To strengthen the position of saltfish, with its long tradition, history and connection to Nordic livelihoods, it is important to strengthen the entire value chain, from producers and retailers, to chefs and consumers. The aim of the project "Saltfish delicacies" is to develop new or improved ready-made dishes based on traditional saltfish, and 16 participants from Iceland, Norway and the Faroe Islands are involved. The group consists of experts in saltfish processing and quality, cooking, food production, media and the travel industry.

Following the project's workshop held in the fall of 2022, work continued with ideas for salted fish dishes and salted fish products in collaboration with Grím Kokk, Matís, Menntaskolin in Kópavogur, Icelandic salted fish producers, Klúbbs Matreiðslumestar and Íslandstofa, with the aim of promoting salted fish better with a focus on grocery stores.

Salted fish products and recipes for salted fish dishes were developed within the project and in collaboration with the Crown, the products were put on sale and recipes for salted fish dishes were published on the Crown's recipe page in March 2024. The results were then presented at the project's workshop in the Faroe Islands in May 2024. Both salted fish products and recipes were very positively received, and there are hopes that it will be possible to offer salted fish delicacies in Icelandic supermarkets permanently. It's an uphill battle, however, as the battle for grocery store shelf space is fierce, and it can be difficult for smaller producers to invest in finished salted fish in the quantities that have been available to them so far. It is necessary to increase flexibility and strengthen cooperation within the salted fish chain to pave the way for salted fish domestically, to revolutionize its image and reputation.

To strengthen the position of saltfish, with its long tradition, history and connection to Nordic livelihoods, it is important to strengthen the entire value chain, from producers and retailers, to chefs and consumers. The aim of the project "Saltfish delicacies" is to develop new or improved ready-made dishes based on traditional saltfish, and 16 participants from Iceland, Norway and the Faroe Islands are involved. The group consists of experts in saltfish processing and quality, cooking, food production, media and the travel industry.   

This report describes the workshop "What is saltfish?" which was held in the house of the Menntaskólin in Kópavogur, September 28, 2022 in collaboration with Matís, the Menntaskólin in Kópavogur (MK), Grím Kokk, Klúbbs Matreiðslumeista and Icelandic saltfish producers. The goal of the workshop was to share knowledge from various sources, and look for ways to strengthen the position of salted fish in the domestic market, and about 40 people attended the workshop. Short presentations were given by Matís experts on the history, culture, effectiveness and dewatering of salted fish. Also about the knowledge and attitude of consumers towards salted fish and its consumption in Iceland. The sensory properties of salted fish were presented, and attendees had the opportunity to taste and compare two types of salted fish and two types of salted fish. MK culinary students then presented their ideas behind salted fish dishes, which were served on the table. After that, we worked in three groups, each of which discussed the following topics: "What is salted fish - can we call salted fish salted fish?", "How do we reach the young people?" and "How can the product range be increased?".

The results of the workshop showed that it is important to distinguish between what is truly salted fish on the one hand and salted fish on the other. Salted fish, usually lightly salted or overnight salted, does not have the same characteristics as salted fish, which is fish finished with salt and brine and then dry-salted even for weeks, which after dehydration gives this product unique properties such as a characteristic taste and firm texture. It seems that there are endless opportunities and opportunities for the saltfish. However, we need to pay better for the way of salted fish to the Icelandic market. Saltfish should really be to us Icelanders, on par with what Parma ham is to Italians, at least. To promote knowledge, respect and consumption of salted fish, it needs to be better known and made more visible, not least among younger age groups. What hinders chefs and producers of products is that it is often difficult to obtain fully prepared, properly watered salted fish domestically. Dewatering requires a problem, but often the facilities, time or knowledge are not available. We need to reach younger consumers and improve the reputation of salted fish in general. The name saltfish is not very appropriate, as it has a reference to salted fish and has a negative image due to its association with second class fish. Dehydrated salted fish should not be too salty. Perhaps finished, dehydrated saltfish should be called something other than saltfish.

Consumer survey on salted fish

There is a long tradition for processing salted fish in this country, but before that the salt was used primarily to extend the shelf life of the fish. Today, salted fish is considered a gourmet product that is very popular in many parts of the world, not least in Southern Europe, where the traditions and quality of Icelandic salted fish play a major role. Matís ran workshops with salted fish producers and chefs in April and May 2019. Their goal was, among other things, to assess the position of salted fish in the domestic market. It was stated that information was needed on Icelanders' views on salted fish in order to better assess the opportunities in Iceland. Based on the results of the workshops, an online survey was conducted with the aim of researching the image of salted fish products in the minds of Icelanders, general knowledge of salted fish and its history, and the experience of salted fish. The consumption frequency of salted fish, lightly salted fish and night-salted fish was also examined, as well as attitudes towards salted fish compared to lightly salted and night-salted fish. The survey was conducted in May 2019 and was published by 17,000 Facebook users, 18 years and older. A total of 505 people completed the survey.

