by proteins during processing and helps the maintenance of
moisture and quality of fillets, in particular by reducing the
amount of thaw drip.
As regards minerals, sutchi catfish fillets have shown a
variable but high sodium content, probably due to the
polyphosphates added (Table 4). On the contrary, magnesium
levels were found to be lower than in other fish species
studied (Orban et al., 2006; Orban et al., 2007).
