What is AAP advanced aseptic processing?

Last Updated:

Advanced Aseptic Processing (AAP) techniques are physical barrier methods of product protection and containment that are used during manufacturing operations to separate (primarily) operators from the process. These methods are most often used during open processes or other critical process steps to ensure the product is not exposed to viable organisms and particulate contamination.Curtained cleanroom areas are also not within this definition, as curtains provide little real barrier from ingress. Only complete, rigid wall enclosures fall within the scope of AAP.
