GRAS-polymer nanoparticles for enhanced vitamin delivery
Innovative GRAS-polymer nanoparticles designed for improved absorption and controlled release of fat-soluble vitamins in VMS products. Using alginate, pectin, zein, and cyclodextrin, this scalable solution enhances bioavailability and shelf-life stability.
Overview
This innovative solution utilizes GRAS-polymer nanoparticles to enhance the bioavailability and controlled release of fat-soluble vitamins within vitamins, minerals, and supplements (VMS) products. By combining alginate, pectin, zein, and cyclodextrin, this method ensures efficient encapsulation and improved absorption, overcoming common challenges in vitamin delivery. The result is a scalable and cost-effective approach with potential applications in dietary supplements and fortified foods.
Technical specifications
The technology employs a two-step ionic gelation and encapsulation process at room temperature. The nanoparticles are fabricated using blends of alginate, pectin, zein, and cyclodextrin, optimized for size and vitamin content. Key features include:
- Use of GRAS (Generally Recognized As Safe) polymers for safe consumption
- Enhanced encapsulation efficiency and controlled release properties
- Compatibility with fat-soluble vitamins such as A, D, E, and K
- Stability under various environmental conditions including buccal and GI tract simulations
- Freeze-drying process to create stable powder formulations
Technology readiness level
The technology is currently at TRL 3, with initial experimental proof of concept completed. Future work involves optimizing the nanoparticle formulation and conducting controlled release studies in simulated oral and GI environments.
