Bacteria destroyed by high pressure treatment

Matís (Matvælarannsóknir Íslands) has succeeded in developing a method that kills bacteria in infected salmon in a short time. The high-pressure treatment method ensures safer salmon consumption and longer shelf life without adversely affecting color and texture. This is a new approach to hypertension treatment, which was developed in Germany a few years ago. With new technology, you can achieve the required results in less than 10 seconds instead of the previous 15 minutes.

With the new method, the bacterium Listeria can be eliminated in smoked salmon. Listeria is extremely rare in salmon but can cause infections in consumers who eat salmon that contains the bacterium.

The results of Matís' research show that high blood pressure needs to be 700-900 MPa to kill the bacterium. Hypertension has a small effect on the structure, color and texture of a product. The method can provide consumers with smoked salmon that has a longer shelf life and is free of Listeria and even free of other bacteria. Knowledge benefits will lead to further development and new uses of this new technology.

Traditional cold smoking of salmon is not enough to kill Listeria and can therefore be a problem for both producers and consumers. However, with improved hygiene and improved quality control, good results have been achieved, but to ensure that smoked salmon does not contain the bacteria, it is necessary to develop new technologies such as hypertension. Participants in the project were from Matís (formerly the Fisheries Research Institute and Keldnaholt Food Research).

Reykjagarður chooses Matís

Reykjagarður, the producer of Holta chicken, has signed a one-year contract with Matís (Matvælarannsóknir Íslands) for measurements of samples for the company's safety and quality control. These are mandatory measurements of Salmonella and Campylobacter in faecal samples from poultry farms. Samples will also be collected from other farms that have poultry slaughtered at Reykjagarður.

Reykjagarður sells Holta's products to retail chains, restaurants, fast food restaurants and canteens.

Samples from Reykjagarður will be examined at Matís' Food Safety Division. The main research projects of the Food Safety Division are in the field of microbiological and chemical research on food, feed and the environment. Microbial studies cover most of the most important pathogens that can be found in food. The Department of Food Safety is systematically working to increase collaboration with foreign research institutes and companies through international research and development projects.

"Matís laboratories are certified and can provide services in a wide range of microbiological and chemical measurements. The company focuses on efficient and reliable service and provides customers with favorable service contracts where the scope of the agreed projects is especially taken into account," says Franklín Georgsson, Matís' Food Division Division Manager.

Dried fish as health food

One of the main goals of the project was to obtain basic information about the properties of Icelandic dried fish and that the information would be open and thus for the benefit of all dried fish producers in Iceland. The main conclusion of the project is that dried fish is a very rich protein source with 80-85% protein content. The amino acids were measured and compared with amino acids in eggs. The result is that dried fish proteins are of high quality. These results support the marketing of dried fish as both a healthy food and a national food. It is important to look at the salt content in dried fish better and try to reduce it to increase the health of dried fish, especially in hot-dried dried fish, as it was much higher than in other dried fish. Measurements of trace elements showed that their amount in dried fish is well within limits compared to the recommended daily allowance (RDS) except in selenium. Its amount in 100 g is three times the recommended daily dose. However, it is not considered harmful in any way.

The main object of this project was to provide information of the quality in Icelandic dried fish to be of benefit for all producers in Iceland. The main results showed that dried fish was a very rich source of proteins, containing 80-85% protein. Amino acids were measured and compared to the amino acids in eggs. It was concluded that the proteins in the dried fish were of high quality. This supports the marketing of dried fish in the health foods and traditional food markets. It is important to better analyze the salt content in dried fish and reduce it to improve balanced diet in dried fish, especially for indoor produced dried fish, which salt content is rather high. The trace elements in dried fish showed minimal content, except for selen where the content was threefold the recommended daily allowance (RDA). This is not hazardous for people in any way.

