Propolis tinctures require specific storage conditions to maintain their potency and shelf life. Key factors include using dark, airtight containers to protect from light and oxidation, storing in cool environments away from heat sources, and ensuring the alcohol concentration remains adequate for preservation. Proper storage prevents degradation and preserves the tincture's therapeutic properties.
Key Points Explained:
-
Container Selection
- Dark Glass Bottles: Amber or cobalt blue glass blocks UV light, which can degrade propolis compounds. Plastic should be avoided as it may interact with alcohol.
- Airtight Seals: Prevents evaporation of alcohol (the preservative) and oxidation. Screw-top lids with silicone seals or dropper bottles work well.
-
Storage Environment
- Temperature: Keep in a cool, stable place (15–25°C/59–77°F). Avoid heat sources like stoves or direct sunlight, which accelerate chemical breakdown.
- Humidity: Low-humidity areas prevent label damage and mold risk. A pantry or cupboard is ideal.
-
Alcohol Integrity
- Minimum 130-Proof Alcohol: Ensures preservation; lower concentrations risk microbial growth. Food-grade ethanol (like vodka or Everclear) is safe for internal use. Never use denatured alcohol or rubbing alcohol.
- Regular Checks: Inspect for evaporation or sedimentation. Top up with high-proof alcohol if levels drop significantly.
-
Handling Practices
- Shake Before Use: Reduces sedimentation and ensures even potency.
- Clean Tools: Use sterilized droppers or spoons to avoid contamination.
-
Shelf Life
- 2–3 Years: When stored correctly. Discard if color darkens excessively, smells rancid, or shows mold.
For sourcing high-quality propolis, consider a propolis collector who ensures raw material purity. Proper storage maximizes both safety and efficacy, making it a critical step for purchasers and end-users alike.
