Expiration & Storage Tips
When does tapioca flour expire?
Unopened, this fine-grained flour has a lengthy shelf life and can stay fresh for about 2 years when stored in a cool, dry place. Interestingly enough, the printed date on the package is often a conservative 'Best By' date that does not mark the actual expiry. Once opened, tapioca flour can be kept for about a year if stored properly. Freezing is not generally recommended for flour like this one; however, if you do choose to freeze it to extend its life, be sure to allow it to thaw at room temperature before use.
How do you tell if tapioca flour is bad?
Spotting bad tapioca flour is simple. First, give it a good smell. A stale, sour, or rancid smell is a clear indication it has gone bad. Next, inspect the flour for any discoloration, grey or odd colors could mean the flour has spoilt. Lastly, watch out for any form of mold or bugs, which can creep into improperly sealed containers.
Tips for storing tapioca flour to extend shelf life
• Keep it tightly sealed: After every use, make sure the flour is stored in an airtight container. Tapioca flour loves to absorb moisture from the air, which can lead to clumping or spoilage.
• Store in a cool, dry area: A pantry, drawer or kitchen cabinet (away from the stove, dishwasher or refrigerator) serve as the best places for storing your flour.
• Watch out for cross-contamination: If you're using your flour for gluten-free cooking or baking, make sure it's stored away from wheat flours and other gluten-containing items.
