How to validate UHT equipment? Equipment performance validation? Sterilization effect validation and process parameter compliance validation. Can you provide a document?

Hi zuoli,

 

I normally use Tetra Pak Guidelines for Microbiological Evaluation of Commercially Sterile Products. The flow chart from the guidelines is shown below.

 

Attached File  Tetrapak Flow Chart for Microbiological Test Procedure.png   508.63KB   0 downloads

 

The protocol prescribes incubating products at 30°C and 55°C.

 

It is also a good idea to implement a system for early detection of severe failure - ATP test after 3 day’s incubation. This should be retained as normal following the sterility test.

 

You could also use ATP at 7 days if you are reducing incubation from 10 days.

 

You might find info in these topics useful:

Kind regards,
