Abstract
The objective of this study is to investigate the preservative characteristics of ascorbic acid (A) on the color, texture and fatty acids (FA) of cold-smoked fish. The fish (~250 g) were treated with six different formulation of brine prepared with 10% salt, which is the control(C), treated with 0.4% NaNO2 (N4), 0.2% NaNO2(N2) and only 2.5% A and their combinations (N4A, N2A). The sample groups were cold smoked, then stored at ±4°C and analyzed for 15 days intervals. The results showed that ascorbic acid did not have any negative effect on color, texture or sensory characteristics while there were significant preservative effects on FA. The most stable groups were N and A combinations. The PUFA (Polyunsaturated FA), PUFAω-3, PUFAω-6 and UFA (Unsaturated FA) of N4A and N2A were higher than group C and A. Accordingly, it is expected that, in terms of PUFAω-3 and PUFAω-6, the combination of N and A can contribute to the lipid stability.
