Signs of Spoilage in Cassava Flour

To ensure the safety and quality of your cassava flour, it's essential to be able to identify signs of spoilage. Here are some indicators that your cassava flour may have gone bad:

1. Off Odor

  • Normal Odor: Fresh cassava flour should have a mild, slightly sweet odor.

  • Mold growth can appear as fuzzy spots or discoloration, indicating that the flour is no longer safe to consume.

3. Strange Texture

  • If you notice clumps, moisture, or an unusual texture, it may be a sign of spoilage.

4. Taste Test

  • While not recommended, if you are unsure about the quality of your cassava flour, you can perform a small taste test.
  • If the flour tastes sour, bitter, or off, it's best to discard it.

5. Expiration Date

2. Avoid Direct Sunlight

  • Store cassava flour away from direct sunlight, as UV rays can degrade the quality of the flour.

3. Seal Properly

  • Ensure the container or packaging is tightly sealed after each use to prevent moisture and air from entering.

4. Use Freshness Indicators

  • Consider using freshness indicators such as silica gel packs to absorb moisture and extend the shelf life of cassava flour.
