| Abstract: | Fatty fish are a valuable dietary source of proteins and of polyenoic fatty acids from
the n-3 family. Smoking may affect the state of lipids and proteins due to heating and the
reactivity of smoke components, predominantly phenols. The aim of this work was to investigate
the effect of smoking in mild conditions on lipid oxidation and lysine availability in
Atlantic mackerel fillets and sprats. There was large variability in the results regarding the
state of the lipids and proteins in individual defrosted raw mackerel fillets taken from the
same batch. No correlation was found between the degree of lipid oxidation and the contents
of lipids in the thawed fillets. The ranges of the peroxide value and anisidine value were
considerably high. Hot and cold smoking did not affect the peroxide value of mackerel fillets,
while in smoked sprats it was much lower than in the thawed fish. Smoking did not cause any
decrease in lysine availability, although the anisidine value increased about twofold in smoked
mackerel and fourfold in smoked sprats. The contents of phenols were similar in the skins of
the analyzed samples of all assortments of smoked fish and ranged from 19 to 24 mg/100 g.
The phenol content in the meat of the smoked sprats was only 20% lower than that in the skin. |
