Measurements of the characteristics of foal meat

Domestic horsemeat sales are only about half of production, and while meat consumption is growing with increased economic growth, this does not apply to horsemeat. Horses are generally not bred specifically for meat production, but the meat is a by-product of equestrian breeding and drug production from mare's blood. The popularity of equestrianism and the production of medicines are unlikely to decline in the next few years, so there is every reason to make horsemeat high and thus prevent further marketing problems in the future. Horse meat has been in a marketing campaign abroad in recent months, especially in Asia, but information is lacking about its characteristics. The main goal of the project was to gather and disseminate information that supports and facilitates the way of marketing and sales of horsemeat. Products from three foals slaughtered on 03.12.18 were examined. Thermostat was placed in the refrigerator and in the innermost muscles of the body. Acid syringes were inserted into their spinal muscles after slaughter. All carcasses were deboned in the slaughterhouse at Hella and weighed according to the division into muscle, processing material, bones and fat. Each muscle was divided into 4 parts. The first was in color measurement, the second in chemical measurement, the third in sensory evaluation and the fourth in surgical measurement and measurement of southern shrinkage. In addition, samples were sent for analysis of bacterial counts as well as Listeria bacteria. It took about 17 hours for acidity to fall into the spinal muscles after slaughter and it took about 24 hours in the refrigerator after slaughter for the carcass to reach a perfect ambient temperature at 5 ° C. Measurements on cooked muscle confirm that foal meat is tender meat. Sequence of increasing surgical force (viscosity) is: Puffs <ball steak <arch muscle <hip stitch <thigh tongue <vertebral muscle <lump <outer thigh <brisket <inner thigh muscle. Southern atrophy during cooking was about 25%. Listeria moinocytogenes was never measured and all samples were below microbial criteria. Flavor was generally low or not measurable but increases proportionally more with increasing intramuscular fat as it lasts during storage. According to color measurements, foal meat is similarly light but slightly redder and yellower than lamb and there was a nuance difference between the muscles. After 14 days of storage, the meat became slightly redder / yellower. Muscles used as whole muscle by carcass are only 34.7% of total dead weight. The raw material is 28.9%, which tells us that the proportion of what is normally used by the drop weight is 63.6%. Horse meat has everything to offer in order to be sold as a high-quality meat product, and there should be nothing to prevent it from making better use of this valuable resource.

The main objective was to gather and disseminate information that will support marketing of equine meat. Meat and offals from three foals were analyzed. Temperature was monitored in chiller and carcasses after slaughter and pH loggers were placed in the loin muscle (m. Longissimus dorsi). Yield was measured by cutting the carcasses into muscles, triminngs, fat and bone the day after slaughter. Each muscle was cut into 4 parts.The first was used for measuring CIELAB L, a, b * color. The second was analyzed for nutritional value. The third was cooked and analyzed for sensory properties and the fourth cooked and analyzed for Warner Bratzler shear force and cooking loss. In addition, samples were submitted for analysis of bacterial numbers as well as Listeria bacteria. It took about 17 hours for the pH to drop in the loin muscles after slaughter and it took about 24 hours for the carcasses to reach chiller temperature of 5 ° C. Shear force analysis confirmed the tenderness of foal meat. Cooking loss was about 25%. Listeria monocytogenes was not detected, and all samples were within acceptable limits for microbial counts. Generally, rancid flavor was little or not detected but increased proportionally with increasing intramuscular fat and storage time. Foal meat is similar to or lighter but more reddish and yellow than lamb met and there are slight differences between muscles. After 14 days of storage, the meat became slightly redder / yellower. Whole muscles were only 34.7% of carcass weight. Meat trimmings were 28.9%. The total yield was therefore 63.5%. Foal meat is a high-quality meat product and there are opportunities to market as such, and also to develop new products from the trimmings.

Nordic Center of Excellence Network in Fishmeal and Fish oil

The main objective of this work was to summarize current knowledge on fishmeal and fish oil as well as identify the research needs and create a roadmap for future industry-driven research. The main conclusion was that the quality of raw material, fishmeal and oil are not yet well defined. The real focus by the industry has mainly been limited to nutrients, such as proteins and fats and other components that makeup fishmeal. There has been less focus on the health benefits of dietary contents of fishmeal and oil and the relationship between processing methods and the nutritional and technical properties of fishmeal. In addition, to proactively strengthen the market position and competitiveness, it is crucial for the industry to achieve a common understanding of the needs of their customers in line with a clear profile of the benefits of their products. A communication strategy as well as a research strategy is needed.

