Sodium BicarbonateShelf Life, Storage, and Spoilage Guide
Pantry
Indefinite if kept dry
Store in a cool, dry place (below 75°F/24°C) in an airtight container. Keep away from moisture and strong odors. While safe indefinitely, its leavening power may diminish after 6-12 months once opened.
Refrigerator
Not recommended for storage
Not typically stored in the refrigerator as moisture can cause clumping and reduce effectiveness. If stored, ensure it is in an airtight, moisture-proof container.
Freezer
Not recommended for storage
Not typically stored in the freezer as moisture can cause clumping and reduce effectiveness.
Signs of Spoilage
- Significant clumping (indicating moisture absorption)
- Unusual or off-odors (if it has absorbed strong smells from its environment)
- Discoloration
- Presence of foreign matter or pests
Room Temperature Safety
Not applicable to dry, shelf-stable ingredients.
Store in a cool, dry place at room temperature, away from direct sunlight and moisture.
Safe Handling
Keep dry to prevent clumping and maintain effectiveness.
Use clean, dry utensils when scooping.
Ensure container is tightly sealed after each use.
While generally safe, avoid direct inhalation of powder.
