Degradable Smart Preservative Materials Development

The global food industry faces challenges in safety, shelf life, and environmental impact. Traditional preservation and packaging materials are not eco-friendly. CD BioSustainable develops degradable smart preservative materials that monitor and interact with food or its environment to reduce spoilage. These intelligent, biodegradable solutions support food safety, quality, and circular economy goals.

Technical Principles

The development process of degradable smart preservative materials follows the guidelines of:

• Controlled Release Systems: Active ingredients (natural antimicrobials and other preservatives, antioxidants, ethylene scavengers) are encapsulated or embedded in the biocompatible polymer matrix. These compounds are released in a time-controlled manner, or in response to specific conditions (microbial growth, oxidation, increase in temperature, pH shift, enzymatic activity, etc.) to control the microbial activity, oxidation, or ripening of the fruit.
• Embedded bio-based or biodegradable sensors and indicators into the packaging material. These components are capable of detecting and signaling the alteration of food products or the package's integrity. Time-temperature indicators (TTIs), freshness indicators (detecting spoilage volatile compounds), oxygen and carbon dioxide sensors.
• The polymeric materials are chosen for their capability to undergo natural degradation into non-toxic substances such as water, carbon dioxide and biomass under specific conditions like composting, soil and marine environments, complies with global regulations such as ASTM D6400 or EN 13432.

Technical Classification

Our materials can be broadly classified into:

Degradable Active Preservative Materials: These materials actively interact with the food or the internal packaging atmosphere to extend shelf-life.

• Antimicrobial Releasing Systems: Incorporate natural or food-grade antimicrobial agents.
• Oxygen Scavenging Systems: Remove residual oxygen from the package.
• Ethylene Scavenging Systems: Absorb ethylene to slow down ripening in fruits and vegetables.
• Moisture Control Systems: Regulate humidity within the package.

Degradable Intelligent Preservative Materials: These materials monitor the condition of the food or the surrounding environment and communicate this information.

• Time-Temperature Indicators (TTIs): Visually indicate the cumulative temperature exposure of the product.
• Freshness Indicators: Signal spoilage through color changes or other detectable signals in response to microbial metabolites.
• Leakage Indicators: Detect breaches in package integrity.
