Why, after canning, turn the jars upside down?

The idea behind turning the jar upside down is that the jam or jelly, which should still be at a temperature high enough to kill any microorganisms that would cause spoilage, will sterilize the underside of the sealing disc as well as the small quantity of air that is trapped beneath the lid. If the jars are heated and the contents are at least 165 degrees Fahrenheit or 74 degrees Celsius, then a vacuum might occur.

How long should canning jars be left upside-down?

Inversion canning is a method of canning that involves pouring hot canning materials (typically jams or jellies) into jars, securing the lid, and then turning the cans upside down on a towel for approximately five minutes.

What happens if air bubbles aren’t taken out before canning?

“If the air bubbles are not eliminated, the air that is retained within the meal will, in effect, contribute to the volume of the headspace. Seals might fail if there is an excessive amount of headspace.” When moving the contents in order to eliminate headspace, choose tools made of wood or plastic (like Ball’s official “bubble freer,” which is illustrated here).

The process of canning causes the air that is trapped in the headspace of the jar (that is, the space between the bottom of the lid and the top of the food) to be expelled.
