Research of superchilling of whitefish / Research of superchilling of whitefish

Five studies were conducted by a research team (supercooling team) in the summer of 2014 to test the effect of supercooling on the processing and product quality of whitefish. This project was based on foreign scientific research on supercooling, which was carried out in laboratories, while the research of the supercooling team was carried out under processing conditions. The results of the research team indicate even more activity than the basic research on which it was based. The main drawbacks were that with supercooling immediately after bleeding and gutting, death stiffness can be significantly delayed, but no damage processes begin until it is completed. It is known that the main reasons for release are rapid death stiffness as the flesh tears with a rapid contraction that clashes with the fish's bone marrow. Fish is 800 times more sensitive than meat and therefore it can withstand very little damage during handling. The results of the supercooling team's research show that during supercooling, the flesh hardens without freezing and withstands all treatments much better, such as filleting, peeling and trimming. Not only is there a difference in the appearance of super-chilled fillets compared to traditional ones, but the proportion of those who went for the most expensive packages was significantly higher. An experiment was carried out at Íslandssaga in Suðureyri and the result was that the increased value due to supercooling was around ISK 900,000 per day. When processing super-chilled fillets for fresh fish export, they were returned in packages at -0.8 ° C while traditional processing was at +2 to + 5 ° C. Freezing part of water in fillets (5‐30%) builds up a high cooling energy that maintains a low temperature throughout the processing (filleting, skinning and trimming). The results of the research team are that with supercooling on board a fishing vessel down to -1 ° C immediately after bleeding and gutting, the use of ice becomes unnecessary for storage in trains and warehouses on land. Trains and cold rooms will be operated at 11 ° C, which is sufficient to maintain supercooling for a long time. Attempts were made to store cod under these conditions for eight days, and the results of research showed that its quality during processing at Fisk Seafood was high and better than with traditional processing.

Five studies were conducted by a research team (superchill ‐ team) in the summer of 2014 to test the effects of superchilling on production and quality of whitefish. This project was based on published studies on superchilling, conducted in laboratories, but the superchill ‐ team conducted their study at industrialized conditions. Conclusion of the research team suggests greater functionality than the scientific researches it was based on. The main conclusion are that super ‐ chilling right after bleeding and gutting can significantly delay rigor mortis, but no spoilage take place before that process. It is well known that the main reasons for gaping in fish fillets are the contraction and relics causing by rigor mortis. Fish is 800 times more sensitive than meat, so it is perishables against handling in processing lines, like filleting, skinning and trimming. One finding in these research is that by super chilling the fish before the process, the flesh is more stiff without being frozen, and can withstand handling in processing much better. The super chilled product is not only looking better compared to the traditional product, but the proportion of more valuable products were significantly higher. A research made in the freezing plant Icelandic Saga in Sudureyri, gave a result were increased value due to super cooling was about 900 thousand ISK per day. In the same trial a temperature for fresh packed fillets for the British market, the product temp for super chill were ‐0,8 ° C, but the traditional product were packed at +2 to +5 ° C. Freezing part of the water content of the fish, around 5‐30%, builds up a massive cooling energy that keeps low temperatures throughout the processing (filleting, skinning and trimming). Results of the research team were thatsuper ‐ cooling fish on board a fishing vessel, down to ‐1 ° C immediately after bleeding and gutting make the use of ice in fish hold redundant. The fish hold need to be run at ‐1 ° C which is sufficient to maintain the super ‐ cooling for a long time. The research team kept whole cod without ice for eight daysin container and ‐1 ° C, with demanding result and extremely good product quality, significantly better than the traditional process.

Icelanders' utilization of cod attracts attention at the FAO

In a recent publication of the FAO (Food and Agriculture Organization of the United Nations) entitled The State of World Fisheries and Aquaculture (SOFIA) confirms that Iceland is one of the main fishing nations in the world.

The publication publishes a list of the 18 nations that caught the most fish in 2012. At the top of the list is China with 13,869,604 tonnes caught. Next comes Indonesia with 5,420,247 tons and in third place is the United States with 5,107,559 tons. Iceland is in 17th place on the list with a total of 1,449,452 tonnes of fish. Only one other European country is on the list, Norway, which ranks 11th with 2,149,802 tonnes caught in 2012.

