Proposals for the establishment of retail fish markets in Iceland / Public fish markets in Iceland - propositions

Why is it not common in Iceland for the public to be able to buy fresh fish on the quayside or at the fish market? Iceland is known for its large and healthy fishing grounds and fish products of high quality. Why not make more of an experience in connection with the fish, both for Icelanders and for tourists? Many people are interested in the idea of a fish market, but for some reason it has not been implemented. These proposals review the status of fish markets in Iceland and what "retail fish markets" can offer. Examples of fish markets abroad are taken, various ways of setting up a retail fish market are reviewed, and the main steps that need to be kept in mind when setting out are reviewed. Finally, an example is taken of the process of original idea work for the establishment of a retail fish market in Reykjavík. The authors hope that this summary will spark interest in and contribute to the establishment of fish markets for the general public across the country.  

There are currently no public fish markets in Iceland - why? Iceland is known for its rich fishing grounds and quality fish products. Why has the seafood experience been more exploited, for the Icelandic public as well as tourists? The idea of a public fish market greatest excitement among most people, however, it has not resulted in an up and running market. In these propositions the current situation in Iceland is reviewed as well as what is to gain by creating and running public fish markets. Examples are taken from fish markets abroad, different scenarios are illustrated and important steps in the preparation process discussed. Finally, example is given on the first steps in idea generation for a public fish market in Reykjavik. The authors aim for these propositions to encourage the establishment of public fish markets all around Iceland.

Freezing and thawing of Greenland halibut - experiments and CFD simulation

Freezing and thawing of halibut were studied experimentally and computerized thermodynamics (CFD) models. Whole pallets of semi-frozen halibut were placed in a cold store and the air temperature and halibut temperature in different places on the pallet were measured by thermometers. The time taken for the halibut to freeze from -10 to -5 ° C below -15 ° C ranged from one to four days depending on the location of the pallets. In thawing experiments, both individual bags and twenty bags, stacked on pallets, were examined in the temperature-controlled cold rooms of Matís and UI. The heating of a frozen product was mapped under conditions that may occur during unloading from freezer trawlers or 10 - 20 ° C air temperature. The results of the experiments were compared with the results of three-dimensional heat transfer models, and there was generally good agreement between them. At 10 p.m. storage at 12.6 ° C air temperature raised the temperature in individual bags from about -26 ° C to approx. ‐5 ° C. At such a long temperature load, the temperature in pallet bags rose from -22.5 ° C to from -17 to -3 ° C, which shows how homogeneous the heat distribution can be with prolonged heat load. The results of the CFD model showed that 10 m / s wind during loading significantly accelerates the thawing of frozen fish on pallets.   

Freezing and thawing of Greenland halibut was investigated with experiments and computational fluid dynamics (CFD) models. A whole pallet of half ‐ frozen halibut was put in a frozen storage and ambient temperature and fish temperature at different locations in the stack monitored. The required freezing time from ‐10 - ‐5 ° C down to ‐15 ° C was one to four days depending on the location within the stack. In the thawing experiments, both single, free standing halibut bags and twenty halibut bags stacked on a pallet, were investigated in an air climate chamber. The warm up of full ‐ frozen product was mapped under typical temperature conditions during unloading of products from freezer trawlers, ie at 10 - 20 ° C ambient temperature. A good comparison between the CFD simulation and experimental results was obtained. Fish temperature increased from ‐26 ° C to - 5 ° C inside single bags when thermally loaded for 10 hours at 12.6 ° C ambient temperature. Equally long temperature abuse for the whole pallet, initially at ‐22.5 ° C, resulted in a very inhomogeneous temperature distribution from ‐17 to ‐3 ° C. The results from the CFD modeling showed that 10 m / s wind during unloading seriously accelerates thawing of frozen fish.

Matís at the exhibition Matur-inn in Akureyri

The exhibition FOOD-INN 2009 will be held in the Sports Hall in Akureyri on the 3rd and 4th of October. The exhibition is the largest event in the activities of the association Matur úr Eyjafjörður - Local food, but the last exhibition was held in the autumn of 2007 at the Vocational School in Akureyri and was well attended.

The exhibition was attended by about 10 thousand people and it was clear immediately after it that the exhibition would be moved to another building. Therefore, the Sports Hall was now chosen and it will truly be turned into a dining hall and harvest house this first weekend of October. Matís will have a booth at the show and welcomes everyone to visit.

