New formulation for producing salmon pâté with reduced sodium content.

Area of Science:

• Food Science
• Nutritional Science
• Public Health

Background:

• Reducing sodium intake is crucial for public health.
• Traditional salt (sodium chloride) in processed foods contributes significantly to high dietary sodium.
• Developing healthier alternatives for salt reduction in popular food products like pâté is essential.

Purpose of the Study:

• To investigate a novel salmon pâté formulation with reduced sodium content.
• To evaluate the efficacy of Saltwell®, a natural salt mixture, as a sodium chloride substitute.
• To assess the impact of sodium reduction on microbiological, sensory, and chemical properties of salmon pâté.

Main Methods:

• Formulation of salmon pâté with three different sodium concentrations using partial substitution of sodium chloride with Saltwell®.
• Microbiological analyses to assess microbial activity and safety.
• Sensory evaluation by a trained panel to determine differences in attributes like texture and flavor.
• Chemical analyses to quantify sodium content.

Main Results:

• Replacing 80% of sodium chloride with Saltwell® resulted in a 22% reduction in overall sodium content.
• No adverse effects on microbial activity were observed.
• Minor, weakly significant differences were detected in sensory attributes including coherent texture, saltiness, and canned fish flavor.

Conclusions:

• Saltwell® is a viable alternative to sodium chloride for producing reduced-sodium salmon pâté.
• The substitution effectively lowers sodium content without compromising product safety or significantly affecting sensory quality.
• This approach offers a promising strategy for developing healthier seafood products.
