The microstructure of the muscle was significantly altered during
salting. The high increase in salt content led to shrinkage of
muscle fibers and enlargement of the inter-cellular space (Figs. 3
and 5). During rehydration, the fibers swelled again up to a similar
cross-sectional area as in the fresh fish (Figs. 4 and 6), whereas the
inter-cellular space remained larger
