In this comprehensive blog post, we will delve into the intricacies of oat flour’s shelf life, storage conditions, and spoilage indicators.
Understanding Oat Flour’s Shelf Life
Unopened oat flour generally has a lengthy shelf life, ranging from six months to one year. This extended lifespan is attributed to the low moisture content and natural antioxidants present in oat flour. The airtight packaging further contributes to its stability.
Factors Affecting Shelf Life
While unopened oat flour boasts an impressive shelf life, certain factors can influence its longevity:

To maximize the shelf life of unopened oat flour, follow these storage guidelines:
- Airtight Container: Transfer oat flour to an airtight container to prevent moisture and oxygen exposure.
