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 can you tell if you canned food properly?

In order to guarantee a vacuum seal on a jar, it is essential to leave the recommended amount of headspace inside the container. When air is squeezed out from beneath the lid during processing, the food may expand and bubble out if there is not enough headspace left in the container to accommodate the expansion.
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. This allows the jars to cool in an inverted position, which aids in the preservation process. Once the five minutes have elapsed, the jars are turned back over so that the seals can form while they are allowed to cool and (hopefully) seal.

False seals develop when the items are canned improperly, when the rims of the jars are not cleaned before processing, or when the jars are not filled appropriately. When hot food is put into jars, the lids are then placed on the jars, but the jars containing the product are not heat processed, this is one of the most prevalent situations in which a false seal develops.
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).
What are the top five indicators that home canned food is spoiled?

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. Because air is unable to freely escape from containers with lids that are too tight, the air eventually forces its way out, which causes the lid to deform. This results in an effect that can be described as buckling or crinkling.
