Dried kelp sold out of the country

Among the food companies that have used Matís' expertise is Íslensk bláskel og sjávargróður ehf. in Stykkishólmur.

The company, which was founded in 2007, collects and grows mussels and collects seaweed in an environmentally friendly and sustainable way in several places in Breiðafjörður. "We have had a pleasant collaboration with Matís for several years. There are many very talented scientists with extensive experience that are good to look for, "says Símon Sturluson, one of the owners. He says that it is very important that Matís' knowledge network extends far beyond the rocks so that they do not have the knowledge they need each time, they know where to look for it and can access it.

Following on from the mussel farm, the company has now started experimental exports of dried kelp to Denmark, Norway and Spain. Símon says that the kelp is usually sold dried, as this is by far the best storage method. "The market for kelp products is very large, we consider ourselves to be of high quality and therefore want a good price for our products. That's why we avoid all unnecessary intermediaries and try to sell directly to the restaurants, for example. This is all coming but it happens in the calm heat, "says Símon.

Nordic conference on consumers and sensory evaluation

Every other year, conferences on sensory evaluation and consumer research are held in the Nordic countries, and Matís has taken part in their preparation.

The next conference, which is the 15th in a row, will be held in Helsinki on the 22nd-23rd. May 2013 and is entitled "Innovations in sensory evaluation and how to reach different consumer groups (Novel sensory approaches and Targeting different consumer groups).

The conference is intended for both professionals in the food industry and scientists in this field. The interest and participation of people from both large and small food companies in attending these conferences has steadily increased in recent years, as it is an ideal forum for industry and scientists to meet and establish a communication network in this field. About 100 people are expected, mostly from the Nordic countries.

The topics of the conference this time are innovations in sensory assessment and how to reach different consumer groups such as children, the elderly and those who are health-conscious. Emilía Martinsdóttir, Matís' director, is on the conference's preparation and science committee. She will speak at the conference, which is based on the results of the Nordic project Enrichment of Seafood and is, among other things, carried out in collaboration with the company Grím kokk. Dr. Kolbrún Sveinsdóttir, director of Matís, will give a talk on young people's fish consumption and how it can be increased. The conference will also feature presentations on food that appeals to older people, but interest in this issue is growing rapidly in the Nordic countries and in Europe.  

Registration runs until April 19. The conference fee is lower if booked before 31 January 2013. People in the food industry in this country and others who are interested in this topic are encouraged to register their participation as soon as possible. 

Sensory evaluation and sensory evaluation research have long been an important area of expertise at Matís, and the emphasis has increasingly been on consumer research. Matís has participated in many domestic and foreign research projects regarding sensory evaluation and food quality and held various sensory evaluation courses for employees of fish processing companies and other food companies. Matís' staff has also taught sensory assessment and consumer studies at the Faculty of Food Science and Nutrition at the University of Iceland and at Fisheries Science at the University of Akureyri. Matís staff also teaches sensory evaluation at the United Nations Fisheries Academy.

Lots of work in biotechnology research

"Matís' biotechnology workshop in Sauðárkrók plays an important role in biotechnology research. The term biotechnology appears more and more often in discussions about innovation in the business world, and success has already been demonstrated in research projects in the field of biotechnology that have yielded valuable bioactive substances, both for product production here in the country and for export," says Dr. Hólmfríður Sveinsdóttir, project manager at Matís.

An example of this is the UNA skin products, which are based on the bioactivity of substances from seaweed that originate, for example, in Breiðafjörður. Part of the research on the bubble seaweed took place at Líftæknismiðja Matís in Sauðárkrókur, but the products are manufactured in Reykjavík, so it can be said that the entire development and production process has a contact surface in a large part of the country.

Matís Biotechnology Center is located in one of the most powerful food processing districts in the country, Skagafjörður. There she works alongside companies in the seafood production, meat and dairy industries that have taken advantage of the proximity in collaboration on research projects. An example of this is a project for FISK Seafood that aims to increase the traceability of the company's seafood products. Matís in Sauðárkrókur also has significant collaboration with Hólar University, thus achieving better utilization of both research facilities and an increased common knowledge base in the area.

"Great value lies in the bioactivity of materials. In research at the Biotechnology Workshop, the spotlight is directed, among other things, on the positive effects of fish proteins on blood pressure and the positive effects of substances derived from seaweed and sea urchins on blood sugar. Once this bioactivity has been demonstrated through research, the value of the bioactive substances multiplies. Therefore, it is important to work," says Hólmfríður.

