Upcycled Eggplant Peel Extract Enhances Antioxidant Properties but Reduces Palatability in Dairy Desserts

Incorporating upcycled eggplant peel extract into dairy desserts can significantly boost their antioxidant and phenolic content, but may negatively impact consumer acceptance.

Turkish Journal of Agriculture - Food Science and Technology · 2023

Key Findings

01Higher concentrations of fenugreek gum and eggplant peel extract improved syneresis percentage, indicating reduced water release and better storage stability.
02Fenugreek gum addition positively correlated with increased storage stability.
03Eggplant peel extract increased monomeric anthocyanins, total phenolics, total flavonoids, and antioxidant activity.
04Consumer acceptance scores for products with eggplant peel extract were reported to be very low.

Application

Design takeaway

When using upcycled ingredients for functional benefits, prioritize sensory testing early in the design process to balance nutritional enhancement with consumer preference.

How to apply

When developing new food products or reformulating existing ones with functional ingredients derived from food waste, conduct thorough sensory analysis alongside nutritional assessments.

Project actions

01Consider using food waste as a source for functional ingredients in your design project.
02Plan for comprehensive sensory testing to understand user perception.

Method & Evidence

AimTo investigate the effects of fenugreek gum and eggplant peel extract on the physicochemical, storage, bioactive, and sensory properties of a dairy dessert.

MethodExperimental design with varying concentrations of additives.

ProcedureRice pudding was formulated with different levels of fenugreek gum (0%, 0.2%, 0.4%) and eggplant peel extract (0%, 0.25%, 0.5%). Various properties including total soluble solids, pH, color, syneresis, storage stability, total phenolic content, antioxidant activity, flavonoid, anthocyanin content, and sensory acceptance were measured.

ContextFood product development, dairy desserts, ingredient innovation.

Variables

IV["Concentration of fenugreek gum","Concentration of eggplant peel extract"]

DV["Physicochemical properties (e.g., total soluble solids, pH, color, syneresis)","Storage stability","Bioactive compounds (phenolics, flavonoids, anthocyanins)","Antioxidant activity","Sensory acceptance"]

CV["Base dairy dessert formulation (rice pudding)","Storage conditions"]

Strengths & Limitations

Strengths

+Investigated a wide range of properties, from physical to sensory.
+Included multiple concentrations of two different additives.

Limitations

The specific type of food waste used and the processing methods can significantly alter the final properties and consumer acceptance.

Reliability & validity

The study's reliability could be enhanced by repeating measurements and using standardized analytical methods. Validity is supported by the comprehensive evaluation of multiple properties and the use of a standard sensory scale.

Think critically

How can designers mitigate the negative sensory impacts of functional, upcycled ingredients to achieve both health and market success?

Design Principles

"Maximize resource utilization by valorizing food byproducts, but validate sensory impact to ensure product success."

This research highlights a trade-off in using food waste streams for functional ingredient development. While it offers a sustainable approach to valorize byproducts and enhance nutritional profiles, designers must carefully consider the sensory implications to ensure market viability.

What This Means for Your Design

Using parts of vegetables like eggplant peels that are usually thrown away can make food healthier by adding antioxidants, but people might not like the taste as much.

How to use in your project

Paragraph starter

Research indicates that while upcycled ingredients like eggplant peel extract can enhance the nutritional profile of food products by increasing antioxidant content, their incorporation may lead to a significant decrease in consumer acceptance due to altered sensory attributes. This suggests a critical need for careful formulation and sensory evaluation when designing with sustainable food waste streams.
