Microbial Product Stability Using Membrane Filtration

Food and Beverage | Pall Corporation webinar series

Microbial Retention and Integrity Testing for Food & Beverage Filters


Protecting your food and beverage production from pathogens and/or spoilers is mission-critical to ensure product quality that protects your brand. A key task of final membrane filters is to remove contaminants and provide microbiologically stable finished product.


Final membrane filters available in the marketplace offer a wide variety of microbial retention performance which is critical to understand. Parameters such as microorganisms for challenge testing, challenge level and type of performance claims are sometimes misunderstood.


Food & Beverage manufacturers with strong HACCP programs monitor final filters with an integrity testing method that provides assurance of filter performance in the customer’s process. This non-destructive integrity testing is directly correlated to the ability of a filter to retain microorganisms.  


Integrity testing helps manufacturers avoid issues such as product contamination, product losses, reprocessing and production delays, as well as satisfying auditor requirements for critical microorganism reducing/removing steps.


In our webcast, “Microbial Product Stability Using Membrane Filtration”, you’ll learn:


  • How final membrane filtration protects your product quality

  • How integrity tests confirm microbial reduction and sterilizing capabilities of filters


How selection of a filter affects risk of contamination