Valuable and successful collaboration with Marel

Marel has long been a key player in the fish processing chain in Iceland with its technical equipment where emphasis is placed on raw material quality and processing speed. Matís' collaboration with Marel is extensive and both parties benefit significantly from it.

"Within Marel, a lot of valuable knowledge has been built up about processing technology in the food industry, not least in the fishing industry," says Sigurjón Arason, chief engineer at Matís and professor of food engineering at the University of Iceland.

There has been a collaboration between Matís and Marel for many years and, for example, two of Sigurjón's students now work for the company but were previously Matís employees. Both of them worked on projects related to fish processing companies in their work at Matís, and Sigurjón says that it is valuable that their knowledge is used in technological development within Marel.

"Collaboration between us is first and foremost project-related and from Matís we invest in the development of our research capacity and knowledge of raw materials and the effects of processing on it. It is essential to look at the entire fish processing process, from fishing to the consumer, as it is not possible to create good fish products if the quality of the raw material is not available. Technology can never make up for poor raw materials, "says Sigurjón.

"In recent years, researchers have become increasingly involved in the development, both the development of technological solutions such as at Marel and research into the floor at the processing companies. After all, we sometimes say that there are our best experimental rooms in the research work. There we can test ourselves further, make our measurements and use the results as soon as they are created. Matís is therefore very important to be able to work alongside companies such as Marel and at the same time increase our relationship and cooperation with the fish processing companies. It is to the advantage of the Icelandic fishing industry.

Today, the research work is increasingly about the development of the processing processes as a whole, and as a result we look at the raw material treatment at sea, as well as factors related to the transport of products to the market, packaging of products and so on. The process itself looks at the integration of technical equipment, and in time this development may lead to changes that in the future will be referred to as a revolution. The goal is to create even better products - even more value from what the resource provides, "says Sigurjón Arason.

Promotion of education and training in food production

"With the establishment of a division for education and food production, we make Matís' activities and role more prominent and better connect the business community, education, research and development of food," says Guðjón Þorkelsson about the new field of education and food production that started working within Matís on the 1st. June 2012.

Grants both Matís and the food companies
Guðjón says that through collaboration with educational institutions and vocational training, Matís is following up on the emphasis on research and innovation in the field of food for the benefit of the economy, public health and food safety. 

"Another main reason for the collaboration is efficiency in the form of shared use of staff and facilities. The other reason, and the one that is of great importance to Matís and the food companies, is to get students to work on practical research projects and thus gain training to become the companies' future employees. Matís is a very large research company on an Icelandic scale and here is a great deal of expertise and experience that needs to be utilized in teaching, guidance and vocational training in food processing. We are also lucky to have received first-class facilities in many places in the country that are also used for the same purpose, "says Guðjón.

The teaching component has already become extensive
Despite the fact that teaching, vocational training and guidance of students in research studies have so far not been in a fixed and organized form as a field within Matís, Guðjón says the scope of these aspects is very large.

"Matís employees teach about 25 courses in undergraduate and graduate studies and supervise most of them. Numerous students in master's and doctoral studies at Icelandic universities have worked on their research projects at Matís and almost always in collaboration with the business community. We are in good cooperation and have joint employees with the University of Iceland and the University of Akureyri. The collaboration with the University of Iceland is mostly at the Faculty of Food and Nutrition, but also extensively at the School of Engineering and Natural Sciences and the School of Social Sciences. Matís works extensively with the School of Business and Science at the University of Akureyri, mainly in aquaculture and fisheries sciences. Due to previous work and research, I have a strong desire to revive and strengthen the collaboration with the Agricultural University of Iceland. Hólar University and Matís are in a joint building at Verin in Sauðárkrókur and work together on many projects.

All of these parties have worked on a project to establish an international master's program in food science in connection with the food industry in the country. This course has been led by Matís and the University of Iceland and 12 students started the course this autumn, "says Guðjón, but most of the teaching is at Matís in Reykjavík, but teaching also takes place in Akureyri. In connection with the study, two Matís specialists, Hörður G. Kristinsson and Helga Gunnlaugsdóttir, were appointed visiting professors at the University of Iceland.

"I have full faith that the international master's program will strengthen and become very prominent in the coming years. Cooperation on other sectors will also be strengthened. Our task must also be to link vocational training, technical studies and other university studies related to food to the economy. We also need to work on strengthening vocational training / vocational rehabilitation related to food with an emphasis on small-scale food production and collaboration with Beint frá býli, "says Guðjón Þorkelsson division manager at Matís.

Improved reefer container for fresh fish - Final report

The main goal of the project Improved refrigerated container for fresh fish was to improve refrigerated containers and procedures for transporting fresh seafood through redesign and testing. The aim is for design improvements to deliver refrigerated containers that reach a more even temperature throughout the transport process. Efforts should be made to achieve satisfactory improvements to refrigerated containers that are used today with simple and inexpensive measures. The consequences of improved temperature control in production and transport processes are increased quality, stability and safety, which at the same time increase the value of the product. Partners in the project were Matís, the University of Iceland, Eimskip Ísland and Samherji. This report describes the main results and products of the project. The results of the project showed that improvements are needed in maritime transport chains and it was shown that improvements can be achieved with simple and low-cost measures. Temperature control for sea transport can be improved by choosing the target temperature and cooling containers that are best suited for transporting fresh fish products. Mapping the heat distribution of refrigerated containers showed variability both in the transport process and in terms of location within the container, but design improvements aimed at forcing airflow within the container resulted in a more even heat distribution. The importance of procedures for loading refrigerated containers and their handling from manufacturer to buyer was also demonstrated.

The purpose of the project Improved reefer container for fresh fish is to use simple redesign and experimental testing to improve temperature control in reefer containers and work procedures of fresh fish products during transport. The design improvements are aimed at producing a reefer with more stable temperature through sea freight and transport. The aim is to get satisfactory improvements with simple and cost effective procedures. Improved temperature control in fish chill chains leads to increased product quality, stability and safety and thereby increased product value. The project was done in collaboration with Matís, University of Iceland, Eimskip Ísland and Samherji. This report describes the main results and products of the project. The results of the project showed that there is room for improvement in sea transport cold chains and with design improvements experiments it was demonstrated that they can be improved with simple and cost effective procedures. The results showed that the temperature control during sea freight may also be improved by selecting the reefer types most suitable for fresh fish transport and selecting different set point temperatures during summer and winter. The mappings of temperature distribution inside the reefers showed spatiotemporal variability and design improvements achieved a more uniform distribution by means of forced air circulation. Field tests demonstrated the importance of correct operating procedures during loading of reefers and their handling from processor to end location.

Use of electricity for drying fishmeal / Electric drying of fish meal

The fishmeal industry is an important industry and has been technologically advanced in recent years. High energy is used in the production of products. In order to gain a better grasp of energy efficiency in the process, an energy and mass flow model is set up for the processing of different raw materials and at the same time a better overview of the processing cycle is obtained. The model also helps to make it easier to influence the quality of fishmeal products, through process control. The main goal of the project is to control energy consumption in the production process and especially during drying and to develop electric drying equipment for air dryers. The drying is the last stage of processing in the circuit and the waste dryer from drying is then used later in the circuit. The aim of the project is to use electricity to heat air for drying fishmeal in an efficient way. In this way, it would be possible to achieve the goal of the fisheries sector to utilize only domestic energy in the production of fishmeal, significantly reduce the import of oil for land processing and significantly reduce the formation of footprints. Measurements in the production process were performed for four types of raw materials, to estimate material flows through the factory. Pressure drop over oil heating equipment was measured and is much higher compared to electric heating equipment. The electric heating equipment has proven successful in HB Grandi Vopnafjörður's fishmeal factory, in terms of energy source, energy efficiency, control and maintenance.

The fish meal industry is an important sector and has applied technology in recent years. Fish meal processing is an energy intensive process. For better control of energy utilization in the process energy‐ and mass flow model was set up for processing different raw material, and simultaneously a better overview for the process. The model is a good tool to have influence on the quality of the fish meal products. The main aim of the project was to control energy usage specially for the drying and to develop electric air heating equipment. The drying is the last step in the process and waste heat is utilized on previous stages in the process. The aim of the project is to utilize electricity to heat air for drying fish meal in a cost effective way. By contrast it would be possible to reach the goal for the Icelandic marine sector to utilize exclusively domestic renewable energy for fish meal processing, reduce imports of oil for shore processing and reduce carbon footprint. Measurements in the process were carried out for four kinds of raw material, for evaluation of mass flow through the process. Pressure drop over the oil air heating equipment was measured higher than for an electric air heater. It has turned out that the electric air heater has proved its worth in HB Grandi fish meal factory in Vopnafjordur, in terms of energy source, energy utilization, controlling and maintenance.

