A frequently asked food preservation question is what causes liquid to be lost from the jar during processing? And is that product safe when it occurs?
There are many reasons why liquid loss can occur in food preservation, check out https://go.unl.edu/canning-liquidloss for causes and possible solutions if you are experiencing this in your home canned goods.
The National Center for Home Food Preservation assures us: “If all processing variables are accurate, less than half of the liquid is lost and the jars have sealed, do not open to replace the liquid. Use those jars first. If more than half of the liquid in the jar is lost, the food may not be adequately processed. In this situation, break the seal, refrigerate the jars, and use within 2 to 3 days.” #UNLFoodSafety
