrate the status of Icelandic seafood in terms of safety and health, and to use the data in the risk assessment of food to ensure the interests of consumers and public health.
The project builds a knowledge base on the amount of undesirable substances in economically important species and marine products, it is defined as a long-term project where expansion and revision are constantly necessary.
The results showed that Icelandic seafood contains insignificant amounts of persistent organic pollutants such as dioxins, PCBs and pesticides. At the same time, all samples of seafood for human consumption were well below EU maximum levels for persistent organic pollutants and heavy metals. The concentration of so-called ICES6-PCBs was also found to be low in the edible part of the seafood, compared to the EU maximum level.
Further explanation of the results as well as the report as a whole can be found here:
Last night the series began We eat and enjoy on the RÚV, but in the episodes a diverse group of people will be watched, and their nutritional and eating habits will be thoroughly reviewed in order to see how it is possible to combine these two issues, ie. to be nourished and enjoyed.
The episodes Nærumst og njótum are conceptual and supervised by Anna Sigríður Ólafsdóttir, professor of nutrition and are an important contribution to public health in Iceland. In this first episode, the audience got to know the subject, participants and opinion leaders, but in the next episodes, the food life of seven homes in Iceland will be followed. The homes are diverse, ranging from people living alone to large extended families and participants ranging in age from 10 weeks to seventy.
"Food is a common thread through our lives, but sometimes we eat just to stay alive. Namely, food is an integral part of physical, mental and social health. We are emotionally connected to food and it is a big part of our culture."
Kolbrún Sveinsdóttir, food scientist and project manager at Matís, is one of the experts hired to give opinions and discuss various issues related to food and eating habits. She focused on processed foods, the difference between them and fresh foods, and the various processing methods that can be both good and bad.
The episodes will be on the RÚV program in the next few weeks, but the first episode is already available in the player here: Eating and enjoying, first episode.
On New Year's Day 2022, a solemn ceremony took place in Bessastaðir when the President of Iceland, Guðni Th. Jóhannesson honored 12 individuals with the Icelandic falcon word. Among them was Matís' chief engineer, Sigurjón Arason, who received the award for research and development in the processing of marine products.
Sigurjón Arason has worked for Matís from the beginning, but before that he worked as a specialist and chief engineer at the Fisheries Research Institute, which merged with other companies and institutions when Matís was founded. Sigurjón is also Professor Emeritus at the Faculty of Food and Nutrition at the University of Iceland and has throughout the years taught countless courses and supervised a number of students in undergraduate, master's and doctoral studies.
Sigurjón has received various awards for his work and, among other things, a seminar was held in his honor at the University of Iceland this autumn.
Various partners and benefactors of Sigurjón attended and spoke at the honorary symposium held at Veröld, Vigdís' house in October.
In an interview with Sigurjón and published on the University of Iceland website under the heading The innovator from Neskaupstaður the following is stated:
"Sigurjón has been involved in an incredible number of projects that have resulted in net income for Icelandic companies and the economy. Together with numerous business partners and the knowledge society, he has been involved in developing revolutionary methods for cooling fish, including mackerel, which has greatly increased the export value of the products. He has also contributed to the processing and drying of underutilized by-products and fish species, redesigned packaging and fish boxes to ensure better quality of raw materials and products, developed fish freezing and salted fish processing to increase value, worked on improved catch handling and improved fish shelf life, improved shelf life on fishing and the use of fishing gear. Furthermore, he has found ways to make better use of by-products from raw materials that were even thrown away, but this includes fish guts, liver, dill, heads, ridges, swimming belly and skin that was turned into valuable products. There is little to be said here. "
Sigurjón is well on his way to this honor and Matís' staff congratulates him on the word falcon.

Seaweed is a sea plant and is in fact an unused resource of biomass that is found in large quantities all over the world, including off the coast of Iceland. Seaweed has become much more common than thatwas previously in people's daily consumer goods, for example in food supplements, cosmetics, medicines and food. In recent years, a number of diverse projects related to seaweed, its properties and utilization have been carried out at Matís. Among them are the projects Súrþang and SeaFeed, which have been managed by Elísabet Eik Guðmundsdóttir and Ólafur H. Friðjónsson. We talked to Elísabeta Eik about the possibilities of research of this kind.
Seaweed contains a lot of bioactive substances and many of them have been described as beneficial to health, including prebiotic. Research on seaweed is growing rapidly in the world, as it is available in large quantities around the world. In many places, seaweed can be harvested in a sustainable way and its cultivation does not require land or fresh water. At Matís, emphasis has been placed on researching complex carbohydrates and bioactive substances in the seaweed, with the aim of creating value through new products or methods. Seaweed substances have all kinds of bioactivity, for example they can be antioxidant, affect the inflammatory response, fight bacterial infections and more. Bioactivity is when something affects living processes and we are trying to see and find what a good effect they can have.
