Increased value of seafood with an emphasis on products for use in fish meal and fish oil production to product development
In 2008, gold nuggets were first caught in significant quantities, gold nuggets are very sensitive to salt uptake from fishing to processing. To reduce the salt content of the flour, broth from the processing was passed through a membrane filter set up by coarse centrifugation. This equipment was able to reduce the salt content from 11% to 4.5%. Membrane filtration equipment is expensive and has a high maintenance cost to run it in the process. Therefore, it was decided to change the procedure for fishing, storage and landing without changing the production process for flour processing, and this action has resulted in a reduction in the salt content of gold powder flour from 10 - 12 %, which is too high, down to 5 - 6 %.
Silvery lightfish was first caught 2008 near Iceland. Salt diffusion is a problem in silvery lightfish from catch to processing. To lower the salt content in fishmeal the stickwater was put through a membrane filter after coarse centrifuge, with this method the salt content was lowered from 11% down to 4,5%. The membrane filter system is expensive and maintenance cost is relatively high. These are the main reasons for changing procedure while catching, storing and landing without changing the fishmealprocess. This procedure has made salt content in silvery lightfish meal dropp from 10 - 12 % witch was to high down to 5 - 6 %.
