If marinade leaks from an inverted can, this means. that the cover is not closed and conservation can deteriorate.
“Hot sterilization inside the can creates a pressure that can raise the cover if it is not rolled properly. Turning the jar helps to eliminate this pressure,” the article says.
In addition, in an inverted position, the cover is inside, contacting the contents of the can.
“This creates an additional sterilization effect that can destroy microbes that have fallen on the lid while rolling,” the publication says.
Turning the jar also helps to strengthen the vacuum seal and make it more reliable, and also prevents the deformation of the lid.
“If the bank cools unevenly, the lid can be deformed. This can lead to loss of tightness and damage to conservation. Turning the jar helps to distribute heat more evenly,” the article noted.
