After vacuum sealing why it need to put into Retort ?

Jars or cans are heated to a temperature high enough to destroy the microorganisms that could cause food spoilage and/or foodborne illness. The heating process also removes air from the product and creates a vacuum. This vacuum helps prevent recontamination by harmful microorganisms.
