Values from by-products of slaughter and meat processing - Report for 2009

The project is about making value from by-products of slaughter and meat processing. The technical goal was to adapt and develop processing methods that transform by-products from cheap human food, feed and waste into expensive special products that will be sold to customers in other countries. The aim of research and education was to participate in and strengthen cluster collaboration and promote the training of young scientists. The project is for two years. This is a report on the previous years of the project, during which research and development projects were carried out on products from the intestines and rumen, improving the utilization of blood and offal. Freeze-drying of organs for drug and biochemical production also began.

The project is about creating more value from slaughter and meat processing by ‐ products. The technical aim is to adapt and develop processes to convert by ‐ products from being low value food, feed and waste to high value products for export. The aim is also to train young scientists by allowing them to take part in the project. This is a status report from the first year of the project. The project included:

- Development of casing processes

- Better utilization of organs and bloods

- Freeze drying of products for biotechnological development

Nutrient value of seafood - Proximates, minerals, trace elements and fatty acids in products

Measurements were made of the main substances (protein, fat, ash and water), minerals (Na, K, P, Mg, Ca) and trace elements (Se, Fe, Cu, Zn, Hg) in the main types of marine products prepared on the market. These included fish fillets, roe, shrimp, lobster and various processed products. Measurements were made of fatty acids, iodine and three vitamins in selected samples. Several products were chemically analyzed both raw and cooked. The aim of the project was to remedy the lack of data on Icelandic seafood and make it accessible to consumers, producers and retailers of Icelandic seafood. The information is available in the Icelandic database on the chemical content of food on Matís' website. Selenium was generally high in the marine products studied (33-50 µg / 100g) and it is clear that marine products can play a key role in satisfying people's selenium needs. The fatty acid composition varied according to the types of seafood and there were special characteristics that can be used as indicators of the origin of the fat. The majority of polyunsaturated fatty acids in seafood were long-chain omega-3 fatty acids. The amount of minerals was very variable in seafood and there are changes in the concentration of these substances in processing and cooking. There was little loss of the trace elements selenium, iron, copper and zinc during cooking. Measurements were made on both selenium and mercury as selenium counteracts the toxicity of mercury and mercury is one of the undesirable substances in marine products. In all cases, mercury proved to be well below the maximum levels in the regulation. Roe and roe products had the special feature of containing very much selenium but also very little mercury.

Proximates (protein, fat, ash and water), minerals (Na, K, P, Mg, Ca) and trace elements (Se, Fe, Cu, Zn, Hg) were analyzed in the most important Icelandic seafoods ready to be sent to market. The samples were fish fillets, roe, shrimp, lobster, and several processed seafoods. Fatty acids, iodine, and three vitamins were analyzed in selected seafoods. A few seafoods were analyzed both raw and cooked. The aim of the study was to collect information on the nutrient composition of seafood products and make this information available to consumers, producers and seafood dealers. The information is available in the Icelandic Food Composition Database. Selenium levels were generally high in the seafoods studied (33‐50 µg / 100g) and seafoods can be an important source of selenium in the diet. Fatty acid composition was variable depending on species and certain characteristics can be used to indicate the fat source. Polyunsaturated fatty acids were mainly long chain omega ‐ 3 fatty acids. The concentration of minerals was variable, depending on processing and cooking. Small losses were found for selenium, iron, copper and zinc during boiling. Both selenium and mercury were analyzed since selenium protects against mercury toxicity and data are needed for mercury. Mercury in all samples was below the maximum limit set by regulation. Roe and lumpsucker products had the special status of high selenium levels and very low mercury levels.

The status of pollution of heavy metals and other toxins in the sea around the country - a new report by Matís

Pollution of heavy metals and other toxins in the sea around the country is generally well below international standards, as stated in Matís' new report on changes in the marine environment around the country (here)

The concentration of cadmium in Icelandic mussels, however, is higher than is generally the case in mussels from the waters of Europe and America.

Since 1989, an annual monitoring project of pollutants in the marine environment of Iceland has been underway. The project is funded by the Ministry of the Environment, the Ministry of Fisheries and Agriculture and Matís ohf. The Environment Agency is the administrator of the project.

