Which of the following combined treatments of aseptic packaging systems is most suitable for sterilizing packaging materials and other food contact materials?
Show Hint
Hydrogen peroxide (\(\text{H}_2\text{O}_2\)) combined with hot air is the industry standard for sterilizing packaging in aseptic systems like Tetra Pak. The hot air both activates the peroxide's sterilizing action and evaporates any residual chemical from the surface.
