Why it happens

Main causes

  • Overactive fermentation due to warmth
    At higher temperatures, vegetable tissues break down faster and fermentation can progress beyond the optimal stage.
  • Incorrect fermentation balance
    Improper salt levels or temperature can lead to unwanted microbial activity and slimy texture.

Next steps

  1. 1

    A clean sour smell may indicate a texture issue, while a rotten or sharply unpleasant odor means the product is unsafe.

  2. 2

    Slow down the process

    Move the product to a refrigerator or a cold place to slow fermentation and prevent further texture breakdown.

  3. 3

    Adjust the brine formula

    For the next batch, adjust salt levels, control temperature, and consider adding tannin-rich leaves to maintain a firmer texture.
