Sensory Characteristics and Storage Quality Indicators of Surimi Franks Nutritionally Enhanced with Omega-3 Rich Flaxseed Oil and Salmon Oil
Surimi, a lean source of fish protein, is consumed worldwide in various forms. Considerable increase in U.S. consumption of surimi products was observed in the 1980s but tapered off in recent decades. Consumer demand for foods enriched with o-3 fatty acids including DHA and EPA has increased due to...

Most panelists (63%) indicated interest in purchasing this type product. Results indicate that the surimi franks were generally accepted by young adult consumers, which may indicate market potential of these types of products.

Surimi, a lean source of fish protein, is consumed worldwide in various forms.
