Preference and perception of low-sodium burger

Area of Science:

• Food Science
• Nutrition Science
• Consumer Studies

Background:

• Existing sodium reduction policies face challenges in practical application and effectiveness.
• Consumer preference and field cooperation are crucial for successful sodium reduction strategies.

Purpose of the Study:

• To develop a low-sodium burger considering both field applicability and consumer preferences.
• To assess the impact of gradual sodium reduction on burger taste and consumer acceptance.

Main Methods:

• Focus group and in-depth interviews with nine food industry professionals to identify practical sodium reduction methods.
• Development of a low-sodium burger using adjusted salt ratios in the sauce.
• Consumer preference evaluation of low-sodium burgers among 51 college students.

Main Results:

• Professional interviews suggested gradual sodium reduction is desirable.
• Low-sodium burgers (H1 and H2 groups) showed a 9.3-11.9% decrease in sodium content compared to the control.
• Consumer preference analysis indicated higher acceptance for burgers with 9.3-11.9% sodium reduction, with no significant impact on overall taste.

Conclusions:

• A gradual, approximate 10% sodium reduction in burgers can enhance consumer preference without compromising taste or quality.
• The developed low-sodium burger is potentially applicable in the franchise foodservice industry.
• Practical, gradual sodium reduction strategies can be successfully implemented in the food industry.