Offshore Aquaculture: Development, building and testing of a deep water mooring system

Offshore Aquaculture: Development, building and testing of a deep water mooring system

Emphasis on healthy and safe foods has boosted seafood consumption. At the same time, increased demands for the sustainable use of seafood have encouraged farming and cultivation instead of fishing for wild species. Limited space in coastal areas, however, is hampering global aquaculture production. It is therefore expected that aquaculture and the cultivation of seafood will increasingly move out of the shelter of bays and fjords and more into open sea areas. This change will increase the demands on equipment for offshore fishing, as work will need to be done at greater depths and to deal with conflicts caused by offshore waves and ocean currents. Concrete blocks and traction anchors are traditional equipment for aquaculture production of seafood, but aquaculture manufacturers are now looking for safer and cheaper methods of attaching their equipment to the seabed. Concrete blocks and tug anchors are unsuitable as anchors as they are expensive and need to be very heavy to be used on the high seas, as well as they require a lot of space as they do not withstand vertical conflicts from the environment and / or service boats. Large ships with powerful equipment must be used to bring them far from shore, and this is a very costly operation. Tæknistál ehf. has developed an underwater drill based on new technology that attaches a light screw anchor to the seabed, all the way down to a depth of 70 meters, without the assistance of divers. The project was carried out in collaboration with Matís ohf., Siglfirðing ehf., Ocean Rainforest spf., Offshore Shellfish Inc., SINTEF MRB (R&D) and partly financed with a grant from Tækniþróunarsjóður and NORA. The drill is light, weighing about 900 kg, and is based on a three-point frame with three screw drills at each corner that attaches it to the seabed. Then a screw anchor, up to four meters long, is drilled into the seabed with a fixed service line. Due to the light weight of the bearing, it is possible to use traditional service boats for fire / cultivation, to anchor. Compared to traditional anchors, such as concrete blocks and tow anchors, such drill anchors are considered more environmentally friendly, cheaper and can withstand much more vertical effort and therefore require much less space for fire / cultivation. Such properties are important for aquaculture / cultivation in the sea, but no less for other uses such as floating docks or ammunition. The drilling rig that was developed in the project has passed various effort tests, but it was also tested in mussel farming under real conditions for the open sea for 6 months in Eyjafjörður. Tests took place during the winter in the worst conditions and showed that the anchors held perfectly and withstood the load much better than traditional anchors (concrete blocks) did at the same time. Marketing of products and technical solutions developed in the project is well under way.

With ever increasing seafood consumption and greater environmental concerns for healthier and safer products, the demands on aquaculture production are rising. Limited space for suitable aquaculture sites along coastal zones is now recognized worldwide as a serious limitation for this important industry. The farming or cultivation of seafood is therefore expected to shift increasingly from sheltered fjords and bays to more exposed offshore culture sites. This expansion offshore, away from the visibility of coastal communities, means installing and anchoring aquaculture infrastructures at greater water depths in rough sea. Thus, in order to eliminate the logistical difficulties imposed by transporting and positioning heavy deadweight concrete anchors or drag ‐ anchors offshore, aquaculture operators are seeking more cost ‐ effective and practical mooring solutions like deep water drills using light ‐ weight anchoring systems. Compared to traditional fish farming in sheltered fjords and bays, offshore aquaculture gear requires a much greater holding power as it is highly exposed to considerable physical forces eg by waves and currents. One of the remaining challenges for this offshore expansion is the costly installation of heavy concrete or drag ‐ anchors to hold the aquaculture infrastructures at considerable water depths. Producers are therefore looking for more cost ‐ effective and reliable mooring systems that can be quickly and easily installed, to meet the increased biomass potential. Taeknistal Inc. has developed a new technology to fasten light ‐ weight helical screw anchors into the seabed, at water depths up to 70 meters below surface, without the assistance of divers. The project was carried out in collaboration with Matis Inc., Siglfirdingur Inc., Ocean Rainforest spf., Offshore Shellfish Inc., SINTEF MRB (R&D) and partly financed by grants received from the Technology Development Fund in Iceland and NORA. An innovative drill machine was specially developed for installing helical screw anchors into the seabed. The submersible structure consists of a triangular drill frame with three small drills, using helical screws that are fixed to each corner of the triangle at the bottom of the drill unit. This drilling machine has the advantage of being light ‐ weight, approximately 900 kg, and can be managed by an ordinary aquaculture service vessel. Compared to the traditional anchor types, such as concrete blocks or drag ‐ anchor, the helical screw anchors are more environmentally friendly, less expensive and more resistant to vertical tension. These are all important factors in aquaculture, especially offshore where one can expect high waves and strong currents, in addition to the tension imposed by the larger service vessels when they are attached to the aquaculture lines. Managing the innovative drill machine was tested at open sea and the holding power of the anchors was tested in actual conditions during six winter months, where the screw anchors were drilled into the seabed at an offshore aquaculture site at Eyjafjordur (North Iceland). The results from this test demonstrated that the screw anchors have a holding capacity superior to that of traditional anchors which minimizes the loss of crop, and reduces the environmental impact. Marketing of the products and the technical solutions developed in the project is well under way.

