Lemon and Vinegar Marinades Enhance Consumer Acceptance of Common Carp Sticks

Utilizing common carp, a readily available freshwater fish, in a processed stick format with lemon or vinegar marinades can overcome sensory barriers and improve consumer appeal.

NAJFNR · 2025

Key Findings

01No significant sensory difference was found between sticks marinated with vinegar or lemon.
02Lemon marinade exhibited an antimicrobial effect, reducing microbial load.
03Both types of fish sticks were rated highly by panelists for sensory appreciation.
04The nutritional value of the fish sticks was considered good.

Application

Design takeaway

Incorporate acidic marinades like lemon or vinegar when developing processed fish products from species with potential sensory challenges to improve consumer acceptance and shelf stability.

How to apply

When designing new fish products, consider using acidic marinades to mask potential off-odors and improve microbial safety, thereby increasing the appeal of less common fish species.

Project actions

01Consider using readily available but underutilized local ingredients in your design projects.
02Investigate how processing techniques can overcome inherent material limitations.

Method & Evidence

AimTo develop and evaluate common carp fish sticks as an appealing alternative product to increase freshwater fish consumption, assessing their nutritional and sensory properties.

MethodExperimental design with comparative analysis

ProcedureCommon carp flesh was marinated for 12 hours in either vinegar or lemon juice. The marinated fish was steam-cooked, flaked, and mixed with binders (potato flakes, spices, oil, milk powder) to form a dough. This dough was shaped into sticks, coated (flour, egg, breadcrumbs), and deep-fried. Both marinated and unmarinated carp were analyzed for nutritional content, and the final sticks were assessed for microbiological and sensory attributes by a panel.

ContextFood product development, sustainable food consumption, fisheries utilization

Variables

IV["Type of marinade (vinegar vs. lemon)"]

DV["Sensory appreciation scores","Microbial load","Nutritional value"]

CV["Fish species (common carp)","Marination time and temperature","Cooking method (steam, deep-fry)","Other ingredients (potato flakes, spices, oil, milk powder, coating)"]

Strengths & Limitations

Strengths

+Directly addresses a practical problem of increasing fish consumption.
+Combines nutritional and sensory evaluation for a holistic product assessment.

Limitations

The taste panel was likely small and may not represent a wider consumer base. The study focused only on two specific marinades.

Reliability & validity

The use of standardized analytical methods for nutritional and microbiological testing contributes to reliability. Sensory evaluation, while subjective, was conducted with a panel, providing a degree of validity for consumer preference.

Think critically

How might the antimicrobial effect of lemon juice impact the overall shelf-life and safety of these fish sticks in a commercial setting, and what further testing would be required?

Design Principles

"Sensory enhancement through acidification can unlock the market potential of underutilized resources."

This research demonstrates a practical approach to increasing the consumption of underutilized freshwater fish species. By transforming a potentially less desirable raw material into a palatable product, designers and food technologists can address market gaps and promote sustainable food sources.

What This Means for Your Design

You can make less popular fish, like common carp, taste better and be safer to eat by marinating it in lemon or vinegar before turning it into fish sticks.

Paragraph starter

Research by Sabba et al. (2025) indicates that common carp fish sticks, when marinated with either lemon or vinegar, achieve high consumer acceptance and good nutritional value, suggesting that acidic marinades can effectively enhance the palatability and marketability of underutilized freshwater fish species.