Various pollutants in the ocean can enter marine organisms or organisms that feed on seafood. In many cases, this pollution is man-made and there is growing concern about this development. Pollutants are transported by air and sea currents from mainland Europe and America as well as pollution from Iceland. It is therefore important to monitor the amount of pollutants in Iceland, both in the environment and in the organisms that live in the country. It is also important to be able to compare the state of the marine life around Iceland with the situation in other countries, not least because of the importance of marine products to the nation.

In the Matís report (report 24-11 on the Matís website) the results of the monitoring project for the years 2009 and 2010 are published. trans-nonachlor, toxaphen, DDT and PBDE. The aim of the monitoring project is to identify changes that may occur in the concentration of trace elements in the marine environment around the country during a certain period and between different ocean and coastal areas. Among other things, the research is important for the sale of Icelandic seafood in both domestic and foreign markets, where it can be demonstrated with scientific data that Icelandic fish is caught in an unpolluted environment.

The report states that the concentration of heavy metals such as mercury is very low. However, the concentration of cadmium has sometimes been higher in the marine environment in Iceland than in more southerly areas. However, the amount of cadmium is low in the organisms studied, for example in the range of 0.1-1 mg / kg in mussels. The high concentration of cadmium in Iceland is regional and is considered to have natural causes as there is no evidence of man-made cadmium pollution. The results show changes in the pattern of chlorine organic matter in mussels collected near Hvalstöðin in Hvalfjörður in September 2009, there were no visible changes in the concentration of these substances at the mussel collection site at Hvammsvík in Hvalfjörður or at any other collection site around the country studied in 2009. Important is monitoring these changes in the pattern of concentration of chlorinated organic substances in mussels in the monitoring project in the coming years to see if they are still present. A detailed statistical analysis of the data is in progress, i.e. Scientific methods can be used to estimate the increase or decrease of pollutants in the marine environment in Iceland.

Sjávarskyr? Icelanders get to taste first!

Will a new Icelandic skyrocketing product win an award at Ecotrophelia Europe, as the most promising and eco-friendly innovation idea in the food sector in 2011?

In collaboration with Matís, Nýsköpunarmiðstöð Íslands and other parties, Jón Trausti Kárason, Kjartan Trauner, Jökull Vilhjálmsson and Andri Freyr Þórðarson have developed a product that won the Icelandic Ecotrophelia competition and they are therefore on their way to the big competition which takes place in Cologne 9th and 10 October next.

The product in question is skyr, which contains kelp of the type Marínkjarn from Breiðafjörður, but the kelp was the starting point in the conceptual work of the product development.

In addition to Marínkjarnan, the product contains organic milk from BioBú, Icelandic blueberries, organic flower honey and furthermore it contains no added sugar or additives!

We all know about the benefits of skyr consumption. With the raw materials that are now added to the skyr, the product acquires a completely new loyalty image. The antioxidant properties of blueberries are well known and kelp also contains lots of vitamins and minerals as well as a wide range of antioxidants. The organic flower honey gives the product such a moderately sweet taste.

The sky will be introduced and people can taste it at the Fisheries Exhibition in Kópavogur on Saturday 24 September, at 13-15.

Do not miss this opportunity!

EcoFishMan meets with stakeholders in Copenhagen

Matís manages the European project EcoFishMan, which aims to develop new methodologies that will be useful in reforming the European Union's fisheries management system.

The project is interdisciplinary and uses information on the ecological, social, economic and managerial aspects of fisheries management, but the aim of the project is to enable people to assess and respond to the aforementioned aspects in the implementation of fisheries management. Great emphasis is placed on collaboration with stakeholders at all stages of the project, and as part of that process, participants in the project met with stakeholders from fisheries, processing, research institutes, consumer organizations and environmental organizations across Europe on 8 September. The meeting took place in Copenhagen and the project was presented to the stakeholders and a contribution from them was sought for further work. EcoFishMan participants gave a talk to explain the various aspects of the project and then there was a discussion about the talk. In EcoFisMan, four different fishing systems will be used as case studies in the development of the system, ie. Icelandic demersal fisheries, Portuguese bottom trawling for crustaceans, demersal trawling in the North Sea and demersal trawling in the Mediterranean. 

