The West Nordic region has great opportunities for improved utilization, sustainability and increased value of organic resources. This report identifies the main organic resources in the area that are suitable for biorefining and the use of biotechnological tools. The report describes the valuable ingredients of the area's main biological resources, as well as the processing methods that are or can be applied to them and lists various end products that can be produced by further processing. The report provides an overview of the activities currently underway and the products produced in the area through finishing and biotechnology. Organic resources are divided according to whether they are by-products, originating in water or on land, or underutilized resources. Attention is paid to special opportunities and obstacles related to the West Nordic region.
The West Nordic region holds promising opportunities to improve utilization, sustainability and value from its biological resources. The region's major bioresources available for biorefining and biotechnological applications are the focus of this report. It identifies valuable ingredients in the different resources, processing technologies which are or may be applied, and possible end products obtained from further processing the raw material. An overview of the current operations and products which are being produced within the region is given. The report divides the available bioresources into biodegradable residues of aquatic or land origin and underutilized biomass. High-north specific opportunities and obstacles are highlighted.
A big party will now be held for all those who want to take part in Icelandic agriculture in the future in some way. Come, take part in Landsýn 2018 in Salurinn in Kópavogur, on Friday 23 February. There are really interesting lectures, good food and fun people to chat with, as can be seen in the program.
The emphasis will be on scientific results and their usefulness. Examples of where, when, how and why we should use sensory evaluation in product development, production and marketing will be examined. Professionals and scientists who work with sensory assessment, quality issues and consumer issues in the field of food get the opportunity to meet and compare their books.

The English name is: "Effects of packaging methods and storage temperature on the quality of Cobia (Rachycentron canadum) fillets during frozen storage"
The aim of this project was to study the quality and stability of cobia (Rachycentron canadum) fillets that were packaged in different ways and then stored in different conditions. On the one hand, the fillets were stored in open plastic bags, on the other hand in evacuated plastic bags. The fillets were then stored in a cold store for up to 5 months at -18 ° C and -25 ° C, respectively. Every month throughout the storage period, measurements were made of boiling efficiency, water content, nitrogen concentration in the total volatile nitrogenous base (TVB-N), phospholipids (PL), free fatty acid (FFA) formation and oxidation (PV and TBARS) to assess the effect of storage. on the quality of the cobia fillets.
The amount of phospholipids decreased significantly and the concentration of FFA increased during the storage period, which shows that enzyme activity was considerable in all experimental groups. There were significant changes in PV and TBARS values during storage. The choice of storage temperature and the length of storage had a significant effect on lipid degradation. The lipids were more stable at the lower storage temperature (-25 °). Furthermore, the results showed that the packing of cobia fillets in vacuum-packed packaging significantly reduced the oxidation or development of fillets compared to the air-packed fillets. Interestingly, cobia fillets in vacuum-packed containers stored at -18 ° C had a somewhat better quality compared to fillets in conventional packages stored at a lower temperature of -25 ° C.

The aim of the experiment was to investigate the possible flow of styrene from foam plastic boxes to fresh cod and redfish fillets, which are stored at typical temperatures during sea transport of fresh fillets from Iceland to Europe or America. US buyers want fish fillets to be packed in plastic bags before packing in a foam box due to possible styrene contamination from foam to fish. Therefore, in this project, styrene was measured in fish, which had been stored without plastic bags in foam boxes, and the amount of styrene was compared with the standards of the US Food and Drug Administration (FDA). A total of 12 foam boxes containing cod or redfish fillets were stored for 4, 7 or 13 days at either -1 ° C or 2 ° C, which corresponds to the optimal and highest probable temperature in fresh fillet shipping. One 10-50 g sample was taken from the lower part of the bottom fish fillet in each box and had thus been in direct contact with foam plastic and therefore placed in a glass bottle. Subsequently, the 12 samples were sent for analysis to Eurofins, an international laboratory in Germany. The results show that the amount of styrene, as well as other undesirable substances such as benzene and toluene, was below 0.01 mg / kg fish in all twelve fish samples. The FDA guideline (maximum) is 90 mg of styrene per kg of fish per person per day, which is equivalent to The result of this experiment is that the consumer has to consume 9000 kg of fish daily to meet the FDA standard, which is a very unrealistic amount.
The main conclusion of this experiment is that it is not necessary to pack fresh fish fillets in plastic bags for packing in foam boxes, which are stored and transported in refrigerated and supercooled conditions.

Björn Margeirsson, research director of Sæplast and Tempra and lecturer at the University of Iceland (bjornm@hi.is) and Sigurjón Arason, Matís' chief engineer and professor at the University of Iceland (sigurjar@hi.is).
In recent years, there has been a lack of funds to continue work on this monitoring project, and therefore this important data collection was suspended as well as the publication of results in the period 2013-2016. The project started again in March 2017, but due to a lack of funds, it now only covers the monitoring of undesirable substances in edible parts of seafood from the resource intended for human consumption, and not fishmeal and fish oil for feed. For the same reason, no chemical analyzes were performed on PAH, PBDE and PFC substances this time.
The aim of the project is to demonstrate the position 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 monitoring and review is constantly necessary.
In general, the results obtained in 2017 were in line with previous results from 2003 to 2012. The results showed that Icelandic seafood contains an insignificant amount of persistent organic pollutants such as dioxins, PCBs and pesticides.
EU maximum levels for dioxins and dioxin-like PCBs (DL-PCBs) in food and feed were lowered on 1 January 2012 (EU Regulation No. 1259/2011) and maximum levels were set for "non-dioxin-like" PCBs (NDL-PCBs) for the first time ). The new maximum values are used in this report to assess how Icelandic seafood meets EU requirements. The results for 2017 show that despite the change in maximum levels for dioxins, DL-PCBs and NDL-PCBs, all samples of marine products for human consumption are below the EU maximum levels for persistent organic pollutants and heavy metals. The concentration of so-called ICES6-PCBs was found to be low in the edible part of fish, compared to the new maximum EU values. The results also showed that the concentration of heavy metals, such as cadmium (Cd), lead (Pb) and mercury (Hg) in Icelandic seafood was always below the EU maximum values.
High-quality and well-defined scientific data on undesirable substances in Icelandic seafood is a key factor in demonstrating the status of Icelandic seafood, e.g. safety and health. The export of Icelandic food depends on being able to demonstrate their safety, taking into account laws, regulations and market requirements. Scientific data from independent researchers is also important in market presentations of seafood for potential buyers and strengthens all marketing work for Icelandic seafood. The data are also used for risk assessment of food and to influence the setting of maximum levels for contaminants in food.
