Procedure for assessing product shelf life in a package

摘要

Evaluation of product storability in a package involves (A) storing a package (4) filled with a material in a pressurized chamber for a time t 1at pressure p 1and temperature T 1, the chamber containing a test gas such that a definite amount Q of the gas permeates into the package; then (B) storing package (4) for a time t 2under the influence of heat and/or light; and, finally, (C) analyzing and/or sensorally examining the filled material. An independent claim is also included for an apparatus (10) for accelerating the permeation of a test gas into a filled and closed package (4) so as to evaluate a product storability, the apparatus comprising (A) a pressurized chamber (1) with a closeable opening (9) for the package (4); (B) an inlet (2) and an outlet (3) for the test gas; and (C) a device (2, 6, 7, 10) setting and maintaining the super-pressure.
