Citrus-derived coatings to extend shelf-life of fresh produce

Overview

Our innovative solution utilizes citrus-derived coatings to significantly extend the shelf-life of fresh fruits and vegetables. By forming a protective biofilm barrier, these coatings reduce respiration rates and moisture loss, which are critical factors in maintaining the freshness and quality of produce. The use of pectin and citrus fibers, both naturally occurring polysaccharides, ensures that the solution is renewable, biodegradable, and edible, making it an environmentally friendly option for food preservation.

Technical specifications

• Film-forming properties: The coatings provide a strong, protective layer that shields fruits and vegetables from environmental factors.
• Natural composition: Utilizes CP Kelco pectin and citrus fiber, which are derived from the cell walls of plants, ensuring bio-compatibility.
• Barrier protection: Acts to control respiration and moisture loss, key elements in extending shelf life.
• Testing and validation: Future validation includes characterizing biofilm properties such as thickness, mechanical strength, permeability, and thermal stability, and comparing preservation efficacy against a non-coated control group.

Technology readiness level

This technology is currently at TRL 3. We are collaborating with Kraft-Heinz to co-develop and test the solution, focusing on assessing the performance and application methods of these coatings on various fruits and vegetables.