Finally, the identity of the industry needs to be clear and transparent to promote a story about the industry to provide a clear and positive image of the industry to be communicated to society. This means, that a communication strategy as well as a research strategy must be established, as there is a lack of communication along the value chain from the industry to the consumers. There is still a lack of understanding by the consumers of why fishmeal is produced, the reasons must be communicated in such a way that it reaches the average consumer.

The industry members are interested in moving forward to sustain the future growth of the industry. Fishmeal and fish oil production has been prosperous for a very long time, but to remain so, cooperation among all stakeholders is crucial for continued progress.

Protein-rich flour from chicken feathers in fish feed

In order to utilize chicken feathers in feather meal, the proteins are broken down to increase the digestibility of the flour, taking into account the needs of farmed animals. In this project, work was done on the development of feather meal with hydrolysis. The chemical content of the feather meal was examined in addition to the amino acid composition and flour from Icelandic chicken feathers was examined in comparison with other experiments where feather meal has been analyzed. Feather meal has an 80% protein content and its digestibility is comparable to that known in fish meal. Feather meal has long been used in animal feed in North and South America and in recent years has been gaining ground as a cheap protein source for farm animals in Europe.

In order to utilize chicken feathers as feather meal nutritious for animal cultivation, proteins are degraded to make the feather meal digestible for farming animals. In this project feather meal from chicken feathers was hydrolyzed to increase digestibility. The chemical content of the feather meal was examined as well as amino acids composition. The Icelandic feather meal was also compared to results of researches conducted elsewhere on feather meal. Feather meal has an 80% protein content and its digestibility is comparable to fish meal.

Attitudes and buying behavior of Icelandic consumers of horsemeat

The aim of this study was to submit proposals to improve the position of horsemeat in the domestic market. A quantitative research method analyzed the attitudes and purchasing behavior of Icelandic consumers (n = 853) of horsemeat. The results were, among other things, that horse and foal meat is not prominent enough and visible in stores all over the country. Most people who buy horse and / or foal meat buy it from the refrigerator or about 50% participants, but the next most common is that people get the meat from friends, relatives, slaughter it themselves, buy it directly from a farm or more. More often than not, people made little distinction between attitudes towards horsemeat on the one hand and foal meat on the other. In terms of willingness to buy products, most said they were less likely to buy minced or smoked horsemeat, but most likely to buy steaks, goldfish and schnitzel. In the opinion of the participants in the study, habits and upbringing have the greatest effect on the consumption of horse and foal meat, followed by knowledge of the product. There are many opportunities in the sale of horsemeat. Most of those who took part in the study were really positive and welcomed the discussion about horsemeat. 96% of the 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 their dog and considered it wrong because of emotions. Superstitions and prejudices against the consumption of horsemeat seem to have passed long ago, but the public's knowledge of the quality and treatment of horsemeat could be increased. Most people considered horsemeat and foal meat to be a clean and environmentally friendly food, free of antibiotics and contaminants. All that can be said is that there are opportunities for marketing horsemeat and it can be assumed that with many trumps in hand, a big hit can be won if the cards are held correctly.

Most people who buy horse and / or foal meat buy it from stores, refrigerated, or about 50% of the participants, but most often people get the meat from friends, relatives, slaughter themselves or buy directly from farms. Attitudes towards horse meat and foal meat were generally similar. In terms of buying a product, most people were the least likely to buy a buried or smoked horse meat, but most likely to buy steaks, guillemots and chips. The respondents believed that habits and upbringing had the most effect on horse and foal meat consumption, but knowledge of the product was in the third place. There are many opportunities in the sale of horse meat provided for quality products. Most of the participants were positive towards horse meat and welcomed the discussion on horse meat. 96% of the participants in the survey had tasted horse and / or foal meat. Those who had not tasted the meat, had no interest, either because they did not eat meat or because they felt like eating their dog and felt it was wrong because of emotions. Pastoralism and prejudice towards horse meat appear to belong to the past, but there is room for improvement of consumer knowledge of quality and treatment of horse meat. Most people considered the horse and foal meat to be clean and environmentally friendly food, free of antibiotics and contaminants. The marketing possibilities for horse meat are good.

Results of continuous monitoring of undesirable substances in seafood from the resource 2018

This report summarizes the results obtained in 2018 for the screening of various undesirable substances in the edible part of Icelandic marine catches.

