Incorporating Probiotics into Gum Base: Direct Addition vs. Encapsulation
Question
If I want to make gum with these probiotics included in the list of ingredients:
- Can I pour them directly into the gum base?
- Or do I need to encapsulate (cap) them first?
Answer
When incorporating Lactobacillus salivarius (200 billion/g) (Freeze-dried) into a gum base, the primary concern is maintaining the viability of the live bacteria. Here are the guidelines for your application:
1. Direct Addition vs. Encapsulation
You can technically pour the powder directly into the gum base, but it depends entirely on your processing temperature:
- Direct Addition: This is only recommended if the gum base is processed at a "cold" or "warm" temperature (ideally below 40°C). If the base is too hot when the probiotics are added, the heat will kill the bacteria, and you will lose the probiotic benefits.
- Encapsulation (Capping): If your manufacturing process requires high heat to melt the gum base, you must use encapsulated probiotics. Encapsulation provides a protective barrier against heat and moisture, ensuring the bacteria survive the production process and remain stable on the shelf.
2. Temperature Control (Critical)
Probiotics are living organisms. High temperatures are their greatest enemy.
- If you are adding the powder directly, wait for the gum base to cool down as much as possible while still remaining pliable before folding in the probiotic powder.
- Aim for a temperature below 35-40°C.
3. Moisture and Stability
Freeze-dried probiotics are activated by moisture.
- Ensure your gum base and other ingredients (like sweeteners or flavorings) have very low water activity.
- If the gum contains moisture, the probiotics may activate prematurely and then die, reducing the shelf life and efficacy of the product.
4. Recommendations for Best Results
- Mixing: Ensure the powder is distributed evenly throughout the gum base to provide a consistent dose per piece.
- Storage: Finished probiotic gum should be stored in a cool, dry place, ideally in moisture-barrier packaging (like blister packs or foil-lined pouches) to prevent the bacteria from degrading over time.
For oral health benefits, Lactobacillus salivarius is an excellent choice as it naturally inhabits the oral cavity and helps maintain bacterial balance. Maintaining its live count through careful processing is key to its effectiveness.
