Abstract
Methods and apparatus for packaging whole or partially processed bulk, fresh products under modified atmosphere including placing such produce into bags or other containers for the produce, attaching to the opening at the top of each of the bags or containers a tube having an openable and closable lid, placing the bags or other containers with the tubes attached thereto inside a vacuum chamber, withdrawing air from the vacuum chamber from the bags or other containers until the oxygen concentration in the bags or other containers has reached a desired level, refilling the bags or other containers with one or more gases other than air while restoring the pressure inside the vacuum chamber and outside the bags or other containers at rates sufficient to minimize crushing or bruising of produce in the bags or other containers as the pressure in the vacuum chamber rises from the reduced level to a desired, ambient level.
