Horse and foal meat has many good qualities, but is a little known consumer product in the world. The nutritional value of the meat is good, it is lean and at a relatively low price compared to other meats. Research on horse and foal meat has been deficient over the years, but Eva Margrét Jónudóttir and other experts at Matís have worked diligently to improve it in recent years.

This summer, Eva Margrét's last project, a specialist at Matís, completed horsemeat, but she has in recent years conducted various research in that field. In connection with her BS degree in agricultural sciences at the Agricultural University of Hvanneyri, her interest in this work was sparked and her final project dealt with the attitudes and buying behavior of Icelandic consumers of horsemeat. Subsequently, she pursued a master's degree in food science at the University of Iceland in parallel with her work at Matís, where her main research topics were the quality and properties of horsemeat. We talked to Eva Margrét about the projects she has done in this field, their origin and her ongoing work in the field of food research.

What was the original purpose of your research?

"I had long wondered that the people I met were rather indifferent to horsemeat, but I myself was raised with home-slaughtered horsemeat and thought it was tasty and wonderful. I wanted to study horsemeat and draw attention to it, but had difficulty finding guidelines for such research. I was then pointed out to Guðjón Þorkelsson, who applied for and received funding for the projects in the Productivity Fund and Kolbrúna Sveinsdóttir, experts at Matís, and they were there for the fight, "says Eva Margét.

Eva Margrét researching horsemeat samples

"In the previous study I did, the goal was to submit proposals to improve the position of horsemeat in the domestic market. This was done by analyzing the attitudes and buying behavior of Icelandic consumers of horsemeat, discussing with stakeholders the status of horsemeat in the country and examining the actual state of knowledge in this field at that time. The purpose of subsequent research was to obtain and disseminate information that supports and paves the way for marketing and sales of horsemeat, "explains Eva Margrét.

The purpose was also to show that horsemeat is of high quality, has a full mission in the market as a luxury product and that its shelf life can be extended considerably with shorter processing processes, better packaging and more cooling. It all worked out.

Surprising results

Initially, it was planned to get 400 answers to a questionnaire that was posted online in the previous study. A total of 850 responses were received, which immediately gave the idea that consumers were interested in the material.

The main results were that most of the participants in the study were really positive and welcomed the discussion about horsemeat, but the public's knowledge of its quality and treatment could be increased. They showed that 96% participants had tasted horse and / or foal meat, but those who had not tasted were not interested, either because they did not eat meat over their heads or because they felt like eating the dog. time and considered it wrong for emotional reasons. Most people considered horsemeat and foal meat to be a clean and environmentally friendly food, free of antibiotics and contaminants. It also became clear that people from all over the country did not think horse and foal meat was prominent enough and visible in shops.

The results of the latter studies showed in black and white that horsemeat is a quality product that can be maintained in good condition for a long time if it is handled correctly. Chemical measurements were performed confirming that foal meat is nutritious and the total number of micro-organisms after 15 days of storage at 2-4 ° C was below the limit values which confirmed good production methods and safety for consumption. The foal meat was tender and the taste and desire smell was generally not or not very measurable.

Experiments with the shelf life of horsemeat in retail packages. Here you can see the condition of the meat after a different storage time in a foam plastic tray with plastic film over it.

The results of experiments on shelf life exceeded expectations for wholesale packaged vertebral muscles as no changes were measured after 28 days at -1.5 ° C compared to the stated 2-3 weeks shelf life at 4 ° C. This was possible by lowering the temperature by 3-4 ° C, blocking light and limiting access to oxygen. Experiments with retail packages such as foam plastic trays with plastic film over as is common in meat tables did not work as well, but the number of days in wholesale did not affect the shelf life of retail in this case as there were no damage during the wholesale storage period and the meat quality was very constant.

The results of the study as a whole showed that horsemeat should have good potential on the market and it is hoped that it will be useful in preparing guidelines in this regard. They could lead to improved work processes that increase the shelf life of products and thus prevent unnecessary waste of horsemeat.

Eva Margrét hopes that over time, people will start to see horsemeat as a limited resource and not as a surplus of something else.

