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.
