Does Spelt Flour Go Bad?
Understanding Shelf Life and Storage Tips
Spelt flour, like most flours derived from grains, can indeed go bad over time. As a whole grain flour, spelt contains natural oils that are prone to oxidation, which can lead to rancidity. The shelf life of spelt flour is influenced by how it's processed and stored. While refined flours may last longer due to the removal of the bran and germ where most oils reside, whole spelt flour has a shorter lifespan because these components are left intact, fostering a more nutritious yet perishable product.
Detecting spoilage in spelt flour generally involves engaging the senses. A fresh batch of spelt flour should have a mild, nutty scent. When it starts to emit a sour or unpleasant odor, it's a strong indicator that the flour is past its prime. Similarly, spelt flour's texture should be consistent and powdery. The presence of clumps, discoloration, or signs of moisture can all signify that the flour has been compromised.
Proper storage is paramount in preserving the quality of spelt flour. It is typically recommended to store it in airtight containers away from heat and light, which can accelerate spoilage. In some cases, refrigeration or freezing can greatly extend its shelf life by slowing down the degradation process. Consumers can use the best-by date as a guideline for optimal quality, but should also trust their senses to ascertain freshness.
