Description
Summary:Rigor mortis of cultivated Atlantic salmon (Salmo salar) be-gan to set in 8h after death and was fully resolved 60-70h after death during storage at 0°C. Maximum muscle contrac-tion was observed 24–30h after death. ATP content decreased from 7.25 to 0.14 to 0.09 µmol/g fish from pre-rigor mortis to in-rigor mortis to post-rigor mortis state. The inosine and hypoxanthine contents increased from 0 to 1.20 to 4.06 mol/ g fish and from 0.08 to 0.33 to 0.84 mol/g fish during 60h storage, respectively, during 60h of storage at 0C. Postmor-tem changes affected salt uptake. The equilibrium salt con-centrations of pre-rigor, in-rigor and post-rigor mortis salmon were 0.53, 0.66 and 0.75 g/g salt-free solids, respectively, in a 20 % (w/v) sodium chloride solution at 10C.