What have been the effects of this research and what are the future prospects for horsemeat in the Icelandic market?

"There was a lot of interest in this topic first when we were starting the research and we got coverage in the various media. I went to a variety of interviews and people along the way were endlessly asking about this research, what was in the news and how it was going. But after we finished the projects, the discussion has calmed down, "says Eva Margrét. 

"I have no follow-up projects on my cards yet, but I still hope that in the future I will be involved in more horsemeat research or some kind of product development project in connection with horsemeat. There is still so much to take in and many untapped opportunities there.

As for the future, we have one more idea for a project that did not receive funding in the last experiment, and it was called "Horse meat - cooking and value added". In short, it was about promoting horsemeat as a quality food product for restaurants, canteens and general consumers in collaboration with stakeholders through open horsemeat events, experiments on the various versions of cooking and the preparation of promotional material for publication. Here one would have to keep going and not give up. There is a lack of a website about horse products where you can find research on horsemeat, nutritional value, cooking instructions, recipes, meat cuts, bits of information or fragments from the history of horsemeat, storage instructions, etc. all in one place. This could even be an improved version of The Icelandic meat book which is a fairly good foundation to build on, "says Eva Margrét.

Eva Margrét Jónudóttir

"It is also my distant dream to one day, together in a book or web magazine, take everything between heaven and earth that concerns the consumption of horsemeat and the utilization of the Icelandic horse. Both on a theoretical basis from the point of view of a food scientist but also in a historical or more creative way. "

Projects such as the horsemeat projects in question are carried out in various areas at Matís but fall under the service category meat. If you are interested in getting to know more about research and innovation when it comes to meat processing and production, you can watch a presentation of the material here: Emphasis: Meat production and meat processing - research and innovation.

In the next few days there will also be a new episode of Matvælinu, Matís' broadcast on research and innovation in food production. Eva Margrét will talk about her horsemeat research as well as other projects she has worked on and put these issues in context with fun experiences and bits of information.

About Nordic Food in Tourism

Nordic Food in Tourism is one of the three Presidency projects of the Nordic Council of Ministers under the auspices of Sustainable Tourism in the North. The Ministry of Industry is leading the project in collaboration with the Icelandic Travel Cluster and Matís. Nordic partners come from Norway, Denmark, Sweden, Greenland, the Faroe Islands, Åland and Finland, as well as an expert group from universities and the business community.

One of the main goals of the project is to realize the changing consumption behavior of travelers and how they choose to access food and products during their travels. Climate change and the changing environmental awareness of visitors to the Nordic countries have a lot to do with changing behavior, and efforts must be made to find out which factors will change or be most affected. Among the products of the project are answers to what foods, production methods and or changed composition of products our future visitors will seek and how we need to develop and improve methods to meet it. Great emphasis is placed on focusing on food in tourism and not only food tourism. Partners in the project will also use the source of knowledge and results that emerge to disseminate and become leaders in sustainability and development when it comes to assessment in tourism.

A workshop on salmon farming will be held on October 27 at Ölvus Cluster, Hafnarberg 1, 815 Þorlákshöfn.

The meeting starts at 08:30 and ends at 17:00 the same day.

The workshop subjects:

  1. Salmon feed: new sources and optimal composition for different environments
  2. New development in sea- and salmon louse
  3. Production of large smolts in hatcheries
  1. Salmon feed will be a very dynamic area of research and development in the future. With feed requirements of salmon growing in extreme environmental conditions, such as low temperature, are not fully understood. Furthermore, technical solution to minimize movements of fish in sea cage during the coldest periods in winter could improve conditions of fish during the coldest months
  2. Several options already exist for chemically treating salmon lice in sea cages. However, there are two main problems associated with treating lice in such a way. Firstly, there are negative environmental impacts and secondly, lice can and have developed resistance to many of the available chemicals currently being used
  3. There has been a growing interest in land-based salmon farming under more controlled environment. Large smolt farming is a land-based farming, with longer growing time ashore and shorter in ONP, reducing risk in farming with higher cost. Reducing lead time in sea also enables producers to reduce the spread in biomass throughout the year. This may be one of the most sustainable ways of maximizing utilization of licenses.

