Understanding Flour’s Composition
All purpose flour, a versatile ingredient, is milled from wheat and consists primarily of starch and protein. Starch provides the flour with its thickening properties, while protein forms the gluten network responsible for dough’s elasticity.
Factors Affecting Flour’s Shelf Life
Several factors influence the shelf life of all purpose flour, including:
- Exposure to Light: Light can break down the nutrients in flour, reducing its quality and shelf life.
- Moisture: Excess moisture can promote mold growth, spoiling the flour.
- Temperature: High temperatures accelerate the degradation of flour, while cold temperatures slow it down.
- Storage Method: Proper storage in airtight containers helps prevent contamination and extend shelf life.
Shelf Life of All Purpose Flour
Under optimal storage conditions, unopened all purpose flour can typically last for:
- Unbleached Flour: Up to 12 months
- Bleached Flour: Up to 6 months
Signs of Spoiled Flour
If flour has gone bad, it may exhibit the following signs:

Extending the Shelf Life of Flour
In addition to proper storage, there are other methods to extend the shelf life of all purpose flour:
- Freezing: Freezing flour can extend its shelf life by up to 2 years.
- Refrigeration: Refrigerating flour can slow down the degradation process, extending its shelf life to several months.
