To prevent the pickling water from becoming turbid, you can take the following measures:

1. Choose high-quality cucumbers: Choose fresh, undamaged cucumbers as pickling materials. Make sure there are no soft or rotten parts on the surface of the cucumber.

2. Clean the cucumbers thoroughly: Wash the cucumbers thoroughly with water to remove dirt and pesticide residues on the surface. You can use a brush to gently scrub the surface of the cucumber.

3. Thickening process: Before pickling the cucumbers, blanch the cucumbers in boiling water and then take them out immediately. This step helps kill bacteria and improves the texture of the cucumber.

4. Use clean containers and tools: When pickling cucumbers, use clean glass bottles or containers to avoid impurities or contaminants entering the pickling liquid. Also use a clean spoon or tongs to prevent cross-contamination.

5. Control the proportion of salt and vinegar: The proportion of salt and vinegar in the pickling liquid should be moderate and follow the proportion of pickled ingredients. Too much salt and vinegar can cause the liquid to become cloudy.

6. Sealed storage: Place the pickled cucumbers in a clean, sealed container. Make sure the container is well sealed to prevent outside air and bacterial contamination.

7. Storage conditions: Store pickled cucumbers in a cool, ventilated, dry place to avoid high temperature and humid environments. This can extend the storage period and keep the water clear.
