Matís' autumn conference will be on Thursday

Food and the future, Matís' autumn conference, will take place at the Grand Hotel on November 15, 2007. The conference, which runs from 12:30 to 16:30, will seek to answer questions such as why vegetables are healthy, whether cod farming should be future for themselves in Iceland, why people do not want stressed farmed fish and whether people even know where their food comes from.

Thyme drinks and chocolate mountains

At the conference, it will also be possible to get to know food design, which is a growing part of the product design department of the Iceland Academy of the Arts. Guests have the opportunity to taste thyme drinks and enjoy the chocolate mountains. Tasting new farmed species They can also get acquainted with aquaculture species that are becoming increasingly popular abroad. These include tilapia and barramunda, for example. They will also have the opportunity to taste tilapia, which is becoming one of the most popular fish consumed in many parts of the world.

Matís finds a previously unknown thermal bacterium

Matís has found a previously unknown thermal bacterium, which seems to be bound to Iceland. The species was found in a high proportion in hot springs in the Torfajökull area and has now been successfully cultivated.

Matís has found a previously unknown thermal bacterium, which seems to be bound to Iceland. The species was found in a high proportion in hot springs in the Torfajökull area and has now been successfully cultivated.

Various studies have been carried out on thermal bacteria by Prokaria, Matís' biotechnology department. Modern methods allow scientists to detect species composition without culturing the bacteria. A previously unknown Thermus species, which appears to be confined to Iceland, was found using such methods. The species was found in a high proportion in hot springs in the Torfajökull area, but had previously been found in hot springs in the Hengill area.

Subsequently, interest arose in trying to isolate and cultivate this special Icelandic Thermus brand. Grants were received from the Research Fund and the National Energy Authority, and samples were taken from hot springs in the Torfajökull area in late summer and it was confirmed that Thermus islandicus was found there. Cultivation experiments on different foods, at different temperatures, acidity and oxygen concentrations have now finally yielded results in a viable strain which is now being studied further. Snædís Huld Björnsdóttir, an employee of Matís, has worked on this project, while Sólveig Pétursdóttir is the project manager.

Various Thermus species have produced valuable DNA enzymes that are used in research around the world. These include the enzyme DNA polymerase, which is used to amplify DNA to obtain multiple copies of a particular gene or fragment and a DNA ligase from the Thermus virus that glues DNA fragments. It is therefore not unlikely that the new species contains interesting enzymes.

Use of RFID tags in fish processing, process control and traceability

The aim of this project was to develop and implement RFID tags in fish processing. The project was funded by the ACP Fund. RFID tags are emoticons that emit radio waves. The project included the development of a methodology for maintaining batches from the reception of fish tanks and through processing, without slowing down the processing, the development of screw-on plastic caps with RFID tags to facilitate their replacement in fish tanks and the adaptation of RFID reading on forklifts. The project was supported by the results of two other projects, "Processing Forecast" and "Processing Forecast" and also benefited from work on the project "Profit Maximization". These projects have demonstrated the relationship between the origin of the catch and its processing characteristics and aim to use information recorded in fish processing to streamline and improve the management of the value chain of marine products, from fishing and to the market. A prerequisite for being able to use measurement results in forecasting is that the relationship between measurements carried out at different stages of production is known. In other words, the premise is traceability that is secured by RFID. The use of RFID tags in fish processing thus supports the work and development that has taken place in these projects, as the security and accuracy of the models used there are largely based on standardization in information processing. Such standardization is achieved precisely by implementing automation in the recording of material flows in the processing. The use of RFID tags has become quite widespread in retail, and the Wal-Mart retail chain has, among other things, taken advantage of the technology, which has been developing rapidly in recent years. It is considered to offer great potential for increased profits for companies in production and retail, among other things with less waste, improved possibilities for production and inventory management and possibilities for providing information to customers. Partners in the project were FISK Seafood, Matís, Maritech and Sæplast.

This project was aimed at developing and implementing RFID labels in fish processing. RFIDs are labels that transmit radio signals. The project included sustaining sequences from landing of fish tubs, through stockroom and processing, without slowing down the processing (sustaining sequences from catch to landing had been solved earlier). It also included the development of a plug, containing the RFID label, for easier exchange of labels and adjustments of RFID reading on a fork lift. The project took aim in, and collaborated with, other projects, such as “Processing forecast of cod” and “Contribution margin maximisation” (both funded by the AVS fund and Rannís), which have shown that the origin of catch and season of catch influences the processing properties of the catch. FISK Seafood, Matís, Maritech and Sæplast (Promens-Dalvík) collaborated on the project and it was funded by the AVS-fund, under the ministry of fisheries.

