Probiotic encapsulation using green materials and supercritical CO2 technology
Innovative encapsulation technology using green materials and supercritical CO2 improves probiotic stability and viability in low pH environments. Ideal for beverages, this method enhances probiotic efficacy and shelf life, leveraging natural, cost-effective materials.
Overview
Probiotic encapsulation using green materials and supercritical CO2 technology offers a groundbreaking solution to improve the stability and viability of probiotics in acidic environments, such as beverages. Traditional methods like spray drying and freeze drying expose probiotics to high temperatures or vacuums, reducing their effectiveness. This new approach utilizes natural, vegetable-based materials for encapsulation, which are not only cost-effective but also enhance probiotic survival rates and control release in low pH conditions.
Technical specifications
Key features:
- Utilizes vegetable-based, natural encapsulation materials
- Employs supercritical CO2 technology for low-temperature, low-pressure processing
- Enhances stability and viability of probiotics in acidic and gastrointestinal environments
- Compared with traditional methods, supercritical CO2 encapsulation offers improved microparticle stability and is easy to separate post-process
Technology readiness level
Currently at Technology Readiness Level 2, this technology is in the early evaluation stage. Extensive testing is planned to assess the efficacy of various vegetable-based materials and encapsulation methods, including spray drying, freeze drying, and supercritical CO2. Future steps include commercial testing in beverages to evaluate probiotic stability and effectiveness during shelf life.
