Matís is researching the chemical form of arsenic in fishmeal and feed oil

Arsenic is a well-known toxic and carcinogenic substance and is therefore at the top of the US Agency for Toxic Substances and Disease Registry list of dangerous substances. The morphology of arsenic in food and other organic samples is important because the bioavailability and toxicity of arsenic are highly dependent on its chemical form.

Some arsenic chemicals, such as methylated trivalent arsenic, are highly toxic while arsenobetanide is safe. 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 in understanding the dangers of arsenic in our diet.

In the ecosystem, the substance arsenic is present 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. Until now, there has been limited information on different chemical forms of arsenic in, for example, fishmeal and fish oil. Matís has been involved in researching different chemical forms of arsenic in feedlots made from cod and capelin, and the results of these studies have recently been published in two scientific journals in peer-reviewed journals.

Research on the chemical forms of arsenic is very important in order to obtain data on which chemical forms of arsenic and in what quantities they are present in, for example, fishmeal and fish oil. This data can then be used as a basis for a review of laws and regulations on the limits of arsenic in the relevant seafood. Research in this field of research will continue at Matís, and Matís received a grant from AVS in 2008 to analyze the toxic and harmless chemical form of arsenic in fishmeal.

Further information on the results of Matís' above research can be found in Chemical Communication, 39, 2008 and Applied Chemistry, 47, 2008.

Matís holds the chairmanship of the European Sensory Network (ESN)

Emilía Martinsdóttir, Head of the Processing and Product Development Division, is currently chair of the European Sensory Network (ESN), an international association of research institutes and companies in the field of sensory evaluation and consumer research.

The ESN has 23 participants from 16 European countries, but there are also four non-European members of the organization: from Canada, South Africa, Australia and Israel.
This international organization was originally established as a forum for discussion and collaboration among the best research companies in each country and is intended to ensure the food industry in each country accessible and safe methods of sensory evaluation. Participants all have extensive experience in this field.

A meeting was held at the European Sensory Netwok in early October in Copenhagen. The meeting was well attended because in addition to ESN participants, there were representatives of 15 food companies that have been invited to participate directly in ESN-Industry Network Partnerships.

The companies will provide funding for specific research projects that they can agree on, and the research projects will be carried out by two or more ESN participants at a time. New research projects will then be selected annually. This ESN industry platform will increase the interaction of individual ESN members with the food industry.

The foreign food companies that have now signed an agreement to join ESN are Givaudan, Kraft Foods, Symrise, Firmenich, Nestlé, Unilever, Friesland Foods, Danone, Heineken, GlaxoSmithKlene, General Mills, Tetra Pak, Philip Morris and Danisco.

Promotion of local food production - Article by Matís employee in connection with MNÍ Food Day

The promotion of local foods aims to build a local and sustainable food economy. This includes food production, processing, distribution and consumption. It is believed that the development of local foods will strengthen the relevant places or areas economically, environmentally and socially. They also provide an opportunity for a closer connection between producers and consumers.

The meaning given to people in the concept of local foods varies. Usually, however, the definition includes the ideology that foods are of better quality and taste better because they are fresher and at the "best age" when they fall into the hands of consumers. Manufacturers also use materials or other methods to increase their shelf life, as these products have to travel less than traditional products available in stores. Another goal of local foods is to preserve and revive local food traditions, promote the cultivation of diverse crops to reduce the use of pesticides, fertilizers and waste generation. This will also strengthen local economies by strengthening small farms, local jobs and shops.

Food tourism is often associated with city trips, high-class restaurants and so-called "food countries". It is therefore a challenge to establish food tourism in rural Iceland. In recent years, several organizations have been established to promote the production and supply of local food, both nationwide and regionally.

