Powdered probiotics are created so that they will stay alive. After the probiotics are made, there are several techniques used to protect them.
- The bacteria are freeze-dried in tightly controlled conditions so no outside moisture or oxygen comes into contact.
- Then the bacteria are coated with a cryoprotectant before freezing and this protects the cells in harsh temperatures.
- The bacteria are stored with vitamin C and prebiotic fibers, which provide a stable medium for bacteria. These two ingredients are also present in Kura.
Continued stability and viability is dependent on limiting the exposure to stimulating environmental conditions like warmth and moisture.