The meeting is open to anybody interested in salmon farming. Included are refreshments at the meeting and reception at Lax-inn in Reykjavík after the meeting. The cost is ISL 3,000.

The meeting will be in English, and registrations will be open on the home page soon.

The aim of this project was to gather and disseminate information that supports and paves the way for marketing and sales of horsemeat. This was done, on the one hand, by collecting information on the utilization, nutritional value, color and effect of storage in the refrigerator on taste quality, cutting power and southern shrinkage of foal meat, and on the other hand by studying the shelf life of fresh horsemeat to see if it could be extended.
Foal meat was stored in an air-packed container at 2-4 ° C for 14 days where the main nutrients, minerals, vitamins, acid drop and temperature after slaughter, color, surgery, microorganisms, southern shrinkage and deboning were measured. In addition, fatigue, stench and taste were assessed by sensory evaluation on a scale.

The aim of the project was to make an assessment of the quality of Icelandic and imported vegetables in the consumer goods market from autumn and winter. Measurements of antioxidants and antioxidant activity from a previous project funded by the Horticultural Development Fund were also continued. The excellent quality of Icelandic vegetables was revealed in the autumn, but as the winter progressed, shortcomings for some types of vegetables became apparent, which there is reason to work with and promote increased quality in order to strengthen the position of domestic production. Carrots and carrots can be particularly pointed out, but their quality could be improved in winter. Antioxidants were found in all types of vegetables. The significant antioxidant activity of potatoes came as a surprise and their health may be underestimated.

An International Conference on The External Dimension of the Common Fisheries Policy

A conference focusing on the external dimension of the common fisheries policy was held within the framework of the FarFish project in early June 2021. The aim of the conference was to review the implementation of the External Dimension of the CFP and to provide recommendations ahead of the next revision of the CFP.

The conference was attended by high-level experts and key stakeholders from the fishing industry and NGO sectors, together with relevant policy makers, scientists and academics, which contributed to discussions on the importance, advantages and challenges of the EU role in international fisheries management and ocean governance.

The conference spanned over two days, with the first day consisting of presentations and panel discussions from high-level experts; and the second day was more in the form of a workshop where different experts and stakeholders “dug deep” into how to improve management under fisheries agreements.

Recordings from the conference are now available on the FarFish website, along with a summary leaflet and main conclusions from day 1 and day 2.

Monitoring, control and surveillance (MCS) are challenging in wild capture fisheries and insufficient MCS has resulted in unsustainable fishing practices, data limitations in stock assessment and management, lack of transparency and unfair competitive advantage for those not following the rules. Major expenses and efforts are awarded to MCS, but effectiveness and coverage is generally very limited. There are however a number of emerging and already available technological solutions that can be applied to significantly improve MCS and reduce costs at the same time. These solutions are generally referred to as Electronic Monitoring (EM) or Remote Electronic Monitoring (REM) solutions.

The Nordic countries are generally considered to have well-regulated fisheries and relatively good MCS. The authorities in these countries do however also understand that they need to keep up with new technology and use them when applicable to improve their fisheries. Denmark, Norway and Iceland have for example been awarding increasing attention to REM in recent years. As part of that work, the Nordic Council's Working Group for Fisheries (AG-Fisk) funded a networking project in 2019 that was to facilitate a conference on REM, where experts in the field would present information on current state and emerging solutions for Fully Documented Fisheries (FDF). The conference was held in November 2019 in Reykjavík and the proceedings along with short summary are presented in this report. The report also contains concluding remarks at the end where the most important issues are summarized, and comments made on developments that have taken place from the time of the conference until the publication of this report.

It is obvious that EM will not solve all problems when it comes to MCS of fisheries, but such solutions can be important tools to facilitate more efficient MCS and even reduce cost and / or increase coverage. The Nordic countries have not been at the forefront of implementing REM technologies (possibly with the exception of Denmark) where countries such as Canada, US, New Zealand, Australia and Chile have paved the way. The Nordic countries are therefore in the position to learn from those that have gone before them, use what has proven to be successful and avoid making the mistakes they did.