There was a big difference in the participants' answers according to age. The results show that consumption of both fish and salted fish decreases with decreasing age. Only about 29% participants aged 18-29 eat salted fish once a year or more often than the corresponding proportion for the oldest group, 60-70 years, is about 94%. The main reason why participants do not eat salted fish is that they do not like it. Other reasons are that it is too salty, lack of supply, that there is little tradition for salted fish, and that fresh fish is preferred. In general, attitudes towards salted fish were quite positive and the experience of those who have bought salted fish in a restaurant, fish shop and grocery store was good. However, younger participants are generally more negative about salted fish and more likely to find the taste of salted fish bad than older ones. Knowledge and interest in salted fish also decreases with decreasing age, and the same applies to the purchase frequency of salted fish, lightly salted fish and night-salted fish. The results indicate that the taste of salted fish varies according to age. Older participants are more likely to want salted fish well salted and find it less salty than younger ones.

Saltfish has been intertwined with Icelandic history and food culture for centuries. The results of this survey, however, show declining knowledge, interest and consumption of salted fish in younger age groups. This development can be explained by an increased selection of foods, changed tastes, attitudes and habits. It is likely that the image of salted fish as a quality product will be affected and that great changes are taking place in the consumption of salted fish among Icelanders. In order to promote the consumption of salted fish, it needs to be better promoted and made more visible, not least among younger age groups, whether in canteens, supermarkets, fishmongers or restaurants.

Prepared dishes from salted fish

The aim of the project was to develop ready-made salted fish dishes and salted fish buns. By using, among other things, unused raw materials such as cuttings, increased value can be created from seafood. The aim was to sell these products in the Nordic countries, the Spanish market and in Iceland. Ektafiskur has a traditional production of salted fish and no additives are used in the production. Saltfish is a well-known product in Spain and the Nordic countries, and Ektafisk's current products have been well received in both Spain and Iceland. In order to maintain and / or increase its market share, it is necessary for the company to further develop its product line in line with today's consumer demands. Developments in salted fish products have led to greater convenience for consumers in line with changes in lifestyles in recent decades.

The aim of the project was to develop pre-made salt-cod dishes and fishcakes. By using un-utilized raw materials like cut-offs added value can be created. The goal was to market the products developed in this project in the Nordic countries, Spain and in Iceland. Ektafiskur produces traditional salted cod and do not use any additives. Salted cod is a known product in Spain as well as in the Nordic countries. The products from Ektafiskur have been well received both in Spain and Iceland. To maintain and / or increase its market size it is essential that Ektafiskur continue to develop new products with consumer demand in mind. The development of salted cod products has been increasingly towards consumer comfort and changes in life patterns in the last decades.

SafeSalt: Quality control of bacalao salt / SafeSalt: Quality control of salted fish salt

The aim of the project was to develop a rapid analysis method to assess the quality of salt used in salted fish production. The aim of the project was to minimize yellowing in salted fish. Experiments with the use of cod liver oil as a substitute for evaluating the fat development of metals showed promising results and it is necessary to transfer the results for cod liver oil to cod fillets. The results indicate that iron has a greater effect on fat development than copper. Emulsion was measured in fat at up to 5 ppm iron concentration in salt. It is necessary to examine the effect of copper and iron on the oxidation of protein in fish.

The objective of the project was to develop rapid test method to evaluate the quality of salt used in the production of heavily salted cod. This is done in order to reduce the risk of yellow discoloration in salted cod. Experiments where cod liver oil was used as surrogate material showed promising results and the next step is to extrapolate these results to cod filets. The results indicate that iron has stronger oxidizing effects on lipids compared to copper. Oxidation of lipids was detected at 5 ppm iron concentration in salt. Future research should aim at investigating the effects of copper and iron on protein oxidation in fish.

Production of salted fish in the Nordic countries. Variation in quality and characteristics of the salted products

The Nordic countries are the largest exporters of salted gadoid products, whereas countries in South ‐ Europe and Latin America are the biggest importers. In Norway, Iceland and Faroe Islands, cod is primarily used for the production. The characteristics of the salted fish, such as commercial quality and weight yield vary between the countries and between producers. These attributes are influenced by differences in catching methods, handling and salting methods. This report summarizes the variation in these procedures, and in addition, the market segmentation of salted products, from the different countries.