Various types of algae off the coast of Iceland
The projects Seaweed and SeaFeed have mainly focused on the development of a fermentation method for seaweed with the aim of using fermented seaweed, so-called seaweed, to be added to aquaculture feed. These research and development projects have been carried out in collaboration with Laxá fiskafóður, the University of Helsinki, the Quadram Institute in the UK and Þangverksmiðjan Thorverk, with grants from the Rannís Technology Development Fund, EIT Food, AVS and the Food Fund.
What were the main objectives of the research?
The main objectives of the projects were to develop a product with positive health properties from seaweed for use in aquaculture feed and thus bring underused biomass into the food chain. We envisioned such research that it would benefit the rapidly growing seaweed industry and contribute to increased value creation from seaweed. Feed producers could then also develop new feed mixtures and aquaculture companies could use feed from Icelandic materials.
Fermentation, beneficial bacteria and improved intestinal flora
The processing of seaweed begins with dried and ground seaweed which is prepared for fermentation by a method which involves soaking the seaweed in water and heating it to 70 ° C. As a result, carbohydrates are released from the seaweed into the solution and at the same time a large part of the seaweed's microbial flora is killed.
After pre-processing of the seaweed, it is fermented with lactic acid bacteria from the genus Lactobacillus but the strain used can use mannitol, a sugar alcohol found in algae in large quantities, for growth and metabolism.
Experiments with seaweed processing
The fermentation process makes the seaweed easier to digest and makes oligosaccharides more accessible. Analysis of the hydrocarbon content of the seaweed after fermentation revealed that branched oligosaccharides are still present in the product but are not eaten by the fermentation bacteria.
This is important because sugars play a bactericidal role. In other words, they stimulate the growth of beneficial bacteria in the intestines of farm animals. Lactobacillus the strain itself is considered a beneficial bacterium and this mixture of beneficial bacteria and a bactericidal stimulant oligosaccharide makes seaweed a product with multifaceted activity.
The situation today gives good hope for the future
The products of the projects have been tested in aquaculture experiments where salmon were fed on traditional fishmeal feed with fermented seaweed of two types and without seaweed for comparison. The growth of the fish and the effect of the feed supplement on their intestinal flora were monitored, as well as chemical analyzes and sensory assessments of the salmon product.
During sensory evaluation, samples of salmon from all feed groups were evaluated in triplicate by 8 trained sensory judges with regard to 17 factors describing the taste, smell, texture and appearance of salmon and no significant difference in taste, smell or texture was found between the three feed groups. Consistent with the sensory assessment, no significant differences in the taste or texture of salmon from different feed groups were found in a public consumer survey.
Measurements were also made on the color, protein content, fat and water in the salmon, but there was no significant difference between the groups when looking at these factors. Heavy metals have also been measured in salmon, but it is known that seaweed often contains a lot of heavy metals, especially iodine. It was clear that the high iodine content of certain types of seaweed is transferred to the salmon. High iodine content can have a positive effect here as iodine deficiency is widespread in the world and is considered a serious health problem. However, iodine is the factor that limits the amount of seaweed that can be contained in feed so that it does not have a bad or unhealthy effect, according to current regulations on the maximum value of heavy metals in feed. Other major heavy metals such as arsenic, lead, cadmium and mercury were all well below the feed threshold and there was little to no difference in these substances in salmon fed seaweed compared to salmon fed conventional feed.
The intestinal flora of salmon fed seaweed was shown to contain significantly less bacteria from genera containing known pathogens in fish compared to the intestinal flora of a control group fed on conventional non-seaweed feed. These results give good hope that the addition of seaweed to feed has in fact had a positive effect on the intestinal flora of farmed salmon.
As things stand today, the fermentation method has been developed and the product tested in aquaculture. Further research is underway to answer some outstanding questions and further improve the quality and safety of the feed supplement. Further development of the product is underway and it is planned to repeat the aquaculture experiment for confirmation in 2022.
What do you think is most exciting about research on seaweed?
The most exciting thing about the stage as a whole is that we are taking biomass that we have and lying there loose that we are not using and we are creating something from it. We are creating value by creating a product in the end, but we are also just exploiting it. As the situation is today in Iceland, we are not overusing our seaweed at all, we are using a very small part of what we could use. The seaweed is harvested in an environmentally friendly way and it only grows wild in Iceland as there are no domestic parties cultivating seaweed as it is today. There is a lot of material in there that contains all these possibilities and all these products. That's what's most exciting and drives it forward. We are all trying to work towards a greener future. And use what the earth gives us, do not overuse but use it well.