Raw material process in shrimp factories

Shrimp processing has been very successful in improving the utilization of raw materials, and the utilization has decreased from 20% to over 40% in just over twenty years. The use of poly ‐ phosphate (PP) has been important in this process, but these substances have been used together with salt and citric acid as excipients in the pre-processing of the shrimp. Utilization has been the best in the processing of thawed raw materials, but utilization has been significantly poorer in fresh shrimp. In Kampa shrimp processing, fresh shrimp are divided into two main categories; deep-sea shrimp and deep-sea shrimp caught in Ísafjarðardjúpur or Arnarfjörður. Ocean prawns have given better utilization than deep-sea prawns, which in most cases are smaller. The main purpose of this project was to compare the activity of these substances on thawed and fresh shrimp to improve utilization for the latter category. A study was set up to measure weight gain with differently strong blends and different times on fresh shrimp. Three experiments were performed, the first with both deep-sea shrimp and deep-sea shrimp, and the second two with only deep-sea shrimp. Studies were conducted from October 2011 to June 2012. The results of these studies strongly indicated that the pickling time of fresh shrimp needed to be shortened compared to thawed, but a traditional mixture gave the best results. This project was to test snail equipment from 3X Technology, Rotex, and compare the result with the traditional Kampa method, with 660 l. kerum. A new and cheaper method was introduced before this part of the study was carried out and it was therefore decided to cancel that part of the project. Instead, it was decided to focus on chemical research into the uptake of PP substances and what effect this would have on utilization in shrimp processing. Extensive research was started, but its scope is more than enough for a small project like this. Further research is therefore needed to complete this project, but the results obtained from this project are a good basis for further research. The result of the project is improved utilization for pelleting of deep-sea shrimp and deep-sea shrimp, which yields approx. one percentage point during processing.

The shrimp industry has achieved great success in improving the utilization of raw materials with the yield going from about 20% to over 40% in just over twenty years. Use of polyphosphates (a „poly ‐ phosphate„ (PP)) has been important in this process, but these materials have been used along with salt and citric acid as an excipient in the preliminary raw material method for shrimp. Best result has been in processing defrosted (frozen raw material) material with lesser yield using fresh material (unfrozen raw material). Kampi shrimp factory are mainly using two types of fresh raw material, in ‐ fjord shrimp from Arnarfjordur and Isafjardardjup, and deep water shrimp from fresh ‐ fish trawler fishing north of Iceland. The in ‐ fjord shrimp is generally smaller than the deep ‐ water shrimp. The main purpose of this project was to find a way to gain yield in processing the fresh material, and to transfer success in processing the defrosted shrimp to the fresh material. To do so a different strength of ingredients in pre ‐ maturing fluid in raw material method was used along with different time of maturing. The effect of this experience was recorded. Three experiments were conducted, the first with both in ‐ fjord shrimp and deep water shrimp, but the latter two with deep water shrimp only. Studies were conducted from October 2011 to June 2012. Results of these studies strongly indicated that a shorter time should be used for fresh material to gain better yield, but traditional combination of ingredients for maturing blend gave the best result. The second objective of this project was to test Rodex equipment from 3X Technology for raw material processing and compare the results with the traditional method Kampi uses, with 660 l. tubs. Before the test was conducted a new and cheaper method was introduced to this market, making the Rotex equipment unrivaled in this business. The project management team then decided to cancel this part of the project and to focus instead on chemical absorption studies for PP materials and the impact it would have on the utilization of the shrimp. Extensive studies were begun, but their scope is more than can be accomplished in a small project like this one. An advanced project will be needed to complete this study but the attainment of this study is an important input for further research in this area. The yield in fresh shrimp processed in Kampi have improved for about two percentage points as a result of this project, by using different maturing method for the raw material.
