Shelf Life of Oat Flour
The shelf life of oat flour depends on several factors, including the type of flour, storage conditions, and packaging. Generally, oat flour has a longer shelf life compared to other flours due to its lower moisture content.

- Packaged Oat Flour: Commercial oat flour packages usually have a “best by” date, indicating the recommended time frame for optimal quality.
Storage Conditions
Proper storage plays a vital role in preserving the shelf life of oat flour. Here are some essential tips:
- Airtight Container: Store oat flour in an airtight container to prevent moisture and pests from entering.