Several relevant pilot trials and research projects are currently ongoing in the Nordic countries and at European level. There are also ongoing similar initiatives elsewhere in the world and full implementation of some elements of REM are also taking place. It is important for the Nordic regions to follow and take part in these initiatives, as the authors of this report believe that REM solutions can be extremely effective tools for MCS in the future.

Unconfirmed paternity of lambs has led to various advances in sheep breeding in Iceland. Most notable is research related to hereditary diseases, where the confirmed paternity and maternity of individuals is a prerequisite for tracing the lineage of the disease. Modern parental analysis of livestock is based on the analysis of variable genetic markers and statistical comparisons between parents and offspring. The aim of this project was to develop a tool for parental analysis in Icelandic sheep using molecular genetic methods. It is important for sheep breeding to have the opportunity to confirm the lineage of animals. This can be very useful, especially when genetic defects are found in the offspring of insemination rams. It is also essential that the item is properly pedigree. In this study, 17 internationally recognized (ISAG) genetic markers were tested for parental identification in the Icelandic sheep population. The database is based on samples from 514 sheep. The results of the project show that the ISAG genetic boundary works well within the Icelandic financial stock and its sub-stocks. This project has therefore added a new tool to the toolbox of sheep breeders and recruiters.

Development of new charr feed // Novel enhancement of soy meal for Arctic charr diets

AVS funding

Aquaculture is growing rapidly around the world and is playing an increasingly important role in ensuring food security. Iceland is the largest producer of char in the world, but char has a great need for protein, which has mostly been met by feed that is rich in fishmeal. Fishmeal, on the other hand, is an expensive source of protein, so feed costs in charr farming are around 50% of production costs, in addition to which fishmeal is a limited resource. It is therefore important to look for new protein sources for char producers. One such option is to use soybean meal, which has been used successfully in salmon farming. However, there are studies that suggest that soybean meal may have a negative effect on the growth, intestinal flora and general well-being of salmonids.

This report discusses the main results of the AVS project "Development of new charr feed", the aim of which was to reduce feed costs and increase sustainability in charr farming by replacing fishmeal with soybean meal in feed. The project also sought to gain an understanding of the effects of different "treatment" soybean meal on the growth, intestinal flora and welfare of char.

Four different types of feed were studied, ie. conventional feed with fishmeal (FM), with untreated soybean meal (US), with enzyme-treated soybean meal (ES), and with untreated soybean meal with added beneficial bacteria (USP). The survival, growth, behavior and intestinal flora of the char fed for 10 weeks on the aforementioned four types of feed were then compared. The char that was tested was a small fish at the stage where there is a lot of growth and the intestinal flora is being shaped; and therefore the effect of the feed is particularly important.

The main results of the project were that feed containing Hypro soybean meal with added FOS beneficial bacteria significantly reduced growth, compared to the other types of feed. The enzyme-treated soybean meal, which contained degraded NSPs that act as beneficial bacteria, as well as the untreated soybean meal with added beneficial bacteria, contributed to a more diverse intestinal flora and increased levels of lactic acid bacteria (LABs) that have been linked to disease and immune resistance, . The results also showed that the fish's behavior towards the untreated soybean meal was significantly different from that of the other feeds, in that they showed less interest in the feed.

The results indicate that the addition of beneficial bacteria at this stage of growth promotes positive changes in the intestinal flora, and can therefore lead to increased tolerance to stress and disease later in life. However, this seems to be detrimental to fish growth. Further research is therefore needed to determine whether the growth will pay off in the later stages of charr growth and whether survival and other positive traits will increase. FOS benign bacteria may not be suitable for fish at such an early stage of development, but it seems that FOS affects metabolism and intestinal needs and the immune system. But further research is needed to draw further conclusions. The enzyme-treated soybean meal did not have the same negative effect on growth, but the variability was greater. LABs in the intestinal flora indicate that the treatment promotes endangered health and resistance to infections, without affecting growth. The results suggest that enzyme treatment of soybean meal in feed contributes to improved health and survival of char. It is important that future research examines the results of this project and compares it with the condition of intestinal tissues. It is also important to further investigate how metabolism, behavior and intestinal flora interact with different feeding in previous life stages, as well as what the effects are on long-term growth and well-being.