The majority of the world's salted fish production takes place within the Nordic countries, but the largest group of consumers is in Southern Europe and South America. Cod is the main raw material, but salted fish is also produced from other related species, such as saithe, ling, haddock and saithe. Properties of salted fish products, such as quality and utilization, vary between countries of production and producers. These variables depend on fishing methods, raw material handling and salting methods. The report is a summary of the variability in these factors between producing countries, as well as an assessment of their share in the salted fish markets.

The role and fate of added phosphates in salted cod products / Role and fate of added phosphate in salted fish

The aim of the project was to evaluate the fate of added phosphate in salted fish. It is clear that its amount decreases with effect and dehydration. The same goes for phosphates that are naturally present in fish muscle. Therefore, the total amount of phosphate in dehydrated products is usually lower than in fresh fish. However, it has been shown that added phosphates (di- and triphosphates) are found in both processed and dehydrated fish. However, it depends on the amount of phosphate added to the product and the salting processes used, ie. whether phosphate was added to the fish by injection or brine. Little or nothing is detected in dehydrated products if brine is used. Differences between processes can be due to the method of salting (spraying / pickling), the type and initial amount of phosphate added and the duration of action. Further research is needed to evaluate the effect of different salting processes on the fate of phosphate in salted cod muscles.

The aim of this study was to investigate the fate of added phosphates in salted cod products. The content of both added phosphates and naturally occurring phosphates, decreases during salting and rehydration. The final content in rehydrated fish (approx. 1-2.5% NaCl) is usually below values in the raw fish. However, di- and triphosphates are present both in salted and rehydrated products. The amount depends on the quantity of added phosphates in the product and on the salting procedures applied. It seems that lower contents are present in brined products than in injected products. Differences may depend on the method used for adding phosphates (injection / brining), phosphate type and, initial content of added phosphates in the muscle after pre-salting and finally on the curing time. Further studies are needed to get accurate information on the effects of different salting procedures on the fate of phosphates in salted cod products.

Measurements of trace metals in salt, salted fish and insoluble particles in diagnosis of the source of yellow discoloration in salted fish - carried out February to May 2009

Recently, there has been an unusual amount of yellow in salted fish meat, which reduces the quality and value of the production. Salted fish producers have suffered significant financial losses as a result. Salted fish, brine and foreign salt particles were analyzed for iron (Fe), cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), zinc (Zn) and manganese (Mn) to identify the cause. vandans. The concentration of metal was higher in yellow spots of salted fish than in white flesh, and a considerably higher amount of metal was found in brine, which caused yellow compared to other brines. Large amounts of metals were found in salt dust, which means that the dust can affect the formation of yellow spots in salted fish.

Recently several cases of yellow discoloration in salted cod have appeared. This yellow discoloration / yellow spots decreases the quality and value of the product and causes a significant financial damage for the producers. Salted cod, brine and insoluble particles from the salt were analyzed for iron (Fe), cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), zinc (Zn) and manganese (Mn) to investigate the cause of the problem. Metal concentration was higher in yellow spots from the salted cod compared to the white flesh of the cod. The metal concentration was also higher in brine that caused yellow discoloration compared to other brine. Considerable amount of metals were detected in insoluble dust particles from salt indicating that it might be the cause for the yellow discoloration in salted cod.

Process control for fishing, processing and processing of salted fish. Impact of raw material variables on the utilization and quality of salted fish

It was processed from data that has been collected at Vísi hf. and Þorbirni hf and the relationship between utilization and quality with fishing areas, fishing time, fishing vessel, cooling on board and changes in the process of action evaluated. It was found that fishing area had a significant effect on processing efficiency, but the difference between efficiency and quality according to fishing areas was smaller. Fluctuations in efficiency and quality were found to be seasonal and there were also differences between years. Changes to on-board cooling, i.e. the use of liquid ice instead of flake ice on board was not found to have a significant effect in the aforementioned manner. On the other hand, changes in the mechanism of action, ie injection, both utilization and quality. The content of the report was part of the project "Process control of fishing, processing and processing of salted fish".

Analysis of data collected by the fisheries companies Vísir and Thorfish revealed the effects of fishing grounds, season, fishing vessels, chilling methods on board and salting procedure on yield and quality of salted products. Effects of fishing grounds on processing yield were significant but curing yield and quality were less influenced. Variation in curing yield and quality were seasonal and differences between years were observed. Changes in chilling methods on-board, ie use of liquid ice instead of flake ice did not affect yield and quality of salted products. On the other hand, changes in the salting procedure did, when injection was added as the initial step in the process.
