Understanding Corn Flour’s Shelf Life
Corn flour, like all pantry staples, has a finite shelf life. Its lifespan primarily depends on two factors:

The approximate shelf life of corn flour varies depending on the type and storage conditions:
- Whole-Grain Corn Flour: 3-6 months in the pantry, 6-12 months in the refrigerator
- Refined Corn Flour: 6-12 months in the pantry, 12-18 months in the refrigerator

Detecting spoiled corn flour is crucial to ensure food safety. Look out for these telltale signs:
