Valorizing Fruit By-products: Craft Jelly Candies with Enhanced Antioxidant Properties

Incorporating fruit by-products like sea buckthorn pomace into confectionery can significantly boost antioxidant content and nutritional value while reducing waste.

The Annals of the University Dunarea de Jos of Galati Fascicle VI – Food Technology · 2025

Key Findings

01Sea buckthorn pomace incorporation significantly increased antioxidant content, with DPPH radical scavenging activity reaching up to 91.71%.
02Optimal sensory acceptance and texture were achieved with 1-2% sea buckthorn pomace, while higher concentrations led to excessive tartness and undesirable textural changes.
03The use of quince puree and sea buckthorn pomace enhanced the nutritional profile and contributed to waste valorization.

Application

Design takeaway

How to apply

When developing new confectionery or snack products, investigate local fruit processing waste streams for potential ingredient inclusion. Conduct small-scale sensory trials to determine optimal inclusion levels before scaling up.

Project actions

01When choosing by-products, research their nutritional and functional properties.
02Plan for sensory testing early in the design process to get feedback on taste and texture.

Method & Evidence

AimTo investigate the feasibility and impact of using quince puree and sea buckthorn pomace by-products in the development of craft jelly candies, evaluating their nutritional, physicochemical, and sensory qualities.

MethodExperimental design and sensory analysis

ProcedureFive jelly candy formulations were created with varying percentages of sea buckthorn pomace powder (0-4%). These formulations were then analyzed for their nutritional composition (fiber, polyphenols), antioxidant capacity (DPPH, hydrogen peroxide scavenging), and physicochemical properties. Sensory evaluation was conducted using the Check-All-That-Apply (CATA) method to assess texture, taste, and appearance.

ContextFood product development, confectionery manufacturing

Variables

IVPercentage of sea buckthorn pomace powder in jelly candy formulations.

DVAntioxidant content (DPPH, hydrogen peroxide scavenging), fiber content, total polyphenol content, sensory attributes (texture, taste, appearance).

CVQuince puree type and concentration, other base candy ingredients (sugar, pectin, water), processing methods.

Strengths & Limitations

Strengths

+Utilizes by-products, promoting sustainability.
+Quantifies nutritional and functional improvements.
+Includes sensory evaluation for consumer relevance.

Limitations

The sensory panel might not represent a diverse consumer base, and the study did not explore the long-term stability of the candies.

Reliability & validity

The study uses established analytical methods for nutritional and antioxidant analysis, contributing to its validity. Replicating the sensory evaluation with a larger, more diverse panel would enhance reliability.

Think critically

How might the processing of the by-products themselves (e.g., drying, grinding) affect their nutritional content and subsequent impact on the final product?

Design Principles

"Valorize by-products by integrating them into new product designs to enhance nutritional and functional properties while minimizing waste."

This approach offers a pathway for the food industry to develop more sustainable products by transforming waste streams into valuable ingredients. It addresses both resource efficiency and consumer demand for healthier food options.

What This Means for Your Design

You can make candy healthier and reduce waste by adding fruit leftovers, like the skin and seeds from making juice, but you have to be careful not to add too much or it will taste bad.