Icelanders are leaders in innovation

The publication also focuses on the importance of fish traceability with the aim of promoting food security and preventing food fraud. There are studies by Icelanders that Matís has been involved in, mentioned as examples of successful projects of this kind. It is also considered that it is not possible to trace the origin of fish on the European market in 25 - 50% cases.

Icelanders' full utilization of cod is also a topic of discussion in the publication, which discusses the possibilities of using fish by - products for human consumption. It is stated that Icelanders exported 11,540 tonnes of dried cod heads to Africa in 2011. It is reported that in addition to heads, the roe and liver are used for human consumption, but the rest is mostly used for feed.

The publication in question is the largest edition of the FAO and is published every two years. The aim of the publication is to provide strategic and public bodies as well as those who need to rely on the fishing industry with comprehensive and impartial information on the global situation and to provide ideas on how to respond to existing challenges. Here you can read the latest version of SOFIA.

Traceability results in higher product prices

Food traceability requirements are increasing day by day, whether meat, fish, vegetables or fruit. Matís is currently working on projects that will be useful for traceability registration and thus ensure that the origin and processing process of food on the market can be confirmed. At first, the spotlight is on fish products.

There has been a great deal of awareness in recent years about the importance of knowing the origin and processing processes of the foods that come on the market. This applies not least to the markets to which Icelanders export the most fish.

Matís is currently working on three projects related to the importance of fish traceability and prevention against fraud in the food industry.

In connection with the WhiteFish project, a standard has been developed that enables companies to record and manage information on the environmental impact of their production. But by being able to demonstrate the environmental impact of the product and break it down into batches, the results of the project will be used to create producers of cod and haddock products the opportunity to differentiate themselves in markets where the environmental impact of fishing, processing and transport is important.

In the project WhiteFishMall has been working on researching what information can be used to increase sales of fish products from the North Atlantic. Market research has shown that consumers in the UK want better information about where the fish comes from, whether it is caught in an environmentally friendly way, whether the stocks are self-sufficient, nutritional content and the positive positive effects of fish consumption on health, recipes and so on. To meet these consumer requirements, the WhitFishMall project has designed a web solution that can meet these requirements. The look, layout, data revenue and data management have been verified in several value chains and the salary has been tested in several stores in the UK.

The project Food Integrity or Food Integrity, launched in early 2014, aims to leverage research to ensure the integrity of European food and develop methods to detect and prevent fraud in the European food industry.

Proper handling and storage throughout the production process is the basis for the food to be fit for human consumption, but in the production of food the question always arises about the safety of the food towards the consumer, as a result the requirements for hygiene, good production and traceability have increased enormously. come to the food value chain.

Conference on marine settlements, small boat fishing and rural development in the North Atlantic

In connection with the Icelandic Fisheries Exhibition, which will take place in Kópavogur at the end of September, an international conference will be held to discuss the state of coastal settlements, small boat fishing and rural development in the North Atlantic.

Communities in coastal areas and small boating are closely linked in the countries bordering the North Atlantic. In most parts of the area, the sea settlements are under attack and small boat companies are in operational difficulties, as well as the renewal of the industry is limited. These challenges, along with other issues, will be discussed at the conference and seek to analyze the future potential of the North Atlantic coastal communities.

The conference is structured in such a way that representatives from Iceland, Norway, Sweden, Denmark, the Faroe Islands, Greenland and Newfoundland will first give short lectures on the state of these issues in their countries. A research project will also be presented where the performance and wages of small boat companies in Norway, Sweden, Denmark and Iceland are analyzed and compared with other industries. The Icelandic owners of small boat fishing in Norway will report on the operating environment of small boats in Norway, and compare it with Iceland; and finally, the chairman of the board of Byggðarstofnun will report on the work and policy of the institution, but Byggðastofnun has recently reviewed the institution's methodology to perform its role better.

The conference will take place in Smárinn (meeting room on the upper floor of a building that connects Smárinn and Fífun) on Saturday 27 September at 10: 15-14: 00. The conference is held in English, admission is free and open to all, but people are asked to register by sending an email to jonas@matis.is.

