Gæðasalt í saltfiskverkun / Quality salt for curing of salted fish
The main goal of the project was to use the geothermal sea in Reykjanes for the production of salt that can be used to produce high quality salted fish. A process will be developed to produce the salt with geothermal energy on site and to be able to control its chemical composition so that the correct effect of salted fish can be ensured. Salt extracted from the geothermal sea was compared with imported salt from the Mediterranean during the production of salted cod fillets with brine as pre-salting stage and dry salting at the end. The results showed that higher utilization was obtained in the salted fish processing with salt extracted from the geothermal sea, and that the processing took less time as the uptake of salt into the cod muscle was higher compared to the imported salt. Salt extracted from the geothermal sea was comparable in quality to the imported salt.
The aim of the project was to utilize raw material and energy from a geothermal brine to produce salt which can be used to increase the value in production of salted fish. Imported salt from Tunis was compared with the salt from geothermal brine, by producing salted cod from pickle salting followed by dry salting. The results showed that higher yield was observed in production of salted fish, by using salt produced from geothermal brine. Also curing took less time where the penetration of salt in the cod muscle was faster compared to the imported salt. The salt produced from geothermal brine is comparable with the imported salt.