Aquaculture is globally growing in importance as part of the solution for future food security. In Iceland one of the most important farmed species is the salmonid, Arctic Charr, and Iceland is the world's leading producers of this cold-water, carnivorous species. Arctic Charr has a high dietary protein requirement which is traditionally provided by diets high in fish meal protein. This drives feed costs that are 50% of the total production costs and puts pressure on wild capture fisheries from which fish meal species are sourced. To facilitate the further expansion of Arctic charr aquaculture it is necessary to find less expensive and more environmentally sustainable feed ingredients. One potential alternative that is widely used in Atlantic Salmon aquaculture is soybean meal, however increasing evidence suggests that for some salmonids, untreated soybean meal can have negative consequences for growth, good health and welfare.

The overall aim of this study was to decrease Arctic Charr feed costs and improve the long-term sustainability of salmonid aquaculture in Iceland by replacing fish meal with untreated and treated soybean meal. This study also aimed to understand the wider consequences of untreated and treated soybean meal on the growth, gut health and welfare of Arctic Charr.

Four different diets were assessed, a fish meal control (FM), an untreated soybean meal (US), an enzyme pre-treated soybean meal (ES) and an untreated soybean meal with an added prebiotic (USP). The survival, growth performance, gut microbiome assembly, and behavior were of juvenile Arctic Charr fed each of these diets during a 10-week feeding trial were compared. The juvenile life stage was selected since it is a period of crucial developmental, when growth rates a very rapid, and the gut microbiome is colonizing, so impact of differing diets can be obtained quickly.

The key findings of this report were that the addition of FOS prebiotic to untreated Hypro soybean meal feed treatment significantly reduced growth compared to the fish meal control when all other feed treatments including the enzyme treated soybean meal performed significantly the same as the fish meal control. The enzyme treatment of soybean meal which aimed to have a secondary benefit of the broken down NSPs acting as prebiotics, as well as the untreated soybean meal with prebiotic had higher gut microbiome diversity as well as a greater presence of Lactic Acid Bacteria (LABs) which are both associated with positive benefits such as more immune robustness and resilience to disease and infection as well as benefits for nutritional uptake and growth. There was also a notable difference in behavior where the fish fed the untreated soybean meal with added prebiotic were both shyer and less active than the fish fed any other feed treatment, indicating that they were more reactive individuals.

When the results of these different tests are viewed together this suggests that the addition of pure prebiotics at such an early developmental stage does promote beneficial changes to the gut microbiome which suggests that the fish will be more resilient to stress and disease later in life and may receive other benefits of prebiotic addition too, however at this early stage the combination with low growth performance suggests that the immune system and gut development may be stimulated but at the cost of energy being drawn away from growth. Salmonids given FOS should be followed from early development through to harvest to see if growth can be compensated and if survival or performance is in fact improved. Otherwise these results may indicate that FOS may not be suitable to apply to diets during such early stages of development, when growth curves are steep naturally. The observation that these fish were also had more reactive coping strategies suggests that the prebiotic application may also effect metabolic rate which could be linked to the stimulation of the gut and immune system, but further experimentation will be needed to elucidate this and also to investigate the consequence of this altered behavior, which could potentially reduce the welfare of an intensively farmed fish. On the other hand, the enzymatic treatment of soybean meal did not show the same negative impact to early growth performance but did influence a higher diversity and LABs presence in the gut microbiome suggesting this method of threatening soybean meal may bring benefits to health and resilience without as much trade-off. These enzyme-soy treated fish groups were also slightly more reactive than the control treatments, but the impact was not as pre-announced as for the prebiotic added treatment. Overall the results suggest that the best potential benefit to long term health and survival of charr when soybean meal is pre-treated with enzymes when used in the diet.

It will be extremely important in the future to combine these results with gut histology data to clarify the impact of differing treatments to internal gut morphology and health. It will also be important to further study how metabolism, behavior and the gut microbiome interact with dietary treatments at this early development stage and what the long-term consequences for production and welfare will be.
