Seaweed underutilized resource in Iceland

"Icelandic seaweed is an underutilized resource, at least in Iceland, but there are various things related to algae and they are relevant in our research," says Jón Trausti Kárason, an expert who is one of those associated with algae research at Matís.

Jón Trausti says that about 8 researchers at Matís work primarily on algae research, although more are related to those projects in one way or another. Among the recent products based on algae research by Matís scientists are skin products that the start-up company Marinox has launched, but they contain bioactive antioxidants that are made from seaweed and are considered particularly good for the skin. Among other products that are expected to be on the market soon, Jón Trausti mentions algae skyr and barley paste that is added with algae.

"In fact, it was a group of students who were with us last summer that started the development of the algae cloud and the product competed on behalf of Iceland in Ecotrophelia, which is a student competition in environmentally friendly innovation in food production. This went so well that the development work was continued and now the algae cloud is coming to market. Here is food on the go that is skyr and kelp flour in the base but flavored with blueberries and honey, "says Jón Trausti.

The Product Development Center for Marine Products increases value creation

It can be said that this is a kind of umbrella for many small projects that are carried out within Matís in collaboration with companies and individuals around the country and aim to increase the value of seafood.

"The Fisheries Project Fund enabled us to give new and small projects a go without having to seek support for each of them through applications to larger funds," says Páll Gunnar Pálsson, project manager, about the creation of the Marine Products Product Development Center.

"It is often the case that we here at Matís are in contact with individuals or companies who need help to implement an idea or help to complete projects. They are often of such a nature that they are too small or have not reached the point where they match the emphasis of the competition funds due to the grant allocations. We felt that there was a great need for a new channel for these projects, as we at Matís have a lot to offer with our expertise and facilities. This can range from research or analysis to consulting on housing, technical solutions, product development or marketing. Basically, these are small projects, limited in time, but they can certainly expand in the future and then move to the level that suits the support system of the competition funds, "says Páll Gunnar.

Páll Gunnar says that the projects that the Product Development Center for Seafood is working on are very diverse. Some of them have already returned products to the market and are even the basis for the establishment of small companies.

 "Examples are the kelp skyr that will soon go into production, UNU skin products that have been placed on the market and are based on the use of bioactive substances from seaweed, and Gunna's Gunna á Rif, which received assistance with product development and quality control. This year, the projects are well into their forties and are working on improved utilization of grayling, seaweed supplements, fresh liver oil, live lobster packaging, seafood information for marketing and sales companies to name a few.

 The location of Matís' offices across the country has made it easier for entrepreneurs to seek cooperation and support. We welcome everyone and strive to strengthen the project ideas with our expertise so that the result will be increased value of seafood. "

Gæðasalt í saltfiskverkun / Quality salt for curing of salted fish

The main goal of the project was to use the geothermal sea in Reykjanes for the production of salt that can be used to produce high quality salted fish. A process will be developed to produce the salt with geothermal energy on site and to be able to control its chemical composition so that the correct effect of salted fish can be ensured. Salt extracted from the geothermal sea was compared with imported salt from the Mediterranean during the production of salted cod fillets with brine as pre-salting stage and dry salting at the end. The results showed that higher utilization was obtained in the salted fish processing with salt extracted from the geothermal sea, and that the processing took less time as the uptake of salt into the cod muscle was higher compared to the imported salt. Salt extracted from the geothermal sea was comparable in quality to the imported salt.

The aim of the project was to utilize raw material and energy from a geothermal brine to produce salt which can be used to increase the value in production of salted fish. Imported salt from Tunis was compared with the salt from geothermal brine, by producing salted cod from pickle salting followed by dry salting. The results showed that higher yield was observed in production of salted fish, by using salt produced from geothermal brine. Also curing took less time where the penetration of salt in the cod muscle was faster compared to the imported salt. The salt produced from geothermal brine is comparable with the imported salt.

Extraction of hydrolases from Gadus morhua / Natural enzymes from slag work

The aim of the project was to extract enzymes from catfish slag for use in releasing membranes and ringworms from the liver for canning. Extensive experiments were performed using different extraction buffers and the effect of salinity, acidity, temperature and time on the activity of four enzymes. The effect of cod liver enzyme mixture on the release of ringworm and liver from the liver was also studied compared to the use of Alcalasa 2.4G used in conventional processing. The results of the project indicate that extraction methods have a broad effect on the activity of enzymes, in addition to which different enzyme activity was obtained from individual organs compared to their mixtures. The activity of the tryps was measured rather high but seemed to be controlled by the salinity of the extract solutions and the temperature. The activity of trypsin appeared to be generally comparable to the results of previous studies on trypsin activity in fish stocks. The activity of pepsin was generally very low, indicating that it is not economical to process pepsin from cod fillets, at least not under the conditions tested. It is not considered convenient to co-treat trypsin, collagenase or elastase from slag as the maximum activity of the enzymes requires different extraction conditions. The results of the project as a whole indicate that enzymes can be isolated from cod stocks in a cost-effective way using methods that only require simple equipment and cheap solutions. The results of the experiments also show that these enzymes can be used to release ringworms from the liver for canning with similar results to the methods used today. However, it is not clear whether their use is beneficial for liver processing companies as it would be necessary to change the processing process in order to achieve maximum enzyme activity.

