The Bottom Line
When defrosting as a result of changes in the colloidal structures of muscle tissue, tuna secretes a certain amount of juice. The bigger the loss of juice, the worse it will affect the taste of the cooked fish. The process of defrosting tuna does not tolerate warm, let alone hot water. At a water temperature of +35—+40°C, tuna protein loses its properties, absorbs hot water instead of lost muscle juice and mineral salts. Such fish takes on a stale smell, becomes loose, flabby and tasteless.
Thawed fish must not be frozen again, as this will result in a loss of nutrients, and the fish will taste bad. Tuna does not need to be completely thawed. Half-thawed tuna is juicier after cooking.
