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.

Processing of nephrops lobster claw meat

The project was about the utilization of previously unused raw materials from seafood, which is lobster meat. The project involved both the processing of lobster claw marrow and the processing of marrow products. Processing processes were defined using utilization factors and raw materials were studied. The processing properties of the marlin were studied and tested in two products. Estimated margins were measured to assess the feasibility of complete processing of lobster marrow products. Efforts will be made to make full use of all the raw materials that come from lobster clones so that value creation is maximized in the processing of food related to lobster claws from lobster claws.

A process for isolating mince from nephrops lobster claws was developed and the product tested for microbial, chemical and sensory quality. The mince was tested in two ready to eat products. Production cost, yield and gross margin were calculated in order to determine the feasibility of starting up an industrial scale production of the mince as well as for production of ready to eat products.

Overview on fish quality research - Impact of fish handling, processing, storage and logistics on fish quality deterioration

The short shelf life of fish is a limiting factor in the export of fresh fish products from Iceland. The initial quality of raw materials, methods of cooling, processing, packaging and conditions during storage and transport are discussed, as well as the effects of all these factors on the freshness and shelf life of fish products. Temperature control is very important to maintain the quality of the fish. Pre-processed fillets have been used to lower the pre-packing temperature. However, care must be taken that the pre-cooling technology does not endanger the microbial condition of the product and thus causes it to be damaged earlier after packaging. The synergistic effects of supercooling and aerated packaging (MAP) can significantly extend the freshness period and shelf life of fish products. Furthermore, packaging methods are examined, including new, more environmentally friendly packaging. Finally, the effect of transport routes of fresh fish products on their final quality to consumers in the market is discussed. This report provides an overview of the research of the Fisheries Research Institute and Matís ohf over the past three decades on the subject. Furthermore, it is discussed how these results can benefit the fishing industry.

The limited shelf life of fresh fish products is a large hurdle for the export of fresh products from Iceland. The influence of raw material quality, cooling methods, processing, packaging and storage conditions on freshness and shelf life extension is discussed. Temperature control is important to maintain fish quality. Pre-cooling of fillets in process has been used to lower the temperature prior to packaging. However, the cooling technique applied should not compromise the microbiological quality of the product and render it vulnerable to faster spoilage postpackaging. Synergism of combined superchilling and modified atmosphere packaging (MAP) can lead to a considerable extension of the freshness period and shelf life of fish products. Further, alternative and environmentally-friendly packaging methods are considered. Finally, the impact of transportation mode of fresh fish products on their resulting quality is examined. This report provides an overview of the findings on fish research carried out at Matís (Icelandic Fisheries Laboratories) over the last three decades and further discusses their practicality for the fish processing industry.

Isolation and processing of bioactive peptides from underutilized species of marine organisms - preparation and formation of networks

In this preliminary project, preparations were made for the establishment of a center in the Westman Islands that will specialize in research, processing and marketing of products made from by-products of fish processing and underutilized species. The long-term goal is to start processing bioactive substances from seafood. To bridge the gap between raw material sourcing and specialized processing of bioactive substances, the center was expected to embark on projects that increase the value of by-products. A network was formed to ensure the development of skills and knowledge regarding the processing of bioactive and pharmaceutical forms. The network brought together both foreign and domestic researchers and stakeholders. Applications for collaborative projects were sent to Nordforsk and the NORA Fund, as well as applications to the ACP Fund with companies in Iceland for slag digestion processing, value added and product development. These emphases were also successfully incorporated into proposals for the Growth Agreement of the South, which was signed in October 2006. The collaboration will continue and the aim is to establish large international research projects on bioactivity in seafood. Special attention is paid to the 7th EC Framework Program. The group is also working on reviewing the status of each individual's knowledge and skills, and subsequently aims to publish a peer-reviewed review article on bioactive peptides in seafood.

The foundation of an R&D center in Vestmannaeyjar for utilizing marine byproducts by turning them into commercially viable products was prepared. The aim of the center is to establish state of the art of the processing of bioactive compounds from marine by-products and underutilized species. A small Nordic knowledge network to build competence and skills regarding bio processing of bio- and pharmaceutically active compounds was also established. The network now consists of scientists and industry related stakeholders from Norway, Scotland, Finland and Iceland. The network partners have decided to work together on joint international grant applications for R&D projects in marine bioprocessing. The network is currently comparing resources of knowledge and subsequently the aim is to publish a peer reviewed state of the art review of marine bioactive peptides.
