the developments of methods for
restructuring low-value cuts and trimmings to
improve their appearance, flavour and texture and
to enhance the market value. Then an alternative
process involves obtaining a fish paste by
mechanical separation of the flesh and then
preparing restructured fish products with high
economic and nutritive value (Ramírez et al.,
2007).
Restructuring yields fish products with high
commercial value from different sources: noncommercial
fish species, fish with size smaller
than commercial (such as shrimp by-catch) and
trimmings from fillets of commercial fish species.
Although several methods of restructuring have
been developed, the most commonly used include
cutting, tumbling and massaging, with or without
vacuum (Bruschi, 2001; Mira and LanferMarquez,
2005; Ramírez et al., 2007).
