Methods for the determination of residual peroxide in packaging

The VDMA document no. 01 “Methods for the determination of residual peroxide in packaging - Test procedures” from the VDMA Food Processing and Packaging Machinery Association has been completely revised and is now available for free download in German and English. It explains test procedures for methods for the determination of residual peroxide in packaging.

The determination of the residual peroxide content in empty packaging is part of the routine tests on hygienic filling machines of VDMA hygiene classes III, IV and V for liquid food that use sterilizing agents based on hydrogen peroxide. The document no. 01 of the VDMA Food Processing and Packaging Machinery Association describes the methods for determining the residual peroxide content in empty packaging that has been sterilized in or before filling machines of VDMA hygiene classes III, IV and V for liquid food using sterilization media containing hydrogen peroxide. The measurements ensure that the sterilized packaging placed on the market does not have a negative impact on the product quality.

In contrast to the previous versions and in addition to the description of the analysis methods, detailed information is given on correct sampling and possible influences on the measurement. The instructions apply both to machine validation and to routine testing by the machine operator or quality assurance during operation.

This publication has been completely revised by the VDMA working group "Interface problems in aseptic plants" of the VDMA Packaging Machinery Division.
