Encapsulation of probiotics with GRAS polymers for enhanced gummy candy
Iowa State University presents a method to enhance probiotic viability in gummy candies using GRAS polymers. This encapsulation technique improves thermal stability and shelf-life while maintaining gummy quality, offering a scalable solution for food manufacturers.
Overview
Iowa State University has developed an innovative method to encapsulate probiotic bacteria in gummy candies using Generally Recognized As Safe (GRAS) polymers and gelation agents. This technique enhances the viability of probiotics during food processing and storage while maintaining the quality of the gummy matrix. The encapsulation process is designed to be scalable and compatible with existing gummy manufacturing conditions, making it an attractive option for food manufacturers looking to incorporate probiotics into their products.
Technical specifications
Encapsulation Process:
- Utilizes GRAS polymers such as alginate, pectin, agar, and high-amylose starch.
- Employs ionic gelation to create calcium alginate composite microparticles.
- Probiotics are mixed with the polymer dispersion and added to a calcium chloride solution to form stable microparticles.
- Microparticles are then incorporated into a pectin/gelatin matrix and dried to form gummy candies.
Benefits:
- Enhances thermal, structural, and physical stability of probiotics.
- Improves encapsulation efficiency and viability of probiotics.
- Potential for controlled release and improved shelf-life stability.
- Minimal impact on gummy texture and color.
Technology readiness level
This technology is currently at Technology Readiness Level 3. It has been demonstrated at a lab scale, and further optimization is planned to refine the process parameters and validate the encapsulation efficiency and probiotic viability in gummy candies.
