Factors Affecting Shelf Life
The shelf life of almond flour is influenced by several factors, including:
- Storage Conditions: Proper storage is key to preserving the freshness of almond flour. Store it in an airtight container in a cool, dry place away from direct sunlight and heat.
- Exposure to Air: Almond flour oxidizes when exposed to air, which can shorten its shelf life. Minimize exposure by keeping it in an airtight container.
- Moisture: Moisture can cause almond flour to spoil. Keep it away from humid environments and avoid storing it in the refrigerator, as condensation can occur.
- Packaging: The type of packaging can also impact shelf life. Vacuum-sealed or nitrogen-flushed packaging helps prevent oxidation and extend shelf life.

- Store Properly: Keep almond flour in an airtight container in a cool, dry place.
- Avoid Exposure to Air: Minimize exposure to air by keeping the container tightly sealed.
- Use Vacuum-Sealed Packaging: Vacuum-sealed or nitrogen-flushed packaging significantly extends shelf life.
- Refrigerate or Freeze: Refrigeration or freezing can further extend shelf life, especially for opened packages.
- Discard Spoiled Flour: If almond flour shows signs of spoilage, discard it immediately.
