Factors Affecting Rye Flour’s Shelf Life
The shelf life of rye flour is primarily determined by the following factors:
- Type of Rye Flour: Whole-grain rye flour has a shorter shelf life than white or light rye flour due to its higher oil content.
- Storage Conditions: Moisture, heat, and light are the primary enemies of rye flour.
- Packaging: Airtight containers prevent moisture and oxygen from reaching the flour, extending its shelf life.
Shelf Life of Rye Flour in Different Storage Conditions
