Why is the liquid in the jars cloudy?
Sometimes a cloudy liquid indicates that the food is spoiled, so recheck your canning recipe to be sure that its from a current and reliable source and that you followed the recommended processing method, time, and temperature. However, sometimes, a cloudy liquid comes from starch in over mature, starchy vegetables, such as corn, or from minerals present in soft water. Fillers in table salt also can cause clouding, so use pure refined salt when possible.