The main aim of this project is to gather data and evaluate the status of Icelandic seafood products in terms of undesirable substances and to utilize the data to estimate the exposure of consumers to these substances from Icelandic seafood and risks related to public health. The surveillance program began in 2003 and was carried out for ten consecutive years before it was interrupted. The project was revived in March 2017 to fill in gaps of knowledge regarding the level of undesirable substances in economically important marine catches for Icelandic export. Due to financial limitations the surveillance now only covers screening for undesirable substances in the edible portion of marine catches for human consumption and not feed or feed components. The limited financial resources have also required the analysis of PAHs, PBDEs and PFCs to be excluded from the surveillance, providing somewhat more limited information than in 2013. However, it is considered a long-term project where extension and revision is constantly necessary.

In general, the results obtained in 2018 were in agreement with previous results on undesirable substances in the edible part of marine catches obtained in the monitoring years 2003 to 2012 and 2017.

In this report from the surveillance program, the maximum levels for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in foodstuffs (Regulation No 1259/2011) were used to evaluate how Icelandic seafood products measure up to limits currently in effect.

The results show that with regard to the maximum levels set in the regulation, the edible parts of Icelandic seafood products contain negligible amounts of dioxins, dioxin like and non-dioxin-like PCBs. In fact, all samples of seafood analyzed in 2018 were below EC maximum levels.

Furthermore, the concentration of ICES6-PCBs was found to be low in the edible part of the marine catches, compared to the maximum limits set by the EU (Commission Regulation 1259/2011).

The results showed that the concentrations of heavy metals, eg cadmium (Cd), lead (Pb) and mercury (Hg) in the edible part of marine catches were always well below the maximum limits set by the EU.

Drug residues in the Icelandic environment

The aim of the audit was to assess the theoretical release of drugs into the environment (receptors) in Iceland, with an emphasis on coastal waters, rivers and lakes. For medicinal products used for humans, an assessment was made of the concentration of these medicinal products in the sewerage system in the capital area and in two selected locations outside the capital area. For medicinal products used in agriculture and aquaculture, a theoretical assessment was made of the release of medicinal products from production units where the emissions could be the highest. The potential concentration of the drugs in the receptors was assessed and these values were compared with the expected risk, as there are environmental limits. The drugs that were examined and evaluated were determined on the basis of Icelandic sales figures and the priority list of the European Union's Water Framework Directive, together with the results of previous research. The following human medicinal products were examined: estradiol, ethinyl estradiol, amoxicillin, azithromycin, fluconazole, paracetamol, ibuprofen, diclofenac, metoprolol, fluoxetine, sertraline and the veterinary medicinal products emamectin benzoate (laxalucalicylphenyl). Theoretical evaluation suggests that the levels of ibuprofen, amoxicillin, fluoxetine, paracetamol, diclofenac, azithromycin and sertraline need to be further investigated in sewage treatment plant receptors. The results for the veterinary medicinal product do not indicate a risk of procaine benzylpenicillin used in pig farming or emamectin benzoate used in aquaculture.

Nutritional value of goat products - Meat and milk

This report on the nutrient content of goat meat and goat milk is a part of the project “Added value and special status of goat products”. The project is supported by the Agricultural Productivity Fund and carried out at Matis in cooperation with the Association of Goat Farmers in Iceland. Goat carcasses were cut into legs, loin, forequarters and flanks. Proportions of meat, bones and waste were determined. On the average meat was 66% of the carcasses, bones 31% and waste 3%. The meat was analyzed for proximates. The protein content was high (21% protein for meat from the whole carcass). Fat content was generally low (4-24%). Goat milk was sampled from spring until autumn 2018. Each milk sample was collected from composite milk from 3-57 animals. Fat content was on average 3.9%, protein 3.7% and lactose 3.9%. The contents of polyunsaturated fatty acids and omega-3 fatty acids were higher than in Icelandic cow milk. The results should be valuable for promotion of goat products, work on nutrient declarations and product development.

