unopened pantry6-12 months past 'best by' date
Signs of Spoilage
Significant off-odors (rancid, chemical), visible mold (extremely rare), signs of pest infestation.
How to Check
Check the 'best by' date as a guideline. Inspect the packaging for any tears, holes, or signs of tampering. Upon opening, sniff for any unusual or unpleasant smells before tasting. If it smells like old oil, paint, or is overtly bitter, it's likely rancid.
Storage Tips
While 'best by' dates indicate peak quality, unopened corn chips can remain safe to eat for an extended period if stored properly. The primary concern is the oils becoming rancid over time, which affects flavor more than safety. Keep away from direct sunlight, heat sources, and areas with high humidity.
opened pantry1-2 weeks for optimal crispness and flavor; up to 3-4 weeks before significant staleness/rancidity
Signs of Spoilage
Loss of crispness (stale, soft, chewy texture), off-flavors (bitter, sour, 'old oil'), rancid smell (like old crayons, paint, or soapy), visible mold (rare but possible if exposed to excessive moisture), signs of pests.
How to Check
-
Visual Inspection: Look for any discoloration, fuzzy spots (mold), or signs of insect activity.
-
Touch Test: Feel the chips. They should be firm and crisp. If they feel soft, bend easily, or are chewy, they are stale.
-
Smell Test: Sniff the chips for any off-odors. A strong, unpleasant, or chemical-like smell indicates rancidity.
-
Taste Test: If no other signs are present, taste a small piece. A bitter, sour, or 'off' taste means they are past their prime.
Storage Tips
Proper sealing is crucial to extend freshness once opened. Use an airtight container, a zip-top bag, or seal the original bag tightly with a clip. Exposure to air and moisture is the main cause of staleness and rancidity. Do not refrigerate or freeze corn chips, as the humidity in these environments can cause them to absorb moisture, leading to staleness and a loss of crispness even faster.
