Microencapsulated antioxidant delivery systems for stabilizing natural colors
A precision-controlled microencapsulation platform that delivers natural antioxidants to protect natural colors from degradation caused by heat, humidity, light, oxygen, and pH stress. Demonstrated up to 4-fold stability improvement for astaxanthin, with proven results across zeaxanthin, anthocyanin, lycopene, lutein, and beta-carotene.
Overview
Natural colors are notoriously difficult to stabilize. Pigments such as astaxanthin, zeaxanthin, anthocyanin, lycopene, lutein, and beta-carotene degrade rapidly when exposed to heat, humidity, light, oxygen, and pH fluctuations, with challenges intensifying under demanding processes such as extrusion. This microencapsulated antioxidant delivery system addresses these limitations by providing precisely controlled release of natural antioxidants that shield colorants from degradation throughout production and shelf life, preserving vibrant appearance without synthetic additives.
The solution builds on Blue California's proprietary FineCap microencapsulation platform, enabling targeted, controlled-release antioxidant delivery. By tailoring release kinetics to each pigment's degradation pathways, the system maximizes protection while minimizing antioxidant dose, supporting clean-label formulations and cost efficiency.
Technical specifications
Microencapsulation embeds natural antioxidants in a protective matrix that releases them in a controlled manner, timed to counteract oxidative stress on the target colorant.
Key features:
- Controlled-release delivery tailored to individual pigment chemistries
- Demonstrated 4-fold stability improvement for astaxanthin
- Proven effective for zeaxanthin, anthocyanin, lycopene, lutein, and beta-carotene
- Protects against heat, humidity, light, oxygen, and pH stress
- Compatible with demanding processes such as extrusion
- Dosage can be tuned for predictable, linear stability gains
Technology readiness level
Validated through dozens of completed projects for external customers with consistent results across multiple pigment types. Prototype samples can be delivered for independent testing within 3 months of mutual agreement, enabling rapid validation in target applications.
