Summary

Desalting of dried salt-cured whitefish is traditionally performed by immersion in water up to 48 h. This process reduces the salt content from approximately 20 to 2%. Alternatively, the fish is immersed in water for a few hours and then cooked. The cooking causes a crumbled product that fits traditional dishes found in Caribbean. In this study the weight changes, moisture, and salt content of dried salt-cured saithe, applying short time for immersion followed by cooking, was explored. Immersion for 2 min or 2 h, followed by three cooking sessions, with water exchanges in between, resulted in salt contents of 6-9%. Immersion in 16 h and cooking resulted in salt contents of 3-4%. Cooking for 20 min resulted in lower salt content than cooking just to boiling temperature. Compared to the traditional desalting, the two-step procedure with 16 h immersion and 20 min cooking, reduced the total preparation time significantly.