Fish consumption of 17 to 49 year old Icelanders on different fish species and products

This report is part of the AVS project "Value and safety of Icelandic seafood - Risk composition and risk ranking". Its aim is to provide a detailed and accessible summary of the information available on Icelanders' fish consumption, and is based on information obtained in the AVS attitude and consumption survey of the project "Attitudes and fish consumption of young people: Improving the image of seafood" conducted in 2006. A national sample of people aged 17-49 was obtained from Statistics Iceland and a total of 2198 responses were received. The results concerning the total frequency of fish consumption, the frequency of consumption of fish species and products, the relative consumption of fatty and lean fish species were examined in terms of age, sex and place of residence. People's attitudes towards the health and risk of fish consumption were also examined. Although people generally seem well-informed and convinced of the health and safety of seafood, fish consumption is lower than recommended. People in the oldest age group (40-49 years) eat fish 1.9 times a week on average, but fish consumption is lower in the youngest age group (17-29 years) or 1.3 times a week. Icelanders eat the most lean fish such as haddock and cod, and it can be estimated that the 50% fish we eat are lean, about 25% medium fat and about 20% fatty fish such as salmon, trout and herring. Consumption of packaged, prepared fish dishes, chilled and frozen was insignificant and less than 10% people eat these dishes once a month or more. However, 30% people eat semi-prepared chilled fish dishes from a fresh fish table once a month or more. There were some differences in the consumption of different fish species and products according to age. The choice of younger people is not as diverse as that of older people, and younger people often do not eat fish species and products that older people have become accustomed to, such as marinated herring and caviar. A large part of the youngest age group eats fast food twice a week or more often. There is a considerable difference in people's consumption according to place of residence. People in the capital area eat fish less often, people in the countryside eat more traditional fish species such as haddock, but far more often frozen fish and salted fish. Residents of the capital, on the other hand, more often eat semi-prepared fish dishes from a fresh fish table.

The beneficial effects of fish on health are well known. Access to accurate information about fish consumption, fish species and -products, the percentage of lean vs fat fish species is very important in order to estimate the value and safety of Icelandic seafood products. This report is a part of the project Food safety and added value of Icelandic seafood products, funded by the AVS Fund of the Ministry of Fisheries in Iceland. The aim of this report is to provide detailed overview of the available information on fish consumption in Iceland. The information was collected in the project Young consumer attitudes and fish consumption: Improved image of seafood, an attitude and consumption survey in 2006 which was funded by AVS. A representative sample of the population in Iceland was provided by Statistics Iceland and answers from 2198 people 17-49 years were received. Results concerning total fish consumption frequency, fish species and -products, the relative consumption of fat vs lean fish species, attitudes towards the wholesomeness and risks of fish consumption were analyzed with regard to age, gender and residence. Although, people are generally well informed and convinced that seafood is wholesome and safe, fish consumption is below recommendations. People in the oldest age group (40-49 years) consume fish 1.9 times per week on average, but the youngest age group (17-29 years) consumes even less fish, only 1.3 times per week. Lean fish species, such as haddock and cod, is the most popular and it can be estimated that more than half of the fish consumed is lean, approx. 25% medium fat species but only 20% fat fish species such as salmon, trout and herring. Consumption of packed fish meals, chilled and frozen, is very low, less than 10% consume such products once a month or more frequently. However, 30% consume chilled ready-to-cook fish meals bought from fishmongers or fresh fish counters at supermarkets. Differences in consumption of fish species and -products were observed with age, the preferences of younger people tended to be more limited range and they often did not consume some of the fish species and -products which older people were accustomed to, such as marinated herring and caviar. Differences in consumption were also observed depending on residence. People in the capital area are likely to consume fish less frequently, whilst people living in the countryside are more inclined to prefer traditional fish species such as haddock, but much more often frozen- and salted fish.

