Necessity of vacuum sealing in canned food process:
Exhausting is allowing air or similar gases to escape from the food. In a sealed container oxygen is undesirable, whether it is released from food cells or is present in the form of entrapped air. Oxygen may react with the food and the interior of the can and affect the quality and nutritive value of the canned food. Other gasses, for example, carbon dioxide, should also be exhausted as much as possible. They may place undue strain on the container during the heat process as they will expand. This will be more of a concern in metal cans, where the gases will be hermetically trapped and have no means to escape.
