1 P-NDV: Provian NDV; 2 Salt levels in weight % of the fresh fish, ND: Not determined. 3 Calculated levels of NaCl and KCl are according to measured total levels of Na and K (subtracted the background levels of Na+ (59 mg/100 g) and K+ (363 mg/100 g) in farmed Atlantic salmon) [31]. Salt uptake is the level of absorbed salt in CS salmon relative to the added amount of the respective salts. 4 Levels were calculated according to added levels of Provian-NDV containing 100 % K-acetate. 5 Level of KCl is provided by added Nutek and assumed to be the same as in Product no. P3. 6 Commercial CS salmon produced using NaCl and the traditional in-house dry salting and smokery process.
