Pha-based biopolymer coatings for extending fresh produce shelf-life

Overview

Ex Seed introduces a revolutionary approach to extending the shelf-life of fresh produce using PHA-based biopolymer coatings. These coatings leverage the natural properties of Polyhydroxyalkanoates (PHAs) to form a flexible, moisture-retentive barrier on fruits and vegetables. By incorporating natural antimicrobial agents and antioxidants, the coatings are designed to reduce dehydration, prevent spoilage, and inhibit enzymatic browning, potentially extending the shelf-life of produce by up to 60-90 days. This technology ensures that the flavor, texture, and appearance of the produce remain unaffected.

Technical specifications

Key features:

• Moisture barrier: PHA coatings create a protective film that reduces dehydration and controls gas exchange.
• Antimicrobial properties: Incorporation of natural agents like essential oils to prevent microbial spoilage.
• Oxidation resistance: Antioxidants in the coatings inhibit enzymatic browning and oxidative damage.
• Versatile application: Suitable for various produce types, including apples, grapes, and avocados.
• Edible and safe: Formulated to meet food safety standards without altering sensory qualities.

Technology readiness level

Currently at TRL 5, this technology has progressed through laboratory validation and is undergoing further testing. The next steps include comprehensive shelf-life testing and regulatory approval processes to ensure compliance with safety standards and consumer acceptability.