Hunting, processing and exporting of live bait king

This report outlines the implementation and main results of a research project that took place in the years 2012-2013. The reason for delaying the publication of the final report of the project is that in 2013 the owner of the project, Sægarpur ehf. bankrupt. The project was therefore not completed and has been largely dormant since 2013. However, since most of the project had been completed before Sægarpur went bankrupt, the authors consider it right and obligatory to publicly report here what took place in the project and what the main results are. its were. The aim of the project was to develop fishing, processing, storage and transport of live bait kingfishers, as well as to explore the market for such products. Experiments were carried out with different catch treatments on board a fishing vessel and storage or transport, which gave indications that with the right handling and finishing it would be possible to keep the bait king alive for approx. week. the aim had been to ensure at least 10 days of survival in order for it to be considered realistic to intend to export a live bait king. However, the results of the experiments showed that when more than a week had passed since the hunt, survival decreased rapidly and the meat had become unfit for consumption on the tenth day. It is possible that these processes could be better developed to ensure better survival, but based on these results, the shelf life is not long enough to be considered a viable option at this time. Attempts were also made to keep the bait king alive in a cycle system in a fish tank. The aim of these experiments was to investigate whether it was possible to store live bait king in a "warehouse" for processing on land. A circuit system was equipped with filter equipment that was sufficient to keep the bait king alive for a week. The authors believe that it would be possible to extend the time with more powerful filtering equipment. These results must be considered positive and conducive to the fact that they could be taken up by companies that process bait king. Markets for live bait king were also examined, but it can be said that this survey has finally brought home the truth that the export of live bait king is not a viable option. It is simply a better option to win the bait king here at home. If market conditions change, however, it is not ruled out that processes can be improved to make such exports possible.

This report contains an overview of the progress and main results in a research project that ran in 2012-2013. The reason for the delay in publication of this final report is that the project owner was declared bankrupt in 2013 and the project has been dormant since then. The authors of the report did however feel obligated to make public the progress and main results that were achieved before the owner went out of business. The aim of the project was to develop best practice for catching, handling, packaging, storage and transport of live whelk; as well as studying the markets for live whelk. Experiments were made with different onboard handling, storage and transport of live whelk. These experiments indicated that it should be possible to keep the whelk alive for one week after capture, with correct handling. The goal had however been to ensure that the whelk could be kept alive for at least ten days. Experiments were also made where it was attempted to keep whelk alive in a regular plastic fish-tub equipped with a circulation system. The objective with this was to examine if whelk could be stored, in a relatively simple and inexpensive manner, in-stock for land-based processing. The results indicate that such a system could be used to keep a living inventory of whelk for the processing. The authors of this report are confident that the timeframe could be extended by fitting the system with more efficient filtration equipment. The markets for live whelk were briefly analyzed and the results of that analyzes indicate that export of live whelk from Iceland is not economically feasible or practical. There is simply too little premium paid for live whelk at the moment.

Increased quality and stability of frozen herring products

Freezing and cold storage is an effective method of maintaining quality and extending the shelf life of seafood. The production of frozen products equals the supply of products where fishing is seasonal. There are many factors that can affect the quality and stability of frozen products. These include the condition of the raw material, processing methods and conditions for storage and transport, to name but a few. The aim of the study was to investigate the changes that take place in the chemical and physical properties of frozen herring fillets with regard to the condition of raw materials during processing and conditions in cold storage. Atlantic herring was processed before and after death solidification, and the fillets were stored under stable storage conditions (-25 ° C) and unstable conditions (at -25 ° C for 2 months, then -12 ° C for one month and then again at - 25 ° C for the duration of storage). To study the stability and physical properties of the products, water loss (drip), boiling efficiency and color were measured, in addition to which both light and dark fish muscles were measured for water resistance, pH, chemical composition, fatty acid composition, enzyme activity and evolution. The study showed that it is important for the fishing industry to ensure uniform and correct temperature control when products are stored in the freezer. Processing and freezing before death solidification, in parallel with stable storage conditions, has a positive effect on the quality and stability of herring falcons. In addition, the study confirmed that the fatty state of the herring muscle, often referred to as the dark muscle, is very sensitive to development. In order to extend the shelf life of frozen herring fillets, it is recommended that this muscle be removed in parallel with deep skinning.

Freezing and frozen storage has proven to be an effective method to preserve and prolong the storage life of seafood products. Production of frozen products provides all year around product availability although the catching is seasonal. There are several factors that can affect the quality and stability of frozen fish products, including the state of the raw material, processing methods and storage conditions. The aim of the study was to explore how physicochemical properties of frozen herring fillets are affected with respect to the state of the raw material during processing as well as storage conditions. Atlantic herring was processed and frozen pre- and post-rigor and stored at stable (-25 ° C) and abused storage conditions. To investigate the storage stability and physical properties of the fillets, thawing drip, cooking yield and color were evaluated, as well as proximate composition, fatty acid composition, pH and lipid degradation of the light and the dark muscle. The study demonstrated the importance of stable and controlled temperature during storage and transportation of frozen herring products. Processing and freezing pre-rigor, in combination with stable storage conditions, was shown to be beneficial in terms of preventing lipid oxidation, as well as reducing thawing loss and maintaining the cooking yield of the herring fillets.
