What causes my jars of fruit to lose liquid when I process them?
Loss of liquid during processing fruits may be caused by:
- Filling jars too full.
- Failure to work out air bubbles from jars before processing.
- Jars less likely to lose liquid if contents are packed hot rather than raw.
- Jars not covered with 1 to 2 inches of water in boiling-water- canner throughout processing period.
- Too much headspace.
Jars of food that have lost liquid during processing are safe to eat if no signs of spoilage are present. Do not open these jars to add more liquid after processing.