The aim of this project was to investigate and optimize methods for the extraction of proteases from the digestive tract of cod (Gadus morhua) in order to bring about membrane dissociation of cod liver prior to canning. Homogenized viscera were extracted using various salt solutions, buffers and pH adjusted solutions at different temperatures and time. The protein concentration and activities of trypsin, pepsin, collagenase, and elastase were analyzed. Selected extraction solutions where then used for the removal of liver membranes compared to traditional treatment with Alcalase 2.4G. The results indicate that enzyme activity is influenced by the extraction methods and different enzyme activity was furthermore obtained from different organs and their combinations. Trypsin activity seems to be governed by the salt concentration of the extract solutions and temperature. The trypsin activity was relatively high and comparable with those obtained from other experiments. Next steps may include further optimization of extraction depending on the target enzyme (s), whereas the optimum conditions for the extraction of trypsin seem to differ from that of collagenase. The results indicate that the extraction of marine proteases, with the exception of pepsin, from North Atlantic cod (Gadus morhua) is potentially feasible using materials generally recognized as safe (GRAS) such as dilute, aqueous sodium chloride solutions with relatively simple equipment. The marine proteases did remove worms from the liver to a certain extent but no clear trend was observed when comparing membranes of enzyme treated livers and controls under the experimental conditions of this study.

Bleeding system for small vessels

Extensive research has been carried out on the quality of cod bleeding, all of which indicate that proper handling has a significant effect on product quality. Studies have shown that poorly blooded fish produce worse products, whether it is fish that is processed into fresh, frozen, salted or dried products4. With the increasing influx of smaller boats engaged in longline and handline fishing, there has been a problem with bleeding, as many of them are not equipped with bleeding tanks. Matís' research indicates that fish that are allowed to bleed long enough in high seas, at natural sea temperatures, immediately after bleeding, produce better raw materials than with traditional treatment. A traditional method on board small boats is to bleed the fish directly from the line into the sludge tank on the train. Matís, 3X Technology and Fiskvinnslan Íslandssaga have completed the project "Processing processes of small boats" where conditions on board small boats were examined with a view to designing equipment that was suitable for smaller line boats. The design of the equipment (Rotex bleeding tank FIFO) has been completed and construction has begun at 3X Technology. The aim of this project is to investigate the efficacy of the Rotex method in cod bleeding through an objective study. This work is done in collaboration with 3X Technology, Matís and Jakob Valgeir ehf in Bolungarvík. Samples of cod were taken in two oars of a day rowing boat using different bleeding and finishing methods. Samples were filleted and some of the fillets were then sent fresh to Matís on Vínlandsleið, where different methods were used to assess the quality of the raw materials. The other part was done in the traditional way, ie. production of lightly salted, frozen fillets, and then used to obtain the effect of different bleeding methods on the quality of products during storage in the freezer, for different lengths of time and at different temperatures. The results of the project will support other research in this field better quality of catching small boats.

Extensive research has been conducted on the quality of bleeding process of cod on board but the correct treatment can have a significant effect on the final product quality. Studies have shown that insufficient bled fish will result in low value products, whether in the case of fresh, frozen or dried production. This problem is mainly related to fish caught by long ‐ line, especially on smaller vessels that are not equipped with necessary equipment for the bleeding process such as bleeding tanks. Researches indicate that bleeding of fish with sufficient flow of fresh seawater in the bleeding tank will result in higher quality products. The traditional bleeding method on board small vessels is to bleed the fish directly in to slush ice tub in the ship convoy. Matis, 3X Technology and Icelandic Saga have finished the research project “Processing in small vessels” where conditions on board the small vessels were examined with the aim to design equipment suitable for smaller long ‐ liners. The output of that project was the design of new equipment “Rotex” (bleeding tank FIFO). This was completed and a production was launched by 3X Technology. Samples of cod were collected in two fishing trips from a long liner landing daily, using different methods of bleeding and handling. Samples were filleted and parts of it were sent fresh for research at Matis in Vínlandsleid where different methods were tested considering different product quality and the other parts were prepared with traditional production of lightly salted fillet pieces. The fillets were frozen and used to test the effect of different bleeding methods on product quality after storage in the freezer, using different storing time and different temperatures. The aim of present project was to investigate the effect of the ROTEX bleeding process with an objective researches in collaboration with 3X Technology, Matis and the fish processor and boat owner, Jakob Valgeir Ltd. This project will support other researches in this area as well as to be an important input for disquisition about better quality of small boats catch.

The South is the heart of vegetable production

At the end of 2012, a decision was made to hire a joint employee with the University Association of the South for the Matís food factory in Flúðir.

Haraldur Hallgrímsson, division manager of Innovation and Consumers, says this is a very important step in the development of the food factory and a sign of its increased value in innovation and the development of food processing in the South.

"The employee of the food factory will map and support the development of food-related studies in the area, gather information about the needs of the companies and work with them, as well as handle the projects that are directly related to the food factory. This fits in very well with the emphasis we have in the food factories and I appreciate that in the South there are very great opportunities for Matís to support progress in food processing. We at Flúðir are at the heart of vegetable production in Iceland and one of the things we are looking at is to utilize experience that we can transfer from the fishing industry to that sector, for example in terms of processing methods, cooling, distribution technology and so on.

I believe that vegetable production will grow in the South in the coming years and we also see opportunities for innovation related to both agriculture and fisheries in the area. The grain farm is an example of this and in this context one can point to the production of the farmers in Þorvaldseyri. Matís' food factory in the South has therefore started well in the first year of operation and we are taking steps to strengthen it even further, "says Haraldur.

Value creation is the key word - It is important that knowledge becomes a product and values

At Matís, emphasis is placed on utilization and market thinking in all projects and activities of the company, because the rapid dissemination and utilization of knowledge is no less important than the basic research itself when it comes to products on the market.

Matís has great opportunities to implement and market the results of research and development projects, which leads to increased value creation for the Icelandic industries and to prosperity for the public in Iceland.

Value creation is therefore a key word in all of Matís' work, whether it is in collaboration with parties in Iceland or abroad. Here you can see a few examples of projects that Matís has had a role to play and have already returned value to the parties involved in the projects, whether looking at Matís as a company, its employees, customers or owners, ie. of the Icelandic state.
