Understanding the Shelf Life of White Rice Flour

- Storage Conditions: Store white rice flour in a cool, dry place away from direct sunlight and heat. Moisture and temperature fluctuations can shorten its shelf life.
- Additives: Some commercial rice flours may contain preservatives or other additives that extend their shelf life.

Signs of Spoiled White Rice Flour
Spoiled white rice flour may exhibit the following signs:
