Abstract
A method for the assessment of the product shelf life in a package, and a device for accelerating the permeation of a test gas into a package. To significantly reduce the test time and to accelerate the permeation of a test gas, and in order to supply realistic results of the time-dependent permeations into the charged product in a simple manner, a closed package filled with charged product is placed in an overpressure chamber, and stored in the overpressure chamber over a specified time period under overpressure and at a specified temperature in a test gas atmosphere, wherein a defined amount of test gas permeates into the package. The package is stored over a certain time period under the influence of heat and/or light and then the charged product is subjected to analytical and/or sensory examination. The device includes an overpressure container for the accommodation of at least one package with a closable inlet opening, a gas inlet for feeding the test gas, a gas outlet for discharging the test gas, and a device for setting and maintaining an overpressure.
