Desalting of dried salt-cured cod (Gadus morhua L.) without water renewal - 3D imaging of volume change
Desalting of dried salt-cured cod without water renewal with stirring every 12 h, and in stagnant water, was explored. Products of about 450 g were desalted for 96 h, followed by refrigerated storage in 120 h. During the desalting and subsequent storage, the change in weight, volume, salt-, and wate...
