Air-dried lamb. Final report / Air dried lamb meat. Final report

The aim of the project was to develop products from air-dried lamb in collaboration with farmers. The project was also about increasing farmers' skills in processing and processing lamb into air-dried products, ie. make them suitable for the manufacture of such products. A co-operation group of 5 farmers was formed who were interested and have facilities for home processing of such products. The aim was to develop one product with each farmer, and the product must meet all the requirements for safety, quality, finish and presentation that are relevant for products in the consumer market. In the main, it went well. Farmers were able to adopt the production methods necessary for dry processing and they developed new production processes and products, each different from what is on the market today. The results therefore strengthen the farm in question for the development of new products from its own raw materials and thus their working basis.

The aim of the project was to develop products from air dried lamb in cooperation with farmers. The project centered as well on extending farmers' knowledge on processing and curing methods for these products. Group of five farmers was selected to participate in the project. All farmers had an interest and facilities for this kind of processing. The products should fulfill all requirements regarding safety, quality and presentation of consumer products. This succeeded in most cases. The farmers adopted practices needed in producing dry aired products, new processing methods and products were developed. The results will thus strengthen each producer in development of new products from their own raw material, thus boosting their own operation.

Gold in the fists of Ægis / Antioxidants from Icelandic marine sources

The purpose of this project was to screen for anti-corrosive substances from Icelandic seafood such as algae, capelin and sagebrush, to be used as a food additive, target food or as a dietary supplement. Particular attention was paid to the possible use of polyphenols from algae as natural antioxidants to prevent the development of fish products and fish muscle proteins (isolates). This was done by screening for antioxidant activity with several types of antioxidant tests. The most promising antioxidant was chosen to better study its antioxidant properties in food models, i.e. washed cod muscle system, cod protein system and in fish burgers. The results showed, among other things, that polyphenols from the seaweed (Fucus vesiculosus) have high antioxidant properties and are promising for use as a dietary supplement or in food to promote greater stability, taste and nutritional value.

The aim of this project was to explore the natural antioxidant activity of marine sources like seaweed, capelin and cod spleen to use as food additives, functional ingredients or nutritional supplements. The potential application of algal polyphenols as novel natural antioxidants to prevent lipid oxidation of fish muscle and fish protein based products was of special interest. This was done by screening for antioxidant activity using different types of antioxidant assays. The most promising antioxidants were selected and their antioxidant properties studied further in fish model systems and fish patties. The results showed that phlorotannins isolated from bladderwrack (Fucus vesiculosus) had very high antioxidant properties and has a potential as nutritional supplements or food additive to enhance oxidative stability, flavor quality and nutritional value.

Will one of the best biotechnology laboratories in the world be located in Sauðárkrókur?

Recently, a special laboratory was opened for cell research at the Matís Biotechnology Center in Verin in Sauðárkrókur, and Dr. Hólmfríður Sveinsdóttir at Matís oversees the laboratory.

Líftæknismiðjan always employs four specialists from Matís, three from the Division of Biotechnology and Biotechnology and one from the Division of Processing and Value Added. Líftæknismiðjan conducts highly specialized research on the bioactivity of marine biomaterials, and Matís' goal is to make the laboratory one of the best in the world in this field.

Bioactivity can include anti-cancer, antihypertensive and antioxidant activity. The perfect equipment for measuring bioactivity measured already exists in vitro situations (in test tubes) performed under the direction of Dr. Patriciu Hamaguchi. Since in vitro research has shown good results, there is great interest in examining bioactivity in more detail in cell models where in vitro bioactivity measurements have been criticized for their ability to predict activity in biological systems. A measurement method is already being developed to evaluate the antioxidant activity of fish peptides in Hep G2 cells.

This is an important step forward in the bioactivity of fish and marine products and is necessary for the next stage of this research, which involves clinical trials in animals and humans.

Matís at the FÍF spring conference

There was a lively discussion at the spring conference of the Association of Icelandic Fishmeal Producers, which was held on 8-9. last April at the Grand Hotel. Matís did not give up and had two lectures on his side there.

In his lecture, Lárus Þorvaldsson discussed the cooling of pelagic catch for processing on land. There he went over the results that have been achieved with continuous temperature measurements and follow-up on board the pelagic vessels of Síldarvinnslan, but in addition he presented the possibilities of computerized thermodynamics and hydrodynamics for design, processing control and decision-making in pelagic fishing.

Sigurjón Arason also discussed Matís' research on seasonal fluctuations in the fat and dry matter content of pelagic fish, as well as his input on market conditions and the potential for utilization of various pelagic species. Sigurjón also discussed Matís' work in creating a quality indicator for pelagic fish, but in recent months Matís has developed sensory assessment methods to assess the freshness of pelagic species.

Both lectures aroused great interest among conference guests and it is clear that Matís' research is being closely monitored for the benefit of the Icelandic fisheries sector.

Risks and benefits of food consumption and dissemination of information to consumers

From 14.-15. In April, an international workshop (Workshop) on "Methods for analyzing the risks and benefits of food consumption and dissemination of information to consumers" will be held at Matís' new headquarters.

This workshop is part of the SAFEFOODERA EraNet project on risk and benefit assessment. A total of 23 experts from 8 countries are expected to take part in the meeting.

The aim of the project is to develop methods to analyze the risks and benefits of food consumption and the dissemination of information to consumers. In order to achieve this goal, the intention is to utilize knowledge and experience in risk and benefit analysis that has been built up in other fields of study, such as medicine and pharmacology, microbiology, environmental sciences, sociology and economics, and to transfer as well as adapt the methods to food and nutrition. The intention is to collect data and make use of experience that has been built up in the fields of study that use risk and benefit analysis today, and to transfer this knowledge and develop methods that are suitable in the field of food. 

Matís' role is to collect data and utilize the experience that has been built up in the field of microbiology on risk assessment and transfer this knowledge to develop methods for risk and benefit analysis in food. The work in the project is based on all aspects of risk and benefit analysis, ie risk and benefit assessment, risk and benefit management, risk and benefit presentation.

The conference will feature, among others, Hans Verhagen, who is a highly regarded professional in the field of risk-benefit analysis in food. Hans heads a 45-50-person department working in this field at the RIVM National Institute for Public Health and the Environment in the Netherlands. In addition, he holds a professorship at Maastricht University in the Netherlands. The meeting these days is therefore a good opportunity to learn about these issues from those who are among the leaders in their field.  

The agenda of the meeting can be seen here.