There are three main organizations in the country; Directly from the farm, Lifandi landbúnaður and Matur-Saga-Menning, all of which aim to stimulate food culture in Iceland, among other things by strengthening the production of food from local ingredients and promoting the preservation of traditional production methods and cuisine. There has also been some revival in recent years among raw material producers and tourism operators in Iceland, about the importance of food in the tourist experience and the added value that is gained through the processing and sale of raw materials in the region. Stakeholders in many areas have partnered to work together to define and build food tourism and to support the production of local foods. Examples of such collaborations are Matur úr héraði, Matarkistan Skagafjörður, Þingeyska matarbúrið, Austurlamb, Suðurland taste the best and Ríki Vatnajökull. Preparations for such co-operation have also begun in West Iceland and the Westfjords. Today, therefore, the network, and the development of knowledge regarding opportunities in food tourism, has become quite dense. In addition to the support provided by such co-operation, work is now underway on the development of a comprehensive product development hotel in Hornafjörður. This is a systematic attempt to encourage innovation in small-scale food production in the country.

The Fisheries Exhibition 2008: great interest in Matís' booth

The Fisheries Exhibition 2008 took place in Fífan in Kópavogur 2.-4. October sl. There was a great demand for the show and it seems that each show is bigger than the one that came before. Matís took part now as last time and there was a lot of traffic in the company's booth. The highlights were when Ísfélag Vestmannaeyja offered live kúffisk on 3 and 4 October and when Einar Kristinn Guðfinnsson, Minister of Fisheries and Agriculture, visited Matís' exhibition area.

A large queue was created when the kúffisk was offered and the taste of the fish was well liked by those who tried it, as there was a lot of delicacy on the trip. The demand was so great that the exhibitors offered the roads much longer than originally planned.

The picture shows the Minister of Fisheries and Agriculture and Sjöfn Sigurgísladóttir, CEO of Matís, together with Siggeir Stefánsson, production manager at Ísfélagið, enjoying the shellfish.

Cod research in Vísindaport: Matís presents research

In the Science Report of the University Center of the Westfjords, on Friday 10 October, dr. Þorleifur Ágústsson, project manager at Matís, presents the company's cod farming research in Ísafjörður. The main focus of the research has been to prevent premature sexual maturation in cod by light control in sea cages.

Premature puberty causes the growth of cod to slow down, weight loss occurs as well as quality declines and declines. Matís has also worked on the design of sea cages for Icelandic conditions, developed a slaughter line for farmed cod and worked on research on the interaction of genetics and the environment on cod in farming. Special research facilities have been set up in Álftafjörður to conduct this biological and technical research.

The science report is an informal discussion time at noon on Fridays and starts punctually at 12.10. It discusses briefly, 20-30 minutes, about ongoing research or research that has been completed and then given the go-ahead. The science report takes place in the coffee hall of the University Center of the Westfjords and everyone is welcome.

Possibilities for the production of natural zooplankton for the first feeding of marine larvae

The overall goal of the project is to make an assessment of the possibilities of producing natural zooplankton for use in the early stages of aquaculture in Iceland. The quality and supply of larvae is one of the main problems in aquaculture today. The larvae of most marine fish need live prey when the pre-nutrition of the peritoneum is exhausted, in which case the supply of live feed animals is necessary until the larvae begin to absorb dry food. Domestic farms have primarily used rotifers and artemia that need to be bought from abroad and bred in the farms. There is a lack of the right composition of nutrients in these feed animals compared to zooplankton, which is the natural food of marine fish larvae, and research shows that the use of zooplankton provides increased yields and improved larval growth. The supply of natural zooplankton is seasonal, but the cultivation of various species has been tried in several parts of the world with good results. The results of research indicate that it is possible to cultivate various types of crayfish in sufficient quantities for production for juvenile farms. Many species of plankton are found in the marine ecosystem by the land that could be suitable for aquaculture, such as redfish, A. longiremis and Oithona spp. It is planned to apply for a research grant to the fund for the installation of facilities and experiments with the cultivation of selected species (s) of zooplankton.

