ABSTRACT

Sardine (sardina pilchardus) fillets were marinated
by using three different marinade solutions prepared with vinegar (VM), grapefruit
juice (GM) and pomegranate juice concentrate (PM). All marinade formulations
contained 4% salt and 0.1% black pepper. Samples were stored at 4ºC for
28 days. Proximate composition, pH, acidity, salt content, moisture content,
penetrometer value, peroxide value and TBA value of marinated samples were evaluated
during storage of 28th days. Sardines marinated with grapefruit juice had the
highest pH value at each evaluation period. On day 28 the highest acid value
(0.94%) was obtained in VM samples and the lowest acid value (0.62%) was obtained
in GM samples. No significant differences in salt content were found between
marinade treatments at each evaluation period except day 28. At each evaluation
period GM samples had higher (softer in texture) and PM samples had lower penetrometer
values (harder in texture). PM samples had the lowest peroxide and TBA value
at each evaluation period. It’s concluded that pomegranate sauce could
be used as a functional marinade solution in sardine marination.

Key words: marination, sardine, grapefruit, pomegranate, vinegar.
