Enhancement of the nutritional status and quality of enrcihed silver carp (Hypophthalmichthys moltrix) sausage by fish oil

The effects of adding refined cod liver oil- rich in omega 3- in three forms (fish oil, O/W emulsion, gelled oil-in-water emulsion) to sausage from silver carp (Hypophthalmichthys moltrix) was investigated. In this regard, such properties of the sausage as its physicochemical, sensory, microbiological, texture, color, cooking loss and oxidative stability of enriched sausages were assessed. The results of proximate composition analyses showed that there was no difference between enriched formulated fish sausage (p> 0.05). pH ranged from 6.52 to 6.72 and decreased during storage. Enrichment of fish sausage caused to higher ω-3 PUFAs content, especially EPA and DHA, and decreasing significantly the ω-6/ω-3 ratio from 22.3 to 9.85. The control and fish oil treatments showed significantly higher thiobarbituric acid value during storage (p