Further information about the project can be found on Matís' website (EcoFishMan) and on the project's website, EU_EcoFishMan.

Quality of coastal fishing catches 2011

The summer of 2011 was the third summer in which free hand fishing with restrictions on the total amount, so-called coastal fishing, was allowed. The pot contained 8,500 tons and a total of 685 boats took part in the fishing.

The quality of coastal fishing catches has been somewhat discussed in recent months, and therefore the Ministry of Fisheries and Agriculture requested from Matís, Matvælastofnun and the Directorate of Fisheries that an assessment be made of the quality of coastal fishing catches. Various documents were collected during the implementation of the audit, including:

  • Measurements of catch temperature when landing across the country, a total of about 2,500 measurements.
  • Measurements of the fish markets at the temperature of the catch this summer, a total of about 10,000 measurements.
  • Field surveys, i.e. 405 coastal fishing boats were boarded to investigate various issues related to the handling of catches.
  • Interviews with the parties that handle the catch of coastal fishing boats the most, ie. buyers, sellers, fish markets, gutting services, carriers, fish processors, etc. a total of about 30 people.
  • Visits to fish markets around the country to check procedures, in addition to discussions with representatives of fish markets.

The results of the survey show that inshore fish are of very different quality. Coastal fishing boats fish during the hottest season when the fish are in a bad state due to natural causes, they often stay close to land where the fish are small, there are more worms and the color of the red is darker (so-called kelp); they usually land uncut catches and the size distribution is large. Access to ice is limited in some ports, gutting services are generally no longer available and the transport of ungutted catch between parts of the country at this time of year can be detrimental to the raw material if the catch treatment has not been satisfactory. It is therefore a problem for the coastal fishing fleet to ensure the quality of the catch and it is especially important that the catch treatment is exemplary.

The survey reviews the issues that most affect the quality of the catch, examines how the coastal fishing catch came out this summer regarding those issues in comparison with other day-trippers and finally puts forward proposals on how to promote improvements.

The most influential factor in the quality of inshore fishing is cooling. In general, it can be said that the coastal fishing fleet performs well in comparison with the traditional day-trip boats in terms of cooling, and it is not possible to distinguish a significant difference between these fishing groups. The results of the audit also indicate that the cooling of coastal fishing catches has improved significantly from the previous year. It should be noted, however, that there is a need to further improve cooling, both for coastal fishing boats and other day-trip boats, in order to meet the requirements set out in regulations, ie. that the catch temperature is below 4 ° C within 6 hours. after fishing.

Bleeding facilities are limited on board inshore fishing boats, ie. the catch is usually bled into ice or sludge in the tanks in which it lands. However, as hand-held fish are usually very active when they are hauled on board, blood emptying is better than otherwise, and buyers are usually satisfied with the bleeding of the catch. Representatives of the fish markets say that they have never received a complaint about poor bleeding and therefore it can be concluded that bleeding is not a significant problem with the coastal fishing fleet.

Classification and gutting are also factors that affect the quality of coastal fishing catches. It is important that fish markets and their customers find acceptable ways to ensure that buyers are allowed to deliver the size of fish they think they are buying, but it has been widely reported this summer that buyers have been dissatisfied with the size classification. However, this is a problem that is particularly related to distance selling, as it can be difficult to provide information on the classification of catches that have not yet been landed. Cutting of day-trippers' catches has also been a problem this summer, and it is recommended that the authorities consider changes to the regulations on gutting before the start of the next coastal fishing season.

With regard to other factors that affect the quality of coastal fishing catches, it is most natural that market laws should prevail, ie. that price and quality go hand in hand, but in order for that to happen, it is necessary to increase the visibility of quality factors in the fish markets and increase promotion. The arrangement of coastal fishing, ie. Olympic fishing, can contribute to the pursuit of lower quality catches and therefore it is important to promote education for fishermen, as well as others in the value chain. Efforts were made in education, measurements and monitoring of day rowing boats in the summer of 2011 and it is clear that this has had some success. It is therefore important that the government ensures that this path is continued next year.

We're on the right track, but it's better if it's enough!
