Alginate-based probiotic encapsulation for low ph beverages
PERKii offers an advanced alginate-based encapsulation technology that enhances probiotic viability in low pH beverages. This solution enables large-scale production, maintaining probiotic counts of 1 billion CFU/serve for up to 3 months, with potential for international expansion.
Overview
PERKii presents an innovative alginate-based encapsulation technology designed to protect probiotics in low pH environments, such as acidic beverages and the stomach. This technology ensures the survival and delivery of probiotics by forming alginate microgels that encapsulate the probiotics, safeguarding them from acidic conditions. The encapsulated probiotics are then released in the small intestines where the pH is higher, ensuring effective delivery and health benefits.
Technical specifications
- Alginate encapsulation: Cross-linking sodium alginate with divalent metal ions to form protective gels.
- Microgel size: Achieves encapsulation in microgels sized 20-80 microns, allowing for large-scale production.
- Probiotic viability: Maintains 1 billion CFU/serve in non-dairy, low-sugar beverages for up to 3 months.
- Future enhancements: Current research focuses on freeze drying to extend shelf life, addressing challenges in maintaining probiotic viability during the process.
Technology readiness level
This technology is at TRL 9, having been successfully launched in the Australian market since 2016. PERKii is exploring international expansion and seeking technical support for further research into shelf-life extension through freeze drying.
About PERKii
PERKii is an Australian food and beverage company known for developing the world's first non-fermented, low-calorie probiotic drink. The company utilizes proprietary micro-shield technology, originally developed at the University of Queensland, to encapsulate live probiotics in natural alginate beads. This micro-encapsulation system is designed to protect the probiotics from harmful stomach acid and ensure they reach the gut alive, where they are released and can proliferate. Unlike traditional fermented or dairy-based products, PERKii’s drinks provide a shelf-stable environment for the probiotics by balancing moisture, temperature, and nutrients within the beverage packaging.
The company serves health-conscious consumers looking for functional drinks that support digestive health, immune function, and overall wellness. By solving the challenge of probiotic survivability in beverages, PERKii offers a scientifically backed, pleasant-tasting alternative to traditional probiotic supplements. The brand has achieved wide commercial availability across Australian supermarkets and retail outlets, and it continues to expand its product line with options like sparkling probiotic drinks. In 2023, PERKii integrated the technology developer ProGel as a wholly owned subsidiary to further solidify its market position and innovation capabilities in the functional beverage sector.
