Influence of partial sodium replacement on proximate composition, physical and sensory quality of marinated anchovy (Engraulis encrasicolus)

Abstract

Several studies are conducted to reduce the salt and various strategies are being developed for this purpose. Consumption of processed meat products is often preferred and salt is used for purposes such as ripening, flavouring, and preservation during their production. Many studies have shown that the excessive salt consumption has negative health effects and so that reducing sodium is important. In this study, the physical and sensory quality of the marinated anchovy produced with potassium salt instead of sodium salt was investigated. Anchovy used in this study was purchased from a local fish market as filleted. Anchovy fillets were transported to the laboratory in ice. Anchovy marinades were produced on the same day. The study consisted of 5 groups and all groups were produced the same day. During the marination acid and salt amounts and pH were monitored. Proximate composition (protein, fat, ash, moisture, sodium, and potassium), physical (colour measurement, cooking loss, texture profile analyses), and sensory (appearance-colour, odour, taste, texture, overall acceptability) quality analyses were performed on day 0. As a result, the best partial sodium replacement was obtained with 50% potassium salt by preserving the physical and sensory quality as in marinates prepared with only 100% sodium salt.