Gender analysis of fish

The aim of the project was to find a gender-related difference between the genetic material of pike and females in salmon, halibut and cod. This information was then to be used to develop a gender analysis test for these fish species. Gene and female repositories for the three species were prepared by subtraction pairing. The sequences obtained in the gene pool were sequenced, palpated, and then plated. The flakes were then paired with genetic material on the hens and females and the binding was assessed for the sexes. The project involved a great deal of technical and market innovation, combining high-tech methods from molecular genetics and information technology to solve the existing market problem in gender analysis in aquaculture. The risk in the project was whether there was a sufficient gender difference in the genome of these fish to detect it by flake analysis. This project was a great challenge and although the final goal was not achieved, it worked out in terms of methodology and great results were obtained. The project was therefore important for development and method development within the companies Stofnfisk, Matís-Prokaria and Nimblegen Systems in Iceland.

The goal of the project was to develop a sex determination method for the three fish species, cod, salmon and halibut. Gene libraries for female and male fishes were produced for the three fish species by using the subtraction hybridization method from whole genomic DNA. Probes were designed for all the sequences obtained and the probes were put on microarrays. The microarrays were hybridized with DNA from both male and female fishes and the difference scored. The risk of the project was to determine if there is enough gene difference between the sexes of these three fish species to be analyzed by using microarrays. The project did not reveal sex determination genes, but this assignment was a big challenge for the three companies Stofnfiskur, Matís-Prokaria and Nimblegen Systems. Many new methods and technical solutions were solved during the project and a large set of results were built up. The project was an important part of the fast growing and development of the companies.

"Fat is the bait" - bait from fishery byproducts

The aim of the project was to develop and produce composite baits for longline fishing from underutilized raw materials with newly developed snow technology that has been granted a patent. The chemical composition of bait raw material and the use of algae as antidote in bait were examined, in addition to which fishing experiments were carried out. In connection with the project, an application machine was designed and built, and experiments carried out with it in the spring of 2007 ended with 97% application. The use of algae as an antioxidant in bait was not very effective. The bait was quite developed right at the beginning of the storage experiment, so most likely the algae did not work properly. Vitamin C ice cream coating seemed to provide some protection, although vacuum packaging was most important. Many of the experiments that were carried out on the bait aimed to compare the bait with traditional baits made from the same material. Usually, less power was obtained from the bag bait, which can be traced in part to storage, but more problems are needed for storing bag bait than conventional bait. These experiments aim to test whether the bag bait has any repellent effect on fish approaching it. When interpreting the results, however, it must be borne in mind that raw material can be used in bag bait that cannot be used in traditional bait, better utilization of bait raw material is obtained and it is probably best for bag bait to be frozen in the sea. Towards the end of the project, fishing experiments indicated that bag bait yielded similar catches as traditional bait. During the last fishing trip in November 2006, haddock catches were better on bag bait than normal bait, but a flaw in the set-up of the experiment somewhat diminishes the veracity of the result. In addition, vitamin C-fortified bag bait gave slightly more catch than bag bait without vitamin C.

The aim of the project was to develop and produce effective bait for long line fishing from under-utilized raw material using newly developed snow technology that has been patented. The chemical composition of bait raw material and the use of seaweed as an antioxidant in the bait were studied and fishing experiments were done. In connection with the project a baiting machine was designed and produced. Experiments using the machine gave 97% of baited hooks. The use of seaweed as an antioxidant was not successful. The antioxidant activity of the seaweed was probably limited because the bait raw material was already oxidized in the beginning of the storage study. Icing the bait with vitamin C did give some protection although the most important factor seems to be the vacuum packaging. The aim of the fishing experiment was to study the attractiveness of the artificial bait. Most of the fishing experiments were done by studding the artificial bait against the traditional bait using the same raw material. The catch was often less from the artificial bait compared to traditional bait. This can possibly be explained by lower storage stability of the artificial bait due to oxidation. Using artificial bait mainly based on waste from fish processing plants and / or pelagic fish instead of expensive traditional bait material is however promising. The latest fishing experiments showed better results given similar catch for both the artificial and traditional bait. In the last experiment in November 2006 the haddock catch was better for the artificial bait that the traditional bait although it has to be mentioned that the experimental design was incomplete. Artificial bait with vitamin C added gave also better result than the artificial bait without vitamin C.