An event that will attract thousands of visitors
As before, it is planned that the exhibition will be both diverse and a highlight in Nordic food culture. There will be exhibition areas for companies and NGOs, there will also be a market area where it is ideal to sell the autumn harvest or anything else related to food and food culture. The exhibition area will also have fun competitions for visitors to attend, seminars (workshops) on various aspects of food and food culture, and finally a seminar on Icelandic food will be held in connection with the exhibition. At the same time, it will be information and entertainment that will undoubtedly attract thousands of visitors.

Emphasis is placed on the participation of as many companies related to food culture as possible, and the aim of the exhibition's relatives is to continue where the well-closed exhibition 2007 left off, to show and prove how important food plays in the North, from production and processing to food. - and service.

Opening hours for both days are from 11.00 to 17.00.

Admission to the exhibition is free.

Addition of proteins to fish

Master's lecture in food science at the Faculty of Food and Nutrition, School of Health Sciences, University of Iceland. Matís, meeting room on the first floor, Skúlagata 4, tomorrow, Tuesday 29 September at 16-17.

Magnea G. Karsdóttir gives a talk on his MS project.

„Application of additives in chilled and frozen white fish fillets- Effects on chemical and physicochemical properties“

Supervisor:               Sigurjón Arason, Associate Professor of Food Processing

Co-supervisor:           Guðjón Þorkelsson, Associate Professor of Food Processing

Master's Degree Committee:      Sigurjón Arason, Guðjón Þorkelsson and

Examiner:                  Hörður G. Kristinsson, Division Manager at Matís

The project is funded by the AVS Fisheries Research Fund, the Technology Development Fund and the Nordisk InnovationsCenter.

S amantekt - MS project.
The main objective of the project was to study the admixture of excipients, in particular fish proteins, and their effect on the chemical and physical properties of chilled and frozen fish fillets. Fresh fillets of saithe and cod and lightly salted fillets of cod were sprayed with some protein mixtures and compared with untreated fillets and fillets that were spray salted (1.5% and 4%). The fillets were then stored at + 2 ° C and -24 ° C for varying lengths of time. 

The factors examined were utilization, water resistance, chemical composition and T2 transversal relaxation hours. The addition of the proteins increased the weight gain during injection compared to salt-injected fillets, but to varying degrees depending on the type of protein. The added proteins also had a significant increase in post-storage utilization and a decrease in the amount of drip compared to untreated and spray-salted fillets.

The most influential proteins were hydrolyzed fish protein (FPH) and membranous fish protein (HFP), but they also gave relatively better overall utilization of cod fillets. Mixing with proteins and / or salt, on the other hand, had little effect on the water resistance of the fillets, but it was expected that the water resistance would be better compared to untreated fillets.

The mixture that had the most positive effect on water resistance was FPH. The addition of protein to saithe and cod fillets has, on the whole, a positive effect on improving the stability and quality of the fillets, but there is a need to develop and the best blending methods with regard to the raw material.

The cod fillets showed better results compared to the saithe fillets. The saithe fillets seem to be much more sensitive to injection and freezing than the cod fillets, but loosening is a known problem with saithe fillets. The addition of fish proteins is an option that is worth exploring further with the aim of increasing the utilization and value of seafood.

Is it possible to reduce waste in the production and distribution of food?

Matís employee, Þóra Valsdóttir, will give a talk on this topic at an open meeting tomorrow, Thursday 24 September at 15-17 at the Grand Hotel.

The annual turnover in the meat industry in Iceland is estimated at ISK 25 billion. It is estimated that at least 5% or 1250 million will be lost due to shrinkage that occurs before the product reaches the consumer. Therefore, there is a lot of work to be done if this shrinkage can be reduced.
What can be done to reduce waste in food production and distribution? What does improved treatment and information flow between parties in the value chain yield?

The Confederation of Icelandic Industries, Tækniþróunarsjóður, Norðlenska, Sláturfélag Suðurlands, Kaupás, AGR, Matís and Rannsóknarsetur verslunarinn, call for an open meeting where the results of a development project on this subject will be presented, where the meat industry was taken as an example. The results can be applied to other sectors of the food industry.

Location: The center, Grand Hotel Reykjavík
Time:
 Thursday 24 September at 15-17

Agenda:

  1. Benefits of improved food handling and knowledge of food. Þóra Valsdóttir, food scientist, Matís.
  2. Use of information systems to improve production management and reduce inventory costs. Einar Karl Þórhallsson and Hlynur Stefánsson, AGR engineers.
  3. Product management of fresh food - precedent and experience. Emil B. Karlsson, director of the Research Center of the store.
  4. General discussion.

Moderator: Davíð Lúðvíksson, Director of Policy and Innovation, SI.
