However, many home cooks wonder, “Does oat flour go bad?” In this comprehensive guide, we’ll delve into the factors that affect oat flour’s shelf life, signs of spoilage, and storage tips to ensure your oat flour remains fresh and safe to consume.

Shelf Life of Oat Flour

The shelf life of oat flour depends on several factors, including:

Oat flour can go bad, and it’s essential to recognize the signs of spoilage to avoid consuming contaminated food. Here are some indicators:

• Mold: Visible mold growth on the oat flour is a clear sign of spoilage.
• Rancid smell: Oat flour that has gone rancid will have an unpleasant, sour odor.
• Sour taste: If oat flour tastes sour or bitter, it has likely spoiled.
• Bugs: If you notice any insects or larvae in the oat flour, discard it immediately.
