UHT / Aseptic Processing
Commonly CCPAlso: ultra-high temperature · aseptic packaging · tetra-pak processing
Ultra-high temperature treatment (typically 135–150°C for 2–5 s) followed by aseptic filling into pre-sterilized packaging. Shelf-stable without refrigeration.
Typical Hazards
- BBiologicalSterility breach via packaging or fill zone; biofilm in holding tube
- CChemicalCleaning chemical residue, foam-control agent
- PPhysicalFragments from fill nozzle, packaging material
Typical Controls
- Sterilization-in-place (SIP) of fill zone before each run
- Holding-tube residence time validation
- Pre-sterilization of packaging (peroxide, peroxide-UV)
- Differential pressure on fill zone (positive)
- Microbiological incubation testing of finished product