Icelandic fisheries: better data - more value!

All decisions, large and small, are made on the basis of information and knowledge, so one would think that one of the nation's most important industries would be full of data that could be relied on. When looking for answers to many pressing questions about development and value creation in the Icelandic fisheries sector, it often becomes clear that information is not available or that it does not stand up to scrutiny.

Now it is not the case that it is not possible to draw the big picture, the catch of all species is a known size and the total export value is also available, but when assessing, for example, the development and innovation of individual species or products, it is often more difficult.

Great emphasis has been placed on registering all catches and this is of course closely monitored, but when it comes to exports, another system based on the registration of exports according to customs register numbers takes over.

The Customs Tariff is intended to be the system that is to cover all products transported to and from the country. The system used in Iceland is based on a harmonized international numbering and classification system that is used by over 200 nations, so that basically cod with the same number is used in most parts of the world. This applies to the first six digits, then nations can extend the number and add a detailed product analysis. In Iceland, it has only been possible to add two digits due to the limited capacity of databases in use.

The information that exporters place on export papers and return to Customs is then the basis for the publication of data at Statistics Iceland, so that if exporters are throwing their hand in the provision of information, the information published by Statistics Iceland will be less noticeable. As exports are not the subject of fees in this country, it is obvious that control of the correct registration is limited, it does not really take place until in the country of import because then the product must be linked to the correct customs number of that country.

When looking at export figures, the first stop is to look at the product description and find out what is meant or what is not meant, it can be very difficult to get a clear picture of the products listed in certain tariff codes. Product descriptions are often very open and can refer to different products, but over 100 terms are used to describe seafood in the Customs Tariff and there are no further explanations for these terms.

It is possible to pick up many examples of contradictory product descriptions and it is clear that there is a lack of product knowledge when compiling them, but it must be borne in mind that the Customs employees have various other things on their plate than compiling product descriptions for seafood. Customs register numbers for seafood are just a few hundred, while the customs register as a whole contains thousands of other product descriptions, so it is important that the seafood industry is involved when planning such an important database.

It is the fisheries industry that benefits first and foremost from good and detailed information on how to succeed in value creation and utilization of seafood, because in the information the opportunities will be visible.

Despite a considerable revision of the 2012 tariff schedule and an increase in the number of numbers, it is by no means possible to identify in any way the utilization of individual species, which can be seen in the fact that the fourth most valuable species imported from Iceland is "other fish" or "various species". are products where no specific fish species is mentioned in the product description. This "other fish" yields about 10% of the total value of exported marine products.

There are affirmations about such and such great utilization of individual species and people are beating their chests and claiming that we are superior to other nations. But it is not possible to say anything like that unless there is better information about all the products. While different products are collected in individual customs register numbers, it is not possible to calculate back and say what the utilization of the catch is.

Those who have come close to processing seafood know that it is important to know whether fish is with or without head, gutted or ungutted, fillets with red and bone or skinless and boneless, etc., if this information is not available then it is impossible to calculate out the total utilization of individual species.

Matís has been in a collaborative project with the Directorate of Customs, Statistics Iceland, the Association of Fish Processing Plants, the National Association of Fish Farms, Icelandic and Iceland Seafood, where these issues have been reviewed. The project was funded by the AVS Fund. The report "Increasing the value of data" can be found here (best viewed in Acrobat Reader).

The result of the project is a summary of what the situation is and how the current information system is not getting a good enough handle of this data that is being created. There is also a proposal for improvements and how very detailed information could be obtained on all types, values and utilization, but in order to achieve this, product descriptions must be harmonized and it must be ensured that there is the same understanding of the terms used. There are now definitions for the product descriptions and they have a number of pictures to better show what is meant.

This new proposal will simplify all registration and can in fact make the preparation of special Icelandic tariff codes for seafood completely unnecessary, but still offer much more detailed information.

It will then be possible to answer almost all possible questions regarding value creation and utilization of seafood, and thereby make sensible decisions, based on the best available information, on everything related to the utilization of the resource.
