Effect of salt reduction and washing process of fish pulp on quality characteristics of Serra Spanish mackerel (Scomberomorus brasiliensis) fish burgers for school meals

Abstract

The objective of this study was to investigate the effect of salt reduction and washing process of fish pulp on chemical composition, cooking characteristics, color, texture and microbiological quality of Serra Spanish mackerel fish burgers (Scomberomorus brasiliensis) for school meals. The variables studied were: fish pulp (full and washed), table salt concentration (1.5 and 0.75 %), and monosodium glutamate (0 and 0.3 %). The samples were subjected to physicochemi- cal and microbiological analyses. Although significant differ- ences were observed in the parameters analyzed, they were influenced by the type of pulp used rather than the salt reduc- tion.Theresultsindicatedthatitispossibletoreduce50%salt in fish burgers and maintain product quality.
