Shelf Life of Unbleached Flour
Unbleached flour has a relatively long shelf life compared to other types of flour. When stored properly, it can last for up to 12 months. However, factors such as storage conditions and exposure to elements can affect its longevity.
Factors Affecting Shelf Life
- Moisture: Moisture is the primary enemy of flour. Damp conditions can cause mold growth, rendering the flour unsafe for consumption.
- Heat: High temperatures can deteriorate the flour’s quality and shorten its shelf life.
- Light: Exposure to light can break down the nutrients in flour, affecting its flavor and baking performance.
- Insects: Insects can infest flour, contaminating it and reducing its shelf life.
Proper Storage for Extended Shelf Life
To extend the shelf life of unbleached flour, follow these storage guidelines:
- Airtight Container: Store flour in an airtight container to prevent moisture absorption and insect infestation.
- Cool and Dry Place: Choose a cool, dry location with a constant temperature. Avoid storing flour in areas with high humidity or temperature fluctuations.

Signs of Spoiled Flour
If you suspect that your unbleached flour has spoiled, look for the following signs:
- Clumps: Clumping indicates moisture absorption, which can lead to mold growth.
- Mold: Visible mold growth is a clear sign of spoilage.
