Quality Characteristics and Functional and Antioxidant Capacities of Algae-Fortified Fish Burgers Prepared from Common Barbel (Barbus barbus)‎

Abstract EN

Introduction.

Algae have been used as natural ingredients to produce new canned fish burgers prepared from minced flesh of common barbel.

In this research, the impact of the addition of Cystoseira compressa and Jania adhaerens at concentrations of 0.5, 1, and 1.5% w/v on the texture and sensory characteristics of fish burgers were investigated.

Results.

Compared to controls, fish burgers containing 1% algae had better texture and sensory properties (P < 0.05).

Also, these burger formulations had higher water and oil holding capacities as well as swelling ability, due to the important polysaccharides and dietary fibers contents of algae.

In addition, algae-supplemented burgers were characterized as having low L⁎, a⁎, and b⁎ values, which made the color appear to be paler.

Thanks to their high richness in pigments (chlorophylls and carotenoids) and polysaccharides, algae considerably enhance the antioxidant activities of the new ready-to-eat fish burgers.

So, Cystoseira compressa and Jania adhaerens could be used as nutritious additives to produce new fish-based products.
