Why it happens

Main causes

  • Raw ingredient characteristics
    Ripeness, variety, and moisture content can significantly affect the result, even when following the same recipe.
  • Minor process mistakes
    Packing density, processing temperature, drying time, or small deviations in proportions can collectively lead to issues that appear unexpectedly.
  • Storage conditions
    Light, heat, moisture, poor-quality containers, or repeated opening can spoil even a well-prepared product.
What to do

Next steps

  1. 1

    Check safety first

    Smell, gas release, foam, slime, mold, or a leaking lid are more important indicators than a single symptom.

  2. 2

    Distinguish texture issues from spoilage

    Not every defect indicates spoilage: sometimes it is only a texture change or clumping that does not affect safety.

  3. 3

    Document your observations for the next batch

    Recording the variety, drying time, batch size, and storage conditions will help identify the root cause and avoid the issue in future batches.
