Use of hydrogen peroxide and carbonate/bicarbonate buffer for soaking of bacalao (salted cod)
Fillets of cod (Gadus morhua), brined and then dry-salted with NaCl, were cut into portions and desalted with different solutions: carbonate/bicarbonate buffer pH 9.5, tap water, or solutions of 0.25 or 1% hydrogen peroxide. The yield was measured after desalting. The moisture content, water-holding...

Summary: | Fillets of cod (Gadus morhua), brined and then dry-salted with NaCl, were cut into portions and desalted with different solutions: carbonate/bicarbonate buffer pH 9.5, tap water, or solutions of 0.25 or 1% hydrogen peroxide. The yield was measured after desalting. The moisture content, water-holding capacity, whiteness, firmness, total volatile basic nitrogen content and microbial load were determined during cold storage. When a pH 9.5 carbonate/bicarbonate buffer solution was used during the early hours of desalting, the yield increased and the product presented better protein functional quality but was highly perishable. When 0.25-1% hydrogen peroxide was used during the early hours of desalting, the microbial content of the end product was considerably lower, as was the yield; the firmness and surface whiteness of the product were improved but its water-binding properties were unaffected. © Springer-Verlag 2005.
