Abstract
The present invention relates to a method of heating a package, comprising the steps of: placing a number of packages in a retort, pressurising the retort to a first pressure by the supply of a gaseous pressurisation medium of low moisture content, supplying a heating medium for heating the package and the product packed in the package, raising, in connection with the supply of the heating medium, the pressure in the retort to a second pressure, and, during the final phase of the heat-treatment, reducing the pressure in the retort in such a manner that the pressure of the product packed in the package is higher than or equal to the pressure prevailing in the retort outside the package.