Electronic food information for consumers

Many believe that electronic markings will replace traditional bar codes in the coming years. Matís has recently years participated in a development project that aims to label fish tanks electronically. Such markings will increase the possibility of exploiting traceability and, among other things, enable companies to send electronic information to buyers about where the product is caught, where it has been processed and which way it has gone to market.

Demands from producers and consumers for an increased flow of information and better labeling of food are constantly increasing. It can be said that the development of electronic labeling for fish tanks is part of that development. For example, it is believed that electronic labeling will even make it possible for the refrigerator of the future to receive information and disseminate it to consumers, whether it is information about the last day of sale of food, the content of allergens or what side dishes apply to Icelandic cod. . It is also hoped that the refrigerators of the future will be able to communicate wirelessly with food manufacturers' databases, which will, for example, be able to warn consumers in the event of foodborne infections that may be related to the food in the refrigerator.

Experimental production of the refrigerators of the future has already begun, for example at Innovation Lab in Denmark. The company says that the refrigerators will be on general sale in 5-10 years.

The development of electronic labeling for fish tanks, which is funded by the AVS fund, is carried out in collaboration with FISK Seafood, Sæplast and Maritech. The results of the project are expected in the coming weeks.

Quality assessment of Matís

This week, Swedac and the Icelandic Patent Office carried out a quality audit of Matís' research methods, and such audits were carried out annually at IFL and the Environment Agency's Laboratory for many years.

The audit took place on 15.10. 2007 at Matís laboratory at Skúlagata 4 and on 18.10. In 2007, a similar audit was carried out at Matís' branch in Neskaupstaður. The Matís branch in Akureyri, on the other hand, carried out a quality audit in April this year.

According to Margrét Geirsdóttir, Matís 'quality manager, the audit went well and Matís' laboratory now has 27 accredited microbial methods and 7 chemical methods on its list. These are various microbiological studies on food, water, feed, environmental samples, medicinal products and substances, as well as specialized chemical measurements on food, water and environmental samples and measurements of pesticides in vegetables and fruit.

Accreditation is a recognition that a company has the best practices and has the technical ability to ensure that the measurements made there meet all international requirements in relation to the quality environment, work rules and strict quality control. The accreditation is based on the ISO 17025 standard on laboratory activities, but the provision on accreditation was introduced in an Icelandic regulation in 1994.

There are The Patent Office and Swedac, the Swedish Accreditation Agency, which grants the Matís accreditation. With an annual visit, the accreditation body examines whether the quality system and the measurement methods used in chemical and microbial research meet the obligations required for accreditation and described in the ISO 17025 standard.

In addition, the Matís laboratory is accredited by the New York State Department of Health for microbial measurements in bottled water.

It was haddock, charm!

Matís 'new report, which publishes a summary of the information available on Icelanders' consumption of the various fish species, states, among other things, that Icelanders prefer haddock to other fish. And probably few will be surprised!

The report is called "Fish consumption of 17 to 49 year old Icelanders in different fish species
and products
"And is part of the AVS project"Value and safety of Icelandic seafood - Risk composition and risk ranking”. According to the author of the report, Kolbrún Sveinsdóttir, the aim of the report is to make a detailed and accessible summary of the latest information available on Icelanders' fish consumption. Such information has not been available so far.

Among other things, the report states that fish consumption of older people is higher than that of younger people, and that the older age group also eats a wider variety of fish species and products than younger people. There also seems to be some difference between the fish consumption of the residents of the capital on the one hand and the people of the countryside on the other, both in terms of the frequency of fish consumption and the fish products that are eaten.

Fish is more often on the plates of people in the countryside and most often it is traditional products such as haddock, cod and salted fish and more often than not it is frozen products. Residents of the capital eat more fresh fish and semi-prepared fish dishes, which is undoubtedly due to better access to such a product than is available abroad. They are also more likely to eat fish outside the home than rural people.

Kolbrún says that the summary is mostly based on information obtained in the attitude and consumption survey of the AVS project "Attitudes and fish consumption of young people: Improving the image of seafood”Conducted in 2006, where more than 2000 people answered questions about their fish consumption and attitudes.

Kolbrún emphasizes the need for this type of information to cover all age groups and mentions, for example, that people over the age of 65 are considerably more vulnerable to various risk factors than others.