Solutions due to environmental impact during stroke release

In recent years and decades, satisfactory solutions to sludge discharge have been sought. Considerable emphasis has been placed on finding ways to process the slug into usable products that could be sold. This work has mainly been done by individuals, organizations and institutions. In this connection, one can mention plans for digestion from slag to feed production, but these experiments were well under way in the mid-1980s. It can be said that the problem with slag processing is twofold. The slag is damaged very quickly, which makes it difficult to use it in certain products. Secondly, the transport cost is high compared to the value of the product made from slag. The way in which slag is discharged varies greatly from one situation to another, but the growing emphasis on environmental issues in recent years has fueled old ideas about the utilization of slag.

In recent years, a considerable effort has been made to ensure a proper disposal of viscera from fish processing. The emphasis has been on processes that could return a marketable product. In the late 20th Century a lot of this work was focused on silage production. There are mainly two major problems with regard to the processing of viscera: Firstly, viscera spoils very rapidly, which makes it difficult to use in many products. Secondly, the cost of transportation is very high compared to the value of the products processed from viscera. Handling of viscera is very diverse in different places but increased emphasis on environmental issues has raised the issue of utilization again.

Pork: More accurate results with electronic evaluation

The preconditions have now been created for the introduction of electronic assessment of pork carcasses in slaughterhouses, according to a new report from Matís on the results of measurements of the meat ratio of pork. An electronic assessment, which measures the proportion of meat in pork carcasses, gives more accurate results than has been published so far. It facilitates all communication between slaughterhouses and farmers as well as slaughterhouses and meat processing plants where pricing and meat ratio will go hand in hand.

The report also states that the variability of the Icelandic pig population is so small that there is no significant deviation even though the same calculation formula is used, according to measuring instruments, for all pigs.

The reason why it is now possible to introduce electronic food is that the breeding of pig farmers in this country has become purposeful and that the same pig population is used on all farms. The thickness of fat and muscle at certain measuring points has been assessed with electronic measuring devices and these results are compared with information from the Norwegian meat assessment. This was necessary to study the variability of Icelandic pigs within the population as well as between farms. Pig populations in Iceland are comparable to those in Norway.

The project was carried out for the Icelandic Pig Breeding Association.

It is important to land catches on time

It is important that the catch is landed in time so that it can be utilized better, because as soon as the fish is caught, it shrinks and loses freshness. This is the topic of discussion for Guðbjörg Heiða Guðmundsdóttir in her master's project, called Planning for maximum profit in the Icelandic cod industry, in the mechanical and industrial engineering department. Guðbjörg will give an open lecture on her project on 24 September.

After a fish has been caught, it shrinks on board fishing vessels and loses its freshness. This shrinkage reduces the processing capacity and utilization of the fish fillets. It is therefore important that the catch is landed in time so that it can be utilized better. Furthermore, that the processing is taken into account when planning the fishing industry so that the processing can process the fish immediately and bring it fresh to the market. A mathematical model that organizes fishing trips for fishing vessels and production in fish processing is presented. The operating profit of the processing and the fishing industry is maximized with regard to the reduction of the catch. Other factors in the optimization model are inventory status and processing flow.

The aim of the project is to design software that fisheries companies can use to assist in decision-making. The possibility of utilizing the model is demonstrated by applying the model to an Icelandic fisheries company. The effect of the length of fishing trips on shrinkage is investigated in addition to other factors.

Collaboration with Matís

Guðbjörg Heiða's project is carried out in collaboration with Matís and the project has been part of a larger project, Vinnsluspá þorskafla, which is funded by Rannís and AVS.

The project is carried out under the supervision of Pál Jensson, professor at the Faculty of Mechanical and Industrial Engineering at the University of Iceland and Sveinn Margeirsson, PhD student in Mechanical and Industrial Engineering and head of department at Matís ohf. Examiner is Snjólfur Ólafsson, professor at the Faculty of Business and Economics at the University of Iceland.

Place and time: Guðbjörg will give an open lecture on her project on September 24 at 12 noon in room 157 in VR-II in the building of the Faculty of Engineering and Natural Sciences at Hjarðarhagi 4.
