Many people enjoy a fillet of cod, but you may not know that the filet only constitutes 40% of the fish and that the rest such as the head and intestines are often disposed of leaving the companies involved with a great expense? When you consider we need to find ways to make the most of the resources that are available and ensure we produce more food for the world’s growing population, this wasteful process needs to change. But one of the hurdles that prevents exploitation of the cod waste side-streams and the development of more valuable products is the fact that the side-streams deteriorate very quickly.
A prerequisite for exploiting the side-streams for more valuable purposes such as nutritional ingredients is that the side-streams are of high quality. Ensuring this, requires proper logistics and infrastructure so that the side-streams are fresh. But now a European project WaSeaBi , has brought together three research institutes, one industry cluster and nine companies from Denmark, Sweden, Belgium, France and Spain respectively together to solve this challenge. One of the companies participating in the project is Royal Greenland, who among other things are providing raw-materials like side-streams from their Nutaaq cod.
This cod product is particularly interesting to work with in this context because it is extremely fresh. In fact, there is a maximum time span of two hours from the live cod leaves the sea until it is frozen in the factory. This means that there is a good basis for exploiting the side-streams for developing other products, ingredients or the like.
The unique freshness of the cod is achieved through close collaboration with local fishermen combined with an innovative processing method. After the fish is caught, the fishermen empty their net traps into Royal Greenland’s net cages nearby. In due time, a specially designed well boat collects the live cod directly from the net cage, where they are kept in seawater wells and where the water is continuously replaced with new seawater to give the cod the best possible conditions. The cod is then unloaded into large net enclosures in the fjord right outside the factory. When the factory is ready, the cod is transported directly into the factory for processing. This means that the live cod stay in the sea right up until the point when the factory is ready to process them.
Samples of side-streams including heads, frames and intestines from the Nutaaq cod waste have been collected this autumn in the town of Maniitsoq in Greenland. The composition and quality of these side-streams are currently being analysed at the Technical University of Denmark and at Chalmers University of Technology in Sweden. Results from these analyses will form the basis for the development of methods to protect the side-streams against deterioration if needed and of technologies to produce new ingredients for food and feed from these side-streams.
The cod waste project has a total project budget of €4,158,214 and receives €3,197,422 in funding from the Bio Based Industries Joint Undertaking (JU) under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 837726. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and the Bio Based Industries Consortium. The project period is May 2019 – May 2023.
