Abstract
Air-containing packages are subjected to heat sterilizing under pressure in a sterilization treatment tank. A pressure controlling method comprises changing the rate-of-rise of the temperature in the treatment tank in the vicinity of a point-of-change in a pressure rise in a pressure pattern in the package and delaying the timing of lowering the pressure in the treatment tank after the start of cooling treatment to avoid any deformation of the packages.