The main goal of this project was to evaluate the potential for production of natural zooplankton for production of marine fish larvae in Iceland. Satisfactory quality and survival of larvae are one of the main problems in marine aquaculture. Marine larvae are fed live zooplankton during the first feeding stages, when the contents of the yolk sac are spent. Icelandic producers of marine fish larvae mainly use imported rotifers and Artemia as live feed. Copepods are the main food source of marine fish larvae in their natural environment and previous research indicate that the nutritional value of rotifers and Artemia is not adequate for successful development of the larvae. Successful growth and survival of larvae have been achieved using natural zooplankton. However, seasonal growth of natural zooplankton species prevents their use in commercial production of fish larvae. Copepods have been successfully cultured and there are indications that copepods can be cultured as feed in the production of marine fish larvae on a commercial scale. Various zooplankton species are found in the Icelandic marine ecosystem and that may be ideal candidates for culturing eg Calanus finmarchicus, A. longiremis and Oithona spp. As a next step, we will apply for funding of a larger project where the aim is to develop experimental facilities and carry out experimental cultures of selected species.

Lífríki í kalkríkum hverum á Ölkelduháls / Microbial ecology of calcium rich hot springs at Ölkelduháls geothermal area

The ecology of calcareous hot springs is little studied. This study involved analyzing the ecosystem in calcareous hot springs at Ölkelduháls and assessing whether it had a special position compared to the ecosystem of other hot springs in the same area with the same temperature and acidity. Bacteria were isolated from thermal samples by conventional culture methods. Genetic analysis methods were used to analyze the species composition. Many species found in samples from calcareous hot springs are also found in other hot springs. It is noteworthy, however, that species within the Aquificae party were not found in the samples, but they are very common in hot springs and widely prevalent. Elemental measurements showed differences in the concentration of sulfur, iron, carbon and arsenic in calcareous water and other hot springs, which may be an explanation for this. Cultivated methods identified mainly known bacterial species of the genera Thermus and Bacillus. One new species of the Meiothermus genus was isolated. Using genetic analysis methods, 195 true bacterial clones were obtained from calcareous hot springs, which were classified into 60 species based on 98% affinity. These 60 species are spread over nine camps. The species found in the samples were the same between the hot springs, but also unique to the sample from which they came. No ancient bacteria were found in the samples. Biodiversity in samples from calcareous hot springs at Ölkelduháls was slightly higher than comparable values from hot springs with similar properties in the same area. The high proportion of unknown species and genera in samples taken in calcareous hot springs at Ölkelduháls is noteworthy. Of the 60 species found in the samples, a sufficiently close relative of the same species was found in 25 cases. The other 35 species were so closely related to close relatives that they could not be classified except into genera, tribes, clans, or families. Ecosystems in calcareous hot springs at Ölkelduháls must therefore be considered very special.

The ecology of calcium rich hot springs is not well documented. In this study an attempt was made to estimate if microbial species composition in calcium rich hot springs in Ölkelduháls in Iceland was special compared to species composition in other hot springs with similar temperature and pH in the same geothermal area. Isolation methods as well as culture independent methods were used to analyze species composition in the samples. Many species found in the calcium rich hot springs are also found in other hot springs. It is noteworthy that Aquificae species were totally absent in samples from calcium rich hot springs, but these species were abundant and dominating in other hot spring samples. Elemental analysis of hot spring water revealed a difference in the concentration of sulfur, iron, carbon and arsenate between calcium rich hot springs and other hot springs in the area. Known species of Thermus and Bacillus genera were isolated from the samples. A novel Meiothermus species was isolated. Approximately 60 species belonging to nine phyla were identified in the samples using culture independent methods. The species identified in the calcium rich samples were identical between samples but also unique for the sample investigated. No archaea were detected in the samples. Biodiversity calculated for the samples from calcium rich hot springs was slightly higher than in samples from other hot springs. A high ratio of unknown species and genera in the samples from calcium rich hot springs in Ölkelduháls is remarkable. Of the total of 60 species identified only 25 had a close relative from the same species according to Genbank. The remaining 35 species were only distantly related to their closest relative and could only be classified to genera, families, orders or classes. Thus, the ecology of calcium rich hot springs appears to be quite unique.
