Optimization of salmonid bleeding and its effect on product quality and environment

There is a great deal of experience and knowledge in the best way of bleeding cod, but residual blood in fillets is considered a quality problem; both in terms of appearance and as a result, residual blood causes storage during storage. One of the goals of the project was to improve the bleeding of salmonids, but it was not possible to complete it as no further funding was available. 

Salmon farming is an environmentally friendly protein production and it is important to minimize the environmental impact of the production. One of the goals of the project was to develop equipment for purifying processing water before it is returned to nature. New equipment has been installed at Arnarlax, but the company is a partner in the project.

Preliminary studies were carried out to develop future value from materials in processing water, and the task of the future will be to complete that work.
